Week 12: Time for Thanksgiving Turkey (Vultures)

WEEK 12 – October 5th - October 11th

Pedder Bay

At our Pedder site this week we banded 203 new birds, a marked decline from last week as migration begins to slow down for the fall. The main species captured include Pacific Wrens, Ruby-crowned Kinglets and Hermit Thrushes, as well as Fox, Song, and Golden-crowned Sparrows. These species are found on southern Vancouver Island throughout the winter, so we are likely starting to catch birds that are winter residents here!

One morning we were lucky to catch two Sharp-shinned Hawks, a young male and female! These raptors are often seen around both stations but are rarely captured, so it is always a nice surprise when we get to see them up close.

Rocky Point

Banding was once again heavily interrupted by poor weather and the presence of American Mink, but it was still a pleasant week of migration monitoring! With the nets closed we focused mainly on observations, seeing quite a few species moving in good numbers along with some rarities and less common migrants.

Massive numbers of Brandt’s Cormorants and Common Murres were seen in the water surrounding Bentinck Island and Race Rocks, with daily estimated totals numbering in the thousands! The species diversity of seabirds observed wasn’t particularly high, but it was great to watch large groups of birds gorging themselves on small fish alongside Humpback Whales and Orcas in “bait balls”.

Turkey Vultures were still moving in large kettles this week, but it appears the bulk of the other migrating raptors have moved on. We also received the information for a tagged Turkey Vulture seen on October 3rd, and found out it was originally banded as a one-year-old bird (meaning it is now 12 years old!) in the summer of 2015 in Grayland, Washington. It has been reported 14 times since then, including another sighting at Rocky in September 2024 by then Bander-in-Charge David Bell!

Other notable birds observed this week include a Western Palm Warbler, multiple Western Meadowlarks, Sandhill Cranes, a Franklin's Gull, and most excitingly an adult Lesser Black-backed Gull spotted by Cathy Reader and identified by Adam Ross! This was a first for Rocky Point, and the 302nd bird species reported from the site.

We did manage to catch a small number of birds in our limited net hours this week, including a recaptured female Spotted Towhee that was banded as an adult on October 14th, 2024 (at least 3 years old). It is always nice to recapture birds year to year, welcoming them back to the site after they likely spent the breeding season elsewhere.

WEEK 11 – September 28^th- October 04^th

Pedder Bay

No doubt the weather has changed to cooler and wetter this week, but we are still greeted by familiar calls on arriving at the station. It is our fortune that migration monitoring starts early, so we can hear Great Horned and Northern-Pygmy Owls calling. At this time of year Song Sparrows are often next, eager to begin the morning chorus. Pacific Wrens, Varied Thrushes, Fox Sparrows and Golden-crowned Sparrows readily join in as the day breaks, and by then we are likely banding our first birds of the day.

This week banding at Pedder Bay station has far surpassed Rocky Point (details below), with 329 birds banded. Primarily Fox Sparrows (56), Ruby-crowned Kinglets (51), Hermit Thrush (39), Song Sparrow (32) and Oregon Junco (29) were banded. Some Swainson’s Thrushes are still present (16 banded); and Golden-crowned Sparrows (28 banded) now outnumber Puget Sound White-crowned Sparrows in the surrounding thickets as well as the parking lot. A few other notable species banded this week were a Wilson’s Warbler and a Northern Saw-whet Owl.

Our busiest banding days are likely behind us, but visitors continue to drop in to visit the station. We have now welcomed over 500 visitors at Pedder Bay during fall migration monitoring, and many more have visited owl banding in the evenings. It’s always enjoyable to share some of our knowledge with the public.

Rocky Point

At Rocky Point this week banding was limited (110 birds banded) due to a few proceedings. On September 29^th both Pedder Bay and Rocky Point were closed due to rain. On October 2^nd a controlled prescribed burn was undertaken on the DND site by Natural Resources Canada. Hopefully one of the outcomes of these annual burns is to restore Garry Oak ecosystems and provide habitat for species at risk. Only a few hours of banding were conducted this morning before the banding crew was required to leave the area. 

