Behind my office is a Southern red oak in decline. Limbs have been trimmed and the top has already broken, although we're not inclined to take it down just yet.
My colleague pointed out to me this morning that a pileated woodpecker
was busily working a cavity high up on the trunk - what a great sight.
This is a blurry image from early morning (cropped, of course!).
It's probably a feeding cavity based on my bit of research, although I'm
hardly an expert on bird behavior. Not the time of the year for a
nesting cavity, certainly, and pileated woodpeckers forage in dead and
dying trees in search of a favorite prey item, carpenter ants, according
to All About Birds, Cornell Ornithology Lab's online field guide site.
