I wonder if it's likely that one person or a group of people are responsible for killing all these birds. It seems very specific and intentional to me. As if someone has some problem with these eagles. If you're close enough to shoot the bird from a shotgun (with bird shot) you're close enough to be able to tell a difference between a bald eagle and a crow. It makes no sense to me unless the person/people specifically went there to target eagles. Do people there often have chickens outside? Perhaps it is some sort of revenge for killing chickens?
