Dear RPBO friend,
October 18th was the final day of the 2004 season (our 11th) at
the Rocky Point Bird Observatory, marked by many single-season
records being set:
1. Total captures at 4051 new birds banded (eclipsing the record
set in 2003 by more than 300 birds)[note this is an unofficial
total as data is still being proofed];
2. 19 species set new banding highs for a season [Cooper,s Hawk,
Downy Woodpecker, Cassin,s Vireo, Hutton,s Vireo, Steller,s Jay,
Red-breasted Nuthatch, House Wren, Ruby-crowned Kinglet, Swainson,s
Thrush, Hermit Thrush, Varied Thrush, Orange-crowned Warbler,
Yellow Warbler, Spotted Towhee, Fox Sparrow, Lincoln,s Sparrow,
White-crowned Sparrow, Golden-crowned Sparrow, and Purple Finch
with Yellow Warbler and Golden-crowned Sparrow the biggest "winners
vs. their long-term averages];
3. On September 19, a new single day banding high with 203 birds
banded was truly amazing (or 210 with canopy net captures).
All this is made more significant in recognizing that our daily
effort has not changed compared to the previous five seasons,
and we also lost more days/net-hours to rain this year compared
to 2003. Our average capture/day rate picked up dramatically after
a slow start in July and August, and represents about 46 new birds
banded/day. And if we include the MAPS banding numbers, non-standard
banding numbers, hummingbird banding (28), and the owl banding
(411), we banded almost 5000 birds in 2004! That is quite an accomplishment!!
Furthermore, six days in September were marked by 100 or more
birds banded (these days alone represent 20% of total captures
for season!). There is little doubt that for most species 2004
was a good breeding year (the question remains: are most of our,
birds from Vancouver Island/south-western BC, or they also from
interior sites in province, and we also know some are from even
further north to Yukon and Alaska?). By far, one of the main banding
highlights remains the Rose-breasted Grosbeak banded on July 18th
during a volunteer banding workshop just before start of season
-- this is only Victoria's fifth record and RPBO's first, and
the bird remained in the area to at least August 4th. Three new
birds were also banded this year: Rose-breasted Grosbeak (July
18), Red-breasted Sapsucker (September 19), and Anna,s Hummingbird
(October 18). 95 species in total have ended up in our nets since
1994.
Our nocturnal owl banding project began its third season September
24th, and by November 10 ended up banding 403 Northern Saw-whet
Owls and 8 Barred Owl (new records for both species). And, with
assistance from Cam Finlay, our hummingbird banding project continued
for its second season 27 Rufous Hummingbirds were banded at RPBO,
which is well behind last year's capture rate, but on the final
day of the season (October 18) we banded Rocky Point,s fourth
Anna,s Hummingbird! (note separate banding data set for both of
these projects).
However, this good news is tempered by low banding numbers this
year for American Goldfinch (our lowest ever), Chipping Sparrow
(interestingly, we set a high for them in 2003), Savannah Sparrow
(lowest since 1998), and Wilson,s Warbler (lowest since 1998).
Long-term declines are also now quite evident for Savannah Sparrow.
Furthermore, we did not band any swallows during this season (first
time since 1997).
In addition, index cards for 408 birds of 39 species among own
re-traps were processed (including 37 birds from previous years).
Among these 37 "old birds, two birds represent 5+ year-old
birds (a Puget Sound White-crowned Sparrow and an Oregon Dark-eyed
Junco). However, two other retrap records stand out in particular.
First, on September 9 we recovered a Chestnut-backed Chickadee
that had originally been banded on June 4 at our Royal Roads University
MAPS site! Who says that Chestnut-backed Chickadees do not "migrate
or at least disperse over a large area, as this is a distance
of approximately 13 kilometres?! Needless to say, the re-trap
highlight of the year (decade?!) was the recapture on September
18 of a Chestnut-backed Chickadee (CBCH) originally banded as
an After-Hatch Year (AHY) at RPBO on August 2, 1997 by the late
Beverley Glover (band number 2120-06883). This record establishes
a new NORTH AMERICAN longevity record for this species at 8 years,
3 months! We checked our records and the files at the Bird Banding
Lab (BBL) at the Patuxent Wildlife Research Center in Laurel,
Maryland (the main repository for all of North American banding
data). As well, this bird has now been re-trapped a total of 7
times, but interestingly not since 2001. If one does the math,
this CBCH is now the oldest on file (note the BBL arbitrarily
uses June 1st as all birds, "birthday as we cannot know for
certain its exact birthday of course in other words, it was at
least 1 year, 2 months old when originally caught). The previous
record on file at BBL was 7 years, 9 months. For those interested,
visit the Bird Banding Lab,s longevity pages: http://www.pwrc.usgs.gov/BBL/homepage/longvlst.htm.
