Habits: Found along small rainforest streams at mid-altitudes. Males call during the day from hidden positions on the ground in the immediate proximity of streams (Glaw and Vences 2007). Calls: A rapid series of 31-36 short pulsed notes (Glaw and Vences 2007).

Life History, Abundance, Activity, and Special Behaviors
provided by AmphibiaWeb articles
This species is listed as data deficient because of continuing uncertainties as to its extent of occurrence, status and ecological requirements. Though it occurs in the Réserve Spéciale d’Analamazaotra, its forest habitat is receding due to subsistence agriculture, timber extraction, charcoal manufacture, invasive spread of eucalyptus, livestock grazing and expanding human settlements (Glaw and Vences 2008).

Mantidactylus albofrenatus
provided by wikipedia EN
Mantidactylus albofrenatus is a species of frog in the family Mantellidae. It is endemic to eastern Madagascar near An'Ala and Andasibe.[1][2][3] Common name eastern Madagascar frog has been proposed for it.[1][2]
Description
Adult males measure 19–23 mm (0.7–0.9 in) and adult females 25–27 mm (1.0–1.1 in) in snout–vent length. The legs are short. The tympanum is large in the males, larger than the eye. Males have distinct femoral glands. The toes have rudimentary webbing. The dorsal colouration is brown, forming a distinct dorsolateral colour border with the dark brown flanks. A distinct light stripe runs from the forelimb insertion to (almost) the nostril. The throat is dark grey with a distinct pattern of white spots forming a median row. The hind limbs have dark crossbands.[4]
The male advertisement call is a rapid series of 31–36 short pulsed notes.[3]
Habitat and conservation
Mantidactylus albofrenatus is a terrestrial frog occurring in pristine or only slightly disturbed rainforest at elevations of 850–900 m (2,790–2,950 ft) above sea level. It is often found near streams.[1] Calling males have been found near streams during the daytime.[4] The eggs are presumably laid on land.[1]
It is a locally abundant species, but it is only from two localities and its population is suspected to be decreasing because of ongoing habitat loss and deterioration. It occurs in the Analamazaotra Special Reserve.[1]
