Re: [Maine-birds] unusual crow

This sounds much more like a crow with damaged wing feathers, such as from a feather mite infestation or certain deficiencies, such as described here: https://morgithology.blogspot.com/2010/12/feather-de-pigmentation-in-carrion-crow.html. It's fairly common in American Crows and birds like this are seen regularly. Shorter flight and tail feathers from damage and abrasion would make it look smaller, force it to flap quicker, and I have seen feather mite damage at the base of flight feathers that makes the wing look just like that (reminiscent of a Pileated Woodpecker).

For the third time in about a week I have seen what I am taking to be an aberrant crow near the West Gardiner travel plaza off of I-295. It is noticeably smaller and shorter-winged (flaps twice as fast as the crows it is with) than the typical American Crows it consorts with and it shows a thin white stripe at the base of the flight feathers so that it looks like it has a thin light stripe down the center of the wing when flying.  A few months ago we caught a quick look at a crow with a similar wing pattern down in Yarmouth as we were driving south on I-295. Wonder if this is the same bird or if multiple birds are showing up like this?

 

Anyone else seen this bird?