It is fitting that Bev,s contributions to RPBO live on
Among the rarities recorded: a Tufted Puffin was spotted during
seawatch on July 22, and individual Brown Pelicans were recorded
at Pedder Bay on July 24 and July 30 and again on September 5th
west of Bentinck Island. By far, the rarest bird of the season
was the Manx Shearwater found in the afternoon by boat about 5
km east of Race Rocks on August 8th (and photographed). The Manx
Shearwater is Victoria,s first and only the third (fourth?) record
for British Columbia (but the first to be documented by photograph).
On August 9th, RPBO,s 8th record of Bank Swallow was seen, and
later that same day an immature, dark-phase Pomarine Jaeger was
seen by boat just east of Pedder Bay. An Upland Sandpiper seen
and heard on August 26th is just RPBO,s third record (and first
in seven years). On August 29th, RPBO,s first Bar-tailed Godwit
was seen (although it was also likely heard-only on August 28th),
and this is only the sixth record for the Victoria checklist area.
On August 30th, RPBO,s second record of American Golden-Plover
was observed, as was another Bank Swallow (our ninth record).
On September 3rd, a Northern Waterthrush was seen and heard during
census near Cape Calver, and a waterthrush was banded on September
6th (same bird?) for the 15th site record (this bird remained
until at least September 10th). A Franklin,s Gull on September
10th and another on September 29th are just the 5th and 6th records
for Rocky Point. On September 15th, Rocky Point,s third record
of Tennessee Warbler was recorded. Unusual in such numbers on
Vancouver Island, an impressive 1200+ Snow Goose were tallied
on September 28th. Our third and fourth records of Anna,s Hummingbird
were recorded on October 1 and 18th. A great find was a White-winged
Dove seen by two observers on October 7 this is a Rocky Point
first and only the second for Victoria. Individual Nashville Warblers
were banded on October 3 and 18th, and a "Western Palm Warbler
was observed on October 13th. On the final day of the season was
the only sighting this year for Northern Goshawk. And a good variety
of shorebirds were recorded this year as well, including Wandering
Tattler, Baird,s Sandpiper, Ruddy Turnstone, Solitary Sandpiper,
and Semipalmated Sandpiper.
Five new birds were added to the Rocky Point checklist in 2004:
Cackling Goose (thanks to a taxonomic split by the AOU and an
"old record from October 2000!), Rose-breasted Grosbeak,
Manx Shearwater, Bar-tailed Godwit, and White-winged Dove the
RPBO checklist now stands at an impressive 293 species [look for
a bar-graph to finally be published by end of 2004]. For perspective,
this total represents almost 80% of the entire Victoria/Southern
Vancouver Island checklist total!! It now seems highly probable
that Rocky Point will pass the magic 300 species mark within the
next 2-4 years.
My special hats off, congratulations, and personal thanks to:
Jukka Jantunen (Bander-in-Charge), Ann Nightingale, Pierre Geoffray,
Susanne Maidment, Mary-Ann Cain, Al Woodhouse, Brent Beach, Mike
McGrenere, Rob Gowan, Ed Pellizzon, Chris Saunders, Laurie Savard,
and Guy Monty, among a total of 40+ volunteers who helped run
the station, as well as the entire RPBO board of directors (David
Kelly President, Paul Levesque Vice-President, Tom Gillespie Treasurer,
Denise Gubersky Secretary, Michael Porter, Rod Mitchell, Rick
Schortinghuis, Marilyn Lambert, Suzanne Beauchesne, Jessica Murray,
and Katie Christie). In particular, Rick Schortinghuis worked
very hard to not only schedule volunteers, but also personally
covered many empty, time slots over the course of this season.
