Hunting habits of hawks
Hello, I'm new to backyard birding and when all the birds who had been eating from my feeders suddenly left for a few days (squirrels, too) it was suggested that they knew a hawk was nearby. We live in a fairly wooded neighborhood where houses sit on 1/3 acre lots and a lake is within 1/4 - 1/2 mile, surrounded by heavily wooded area where numerous birds live.
The only time we have seen a hawk (that appears to be young) is after dark while walking the dog. I thought I might have seen a bird larger than those that visit my feeders fly off with something in its talons one afternoon awhile back.
Do hawks hunt in the daytime or at night? Do they perch and wait for prey or soar above and area first? Is it true that if I place my feeders under a tall tree with a large canopy that hawks will have more trouble spotting it?
Thanks for any information you can give me.
