New mystery next box occupant
I'm in western NY state. I have a standard bluebird box that finished up a pair with 3 nestlings in the end of June. The next box was then cleaned out.
I went on vacation the 2nd week of July and returned to find the hole chewed to enlarge it and the box half full of lawn grass clippings (both dried tan and dried green). No depression, like a nest bowl, just half full. The hole is barely larger than it was being more beveled now than actually larger.
I know I have both gray and red squirrels around. I live in a rural area and I consider both to be infrequent in my yard. I've seen baby reds and I have 1-2 gray squirrels that visit the feeders on and off. I also have chipmunks and assume (do to range) flying squirrels.
Any idea what it could be? I've been watching it with binos and have not seen anything during the day.
I cleaned the box out and I'm not sure if I should replace it do to the hole damage.
