So, just a few days ago, a melanistic fox squirrel appears in the yard. I wrote about that oddity in my last post. This morning I glance out the back window and what do I see? This strange and beautiful creature! It's a partially leucistic blue jay, absent the black (melanin) pigments that mark the face and neck of a typical jay. When I first saw the bird, it was consorting with several other jays at a feeder, and it stuck out like a sort thumb.
NOTE: I am referring to the animal as
partially leucistic, even if that's being a bit general. One can get extremely bogged down in what seems to be largely unverifiable explanations for various conditions of pigment anomalies. For a good general discussion about anomalies in pigmentation, with a key to place birds into six general categories of color aberrations,

As a frame of reference for our odd jay, here is a typically plumaged blue jay. The black collar, eye line and dark saddle across the base of the bill are conspicuous plumage highlights of a blue jay.
Thanks to
Julie Zickefoose (she authored
THIS BOOK about blue jays) for aging this jay as a hatch-year bird (born last spring/summer). Whatever all the factors that caused its excessively snowy plumage, it is a beauty. The jay has been coming in to the feeders intermittently today, usually in the company of several other jays. I hope he sticks around. I'll certainly try and help by keeping the jay smorgasbord going.
