RBA: SHORT-TAILED ALBATROSS off Tofino - June 1st

At 12:30pm on June 1-2017, Lev Frid spotted an immature Short-tailed Albatross during a pelagic run from the Whale Centre out of Tofino. The bird was 35 nautical miles SSW of Tofino in a flock of Black-footed Alabatrosses. Captain John Forde was able to obtain a photo of the bird, as it sat on the water. Multiple observers, who were part of an Eagle-Eye birding tour, were able to observe the bird until 1:15pm when it flew by the boat and disappeared.

"UBC zoologists have documented the first record of a House Swift in the Americas—and begun to unravel the mystery of how the tiny bird got from its south-east Asia breeding grounds to Ladner, BC.“These birds are amazing fliers and can stay airborne for months at a time, but there wouldn’t have been enough insect prey to sustain him properly over the mid-Pacific. The mystery is what sent him so far off course.”

The bird’s well preserved but near-emaciated carcass was discovered in May 2012 near the Deltaport container terminal, just 40 metres from the Pacific Ocean.“Like some marathon runners, I think this fellow finally saw land and just crashed, exhausted, at the finish line,” says Ildiko Szabo, a curator at the Beaty Biodiversity Museum and forensic ornithologist who led the identification of the specimen.
“These birds are amazing fliers and can stay airborne for months at a time, but there wouldn’t have been enough insect prey to sustain him properly over the mid-Pacific. The mystery is what sent him so far off course.”

In a paper published today in The Wilson Journal of Ornithology, Szabo and co-authors, including UBC researcher Darren Irwin, propose that either a storm set the bird off course, or even more likely, his internal navigation ’compass’ malfunctioned.“Our initial reaction was skepticism that this would be such an unusual species,” says Irwin, who studies how new bird species arise. “But by combining a review of the bird’s characteristics with DNA testing, we were able to confirm that this was indeed a House Swift from Asia, making this an exceptional case of vagrancy.”

The prospect of the bird hitching a ride by ship or plane is unlikely, say the authors. Swifts don’t typically roost on ships, and the bird would have needed to be airborne to feed over at least portions of the journey. The near perfect condition of the swift’s feathers also indicates it wasn’t trapped in a plane’s wheel well.There were no indications of trauma, parasites, disease or oiling. But the 13-centimetre swift was very underweight, and had entirely depleted its fat stores.

House swifts (Apus nipalensis) range west to Bhutan, and as far east as Honshu Island, Japan. And until now, this species had never been found in the Americas. Other swift species from Asia have reached the Alaskan islands, and European swifts have occasionally successfully completed Atlantic crossings.The discovery is likely to excite birdwatchers and cause a cascade of bird list updates—the species needs to be added to the Greater Vancouver Area, British Columbia, Canadian and American Birders Association Area bird lists.

The specimen is currently on display at the Beaty Biodiversity Museum, Vancouver’s natural history museum.

Not only is this the first record of this species in the Americas, it is also of course, the first ABA and BC record.

RBA: 2 SHORT-TAILED ALBATROSSES off Tofino - MAY 13th

At 4:20pm on May 13-2017, while working on the FV Nordic Pearl, Lindsay Dealy found and photographed two immature Short-tailed albatross. She had the birds in view for 15 mins.

An exact GPS location of where the birds were was 48°50'22.0"N 126°18'56.6"W and is pinned on a map HERE. The birds were in a flock of Black-footed Albatrosses that were following the vessel.

RBA: HERMIT WARBLER in Victoria - May 15-16th

At 10:15 am on May 15-2017, Daniel Donnecke found and photographed an adult male Hermit Warbler at Mount Douglas Park. The bird was singing and was seen on Glendenning Trail. This is a steep trail that heads straight down into the oaks from the parking lot at the summit, which is located at the end of Churchill Dr.

Daniele saw the bird in the area of the trail where the oaks first hit the conifers. The bird was in an oak tree near the first large douglas fir tree, which is located halfway down the trail. It was in a mixed warbler flock consisting of Orange-crowned, Wilson's, Townsend's and Yellow-rumpeds Warblers.

Ann Nightingale, David Allinson and Mike McGrenere relocated the bird at 1:10pm on May 15th. It was between the 2 douglas firs between the tower and the power lines.

The bird was last seen on May 16th at 8:45pm by the cell tower at the top of the summit on the power line side. It was also seen earlier in the day on the SW slope (48.491307, -123345836) and in the conifer across from the sandy spot on the same trail and on the upper part of Glendenning Trail.

Despite multiple observers looking there was no sign of the bird on May 17th.

This trail is very steep and not for those who have mobility issues. The gate to the summit parking lot opens at 12pm.

**Upon review of new photos (see HERE), the amount of green on the back of the bird concerned me, along with the dark streaks on the bib corner (the area on the side of the chest where the wing tucks in, which is often hidden by the wing) and lower flanks. I have sent all available photos of this bird along with my concerns to a few experts. They were made aware that the photos that concerned me initially were taken in evening light. All information will be sent to the Victoria and BC Bird Records Committee. I will also update the blog with any major developments.

