Taxonomy and systematics

The narrow-billed tody and the other Hispaniolan tody, the broad-billed (''T. subulatus''), were originally thought to share a recent common ancestor, because the other three todies are each the only one on different islands. However, phylogenetic analysis suggests that the narrow-billed tody descended from the Cuban tody (''T. multicolor'') and the broad-billed tody descended from the

Description

All five members of genus ''Todus'' are very small, chunky, and short tailed. The narrow-billed tody weighs about . Its upperparts are bright green, becoming almost emerald around the white eyes. A white malar stripe separates the face from the carmine red chin and throat. The sides of the neck and breast are deep lead gray; the rest of the breast and the belly are white. The flanks are geranium pink to red. The upperside of the wing is bright green and much of the underwing is sulphur yellow. Its

Distribution and habitat

The narrow-billed tody is resident on Hispaniola and occurs in both countries of the island. It mostly inhabits dense wet jungle and forest between elevations of . It is also found locally at lower elevations, where it overlaps the distribution of the broad-billed tody.

Behavior

Feeding

The narrow-billed tody's diet is almost entirely insects; at least 49

Breeding

The narrow-billed tody makes display flights without vocalizations, in a manner similar to those of others of its

, but includes wing rattling that others do not. Both sexes excavate a nest burrow about deep in an earthen bank. The clutch size ranges from one to four glossy white eggs. Usually one clutch is laid per season, between April and July. Both sexes inclubate the eggs. Pairs separate after the young fledge and do not necessarily mate with each other the next year.

Vocalization

A characteristic narrow-billed tody vocalization is "a two note call, described as ''chip-chee'', accented on the second syllable." They also make a short chatter.