Finally, the site year-list stands at 202 species (and we will
likely fall just short of the high set in 2003 at 212 species).

Dear RPBO friend,
July 21st marked the start of our eleventh season of fall migration
monitoring at the Rocky Point Bird Observatory.
After 72 days of banding from July 21 to September 30, we have
banded 3345 birds of 54 species. Our average capture/day rate
has picked up dramatically in September and represents about 46
new birds banded/day. In September alone, we had six 100+ banding
days! On September 18th, we set a new one day high for our fall
banding op,s with a phenomenal 203 birds banded (plus 7 more in
the non-standard canopy net)! As a result of the steady banding,
our capture rate has also gone from well behind last year,s to
now sit 439 above last year,s pace to date! However, note also
that we have lost ~2.5 days to rain this year, whereas we lost
none last year for this same period. Already 12 species have each
established new season highs Cooper,s Hawk, Cassin,s Vireo, Hutton,s
Vireo, Red-breasted Nuthatch, House Wren, Swainson,s Thrush, Varied
Thrush, Orange-crowned Warbler, Yellow Warbler, Spotted Towhee,
White-crowned Sparrow, Golden-crowned Sparrow (and three more
are anticipated to do the same over the next couple of weeks:
Steller,s Jay, Fox Sparrow and Lincoln,s Sparrow). However, Chipping
Sparrows remain dramatically down with only 5 banded (this is
more surprising by fact that we set a season high for them last
year), and Wilson,s Warbler, Savannah Sparrow, Dark-eyed Junco,
and American Goldfinch captures are also down compared to our
last 10 seasons. Of interest, we have not banded a single swallow
this season and we normally band at least 4 to 5 of usually 2
species (last time we missed out on swallows was 1997). By far,
the main banding highlight remains the Rose-breasted Grosbeak
banded on July 18th during a volunteer banding workshop just before
start of season -- this is only Victoria's fifth record and RPBO's
first, and the bird remained in the area to at least August 4th.
In addition, two Black-headed Grosbeak were banded together on
July 27th (a second year male and a hatch year bird). A Pileated
Woodpecker banded August 28th is only the seventh ever-banded
at RPBO. During the big day on September 18th, we captured a Red-breasted
Sapsucker for our first banding record for that species. And just
our third and fourth banding record of Cooper,s Hawk were big
highlights on September 7th and September 28th.
Our nocturnal owl banding project began its third season in late
September, but has already banded 164 Northern Saw-whet Owls and
1 Barred Owl (#,,s up to October 2)! And, with assistance from
Cam Finlay, our hummingbird banding project has wound down for
its second season 27 Rufous Hummingbirds were banded at RPBO,
which is well behind last year's capture rate (and note separate
banding data set).
Among the rarities recorded so far: a Tufted Puffin was spotted
during seawatch on July 22, and individual Brown Pelicans were
recorded at Pedder Bay on July 24 and July 30 and again on September
5th west of Bentinck Island. By far, the rarest bird of the season
was the Manx Shearwater found in the afternoon by boat about 5
km east of Race Rocks on August 8th (and photographed). The Manx
Shearwater is Victoria,s first and only the third (fourth?) record
for British Columbia (but the first to be documented by photograph).
On August 9th, RPBO,s 8th record of Bank Swallow was seen, and
later that same day an immature, dark-phase Pomarine Jaeger was
seen by boat just east of Pedder Bay. An Upland Sandpiper seen
and heard on August 26th is just RPBO,s third record (and first
in seven years). On August 29th, RPBO,s first Bar-tailed Godwit
was seen (although it was also likely heard-only on August 28th),
and this is only the sixth record for the Victoria checklist area.
On August 30th, RPBO,s second record of American Golden-Plover
was observed, as was another Bank Swallow (our ninth record).
On September 3rd, a Northern Waterthrush was seen and heard during
census near Cape Calver, and a waterthrush was banded on September
6th (same bird?) for the 15th site record (this bird remained
until at least September 10th). A Franklin,s Gull on September
10th and another on September 29th are just the 5th and 6th records
for Rocky Point. On September 15th, Rocky Point,s third record
of Tennessee Warbler was recorded. Unusual in such numbers on
Vancouver Island, an impressive 1200+ Snow Goose were tallied
on September 28th. And a good variety of shorebirds have also
been tallied so far, including Wandering Tattler, Baird,s Sandpiper,
Ruddy Turnstone, Solitary Sandpiper, and Semipalmated Sandpiper.
