Distribution
Found from south Mexico south to Panama and Colombia
Locally common in parts of its range.
Taxonomy
Formerly considered conspecific with Southern Emerald Toucanet under the name Emerald Toucanet. Gill and Donsker further split this species into Wagler's Toucanet, Emerald Toucanet, and Blue-throated Toucanet (caeruleogularis including maxilliaris and cognatus).
Subspecies
Clements recognizes 8 subspecies in four groups[2]:
- Wagler's Toucanet:
- A. p. wagleri - in Sierra Madre del Sur of south west Mexico (Guerrero and south-western Oaxaca)
- Emerald Toucanet:
- A. p. prasinus - in south east Mexico (Veracruz, adjacent San Luis Potosí and Oaxaca)
- A. p. warneri - in the mountains of south east Mexico (Sierra de Los Tuxtlas in southern Veracruz)
- A. p. virescens - southeastern Mexico, Guatemala, Belize, western El Salvador, Honduras, and northern Nicaragua
- A. p. volcanicus - in eastern El Salvador (Volcán San Miguel)
- Blue-throated Toucanet:
- A. p. caeruleogularis - Highlands of western Panama (Chiriquí to Coclé) (includes maxillaris according to IOC)
- A. p. maxillaris - Highlands of Costa Rica and western Panama
- Violet-throated Toucanet
Habitat
Open woodland and humid forest.
Behaviour
Diet
Their diet consists mostly of fruit, but some insects, lizards, and bird eggs are also taken. Forages usually singly, sometimes in groups.
Breeding
Breeding generally from March to July, locally starting in February and lasting to November. They nest in an unlined cavity in a tree; 3-4 white eggs are laid and incubated by both sexes for 14–15 days. Both parents care for the young which fledge after about 6 weeks.
