Whistling Frog
Eleutherodactylus cochranae

Appearance:
Eleutherodactylus cochranae range in size from about 16 to 20 mm SVL (maximum SVL 21mm in females).  The dorsum can be gray, tan, or gray-brown in color with a light gray pattern that resembles a pair of reversed parentheses. The limbs are brown with variable venter coloration—white to gray, cream, or yellow.  The throat and underside of the thighs are speckled with fine brown spots.  There is a fine, dark line that appears on the midline of the snout.  Toe pads are small.

Habitat: Eleutherodactylus cochranae are usually found in xeric wooded areas. During the day, these frogs may use bromeliads and coconut husk piles as refugiaEleutherodactylus cochranae feed on insects.

Vocalization: The call for the Whistling Frog is a single, rising whistle that is repeated and sometimes followed by 1-3 clicks.  Males usually call from 3 ft. above ground to high in the trees.  Calling generally occurs from before dusk to after dawn, with weak peaks at those times.

Status/Range: Nesting/breeding on St. John, Puerto Rico and all Puerto Rican islands except Mona and Monito, St. Thomas and its adjacent islands, and all British Virgin Islands except Anegada.
