Nickerson Beach Park, Nassau County, Long Island, New York, USA June 4, 2019 Not sure if this is an immature Common Tern or Roseate Tern. Would appreciate help on this and tips on how to distinguish these two as first summer birds. Bill looks a bit on the thick side, favoring Common Tern, but...

Palo Verde National Park, Guanacaste, Costa Rica, March 19, 2019 Having trouble distinguishing between immature Gray-headed Kite, Collared Forest-Falcon, and maybe Bicolored Hawk on this bird. For what it's worth there was an adult Gray-headed Kite in the same area.

Palo Verde National Park dry forest, March 18, 2019 I know the shots are bad but seems like might be possible to work with. I'm seeing a fairly short bill, dark throat and upper breast, white belly, solid green upperparts. I considered Canivet's Emerald, Blue-throated Goldentail, Ruby-throated...

Scaly-breasted Hummingbird

Thanks for the input. For what it's worth, I considered Empidonax in the field and decided that this bird was decidedly more like a pewee in shape and habits. No hint of an eyering and the slender elongate shape (albeit distinctly less so than Eastern/Western Wood-Pewees) were the main things I...

Near Pocosol Biological Station, Alajuela, Costa Rica, March 16, 2019 Looks to me like Tropical Pewee, but I'd like to hear others' thoughts.

Thanks for the input, all. Best to leave it at Turdidae I think.

Pocosol Biological Station, Alajuela, Costa Rica, March 15, 2019 Observed this thrush which I noted had a yellowish bill and eyering, dark slaty cap and back, and pale underparts. I got these poor photos. Structurally looks like a Turdus to me rather than a Catharus nightingale thrush, and...

Thanks, that's what I was thinking as well but wasn't sure!

March 14, 2019 at Pocosol Biological Station on the Caribbean slope of the Bosque Eterno de los Niños. Is this a Variable Seedeater or Thick-billed Seed-Finch?

bumping this up, since no one responded

On second thought, could that crow spread tail picture be a misidentified raven? The wedge shape looks too strong, the wings look long, and the primaries look nice and long and finger-like...

I can't say for sure one way or another based on your description. I haven't heard of any crows imitating ravens, but I don't see why it wouldn't happen. That said, I'd expect you to hear both crow calls and raven calls if this were what's happening. Size is often not a useful field mark for ID...

Hi all, 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 wondering if anyone has any recommendations for a tree identification field guide for North America. In particular, I'm interested if anyone has had experience using the National Audubon Society Field Guide to Trees (Eastern Region), Golden Field Guides: Trees of North America, and/or...
