Hab. NortHern AND Western Nortu America, from the Mississippi Valley west- 
ward §.—Mexico 1°, Guaymas (Palmer ®°, Kellett & Wood '°), Guanajuato and 
Guadalajara (Dugés!%), Valley of Mexico (Herrera+®, White? ©), Vera Cruz, 
Laguna de Epatlan, Jalapa (ferrari-Perez"); Guaremaua, Atitlan 5000 feet

This is the American form of the Eared Grebe of Europe, and is stated to be only a 
winter visitor to Central America; but specimens in full summer plumage have been 
obtained in the Valley of Mexico and in Guatemala, so that it is possible that the 
species may breed there, though at present we have no direct evidence to that 
effect. 
The habits of P. californicus are similar to those of other species of the genus.
