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.
