Habitat

The preferred natural habitat of M. boddaerti is forest, at altitudes of 24–2,600 m (79–8,530 ft).^[1]

Description

M. boddaerti changes coloration ontogenetically. Juveniles from Guyana have a brown dorsum with grayish tan bands, with white spots ventrolaterally on anterior ends of the tan bands. The chin and throat are white, with dark brown irregular spots. The venter is tan-colored. Adults are nearly uniform brown dorsally, with traces of bands anteriorly. There is a lateral light tan stripe on the anterior half of the body. The venter is light gray with darker gray smudges on the throat.^[5] Individuals from Brazilian Amazonas measured up to 109 centimetres (3 ft 7 in) in snout–vent length.^[6]

Behavior

M. boddaerti is diurnal and mainly terrestrial, but it will occasionally climb low vegetation.^[1]

Diet

M. boddaerti feeds on young birds, frogs, lizards, and mice.^[4][7] Specimens from Brazilian Amazonas fed mostly on lizards, followed by mammals and frogs.^[6]
