Easier time breeding than other species. They can stay home and get stronger and wiser while at the same keeping their eye on the neighbors just in case. They can seek a new territory of their own. The can join a sibling and co-parent. They, in fact, have a Greg at deal of choice. The males may be better off from the females!
I have seen a large flock which comes day after day to the same venue winter and summer. I have a couple of them who visit my planet boxes daily at roughly the same time. Ther e are no changes to the boxes and they make the same rounds daily. I have also watched one individual observe a bluejay walk about my roof looking for just the right place to hide his goodie. He finally found the right spot and cached his mor sel and flew off. Within a minute a crow appeared and followed the exact route of the bluejay, found the tasty morsel, snagged it, and then flew off with his prize. I was fascinated and most impressed and decid Ed to learn more about
crows. They certainly are worth watching!
