Movement The mountain avocetbill is sedentary throughout its range.
Feeding The mountain avocetbill forages up to above the ground. It feeds on nectar both while hovering and by clinging to flowers; it sometimes "robs" nectar by piercing the base of a flower. Its diet is not known in detail, but it has been recorded feeding at flowers of the families
Ericaceae,
Onagraceae,
Rubiaceae,
Lobeliaceae, and
Campanulaceae. It also feeds on small insects caught by sallies from a perch.
Breeding The mountain avocetbill's breeding
phenology has not been described. It is believed to be
polygynous like most other hummingbirds.
Vocalization The mountain avocetbil's vocalizations are not well known but do include "a series of descending thin whistles, reminiscent of a
piculet:
wsee wsee wsee wsee." ==Status==
