The colony (colonies) are in two narrow draws in the hills that slope into the California Aqueduct. They are thick with nettles and some small willow trees. About 75% of the birds I saw were males. Both males and females were coming and going from the colony to a ranch across the street and out into the surrounding grasslands.
