Book excerpt: Excerpt from Field Notes on Amphibians, Reptiles and Birds of Northern Humboldt County, Nevada: With a Discussion of Some of the Faunal Features of the Region At the present time it is coming to be realized that there are other characters distinguishing species than those brought for ward through morphological researches, as, for example, those belonging to the domains of physiology and psychology. These characters, being less accessible and sometimes less tangible, offer more obstacles to precise definition than those others dealing with structure. Nevertheless, traits, habits, manners of perform ing particular acts, preferences of one kind and another, seem in most cases to be as definite and as constant characteristics of species as the shape and size of bill and feet, or coloration of fur and configuration of skull. An attempt has in this paper been made to place the emphasis upon such non-morphological characters, here mainly psychological.
