There are usually anywhere from 3 to a dozen blue jays that visit my feeders everyday and yesterday I noticed that one of them had lost all of it's tail feathers, I'm guessing it was a lucky escape from a cat or possibly a hawk( rarely I see a hawk stop by but the blue jays usually drive it away). Will this blue jay's tail feathers start to grow back now or will they not grow back until next year when it molts again? The Jay can still fly fairly good but I can tell it has to work harder than normal and am a little worried that it might have a hard time getting through the winter.
