Bonus Golden-cheeked Warbler in Cerro Punta, from 2008


Says Jan Axel Cubilla:
While admiring Osvaldo Quintero's huge photo gallery, I found the attached photo. It was labeled as a Black-throated Green Warbler, but I think it is an adult male Golden-cheeked Warbler! Despite that I cannot tell if the underparts are completely white due to the quality of the photo, I think the black line through the eye is very distinct, and quite different from the olive auricular patch of the Black-throated Green Warbler. He took the photo in Volcan (no more details), march 15th, 2008. What do you think? The third report of Golden-cheeked Warbler for Panama, and the first with a photographic evidence?
George Angehr concurs:
I think it is definitely a male Golden-cheeked. In addition to the black eye line, which slants upward at the end to join the nape, the crown is black instead of olive as it would be in Black-throated Green. I think the yellowish tone is due to the sunlight filtering through the leaves.
Congratulations to Osvaldo, as well as to you for recognizing it.
Yes, this is the third record, and first photograph.
Rafel Luck, who was with Osvaldo on that fateful day, adds that the bird was seen at the beginning of Respingo trail above Cerro Punta.

Osvaldo checked his files and noticed that he took the photo in the road to El Respingo with a local guide (Ito)... the site where this warbler was reported the two times before

Not to rain on the parade or anything, but when I first saw that photo I thought "black-throated green in bad light." It's certainly interesting looking, but to me the crown actually looks like it would be green in good light, and the back definitely looks green, not the dark or blackish back with maybe green feather edging I'd expect from an adult male golden-cheeked. One of the most troublesome marks is the apparent dark outline to the bottom of the auricular, which I think is very rarely present (if ever?) on golden-cheeked but which is always present to some degree on black-throated green. Check out these photos for black-throated greens with similar looking faces (just imagine them in really bad light): http://gerritvyn.photoshelter.com/gallery-image/Warblers/G0000.rZ5wt_T0I4/I0000WEmQmXmRWNs and http://www.photographersdirect.com/buyers/stockphoto.asp?imageid=254125

basically, if you lightened everything up on that bird's face, I think it would look like a standard male black-throated green. Just my two cents- take 'em for what they're worth :)
