E. hedricki was discovered in 1962, when finding a new species of frog seemed very improbable. Named in honor of Hedrick J. Rivero at age 9, who declared himself assistant to his father and followed him through creeks, caves and mountains during any time of the day or night.
Distinctive features are the pronounced constriction in the back of the head (as if the waist were in the back of the head), a shallow furrow along the middle of the back from between the eyes to near the sacral hump, and the short rounded snout. Other distinguishing but not necessarily exclusive characteristics are: the small eyes, with narrow upper eyelids, the uniformerly granular dorsum, the pair of light, externally concave lines on the back (not too distinct in very dark animals), the blackish throat of males, and the absence of dark streaks along the sides of the snout. The basic dorsal color may be brown or dark gray, almost uniform or with obscure variegation or vermiculations of lighter gray. The males averages 32.8 mm in size, while females averages 34.6.
The Tree Hole Coqui is one of the mountain species. It is an arboreal species that rest in and calls from holes and crevices in tree trunks and branches, often as high 20 or 30 ft. from ground.
The voice of E. hedricki is a resonant "ping, ping, ping". The species may be heard during the day time but by midnight most of the callers have become silent. The voice has not been heard below about 1,000 ft.
Lower elevation forests in the Luquillo Mountains (El Yunque), Cayey Mountain Range and Central Mountain Range. [1]
