Birds From Coahuila, Mexico

BY EMIL K. URBAN

INTRODUCTION

The following account is a summary of the present knowledge of the
birds of Coahuila. Some 500 specimens from Coahuila in the Museum of
Natural History at the University of Kansas are the basis for this
report; these are supplemented by records of birds previously listed
from the State.

In Coahuila, habitats vary from those characteristic near tree-line to
those of the floors of the low deserts. Because of the variety of
habitats, many kinds of birds are present in the State; at least 312
living named kinds of 249 species have been recorded. Possibly another
100 species will be reported after further studies have been made
there. At least 154 of the species listed in this paper probably breed
in Coahuila. The bird fauna in the State includes species characteristic
of eastern North America and of western North America, species that
range from the Atlantic to the Pacific Ocean, and species found only,
or mostly, in Mexico.