The site year list now stands at 188 species (last year, we tallied
212 by December 31st!).
Here is a listing of birds banded from July 21 to September 30
(unofficial totals):
Cooper,s Hawk 2 (only third and fourth banding records for RPBO)

Dear RPBO friend,
July 21st marked the start of our eleventh season of fall migration
monitoring at the Rocky Point Bird Observatory.
After 42 days of banding from July 21 to August 31, we have banded
1173 birds of 45 species. Our average capture/day rate remains
slightly lower than the norm for this period with 29 new birds
banded/day, and this is behind the pace set last year for the
same period (1319birds/50 species). However, note also that we
did lose two days to rain during this period. While it is still
early to draw conclusions, already House Wren has established
a new season high at 28, as have Red-breasted Nuthatch at 14,
and Hutton,s Vireo, Brown Creeper along with Willow Flycatchers
currently each have their second highest season totals. Yellow
Warblers also appear on pace for a record year. However, Chipping
Sparrows remain dramatically down with only 5 banded (this is
more surprising by fact that we set a season high last year).
By far, the main banding highlight remains the Rose-breasted Grosbeak
banded on July 18th during a volunteer banding workshop just before
start of season -- this is only Victoria's fifth record and RPBO's
first, and the bird remained in the area to at least August 4th.
In addition, two Black-headed Grosbeak were banded together on
July 27th (a second year male and a hatch year bird). A Pileated
Woodpecker banded August 28th is only the seventh ever-banded
at RPBO. With assistance from Cam Finlay, our hummingbird banding
project continues so far, 27 Rufous Hummingbirds have been banded,
which is also behind last year's capture rate (separate banding
data set).
Among the rarities recorded so far: individual Brown Pelicans
were recorded at Pedder Bay on July 24 and July 30, a Tufted Puffin
was spotted during seawatch on July 22, and a number of good shorebirds
have been tallied, including Wandering Tattler, Baird,s Sandpiper,
Ruddy Turnstone, Solitary Sandpiper, and Semipalmated Sandpiper.
By far, the rarest bird of the season was the Manx Shearwater
found in the afternoon by boat about 5 km east of Race Rocks on
August 8th (and photographed). The Manx Shearwater is Victoria,s
first and only the third (fourth?) record for British Columbia
(but the first to be documented by photograph). On August 9th,
RPBO,s 8th record of Bank Swallow was seen, and later that same
day an immature, dark-phase Pomarine Jaeger was seen by boat just
east of Pedder Bay. An Upland Sandpiper seen and heard on August
26th is just RPBO,s third record (and first in seven years). On
August 29th, RPBO,s first Bar-tailed Godwit was seen (although
it was heard-only on August 28th) and this is only the sixth record
for the Victoria checklist area. Finally, on August 30th, RPBO,s
second record of American Golden-Plover was observed, as was another
Bank Swallow (our ninth record).
The site year list now stands at 172 species (last year, we tallied
212 by December 31st!).
Here then is a listing of birds banded from July 21 to August
31 (unofficial totals):
Downy Woodpecker 2 (only 12 have ever been banded at RPBO)
Pileated Woodpecker 1 (only 7th banding record for RPBO)

Just doing some number crunching and thought I would share it
here...
I thought some of you would find this overview of the last seven
year,s opening week,s banding data of interest. I do not intend
to do this for every bi-weekly period, but will do another one
at end of this season for a full season comparison.
Captures July 21-August 15:
1998: 480 newly banded birds of 38 species; avg. 18.5/day; 26
days banding; 0.32 birds/net-hour (1513 net-hours total, 10 nets)
1999: 614 newly banded birds of 37 species; avg. 25.6/day; 24
days banding; 0.46 birds/net-hour (1335.5 net-hours total, 10
nets)
2000: 598 newly banded birds of 43 species; avg. 24.8/day; 24
days banding; 0.38 birds/net-hour (1575.3 net-hours total, 10/13
nets)
2001: 966 newly banded birds of 39 species; avg. 40.2/day; 24
days banding; 0.64 birds/net-hour (1514.7 net-hours total, 10/13
nets)
2002: 737 newly banded birds of 40 species; avg. 28.3/day; 26
days banding; 0.38 birds/net-hour (1928.5 net-hours total, 13
nets)
2003: 797 newly banded birds of 45 species; avg. 30.6/day; 26
days banding; 0.40 birds/net-hour (1988.8 net-hours total, 13
nets)
2004: 688 newly banded birds of 39 species; avg. 27.5/day; 25
days banding; 0.36 birds/net-hour (1896.5 net-hours total, 13
nets).
