Banks 1960 Xantus Hummingbird Oct. 24 E side Isla Cerralvo, Baja Calif., Mexico. I have seen this species previously in the week, but until I collected one today was doubtful of recording it. The species was fairly abundant in the upper reaches of the arroyos. Here I observed 2 chasing each other back and forth, beyond where the spring is. They were feeding at a blue flower.
