There's a flock of crows, sassy, bossy, social, also anti-social.
I suspect that a bluejay stashed food in this little hollow. The crow spotted the stash.
Winner take all.
More screaming. Another hawk. Go away!!! Caw! Caw! Caw!
Finally, I could get down to trying to find this woodpecker. It also was marking off its space. It chased pigeons and downy woodpeckers. It's voice is distinctive, clicky. Interestingly, it didn't interact with the crows and they left it alone. This little bird does its pecking high in the trees so getting an ideal shot is very hard. It doesn't yet have the red head feathers, but there's a glimmering of what's to come when the sun hits its head.
I stayed in this area more than an hour and behavior was non-stop,- screaming crows, hawk chasing, woodpecker chasing space invaders, small birds on other side of transverse hunting for food near edges of bushes very hawk-aware. When the hawk swoops the tiny birds vanish into the bushes and the squirrels freeze on the side of the tree. Survival. And all the while screaming crows. CAW!!!
