    Question from Pennsylvania, USA

    Makes sense. The bill did look big to me but I was unsure if the angle was causing that and expected to see at least some iridesence in the feathers even in the shade but they're all species I only see very infrequently.

    Question from Pennsylvania, USA

    Great-tailed Grackle and Brewer's Blackbird would both be very uncommon to exceptionally rare for the location. Brewer's has yet to be seen in PA this year and Great-tailed Grackle never as far as I know. It lacks the metallic purple or green of a Common Grackle. I'm more familiar with...

    Suriname - Tropical mockingbird?

    Yes, I think so. Juveniles can be darker although the coloration is still odd to me. The only other option would be Chalk-browed but doesn't seem to have the light, broad eyebrow for that.

    Remarks on the Costa Rican expeditions of Ridgway and Zeledón

    A fascinating read, thanks for sharing. I'm just about to start reading Ridgway's biography "The Feathery Tribe" so this ties in as a nice precursor.

    Panama and Costa Rica February 2024

    Love it! I've got one of my favorite photos I've taken so far is of its counterpart the Black-crested Coquette. And then today I managed #47 of 52 hummingbird species in Costa Rica, with the White-bellied Emerald that just showed up for the first time in around 100 years...

    Panama and Costa Rica February 2024

    Can definitely recommend Las Cruces research station at Wilson's Botanical Garden. Fantastic spot to stay and get some middle elevation species from the South Pacific of Costa Rica. Jealous you got the Coquette, I've dipped on it on both my stays there so far. Going to try again in a few weeks!

    Trochilidae

    That second to last sentence is interesting (besides just the type of "support" instead of "supported"). I suppose they're saying there is appropriate habitat for it in Panama, but as far as I know, it has never been recorded in Panama. Very close to the border, yes. Costa Rica only has 4...

    Your Most Recent "Life" Bird

    This one was a half lifer for me on Monday. I count heard only birds for my Life List but also maintain a list of those heard onlys. I was finally able to see (and film, photograph and audio record!) a central American Pygmy Owl. Video: ML619090227 - Central American Pygmy-Owl - Macaulay Library

    Costa's or Anna's Hummingbird? - Palm Springs, CA

    Thank you!

    Costa's or Anna's Hummingbird? - Palm Springs, CA

    Seen in Palm Spring, CA in early April. Looking back through my photos from a trip and want to make sure I get the ID right on this one. I think it's a female Costa's Hummingbird but want to make sure it's not an Anna's. Not sure how separable the females are, could always upload it as Calypte sp.

    Do hummingbirds use kapok fiber?

    I don't have access to the PDF but it seems like the abstract of this paper hints that they would. My gut reaction is also that yes, they likely do as they're quite resourceful when it comes to nest building materials.

    Unknown Vocalization in Eastern USA - Phoebe?

    It seems to be a combination of the Pi-teer vocalization in Pieplow's book with another vocalization someone sent me that was documented in a 1970 paper on display calls in Phoebes. A local reviewer said he's heard that call usually in April when they're establishing territories and I did see...

    Unknown Vocalization in Eastern USA - Phoebe?

    I was processing some recordings I made on a recent trip to the United States. I initially thought this recording was of an Eastern Phoebe, but it doesn't seem to match up well with that. Talking to a few people they suggested maybe a very vagrant Black Phoebe? For now, I've uploaded it as bird...

    Costa Rican Taxonomy

    I know it's not Pacific, but I can't remember if it's Tropical or Middle-American (memory says the latter). Edit: just found the reference. Yes, it's a local population of Middle-American on the Nicoya Peninsula that also maybe (unclear, but what I've heard) vocalize a bit distinctly from the...

    Costa Rican Taxonomy

    Resurrecting this thread to add that the bird he proposed as Skutch's Screech-Owl (side note, if eponyms don't go away it would be a travesty for Skutch not to have a bird named after him) is currently recognized by eBird as Puntarenas Screech-Owl [undescribed form] as of the 2023 update. It's...

    Caprimulgiformes Limits

    I didn't want to hijack this thread that is more focused on Nightjars. Someone asked me today if hummingbirds were in Apodiformes or Caprimulgiformes and I said Apodiformes...but then it was brought to my attention that Birds of the World classifies what was Apodiformes as being part of a...