(high totals in red)
1998-2004: 4880 birds banded over 175 days total, avg. of 25 days/period,
avg. of 697 new birds banded for period, avg. 40 species banded
for period, avg. 28 new birds banded/day, birds/net-hour avg.
0.42 for period total, and total net-hours of 11752 with an average
of 1679 net-hours/season for period in question. Note: total net-hours
are affected by rain, wind, presence of avian predators, BIC schedule/volunteer
coverage (esp. 1998-2000), and DND demolition exercises. For interest,
if all thirteen nets were open everyday, all day, the total net-hours
for this period would be 2028 hours (and just showcases how good
our coverage was in 2003 @ 98%!).
Data for 1994-1997 are not included at this time as net-hour data
is not readily available and coverage also significantly increased
starting in 1998 (full-time BIC).
The most important comparative figure is the birds/net-hour number
and indicates just how significant 2001 really was; how 1998 may
have indicated a poor breeding season(s) (e.g. 1997 was an El
Nino year); and how the 2002 and 2003 seasons were more or less
establishing pattern averages (?). It is also interesting to note
that total net hours have significantly increased (this is not
just due to addition of three new nets, but also weather patterns
during last three summers) for example, in 2003 net coverage increased
by about 10 net-hours/day, or 50 minutes/net/day over average
figures, but interestingly without significant increases in birds/net-hour
or even captures/day. However, in spite of setting our third highest
total net hours, this year we had our second lowest birds/net-hour
figure and only fourth highest total captures during this period.

Dear RPBO friend,
July 21st marked the start of our eleventh season of fall migration
monitoring at the Rocky Point Bird Observatory.
After 25 days of banding in July to August 15, we have banded
688 birds of 39 species, and our average capture/day rate was
slightly lower than the norm for this period with 27.5 new birds
banded/day, and this is behind the pace set last year for the
same period (737birds/45 species). Note also that we did lose
one day to rain during this period. In spite of setting our second
highest total net hours for this period, our captures were only
fourth highest and the birds/net-hour figure is the second lowest
at only 0.36 new birds/net-hour. While it is still early to draw
conclusions, already House Wren has established a new season high
at 24, Red-breasted Nuthatch has tied the high set last year,
and already 5 Hutton,s Vireo have been banded for their second
highest season total. Orange-crowned Warblers numbers were behind
in July, but they seem to have picked up dramatically over last
week. However, Chipping Sparrows are dramatically down with only
5 banded (this is more surprising by fact that we set a season
high last year), and as they are an early migrant, their migration
is mostly done so few more are likely to be caught. By far, the
main banding highlight remains the Rose-breasted Grosbeak banded
on July 18th during a volunteer banding workshop just before start
of season -- this is only Victoria's fifth record and RPBO's first
and the bird remained in the area to at least August 4th. In addition,
two Black-headed Grosbeak were banded together (a second year
male and a hatch year). Pacific-slope Flycatchers have just passed
Wilson,s Warbler for the banding lead. With assistance from Cam
Finlay, our hummingbird banding project continues so far, 24 Rufous
Hummingbirds were banded, which is also behind last year's capture
rate (separate banding data set).
Among the rarities recorded so far: individual Brown Pelicans
were recorded at Pedder Bay on July 24 and July 30, a Tufted Puffin
was spotted during seawatch on July 22, and a number of good shorebirds
have been tallied, including Wandering Tattler, Baird,s Sandpiper,
Ruddy Turnstone, Solitary Sandpiper, and Semipalmated Sandpiper.