The following two days (October 3^rd and 4^th) banding was exempt due to the presence of American mink. However, we continued to conduct census, and the banders and volunteers shifted their effort to documenting as much bird incidence as possible. Some of the notable observations were – Greater-white fronted Goose, Brant, Gadwall, Pectoral Sandpiper, and a Common Grackle. Yes, a Common Grackle was seen perched on the cattails adjacent to the front nets! This blackbird’s population increased and spread in Eastern North America in response to increasing farmland and became quite fond of sprouting corn. However, their current population is in decline. 

Brandt’s Cormorant (2450), Common Murre (2300), Turkey Vultures (1600), Pine Siskin (250) and Yellow-rumped Warblers (150) have been seen in high numbers this week. A few warbler species still linger in low numbers, with 1-2 individuals recorded per day, these include Orange-crowned Warbler, Northern Yellow Warbler, Common Yellowthroat, and a seldomly seen Palm Warbler. 

With just under 2 weeks of fall migration monitoring remaining, we will be keeping our eyes to the skies to marvel at (and count!) the raptors, geese, as well as passerines as they continue to head south.

Week 10: The Kinglets Are Among us

A Ruby-crowned Kinglet - The Most Banded Bird At The Rocky Station This Week (Gaelin Armstrong)

Week 10 (September 21st – 27th) has come and gone, and Fall has arrived at our stations, and so have Kinglets!

Rocky Point 

Our Rocky Point station caught 382 new birds banded and 46 recaptured birds this week. The most caught bird this week was the Ruby-crowned Kinglet with 62 individuals. The second most banded bird was the Yellow-rumped Warbler with 48 total banded, including unknown subspecies/hybrid with 36, Myrtle with 12, and Audubon's with 12. The third most caught bird this week was the Golden-crowned Sparrow at 40, followed by the Pacific Wren at fourth with 25 banded, and then tied for fifth were the Fox Sparrow and Spotted Towhee, both with 20 banded.

Pedder Bay 

The Pedder Bay banding station caught 436 new birds banded and 106 recaptured birds this week. With the top species being banded this week with Fox Sparrow with 75, followed by Hermit Thrush with 69, Oregon Junco with 53, Golden-crowned Sparrow with 46, and both Ruby-crowned Kinglet and Golden-crowned Kinglet tied for fifth most banded bird this week with 30 of each caught.

Observational highlights this week included massive kettles with a high count one day of 950 Turkey Vultures seen, mixed in with Broad-winged Hawks and Red-tailed Hawks. Flocks of Black-tailed Pigeons have been seeing flying over the station towards Bentinck Island, and a pair of Greater Yellowlegs were hanging out and foraging along the shore in the front for most of the week. Flocks of Greater White-fronted Geese, Canada Geese, and Cackling Geese were seen flying in V's over the station. Massive numbers of Common Murres were observed, and the Red-footed Booby was seen offshore of Rocky Point in with a bait ball feeding frenzy.

Week 9: Warblers and Sparrows and Jays Oh My!

 Week 9 (September 14th-20th) of Rocky Point Bird Observatory’s migration monitoring season has come to a close, bringing us into the final month of fall songbird banding. Even with the finish line creeping closer, migration remains in full swing.

In total 484 birds were banded at Rocky Point with an additional 353 at Pedder Bay, almost identical numbers to last week. While the numbers didn’t offer a change of pace, the mix of species we caught changed in several notable ways. Last week’s arrival of our first Yellow-rumped Warblers led nicely into a larger push of the species at both stations over the last several days. The “Audubon’s” subspecies that we catch was joined by the eastern and northern-breeding “Myrtle” subspecies and we caught more than four times as many of this hardy species this week as we did the week prior. While many of our other warbler species are dwindling or absent by this time we are still seeing a few Common Yellowthroat and Northern Yellow Warbler work their way south in addition to our second Townsend’s Warbler of the season at Pedder Bay.

Fox and Golden-crowned Sparrows were among our most caught birds this week with 83 and 99 individuals, respectively, having been banded between the two sites. Swamp Sparrow was a new addition this week meaning we have now banded all three species in the genus Melospiza, which also includes Song Sparrow and Lincoln’s Sparrow.

Other banding highlights from this week included our first, and so far only, Cassin’s Vireo of the season, several White-throated Sparrow, and increased numbers of Steller’s Jay, Pacific Wren, and both Ruby and Golden-crowned Kinglets.

