Description
The violet sabrewing is the largest hummingbird of Mexico and Central America. It is 13 to 15 cm (5.1 to 5.9 in) long and weighs 9 to 12 g (0.32 to 0.42 oz). Both sexes have a black bill, though those of subspecies C. h. mellitus are longer than the nominate's. Males of the nominate subspecies have a dusky crown with a bluish green gloss. Their nape and upper back, face, and underparts are metallic violet blue that is somewhat bluer on the belly. Their lower back and uppertail coverts are metallic green. Their central tail feathers are bluish green to bluish black and the rest blackish with wide white tips. Females have a dusky crown and metallic green to bronze green upperparts with a more bluish green rump. They have a violet blue throat. Their underparts are mostly gray with a whiter belly and metallic green spots along the sides and green undertail coverts. Their central tail feathers are bluish green and the rest blacker with wide white tips.[5][6]
Males of subspecies C. h. mellitus have more green on their upper parts than the nominate and almost entirely violet underparts with no blue on the belly. Female's upper-parts have a coppery tinge and their throat is violet.[5]
Distribution and habitat
The nominate subspecies of violet sabrewing is found from the Mexican states of
Behavior
Movement
The violet sabrewing is mostly sedentary, but individuals frequently move to lower elevations after the breeding season.[5]
Feeding
The violet sabrewing feeds on nectar primarily by
Breeding
The violet sabrewing breeds during the local rainy season, which ranges from June to September in Mexico and May to November in Costa Rica. In the latter country they may raise two broods. Males court females by singing in leks, typically in the understory or at the forest edge. The nest is a cup of moss cemented with spiderwebs and lined with fine fibers. In Costa Rica it is often built above a ravine or stream, on a horizontal branch 1 to 6 m (3 to 20 ft) above the ground. The female incubates the clutch of two eggs for 19 to 22 days and fledging occurs 22 to 24 days after hatch.[5][7]
Vocalization
The violet sabrewing's song has been described as "cheep tsew cheep tik-tik tsew cheep ..., high-pitched, piercing and ventriloquial" and as "varied, loud, sharp chipping and warbles, often punctuated with fairly shrill, slightly explosive notes". Its calls are "high, sharp chippering", "prolonged, hard chipping", and "single sharp chips given in flight."[5][7]