By far, the rarest bird of the season was the Manx Shearwater
found in the afternoon by boat about 5 km east of Race Rocks on
August 8th (and photographed). The Manx Shearwater is Victoria,s
first and only the third (fourth?) record for British Columbia
(but the first to be documented by photograph). On August 9th,
RPBO,s 8th record of Bank Swallow was seen, and later that same
day an immature, dark-phase Pomarine Jaeger was seen by boat just
east of Pedder Bay. The site year list now stands at 145 species
(last year, we tallied 212 by December 31st!).
Here then is a listing of birds banded from July 21 to August
15 (unofficial totals):
Downy Woodpecker 1
Willow Flycatcher 21
Hammond's Flycatcher 5
1. Pacific-slope Flycatcher 105

Dear RPBO friend,
July 21st marked the start of our eleventh season of fall migration
monitoring at the Rocky Point Bird Observatory.
We are all very pleased to once again have the very experienced
Jukka Jantunen as our Bander-in-Charge this year. After 11 days
of banding in July, we have banded 335 birds of 35 species, and
our average capture/day rate was higher than the norm for this
period (30.5 new birds banded/day vs. long term average of 24),
but this is slightly behind the pace set last year for the same
period. While it is still early to draw conclusions, already Pacific-slope
Flycatcher, Warbling Vireo, Chestnut-backed Chickadee, Brown Creeper,
Bewick's Wren, House Wren, MacGillivray's Warbler, and Wilson's
Warbler each appear on their way to high years. Of potential concern,
are the low numbers of Orange-crowned Warblers banded so far (in
general, few also seem present around the station). By far, the
main banding highlight remains the Rose-breasted Grosbeak banded
on July 18th during a volunteer banding workshop just before start
of season -- this is only Victoria's fifth record and RPBO's first.
In addition, two Black-headed Grosbeak were banded together (a
second year male and a hatch year). With assistance from Cam Finlay,
our hummingbird banding project continues -- in July, only 7 Rufous
Hummingbirds were banded, which is well behind last year's capture
rate (separate banding data set).
Among the rarities recorded so far: individual Brown Pelicans
were recorded at Pedder Bay on July 24 and July 30, a Tufted Puffin
was spotted during seawatch on July 22, and a number of good shorebirds
have been tallied, including Ruddy Turnstone, Solitary Sandpiper,
and Semipalmated Sandpiper. The site year list now stands at 133
species (last year, we tallied 212 by December 31st!).
Here then is a listing of birds banded from July 21 to July 31.
Downy Woodpecker 1
Willow Flycatcher 2

Just a few first week highlights:
July 18 -- during a volunteer banding workshop, Ann Nightingale
and Jessica Murray banded Rocky Point's first Rose-breasted Grosbeak
(only fifth record for Victoria checklist as well). It remained
to at least July 23. See our photos section for a great shot!
July 22 - a Tufted Puffin was seen by BIC Jukka Jantunen offshore
during seawatch.
July 24 - during census, yours truly recorded an immature Brown
Pelican at Pedder Bay-William Head.
July 25 - a Solitary Sandpiper and a Ruddy Turnstone were recorded.
With the grosbeak and the recent split by the American Ornithologists'
Union (AOU) of Cackling Goose from Canada Goose (I photographed
a pair of Cackling's in fall of 2001 near Building 100), the latest
RPBO Checklist stands at a whopping 289 species!
As in previous years, I will also begin posting bi-monthly banding
totals and sightings details after July 31st.
Here's to another great season at the point!

Thanks to the hard work of several RPBO people the 2004 banding
workshop was a resounding success!
Here is a write up by Paul Levesque, the one from whose brain
sprung the seed, followed by a note from RPBO's President, David
Kelly.
Paul's write up:
Hi everyone. I thought I would send out a note about the 2004
RPBO Bird Banding Workshop.
