Katie and I saw the Western Flycatcher again earlier today and got photos from various angles, which we added to our eBird checklist: https://ebird.org/checklist/S123453146

It was foraging on the ground and going from low branch to low branch, not where I'm used to seeing Empids. One of the photos shows it with very wet feathers. I hope it can make it through this winter weather...

Will be interesting to see if this bird lingers and if anyone else gets lucky enough to see it.

This bird is intriguing.  Overall matches a Cordilleran ("Western") Flycatcher in many respects but one of the key fieldmarks (to separate this from even rarer possibilities) is the primary projection - how far the primaries extend past the secondaries when the wing is folded.  Since this bird isn't completely folding its wings in any of these pictures (probably because it's COLD!), that makes it hard to judge but it appears longer than usual to me.  I've just sent this to a few friends back east to get their impression ...

Hi Tom

 

Was this from today?!  Which part of the park?  That's quite late (2+ months) for an Empidonax flycatcher to be still hanging around at this latitude!  Any other photos of this bird?

Goshawk at eagle island

Karl Kosciuch
 

I had a large accipiter at Eagle Island State Park south of the lake near the slaughter house that checked field marks for immature northern goshawk. It was a large raptor with a distinct banded tail and notable supercillary stripe. I attached a photo and hope it comes through.

This is very sad news.
Looks like we all need to keep a lookout and report.
Could it be the Avian flu?

Scavenger birds such as gulls, ravens, jays, raptors can catch and die from avian cholera but it mostly kills en masse waterfowl and coots.

When out at Lower Dam on Sunday (Nov. 27), looks like the number of dead snow geese is approaching, if not past, 200.  They extended from the point just east of the boat ramp to along the westerly shore in the smartweed.  Also saw 5 sick and dying snow geese - 4 on the lake side and one on the canal outlet side.  There were also a couple of dead mallards - one on the steps of the dam near the top and one along the road edge.  Not sure if these are also victims of whatever is killing the snow geese or just had the bad luck of getting hit by a car.

 

At Murphy's Neck I saw at least 3 dead snow geese and 1 dead Canada goose.

 

At Upper Dam I saw 1 dead snow goose on the west boat ramp and 1 juvenile that acted sick.

 

I reported the birds I saw at Lower Dam and Murphy's neck and included some photos of 3 of the sick birds.

 

Has anything been noted at Fort Boise WMA?

Getting a bit into the weeds here and heavily speculating, but between the two groups of Western Flycatcher (Pacific-slope and Cordilleran), Pacific-slope has slightly shorter wing morphology. If the much higher number of "Pacific-slopes" vs "Cordillerans" banded at Lucky Peak has any bearing on which birds are more frequently seen in Boise (and this is a big if, the formula we use to differentiate this might not actually mean anything), maybe the projection is just long for the Westerns we typically see? I doubt this is obvious enough to be able to tell in the field and I definitely don't have the experience to say, but Jay maybe you could say if the difference could be discernable?

PS, Tom - if we settle on Western for this bird, could I use these photos with credit for a presentation on Western Flycatchers I'm giving for SIBA in December? Always nice to have photos from local photographers to feature! 

Thanks!

Re: Bird ID

Carter Strope
 

Hey all,

FWIW I think this bird looks good for a Western. I really tried to turn it into a Yellow-bellied Flycatcher, but I think the primary projection, although eye-catching, appears to be within range for Western (particularly for an out of season bird of indeterminate origin) and I can't find any other fault with that ID. 

I think the tipping point for me is the extent of buffy fringing in the secondaries. Yellow-bellied tend to have much more restricted fringing here, particularly at the outermost secondary or S1 (I'll attach a figure that shows what I'm referring to here). 

The thick eye-ring, facial structure/appearance, and lack of notable contrast point me away from Acadian as well.

Would love to hear what others think, but based off of these photos I would lean Western.

Best,
Carter

Jay, here are more pics. It was hanging out in the same area as a few ruby crowned kinglets.

Hi Tom

 

Was this from today?!  Which part of the park?  That's quite late (2+ months) for an Empidonax flycatcher to be still hanging around at this latitude!  Any other photos of this bird?

 

Thanks,

 

Jay

One last bird from Kathryn Albertson: I think this is a Cordilleran (Western) Flycatcher.

 

Any thoughts?

 

Thanks,

Jay,

 

One more pic with a slightly different perspective. Maybe it will help.

 

Thanks for the information on the bird.

Thanks Tom

 

This bird is intriguing.  Overall matches a Cordilleran ("Western") Flycatcher in many respects but one of the key fieldmarks (to separate this from even rarer possibilities) is the primary projection - how far the primaries extend past the secondaries when the wing is folded.  Since this bird isn't completely folding its wings in any of these pictures (probably because it's COLD!), that makes it hard to judge but it appears longer than usual to me.  I've just sent this to a few friends back east to get their impression ...

 

Thanks,

 

Jay
