Tuekey Vulture

This is a juvenile turkey vulture! They are starting their migration south! I love baby TVs! Great shot!

http://www.examiner.com/article/turkey-vulture-identification-guide This may be of help.

The color pattern and shape is consistent for a juvenile Cathartes aura. They have dark heads but have the silvery flight feathers like the adults. The head shape doesn't look right for me for Cathartes burrovianus.

I thought of Cathartes aura also, but is has dark brown feathers, and not the whitish remiges and tail feathers; only Cathartes burrovianus has that.

@Bayucca. I just posted my comment and my Internet connection cut off. So here I go again. There is a population (or subspecies) C.b.urubitinga, that inhabits most parts of South America, and a population C.b.burrovianus that occurs further north, including all of Mexico. Well, Arizona is just across the border, so it is quite possible that some individuals are seen there. Furthermore, the black vulture does not have those whitish remiges and tail feathers, and its head is more rounded. The head of Cathartes burrovianus is yellos or pale orange, with blue or reds patches, and yes, I do see some red also. Conclusion: this is not Coragyps atratus.

After checking the colors again, I might see some "reddish" on the head, so it is a Turkey Vulture, which would match with the two-colored underwings as well. What do you think? Can you remember some reddish head? Do others also see some "red"?? http://www.gardenersreach.com/Conservation/v-is-for-vultures/ http://www.allaboutbirds.org/guide/black_vulture/id http://www.projectnoah.org/spottings/17160311 Or do I need new glasses???

@Emilie. I was actually wondering about the color shades on the underwings: color or shadow?? Could you, please, check the range of your suggestion? According to my quick search, Cathartes burrovianus should not be found in Arizona. http://en.wikipedia.org/wiki/File:Cathartes_burrovianus_-flying_-Argentina-8.jpg

This should be a Black Vulture. http://www.flickr.com/photos/racitup/8536995668/
