Earth Day

This beat-up skull comes courtesy of a Great Horned Owl. The owl chomped this down and then spit it back up after the bird’s battery acid stomach had a go at it. I think these might be the remains of a Grey Squirrel skull. Found with plenty of grey hair smushed into the cavities. Cleaned up a bit with toothpick and hydrogen peroxide, but it was already virtually bleached by the owl. Check out these incisors and molars.

Forty-nine years since the first Earth Day. Here are forty years of measurable transformations in migrating birds: a new study finds warmer temperatures are decreasing body size and increasing wing length.
