I think crows are either too stupid or they are unnecessarily brave. I have seen that they make their nest in the most difficult of places. This nest is at the top of a tree it is very difficult to sit there in strong winds and rains. I saw three eggs there a few days ago. Now the nest is gone and I don't think even a single of those eggs hatched. I have seen nests in other impractical places as well in the last 4 years. I am wondering if the crows were a little more careful about selecting a place for their nest, their population would have been a menace.
