The resident female beaver in our park was attacked twice, the first (coyote or otter, I'd guess) leaving a deep infected wound, and the second (probably a dog) beating her up until she died, probably just stopping her heart from stress/terror. I moved the carcass away from the heavy-traffic area in the park, took the skull to make a display, and did an amateur necropsy, curious about the cause of death. She was carrying a solo pup, and it was just amazing to look at--so perfect, so beautiful! We took some photos and then donated it to the local Zoological Museum. I figured this is the ONLY place I can share these photos without at least some people freaking out "Ah, it's a dead baby!" Yes, it is, but it's still something that, without the mother dying, I'd never have been able to see and appreciate. At least she wasn't hit by a car and left to rot at the side of the road! Instead, relieved of her head and intestines, her organs and meat were left exposed to the critters, and I saw a cool turkey-vulture making the most of it a couple days ago.
