- Icterus gularis
Identification
Adult, sexes virtually identical
- Large, heavily built (largest oriole in the USA)
- Mostly orange and black
- Very deep-based bill
- Straight culmen
- Pale flash at base of lower mandible short
- Black bib "attaches" to corner of bill
- Black lores
- Black tail and mantle
- Black wings
- Lesser coverts same color as body
- tip of greater coverts, base of primaries and some feather edges white
Immature (1st basic plumage) is similar to adult but:
- Less strongly orange
- Mantle often greenish or greenish-greyish
- Lesser coverts with white tips producing a second wing bar
Distribution
North and Central America: found from extreme southern Texas and north-eastern Mexico south to Nicaragua.
Taxonomy
Polytypic. Consists of six subspecies. [1]
- I. g. tamaulipensis:
- I. g. flavescens:
- Coastal south-western Mexico (Guerrero)
- I. g. yucatanensis:
- I. g. gularis:
- Arid tropical southern Mexico (Oaxaca) to Guatemala and El Salvador
- I. g. troglodytes:
- I. g. gigas:
Habitat
Nests in open woodlands.
Behaviour
Breeding
Seasonally monogamous and may be for life. They are almost always seen in pairs.
Nest is a very long woven pouch, attached to the end of a horizontal tree branch. Nest building starts as early as March usually producing one brood per season. However, more southerly populations can produce a second brood. In the event that they brood a second time, a second nest is always built.
Diet
This bird forages high in trees, sometimes in the undergrowth. They mainly eat insects and berries.
Flight
Swift, strong flight on rapid wing beats.
