Flocks of Robins are hunting in the grass. When I see groups of Robins scurrying on the ground in formation, I know spring is here.
Robins flock in the beginning of spring and at the start of the breeding and nesting season. I suppose the Robins are socializing, picking mates, and hunting.
They were finding worms to eat. I watched several birds gobble down earthworms. Perhaps, hunting together improves their chances of success.
The Robins cock their heads to the side when hunting. I think they are looking at the ground as their eyes are on the sides of their heads like most animals that are prey. Top predators eyes are often rather flat on the front of their faces. Think of a lion or a wolf.
The next time I see a flock of Robins, I’ll have to check to see if it is made of mostly females or males. Male Robins have deep brick red breasts and black heads. A female has a light orange or red breast and a dark gray head.
