The Grey-Chinned Hermit (Phaethornis griseogularis) is a species of bird hummingbird in the family Trochilidae. It is found in Brazil, Colombia, Ecuador, Peru and Venezuela.
Taxonomy and systematics
The South American Classification Committee (SACC) of the American Ornithological Society, the International Ornithological Committee (IOC), and the classification of Clements assign three subspecies to the Grey-Chinned Hermit, designated P. griseogularis, P. g. zonura, and P. porcullae Birdlife International’s Handbook of the Birds of the World eventually relegated the species to “porcula hermit” (P. porcullae).
Description
Designated P. griseogularis (Grey-Chinned Hermit ) and P. g. The subspecies Zonora is the gray-chinned hermit, 8 to 10 cm (3.1 to 3.9 in) long. Males weigh 1.8 to 2.5 g (0.06 to 0.09 oz) and females weigh 1.9 to 3 g (0.07 to 0.11 oz). PG porcullae is about 10.5 cm (4.1 in) long and weighs about 2.5 g (0.09 oz). It also has longer wings than the other two subspecies.
All three subspecies typically have greenish upperparts, a cinnamon-red rump, and dark tail feathers with white tips. Males have a gray throat and cinnamon-red underside, often with a black chest stripe. Males are lighter than PG zonura nominate, with gray underparts and more curved bills. PG porcullae is lighter than the other two subspecies and has more white on the tail. The females of all three subspecies are lighter versions of the males.
Distribution and accommodation
PG griseogularis occurs in the eastern Andes from southern Colombia to eastern Ecuador through northern Peru to the San Martin Department and on several isolated mountain ranges in southern and southeastern Venezuela and adjacent northern Brazil. A few records exist in the western Andes of Colombia. PG Sonora occurs in the Maran River Valley of northern Peru, in eastern Cajamarca and adjacent Amazonas departments. PG porcullae is found in the western Andes of Luja Province in southwestern Ecuador, and the departments of Tumbes, Piura, and Lambayeque in northern Peru.
The habitat preferences of gray hermit subspecies vary somewhat, but the common characteristic is dense growth, whether under cloud forest, secondary forest, or forest edges. PG griseogularis grows in the gallery forest.
It is usually found between elevations of 600 and 1,800 meters (2,000 and 5,900 ft) but below 400 meters (1,300 ft) in eastern Colombia, up to 2,200 meters (7,200 ft) in Peru, and from 0 to 90 ft… PG Zonora prefers dry forest. It also typically occurs between 600 and 1,800 meters (2,000 and 5,900 ft). PG portcullis inhabits humid forests and moist areas in otherwise seasonally dry forests. In elevation, it ranges from 400 to 1,600 meters (1,300 to 5,200 ft) in Peru and 900 to 2,000 meters (3,000 to 6,600 ft) in Ecuador.
Feed
The Grey-Chinned Hermit subspecies P. g. griseogularis and P. g. Sonora, like other hermit hummingbird Varieties, is known to be a “trapline” feeder, visiting a circuit of flowering plants for nectar. They also eat small arthropods. It is believed that the strategy and diet of eating pork in PG are similar.
Breeding
Grey-Chinned Hermit are known to congregate at lakes for at least part of the year. The breeding season of the subspecies is not well defined, but P. g. griseogularis includes Oct., p. Zonora includes March, and PG. porcullae appears to spawn at least from January to June. The only described nest is that of PG. The porcullae was a cup made of moss, seed pods, and other plant material suspended from the underside of a long drooping leaf. There were two eggs in it, both hatched. The nests of the other two subspecies are considered identical.
To Give Voice
The songs of P. griseogularis and P. g zonura are “high-pitched series of notes repeated continuously without pause between phrases… multiple, evenly spaced, slightly rising, more complex warbles after one note. For example ‘tsi … tsee … tseeé … tseotsetsee'” is their call “an explosive ‘tseek!’ Which is mostly given in flight.
Cool Facts of Grey-Chinned Hermit
1. PG’s porky song structure is similar to that of other subspecies, but its “notes purer and louder”.In addition to vocalizations, the species also has an audible wing call or call.
2. The IUCN follows the HBW classification and thus treats the hermits of “Grichand” and “Perkla” separately.
3. The organization assesses both as Least Concern, although the population size of neither is known and both are believed to be declining.
4. The named subtypes are considered reasonably common, but the relatively small range of pg.
5. Zonora “may cause future concern”. PG portcullis is also described as “fairly common” but also has a limited range. It is found in many protected areas.
