🪶Help me out, #ornithology folks of #BirdSky! Curating @ntlmuseumsscot.bsky.social collections for digitisation, I found this labeled Stripe-tailed Yellow Finch (Sicalis citrina), which it's NOT. #SouthAmerican #birds ≠ my forte: is this a Blue-black Grassquit (Volatinia jacarina) or something else?

It's a small bugger, collected in end of April in Bartica Grove in northern Guyana. Wing length 49 mm. I'd be very happy for your input! #LBJ #MuseumLife

It does look like a juvenal / female Volatinia jacarina indeed!

Excellent, many thanks Alexandre! It's really, really worn, so I'm guessing it's an adult female (with the caveat that I don't know their moult pattern).

Have you tried Guy Kirwan, Martin? Not on Bluesky but you’ll be able to get his contact details from BullBOC.

Hi Steve, Guy was going to be my next step if the BlueSky hivemind doesn't solve the issue!
