Why do we never see baby crows?
One of the Crow Questions I hear most often is, “Why do I never see baby crows?” In truth, it is likely that we have all seen plenty of baby crows–but we are misled by the human tendency to conflate “baby-ness” with small-ness. A few crows will jump from the nest before they are grown, and cannot yet fly.
What do crows do at night?
At night, they are almost defenseless, so they gather in large flocks to roost in a spot where they have good visibility and reasonable shelter. Although crows congregate in rural areas, if there is a town nearby, they’ll take advantage of it. Cities offer benefits.