Well, it looks like we put on the best one yet! On Friday, I gave
a talk on banding ethics, bird safety and a few other topics that
were not covered last year. In the evening, Jukka gave his now
famous talk on age classes and moult. On Saturday morning, we
opened four mist nets and banded eleven birds with two retraps
(mostly Juncos, some Chickadees and at least one Bushtit.) The
weather was touch and go with short drizzly periods, but we made
do. After lunch we were in the classroom working with the frozen
birds. This year I asked Ann to set up a hummingbird banding "station"
and the workshop participants learned how we make hummingbird
bands; each student used the shaping tool and then put a band
on a frozen Rufus Hummingbird. The humming bird banding was very
popular. Tracy Anderson from Wild Arc (the Wild Animal Rehabilitation
Centre in Metchosin) was taking the workshop. In the late
afternoon, she approached me and said that Wild Arc had a Merlin
that was ready to be released which could be delivered if we were
interested in banding it. Naturally, I jumped at the opportunity
and the workshop participants were treated to a Merlin getting
banded and released. Thanks Tracy.
The pub at Royal Roads was closed Saturday night, so the social
session was cancelled. I am very sorry if anyone missed
the e-mail I sent about this Friday night and ended up at the
pub.
On Sunday morning, we opened the nets at 7:00 am and started banding.
From the get go we were getting good numbers, Song Sparrows, Juncos,
Robins, and Chickadees. Participants were getting a fair bit of
handling in and I was relieved because we hadn't banded that many
birds on Saturday. (One of the biggest complaints last year was
that people had hoped to do more bird handling.) So things were
going well.
Back in mid January, Ed and I set up a large seed feeder and a
suet feeder in one of the net lanes. We kept the feeders topped
up and about two weeks ago I added an extra suet feeder. This
bait seemed to pay off because we ended up getting slammed with
birds. All of the participants were able to band a bird and have
a crack at extraction! We also banded a Ruby Crowned Kinglet and
to top it off we then caught a male and a female Hairy Woodpeckers!
We ended up banding 23 birds, had 3 retraps and released about
ten birds unbanded. Good times.
After the banding session we went back to the classroom for Ann's
demonstration on the two hummingbird traps and Jukka demonstrated
his walk in trap and his bow trap; we then stopped for lunch.
After the break, we worked on aging the frozen birds and around
3:30 p.m. called the workshop to a close.
How did we manage to pull this all off? Well, RPBOers came together
as a team:
Laurie spent a lot of time answering e-mail and telephone enquires
from people interested in the workshop and prepared a worksheet
for participants on aging for the Friday night session.
Denise made up receipts and mailed out all of the banding manuals
to the workshop participants as their cheques arrived at my place.
Marilyn picked up the coffee, tea, milk, juice, fruit, cups etc.
and lent us her 30 cup coffee maker. Marilyn your tupper ware
and coffee maker is at my place.
David A. also picked up food, lent equipment and was able to spend
time on Friday, Saturday and Sunday helping out.
Ann Nightigale, where to start? Ann once again was our liaison
person with Royal Roads and managed to get classrooms booked and
dorm rooms made availible. Ann picked up participants from the
ferry on Friday, help set up the Cedar room and the Nixon room,
arrived first thing in the morning to open the Cedar room and
put the coffee on. She put together a power point presentation
on age classes for Jukka. Ann also taught all of the humming bird
banding. Ann also did a number of other important tasks and her
contributions can't be over stated.
Rick, Ed and Katie. Both Rick and Ed were busy this past weekend.
They set up all the nets, topped up the feeders, moved the freezer
from my place to Royal Roads, set up a tarp and table for the
banding shack, helped to teach and extracted birds. Rick, Ed and
Katie took down all of the nets and packed up the banding station.
Katie also lent us equipment including her banding kit so that
we would have extra tools during the lab sessions.
Jessica Murray, (our newest board member) spent Saturday and Sunday
teaching. On Saturday, she ran the "band the frozen bird"
station and patiently taught 18 people one after another how to
band the same Swainson's Thrush.
Tom and Dave K also stopped in over the weekend to help out and
to see how things were going.
I would like to thank all of you for your help and to let you
know that you all did a fantastic job at making this the best
workshop yet. I am very pleased.
Paul Levesque.
A word from RPBO's President:
You will all have seen Paul's note on the banding workshop last
weekend. I want to express my personal appreciation to all of
you who assisted in making the weekend such a success. I particularly
want to thank Paul for his tireless effort in organizing and leading
the workshop. The workshop demonstrates that RPBO is a capable
and professional organization; it enhances our reputation; and
it produces volunteers. It is a first class effort, and Paul deserves
credit for initiating and leading the event. Thanks Paul, and
thanks again to all who assisted. Good work.
