    Yellow-billed vs Medium Egret

    Thank you for the replies. Based on this discussion and what I've been able dig up online, I've written the following post on my website. I've pretty much come to @johnallcock 's conclusion: Medium and Yellow-billed likely can't be separated in the field when not in breeding/courtship plumage...

    Yellow-billed vs Medium Egret

    Hi. Thanks for sharing this. The paper notes differences in tibia color in non-breeding birds--yellowish to pale brown in A. brachyrhyncha and dark green to brown/black in A. intermedia. Pouring over images of both in Macaulay Library, tibia coloring in A. brachyrhyncha is noticeably lighter...

    Yellow-billed vs Medium Egret

    Thanks for weighing in, Jon. Re dark tip to the bill, that's the impression I had been under. All of the birds documented in southwest Saudi have shown this feature, which led me to question the wisdom of bulk changing all "Intermediate" observations in eBird to Yellow-billed, despite the...

    Yellow-billed vs Medium Egret

    Besides when they're in breeding plumage, are there any features one could reliably point to for separating these "Intermediate" Egrets? The reason I ask is that sightings in southwest Saudi are all now presumed to be Yellow-billed. However, in southern Oman, they're presumed to be Medium, and...

    Saudi Arabia Feb-Mar 2023

    Awesome trip report, Jan! Just a note about gender segregation on the ferries. This doesn't apply to non-Muslim tourists. While female visitors will be directed to sit in the female-only area in the terminal while the men prepare the vehicles for inspection, inside the ferry female travel...

    ID for juvenile warbler in Oman

    Yes, northern Oman will be Delicate (carpenteri) and southern Oman (Dhofar region) is Graceful (yemenensis). Lots of undeveloped desert between the two regions but surely there's a contact zone somewhere...

    ID for juvenile warbler in Oman

    Hi there. If you've got photos of prinias from your time in the EP, I'd love to see them. We suspect both Delicate (P. l. irakensis) and Graceful (P. g. hufufae) occur around the Dammam area. Strong evidence for the former but none but audio for the latter. Cheers!

    Blyth's Reed?

    Hi all, I apologize for the cruddy shots and unfortunately none with an unobstructed view of the wing, but besides coloration is there anything by which we could support Blyth's Reed? More prominent forward supercilium, dark lores, dark tip to the under side of the beak, seemingly short primary...
