Week 6: Who is Viosca?

Answer: the person who a subspecies of this week's banding highlight is named after! Read on to find out more (or just check out the header photo).

Despite some seemingly slow days, and having multiple nets closed at both stations due to wind on several days this week, both stations had above-average catches during Week 6. Rocky had 260 new bands compared to an average of 234, while Pedder managed 220 new bands, compared to an average of 200. Along with these higher-than-usual numbers came some new captures for the season; both the weather and birds felt distinctly like fall! Newly banded species for the season at Rocky were Barred Owl, Golden-crowned and Fox sparrows, Hermit Thrush, Townsend’s Warbler, and Hammond’s Flycatcher. New at PB were Steller's Jay and Fox Sparrow. Our top captures for the week were Swainson's Thrush, Pacific-slope Flycatcher, and White-crowned Sparrow, while Lincoln's Sparrow and both Yellow and Wilson's warblers had good pushes. Some visitors at Pedder on the 26th were treated to a whole flock of Western Tanagers in the nets as well! At the end of Week 6, Rocky remains above-average in terms of birds banded, while Pedder is still well below average (although it is catching up quickly!).

Rocky dominated the banding highlights this week, with a first RPBO banding record of Band-tailed Pigeon (an adult male!) in net 5 on the 30th. We often see this species flying high overhead, and there have been a few suspicious feather piles indicating that they sometimes hit the nets, but their large size means they would get out easily. Luckily Liam was quick and managed to get his hands on it before it had a chance to escape! Band-tailed Pigeon has a subspecies originally described as a separate species: Viosca's Pigeon (hence the blog title) - it resides in southern Baja California. The other highlights were a Clay-colored Sparrow banded on the 25th (5th banding record for RPBO) and a Western Wood-Pewee banded on the 29th (12th banding record for RPBO). While not a rarity, one other highlight of the week was breaking the season record for Anna's Hummingbird at both stations! Our totals of 60 at Pedder and seven at Rocky beat out the previous highs of 55 and six, respectively.

Observation highlights at Rocky included a Least Flycatcher on the 25th, a Pomarine Jaeger on the 26th, a Brown Pelican and a Cassin’s Auklet on the 27th, and several flocks of Short-tailed Shearwaters on the 30th. New species for the season there included Northern Pintail, Harlequin Duck, Horned Grebe, and Tree Swallow in addition to the newly banded species. Pedder Bay was quieter in terms of highlight species, but new for the season there included Rock Pigeon, Common Loon, Pied-billed Grebe (third station record during migration), and Semipalmated Sandpiper (fourth station record).

Humpback Whales seem to be appearing in greater numbers recently at Rocky, and both stations had good numbers of Black Saddlebags (dragonfly) around this week. This species seems to be increasing substantially in recent years on southern Vancouver Island. The mink family is still around at Rocky – thankfully they have been staying away from the nets. An Eastern Cottontail had a close call with one on the 31st though, as the mink chased it across the road toward me.

In other news, we regretfully said good-bye to our interns at the end of this week. They are both headed back to school in a few days - we will certainly miss having them full-time at the stations. Luckily for us, they are both at UVic and will be volunteering in their spare time! Thanks for all your hard work these last six weeks and good luck with your studies, Liam and Rebecca!

Week 5: At L(e)ast, a Banding Tick!

An absolutely adoooorable Least Flycatcher! (David Bell)

    The end of August is when better turnover of migrating songbirds occurs, a time when we start to see and catch more! We expect this uptick in activity as we approach the fall months and it’s always pleasant to see when the passerines start flowing! 

    Numbers are beginning to increase for us, and fall is definitely in the air. Both of our stations are catching more birds each day compared to previous weeks, and daily species + individual totals are on the rise. Total number of new birds banded this week at Rocky Point was 204 (vs 183 the week before), and at Pedder Bay we banded 206 new birds (vs 110 the week before).

    Vireo and Flycatcher counts are gradually on the climb, and as for Warbler numbers, they are skyrocketing! The presence of Yellow Warblers is very evident right now. This week we’ve been recording anywhere from 20 individuals, all the way up to 75 individuals at both stations on daily estimated totals. Compare this to last week when we were only seeing ~3-10 individuals. Yellow Warblers are not the only Parulidae increasing at both sites; daily counts of individual Orange-crowned Warblers, Townsend’s Warblers, and (my personal favourite) Black-throated Grey Warblers are steadily rising too as fall progresses. We caught our first Townsend’s Warblers of the season (two) at Pedder Bay this week! 

What a gorgeous Townsend's Warbler! - 1 of 2 caught (Samuelle SP)

   With this increase of passerine activity comes the prospect of finding a rare songbird or two. Usually these rare songbirds are encountered around the stations (either at Rocky Point or Pedder Bay), but occasionally we get lucky and find a rarity in one of our mist nets. 

    This week at our Rocky Point station we got our first taste of interior-rarity-action when we banded a Hatch-Year Least Flycatcher! This tiny, subtly plumaged, Empidonax species is a common summer breeder across the vast majority of Canada and parts of the United States, but is rarely found along the western edge of BC. On August 23rd, when we caught it, we actually observed two other individuals (so at L E A S T three individuals were around the station that day). Two were hanging around the nets and eventually one ended up hawking itself right into the upper section of net 8, giving RPBO it’s 4th (ever!) banding record of this species. This was a long awaited banding tick for one of our interns (Liam), who up until then, had not gotten to band any new species. A well deserving species to get for his first banding tick of the season!

    Another species we caught that's not quite as rare as the Least Flycatcher but still equally as thrilling to band, was a Northern Waterthrush! We caught this bird at our Pedder Bay station and it represents only the 6th banding record for Pedder Bay (total between both sites is 29).

    Also at the Rocky Point station, we caught another exciting species, a Marsh Wren! Like the Northern Waterthrush, we typically catch one a year.

Other birds of interest we have banded this week between the two stations included: 

A Black-throated Grey Warbler (RP), 

Our second Cooper’s Hawk of the season (PB), 

Two Hammond’s Flycatchers (PB), 

Another Barn Swallow was caught (PB), 

Two Red-breasted Sapsuckers (RP)

Nine Western Tanagers (PB)

Week 4: Return of the King(fisher)

So…. Week 4! 

     Although mid August is a relatively slow time for migration, we’ve had an awesome week! It started off with a beautiful hatch year female Belted Kingfisher on Thursday August 12th at Pedder, a very long-awaited banding tick for me. This was our third Belted Kingfisher for the year!

     Last weekend we had our first notable wildfire smoke for the season, which is unfortunately becoming a yearly (or multiple times yearly) occurrence. Visibility was fairly poor at times, and led to some interesting sunrises that are becoming all too familiar.

     As fall migration slowly starts up, we’ve also been catching a couple interesting subspecies that are starting to pass through! We had our first of the year "Grey-headed" Orange-crowned Warbler and "Olive-backed" Swainson’s Thrush which don’t usually spend the breeding season here, so it’s a sign that birds are moving south.

     Our awesome Bander in Charge Dave was rewarded on Tuesday August 17th with a hilarious young Pileated Woodpecker, the second we’ve caught this year and a much-wanted banding tick for him! This is a bird that many banders dream of getting the chance to band, so we’ve been extremely lucky this year to catch two.

     One part of banding that I absolutely love is getting recaptures from previous years. I’d like to give a little shoutout to this gorgeous adult "Puget Sound" White-crowned Sparrow, who was banded as an After Hatch Year in 2017! That means this bird at least 5 years old! Good luck on your migration this year little PSWS💗