I believe that it is important to be completely transparent and wanted the public to be aware that Silu Wang gave her opinion. She is a Ph.D. candidate in the D.Irwin Lab at UBC and studies Hermit Warblers in the hybrid zone, in the Cascades Region of Washington State. She explained that the bird has a predominantly Hermit Warbler plumage background, but with Townsend's Warbler plumage introgression.  She used the hybrid index based on the eight plumage landmarks as specified by Rohwer and Wood (1998). She was presented with all available photos of this bird and viewed them carefully. She estimated the hybrid index (ranging from 0 to 1, with 0 being pure Hermit Warbler and 1 being pure Townsend's Warbler) and for this bird she felt he should have a hybrid index of 0.12, which is smaller than 0.25 (the cutoff value for Rohwer & Wood 1998 classification). Therefore, based on Rohwer and Wood 1998 classification, it should be a Hermit Warbler. 

However, the fact that it has a hybrid index of 0.12 instead of 0 means that it does not have a pure Hermit Warbler plumage, and that there are some traces of Townsend's Warbler introgression.

She noted that on another photo by Liam Singh, showed a greenish wash close to the tail covert see HERE She said that some hybrids only show a greenish upper back, and the fact that the green goes quite far down for this bird, further supported TOWA introgression. 

She also looked at the video I linked to above by Geoffrey Newell. In that video she noted that when the bird was preening his crown was light grey, but the grey went quite forward, see screenshot HERE

She explains that she views this bird as a Hybrid, despite Rohwer and Wood (1998), as stated below:

Rohwer and Wood 1998:  Hermit Warbler (because Hybrid index =0.12 <0.25).

Wang et al in prep:            hybrid (because Hybrid index =0.12, not 0).

RBA: ASH-THROATED FLYCATCHER in Victoria - May 14th

At 8:15am on May 14-2017, Ann Nightingale, Kim Beardmore and Jannaca Chick found an Ash-throated Flycatcher. The bird was in a large bush on Lohbrunner Rd East between Blenkinsop Rd and Lochside Trail. The bird was originally misidentified as an Olive-sided Flycatcher, due to poor lighting and brief views but was photographed. Upon review of photos, many hours later, it was discovered to be an Ash-throated Flycatcher.

Word was put out at 4:40pm and a few people searched for it but it was not seen again. It was last seen flying towards Little Mount Doug at 8:15am, after being chased away by an Anna's Hummingbird.

RBA: MURPHY'S PETRELS off the north end of Vancouver Island - May 10th

On May 10-2017, while aboard the "Grand Princess" cruise ship, Paul Lehman and Bruce Rideout found 4 Murphy's Petrels in BC waters near the Brooks Peninsula. One of the birds was photographed by Bruce Rideout and this bird was the furthest north that Paul had ever seen the species in BC.

The locations for the four birds were:

48.009, 129.720  (ca. 280 km SSW of Brooks Peninsula, V. I.)

48.435, 129.993  (ca. 248 km SW of Brooks Peninsula)

49.106, 130.428  (ca. 216 km SW of Brooks Peninsula)

50.517, 131.361  (ca. 209 km W of north end Vancouver Island; photographed)

RBA: LESSER NIGHTHAWK in Victoria - May 7th

At 10 am on May 7-2017, James Paterson photographed and reported a bird identified as a Common Nighthawk to eBird. Upon review of photos this morning, it was discovered that the bird is actually a Lesser Nighthawk. The white wing bar that appears in line with the end of the tertials, the blunt wing tips, the pale buff spotting on the wing coverts and the fact that there is no dark tones in the mantle or scapular that Common Nighthawks typically have, along with the early arrival date, all helped to confirm the bird as a Lesser Nighthawk.

The bird was found perched in a tree near 3491 Camcrest Place at Mount Tolmie Park.

Map to exact location HERE

Multiple observers have been looking for the bird on May 8th but as of yet, it has not been relocated.

This is the third record of Lesser Nighthawk for Vancouver Island and 4th for BC.

RBA: MANX SHEARWATER off Ucluelet - May 7th

At 1:15pm on May 7-2017, while aboard the MV Frances Barkley, young birder Liam Singh (13 yrs of age) spotted a Manx Shearwater during the WildResearch Pelagic and BCFO Young Birder Field Trip. The bird was located 6 Km SW off of Amphitrite Point. It was viewed by multiple observers and photographed.

GPS coordinates were N 48.89931° W 125.62473° 

This is the 57th record for the province of BC.

RBA: BLACK-TAILED GULL in Gingolx - May 4th

At 7 am on May 4th-2017,  Jeremy Gatten was working along the Gingolx (Kincolith) waterfront in the Nisga'a Nation, when he found an adult Black-tailed Gull. He was scanning through hundreds of Mew Gulls just south of the Kincolith River off the north end of Waterfront St, when he spotted a dark gray-backed gull. The yellow bill with black subterminal band and red tip was immediately noticeable to him and he was able to see the bird in flight. Seeing the tail with white base and thick black band surrounded by a thin margin of white, allowed him to confirm that it was in fact an adult Black-tailed Gull. He was able to photograph the bird as well. The Eulachon run ended last month and the decaying fish has brought in thousands of gulls to the Nass River Valley.  He will be in the area for another 4 days and will be monitoring the gull's presence.

Map to location HERE

This has been an incredible year for provincial rarities for Jeremy. In addition to the Black-tailed Gull, he has found a Purple Sandpiper, Redwing and a Black Phoebe.

The Black-tailed Gull has not been seen since May 4th but very well could still be in the area.

This is the 2nd photo-documented record of Black-tailed Gull in the province of BC.
