13-18 October
American (Buff-bellied) Pipit, Rocky Point, 17 October 2025
(David M Bell). The Austin Powers fans among you may appreciate this week’s
blog title.
Well, that’s a wrap! The week started well at both stations.
It was evident mid-October was upon us as a drop in temperature was felt, with
hats and gloves being cracked out while shorts and t-shirts were folded away
for the foreseeable. Monday saw 90 birds banded at Rocky Point, including 23
Ruby-crowned Kinglets and 21 Pacific Wrens. Two hatch year Gambel’s
White-crowned Sparrows also visited the nets, as did a recapture Golden-crowned
Sparrow who had been banded in 2021. Pedder Bay boasted 70 birds banded on the
same day.

Tuesday was off to a Rocky-er start, with a Roosevelt Elk
charging through one of the nets. It was swiftly replaced, and 40 birds were
banded there, while a first year Franklin’s Gull was observed, which would go
on to linger through the week. The Bay of Pedder produced 31 new birds,
including a stunning male Anna’s Hummingbird, a late Wilson’s Warbler and a
Pacific Wren recaptured from last year.

greyish-fringed. This was mirrored in the primary coverts. (Max Hellicar)
Wednesday saw 37 birds banded at Rocky Point and 26 at Pedder Bay. Rocky’s haul included a Steller’s Jay; the 9th individual to be banded there this season.

Thursday morning was a chilly one but that didn’t stop
RPBO’s first-ever American Pipit (to be banded) from going into the nets. Separate
to our standardised operations, this bird was captured as part of an attempt in
a different area, in order to assess the feasibility of instigating a long-term
project on the species. Data from the Bird Banding Lab (https://www.pwrc.usgs.gov/BBL/Bander_Portal/login/bbl_data_request_summary.php)
show only 37 prior individuals to have been banded in British Columbia (1960-2025),
so it is a species we really could do with learning more about here! American
Pipits are a long-distance migrant which move from breeding grounds as far
north as the Arctic circle to wintering grounds as far south as central
America. They occupy a continuous distribution across North America, breeding across
the north and wintering across the south. There is a massive gap across the centre
of the continent which they only use to pass through during migration. Banding pipits can
help unravel the picture of where migrating pipits, such as those passing
through Rocky Point, breed and spend their winters. Two Hutton’s Vireos were
also trapped at Rocky Point on Thursday; one new hatch year and a recapture
from last year. Pedder Bay banded 26, including another Anna’s Hummingbird.

Friday was another nice day at Rocky Point. Banding totalled
28 birds and included a juvenile male Sharp-shinned Hawk, the third Swamp
Sparrow of the season and RPBO’s second-ever banding record of American Pipit
(both hatch years). The lingering Franklin’s Gull remained, and good views were
had by all! 6 Black Bears were sighted on the way out of the site; a fitting end
to the penultimate day of the season. On the theme of large mammals, Roosevelt
Elk have been reliably seen through the week and are always a welcome site
(apart from in the net lanes!). 20 birds were banded at Pedder, where a
Red-breasted Sapsucker was recaptured.

Saturday morning produced a third-ever banding record for Rocky Point in the form of a Tennessee Warbler. Previous records were in 2006 and 2019. Meanwhile at Pedder Bay, a juvenile female Sharp-shinned Hawk was captured. The end of the season was determined by rain at the latter site, with nets closed 20 minutes early as a result, ending the day on a total of 32 birds banded. Rocky Point fared mildly better, with 40 new birds captured, including a Marsh Wren. A Townsend’s Solitaire was a good observation for those on site. The last bird of the season at Pedder Bay was an adult female Ruby-crowned Kinglet, while Rocky Point’s final bird was a hatch year Pacific Wren.

This week’s top five species at Rocky Point were
Ruby-crowned Kinglet (88), Pacific Wren (43), Golden-crowned Kinglet (31) and
Sparrow (26), followed by Spotted Towhee (19). At Pedder Bay, the top five for
the week were Ruby-crowned Kinglet (49), Hermit Thrush (30), Pacific Wren (22),
Fox and Golden-crowned Sparrows (20 each).

That’s the breakdown of the week done, now let’s take a
broader look at the season as a whole…
Rocky Point ended the season with a total of 4442 birds
banded, comprising 72 species. This constitutes the second-best-ever autumn
(since standardisation in 2000), overtaking 2019’s total of 4378 in the last
few days and just pipping it to the post. 2005 still holds the title, however,
with 4619 new birds. This year is well above the annual average (2000-2024) of
3296 birds banded. Totals per year fluctuate greatly, with the worst-ever year
for totals being 2001 (2596 birds banded), and this is often driven by good or
bad years for a select few, or even a single, species. Such fluctuations
highlight the importance of long-term monitoring for the recording of
population trends.
The banding totals board after the season finale at Rocky Point
In 2025, there were 886 records of recaptured birds at Rocky
Point, involving 34 species and constituting a mix of those banded during this
season (many of whom were repeat offenders) and those from previous years. Our primary
goal is monitoring migration, many aspects of which can be achieved purely by
comparing numbers of new birds per year to monitor population trends. However,
recaptures build a picture of site fidelity across different years and within
the same season, providing valuable results with implications for conservation.
While we recapture a number of individuals of our resident species, adding to
the picture of the importance of our monitoring sites to them, we have also
recaptured a number of migrant individuals recently who were banded in previous
years, and this multi-season site fidelity shows the importance of the area in
their migratory flyway.

During our standardised migration monitoring (21 July to 18
October), Rocky Point saw its best ever year for White-crowned Sparrow (537
individuals banded), Spotted Towhee (438), American Goldfinch (260),
Black-headed Grosbeak (9), Olive-sided Flycatcher (6), Palm Warbler (2) and
Brewer’s Sparrow (1 – a first for Rocky Point so an automatic record year).
That was a lot of White-crowned Sparrows and Spotted Towhees! Joint record
years were seen for Clay-coloured Sparrow (3), Cooper’s Hawk (2), Ovenbird (1)
and Tennessee Warbler (1).
Over at Pedder Bay, the season ended with 2864 birds banded,
comprising 61 species. 714 recapture records were processed, involving 36
species. This marks RPBO’s fourth-worst year at Pedder Bay (or eleventh-best,
depending on whether your glass is half empty or half full), falling below the
2012-2024 average of 3147 birds per season.

The bulk five species banded at Rocky Point this season were
White-crowned Sparrow (537), Spotted Towhee (438), American Goldfinch (260),
Wilson’s Warbler (242) and Western Flycatcher (226).
The bulk five species banded this season at Pedder Bay were
Fox Sparrow (246), White-crowned Sparrow (222), Swainson’s Thrush (219), Hermit

As ever, sincere thanks go out to our fantastic crew of
staff and volunteers who made this season possible! Many volunteers have given
large sums of their own time to ensure the continued running of operations at
RPBO and this never goes unnoticed. If you're interested in checking us out, do head over to rpbo.org. We hope you’ve enjoyed these weekly blogs.
Stay tuned for next season’s!
