[Cooper's?]

Cooper's Hawk is correct, given the dark brown globular streaking fading at the belly, overall apparently large size, and long tail.

[Gulls Galore]

1. Any more photos? Looks good, but I'm not positive. Any photos showing the uppertail or wings better would certainly help. I'd say 90% you're right about Lesser Black-backed Gull though.

[What kind of Wren? Huntington Beach CA]

I agree with House Wren based on long tail, lack of supercilium, and lack of any other bold patterning.

[Cackling Goose?]

I agree that these are Richardson's Cackling Geese (Branta hutchinsii hutchinsii) based on very small size, very small bills, and very short necks.

[Which finch?]

Agree with House Finch based on extensive dark streaking underneath, curved culmen, and overall not extensive enough red/purple.

[Gull ID appreciated.]

I agree with Herring Gull based on the hefty bill, pink feet, and extent of black on the wingtips. Nice shot.

[Canada/Cackling Geese & subspecies: Alaska (Anchorage)]

These geese were photographed at the mouth of Ship Creek in Anchorage, Alaska, on June 2, 2018. I believe them to be Dusky Canada Geese (Branta canadensis occidentalis. However, this subspecies group (Dusky/Vancouver Canada Geese (occidentalis/fulva)) is flagged as rare in eBird, and I'm not sure Dusky Canada Goose actually does make it into the Anchorage area. However, the group of geese (only two photographed, silly me) looked as a whole considerably darker breasted and darker overall than our local Canada Geese on the East Coast of the US (subspecies maxima and canadensis). I believe most of my attached photos show this except for one in which the color is more washed out by lighting effects. Though the dark coloration overall would be in line with the minima subspecies of Cackling Goose, which would occur in the area, the birds seemed too large and long-billed for any subspecies of Cackling Goose (and too dark for Taverner's).

All photos show the same bird. In the one with two birds, the bird pictured in the other photos is the goose in the back.

I'd love to hear thoughts on these birds' subspecies, but would also appreciate simple confirmation that they are not Cackling Geese, as I admittedly have no experience with any of the western subspecies of Cackling Goose.

[Philadelphia Vireo? Southern Quebec, September 2018]

Yes, given the extensive yellow on throat and undersides, dark lores, and blueish legs and feet, this is a Philadelphia Vireo.
