Until you tell me otherwise, tho, I have a question. The finches were chirping up a storm up until a minute ago and all of a sudden, with the first call of a crow, got quiet and have remained so. How did that crow, which left as soon as he arrived, scare them off? Would a crow chase or otherwise attempt to attack finches?

Inquiring minds want to know.