Week 8: Familiar Faces

    As we enter the peak of fall migration some long-awaited migrant and winter species have begun to arrive in large numbers, both in our nets and around the stations...

    It is officially Sparrow September! This week we welcomed back a wave of Oregon Juncos, Fox Sparrows, Golden-crowned Sparrows, Gambel's White-crowned Sparrows, White-throated Sparrows, Lincoln's Sparrows, Song Sparrows and Savannah Sparrows.

    Some other fun species arriving include Hermit Thrushes, Steller's Jays, and Varied Thrushes! Thus far the Steller's Jays and Varied Thrushes haven't been caught in large numbers, but we were happy to catch 4 STJA and 1 VATH this week.

    We were also lucky enough to catch another Northern Pygmy-Owl at Rocky, making this the first year since 2018 (2 banded at Pedder) where multiple have been banded in a season.

    Another familiar face this week was Wilson's Warbler #2950-06806, the 6+ year old female (banded as an AHY in 2021) that was mentioned in the blog for week 2. She has almost fully completed her prebasic molt for the fall, and is now looking much more put-together than she did in August!

    In terms of observations we've been treated to some amazing raptor movement in the skies with large groups of hawks (including multiple Broad-winged Hawks), falcons and vultures. On the ocean both seabirds and marine mammals have been quite prevalent, with Humpback Whales, Orcas, thousands of birds (mainly gulls, alcids, loons and cormorants) taking advantage of the Pacific herring bait balls forming in the straight. We've also had a number of reptile and amphibian visitors, including Northwestern and Western Terrestrial Garter Snakes, Red-legged Frogs, and Pacific Chorus Frogs.

Week 7 - Should I stay or should I go

Many of the birds observed at the banding stations this week are familiar to us - Puget Sound White-crowned Sparrow, Western and Willow Flycatchers, Swainson’s Thrush, Wilson’s and Orange-crowned Warblers. And most of them have built up significant fat reserves, suggesting they will be migrating very soon. But this first week of September has also brought us species that we anxiously await; Hermit Thrush, Fox Sparrow, Golden Crowned-sparrow, Ruby-crowned Kinglet and Steller’s Jay have been added to our list of species banded.

Their arrival signals that fall migration is gaining momentum and birds will be moving through (or above!) the area in high numbers on some nights. While most birds will continue further south to their respective overwintering sites, those that do stop here, whether briefly or for the winter, are warmly welcomed.

Pedder Bay

Our most banded species at Pedder Bay this week were Puget Sound White-crowned Sparrow (36), Swainson’s Thrush (35) Lincoln’s Sparrow (28), Spotted Towhee (16) and Purple Finch (15).

A Clay-colored Sparrow was banded on September 1^st. It’s subtle plumage appears well suited for camouflage in the dry grasses of the Great Plains where it is numerous. The individual was caught in net #12, adjacent to the Pedder Bay estuary.

A Townsend’s Warbler (HY) was also banded at Pedder Bay this week.

Rocky Point

At Rocky Point we continue to band high numbers of Puget Sound White-crowned Sparrow (44), Orange-crowned Warbler (30), Swainson’s Thrush (26) and Westen Flycatcher (25). We saw a significant increase in Northern Yellow Warbler (74), Lincoln’s Sparrow (46) and Savannah Sparrow (29) in the nets, and on our daily observations.

Our banding highlight for the week was our first Steller’s Jay of the season. They appear to have returned in high numbers with over 40 individuals recorded on a single day. Also banded this week was a Red Winged Blackbird (HY-M) and a Sharp-shinned Hawk. 

Notable observations at the station were Wilson’s Snipe, Pomarine Jaeger, Long-tailed Jaeger, Sabine’s Gull, Red-necked Phalarope, Northern Waterthrush and Gadwall. Over 300 Band-tailed pigeons were counted on September 6^th, and hundreds of Vaux’s Swifts have been observed migrating over both stations this week.

We expect both birds observed and banded to continue to increase this month at our migration monitoring stations. Thanks to all the volunteers for their efforts contributing to daily observations, census and banding operations at Rocky Point Bird Observatory, we couldn’t do it without you!
