Head, hood, and breast and slightly further down of breast bright yellow, eyes dark, no black mask, beak is milky white, wings and tail are white with two or three center feathers (flight feathers) black, tail is the same white with two or three feathers center that are black, legs are a horn like grey, back of bird is blotchy black and white. Bird is 9 to 10 inches in length
Behaviors: Bird arrived in small marsh area Sunday May 1st. There are 10 other male yellowheaded Black birds in the same small area. The call and song is the same as the other male yellowheaded black birds and streatcheds its one wing and then both wings the same as the others. The head lift as it calls are the same. There are no trees in this area so seeing it sit on top of cat-tail reeds is the same and territory defense calls and hoping with wings out and short flights the same. Also does the fly in circle as the others. First I thought it was a molt until I could see the the head of the bird had no black eye ring or line or mask if you will. It also makes the same kind of croking sound when agitated. The other yellowheaded blackbirds did not run this bird off as they did the red wing black birds, boat tailed grackles common grackles or brewers blackbirds even hous finches and common house sparrows. It has set a territory and is defending it. I have videotaped this bird on several occasions and have had the sighting verified by photographer Bill Schmoker who came up today May 7, 2011 and spent hours photographing it.
Call: harsh raspy decending with a buzz
Plumage: yellow white and black

Because I work at the hotel Isee these birds every day. I have counted the increasing number of males arriving each day as I have done the last 2 springs. I have recorded there song and calls and videotaped them flying stretching hopping and defending their territories as this is sucha small area with very little or no obsticles in the way. The yellow headed black birds are very territorial and each spring win out these territories from the red winged black birds and any other bird including grackles and other blackbirds like brewers and boat tailed grackles. Their flight to that is very swift starting low and swings in a circle usually. When this bird first arrived it seemed very tired and slightly clumsy as others behave, the other yellowheaded black birds did not chase it off. Two other yellowheaded black birds came and positioned themselves on either side of it and stayed near it but non agressive for quite some time, most of the morning and early afternoon on May 1. I thought it might be molting until I observed a full view of its head and beak and heard its voice. The next day it was much more active.
Showed some of the video footage to Abby Churchhill of RMBO and spoke with Jeff Birek a biologist from the RMBO Ft Collins office and gave hime all the field marks and some behavior indications. He sugessted to get a photographer out there with a longer lens. Bill Schmoker a Bird & Wildlife photographer came out a nd spent several hours today May 7th, 2011 from around 7:30 am to well after 9 am photographing it. He agreed that it was a partial albino yellow headed blackbird.
I have done so above
