RBA: Ash-throated Flycatcher in Port Alberni - July 1st

At 1:10pm on July 1-2017, Penny Hall found an Ash-throated Flycatcher in Port Alberni. She had good looks at the bird through her bins for 3 mins. The bird was sitting on a fence and when she approached it, the bird flew from the fence into the trees. She tried to relocate the bird into the evening but could not relocate the bird.

Directions to where the bird was last seen: Enter the trail at the bottom of Mozart Road and follow the trail along the farmer's fence line to where the big boulders are and the bird was last seen in the stand of trees right next to the cleared field.

RBA: ACORN WOODPECKER in Victoria - June 17-Aug 26th

At 4:30pm on June 17-2017, Ted Ardley found a female Acorn Woodpecker at a feeder at his home near Aldersmith Park off Burnside Rd W and Meadow Park Lane near the Eagle View Elementary school.

The bird was viewed by multiple observers as of 6:05pm.

Directions: Park along Meadow Park Lane and walk to the end where you see a small round about and communal mail box. This is one of the entrances to Aldersmith Park. Go to the right on the trail along a chain link fence and just a few yards in look over the fence at some feeders there in a stand of Garry oaks behind the trailer.

RBA: CHESTNUT-COLLARED LONGSPUR north of Golden - June 8-9th

At 6:15am on June 8-2017, Emily Williams and Emily Smith found a male Chestnut-collared Longspur, 2.5 hours north of Golden. The bird was on the east side of the Bush Arm causeway off the Bush River FSR near the south end of Kinbasket Lake. The bird was calling and foraging in the grassy area near black peat moss and driftwood. It flew across to the west side of the causeway but returned back to the east side. They observed the bird or over 20 minutes. Emily Williams relocated it and photographed it there at 9:15 am, the following day (June 9th).

The bird was not seen on June 10th.

RBA: CHESTNUT-SIDED WARBLER in Richmond - June 11th

At 8:30 am on June 11-2017, Hugh Griffith, Margaret Butschler and Steffany Walker found a male Chestnut-sided Warbler at Terra Nova Park in Richmond during the monthly bird survey for the Parks Department for the City of Richmond. The bird was singing his "pleased pleased pleased to meet you" song and moving 10 m up through the line of Douglas Fir Trees between the playground with the climbing tower and the slough which is east of the playground. The bird later landed 10 metres away at eye level on a conspicuous perch allowing for great clear views for about 10 seconds. Hugh described the bird as having a bright white underside, bright yellow cap and a black moustache. He said it also had a bold chestnut stripe along both sides of its body. He nor anyone else was carrying a camera with them and therefore did not photograph the bird. The Terra Nova Adventure Playground is located at the end of River Rd before the dyke.

The bird was relocated by Cole Gaerber in the conifers in the south east corner of the big pond at 7:15pm. It was last heard singing in the deciduous trees at the SW corner of the big pond.

The bird was not relocated on June 12th, despite multiple observers looking.

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.

The FIRST record of a HOUSE SWIFT in the Americas was found in Delta, BC!

"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: 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).
