it WAS clear plastic! i didn't have a small room to lock him in! he was fine when we got to the vet, honest... they were just like, oh no not another idiot with a wounded bird, has he gone yet? ok wring its neck..Think this might have been the moment of expiration, tbh.
I have had several opportunities to sample the flesh of crows (I will not go into detail about how this came about, but remember this is a legally hunted species). In my opinion, crow tastes just fine. It is similar to wild duck or any other wild bird with very dark meat. Crows have no white meat on them, as is true for most birds. (Whenever someone says something "tastes like chicken" remember that they're talking about the DARK meat of chicken, not the white.) The meat of most wild birds is even darker than the dark meat of chicken, and will have a gamy smell and flavor to a varying extent.
