Once you start, you just can't stop
In other field excursions for work, I've had some unpleasant sightings. First my first dead black bear carcass in the woods. It was mostly bones, but a paw was intact. Interestingly the head was gone. I'm not going to post this pics. Then we went and explored some new bird boxes at a site. We saw feathers and wings sticking out of the bottom of the box. We touched them with no reaction. Once we opened the 2 boxes, we found 18 dead adult tree swallows. From doing some research, it seems that perhaps the tree swallows were so weakened from the migration that they were unable to climb up the smooth box inside to get out. Plus they are not the best climbers. We scooped the birds out and the next time I go out there, I'll try to roughen up the box front insides. I also emailed the person who I think put up the boxes to let him know.
