Identification.
This is the largest species of
Sylvilagus
Gray,
1867
in
Chihuahua
and the only one occurring in the highlands of the Sierra Madre Occidental. It is a large, heavy-bodied rabbit, with a gray-brown coat, and a conspicuous white tail. The belly hair is white (
Chapman et al. 1980
;
Lee et al. 2010
).
Distribution.
From southern
Canada
, through central, eastern
USA
and the Mexican highlands (pine, pine-oak forests) to Central America and northern South America (
Venezuela
and
Colombia
;
Chapman et al. 1980
). Recorded habitats in Chihuahua are sierras, valleys, and arid lands.
Remarks.
Two species of
Sylvilagus
have been recorded
in
Chihuahua
(
López-González and García-Mendoza 2012
): The Eastern Cottontail Rabbit and the Desert Cottontail Rabbit (
Sylvilagus audubonii
(Baird, 1858))
; the former inhabits forested areas (pine and pine-oak forests), and the latter inhabits grassland and desert areas.
