Lifer Black-backed Woodpecker

At least in NY, black-backed woodpecker nests always used to contain multiple nestlings, but a few years ago this started to change, and now all nests contain only one fledgeling.

 

I believe that some sort of local branch of the federal government was available to study this (it could serve as a warning sign for the whole ecosystem and as such for the local economy), but if my memory serves me, either personnel was laid off or funding was cut.
