I just now uploaded a new video. Here’s the Youtube description:
Watch a pair of cardinals feeding their two chicks as they grow from the size of a marble up to nearly as big as an adult in just 10 days. At the end a Cooper’s hawk takes both of the youngsters; a very tragic event for them and sad for us too, yet it is part of how nature works. The hawk has young to feed and songbirds are a significant food source for them.
I posted video of the first few days of this cardinal nest earlier this spring, but this version includes all 10 days of their short lives.
