Here we will have some pictures of birds in unusual plumages generally not shown in the books, but which you might encounter. The best lesson is that usually odd looking birds are common birds that have pigment abberations. If you see something not in your books, it is more likely an aberrant bird, rather than you having discovered an unknown species.

Albinism or partial albinism, or too much or too little of any color is possible.  One should use size, shape, structure, behavior and vocals to identify these abberant individuals.

Additionaly, odd plumages can be the result of hybridization, however great care should be made in claiming such. Some like Northern Flicker however produce lots of hybrids out there. The key is to get pictures so an expert can identify it.

We'll start with an odd Junco. A rufous-backed, gray-headed, pink-sided, Dark-eyed Junco, which I suspect is a hybrid Gray-headed x Pink-sided Junco.

This bird seems a hybrid to my eye. It struck me as a Gray-headed Junco due to red-rufous back and gray head and breast, but it has pinkish sides, not gray. A good Gray-headed Junco has gray sides, but otherwise it's a close match with correct bright red-rufous back color. It is also suggestive of a Pink-sided Junco due to those pink sides, but, the back is red-rufous, unlike Pink-sided.

In my view the key incriminating or definitive character showing evidence of it not being a pure Pink-sided is the gray breast which extends too far posteriorly on the underparts for pure Pink-sided, which has a distinct clearcut standard issue 'Junco' hood, lacking on this individual. So a hybrid seems the likely correct determination in this case.

It was present in our Utopia area yard winter junco flock off and on (6 days over 6 weeks) on Feb. 13, and between March 10 and 31, 2012.

Also one must consider escaped game or pet birds too, especially gamebirds and waterfowl, but not just them.

If you lost this bird please contact me.
This is one of the Mexican races of the Bobwhite.
Such things are obviously not of natural occurrence.




Below are a couple of examples of pigment aberrations in the way of "greenie," a yellow morph Pine Siskin, and "whitey" (a partial albino Chippy) that were here near Utopia during winter '06. Then there is a hybrid quail and a couple different Painted Bunting plumages, a warbler sketch and a white-winged Scrub-Jay. We'll add weirdos as we find them.

Note back color which changed with angle and light!!



Pine Siskin


Above is a "yellow" morph as they are called, Pine Siskin near Utopia, TX, Jan. 22 to late April '06. I'd say it is more oddly green than yellow. However, the amazingly green back faded as the fresh plumage wore.

Some of the photos taken through two old window panes ..... The bird had unmarked yellow underwings (linings brighter), and an unmarked yellow patch on lower back like Eurasian Siskin !&$!. Amount of yellow above on wing and tail in flight was stunning. Bird was present with up to over 80 other "normal" Pine Siskins.

Pine Siskin

Here you can see the underside of tail, a butter yellow, as were undersides of remiges (flight feathers on wing).




Here is a partially albinistic Chipping Sparrow ... when it flew it had lots of white in tail and wings, like a Snow Bunting, but in all the wrong places.

This albino House Finch complete with red eyes was in our Seco Ridge yard in July and August, 2012.
Use size, shape, structure, vocalizations and behavior to ID such oddities.




Here is a real doozy, an oddity among oddities

hybrid Quail?

Bluebob?
A possible/apparent hybrid between Scaled (aka Blue) Quail and Northern Bobwhite, near Sabinal, Texas, May '05. A few very very crack gamebird and quail folk have agreed with this diagnosis. And I've seen another since!




Painted Bunting

This is a 2nd year (about a year old) male Painted Bunting. Not really an oddity, but not shown in the typical field guides. There seem to be several avenues 1st year male Painted Bunting to achieve adult plumage, some are yellower below with some blue on the head in the first summer, more though are like this one, lime and salmon. Whooda thunk they went together so well.



Painted Bunting

This was by all accounts an adult male Painted Bunting, but which lacked all red pigment, leaving those parts yellow. Since it was not photographed, all you get is this mis-shapen thumbnail. Xanthistic might be the term for this. Interestingly a short time later one was seen I think near Junction (posted to Texbirds). Perhaps was it Birds of So.Carolina about 1910 by John Dick that illustrated this type of pigment aberration in Painted Bunting?  You should get an extra point for having seen one.   :)




Scrub-Jay

This is a texana Scrub-Jay with partial albinism, or leucisism.
One parent had a "shadow" of the pattern apparent in flight.
If you see a white-winged Scrub-Jay around Utopia please
let me know, it is from Seco Ridge.  :)




hybrid warbler

This is a hybrid Hermit x Townsend's Warbler that Kathy found over at Garner St. Pk. Nov. 1, 2009, showing characters of both parent species. One of the furthest eastward records and probably the first for the Edwards Plateau.
