Earlier today, I watched thousands of crows fly into Auburn, NY over a span of 10 minutes. Every fall, a murder of crows (50K-75K) descend on Fort Hill Cemetery, formerly an ancient Indian burial ground, in the late afternoons. At night, they all go a few blocks northeast to the downtown area, where they will roost through the nights. It’s been happening for over 100 years. Some say the crows are the spirits of those buried.
