Introduction

These hummingbirds are found in the eastern Andes of Colombia, Ecuador and Peru. The Black-throated Hermit is similar in appearance to the Reddish Hermit (P.ruber), but can be distinguished by their prominent dark brown throat and whitish undertail-coverts. Black-throated Hermits are understory species, and inhabit lowland rainforest as well as more open habitats such as plantations and swamp forest. The nectar of flowering plants such as Costus, Aechmea, Palicourea and Drymonia make up the diet of these hermits, as well as small arthropods.

Field Identification

8–9 cm. Very similar to P. ruber, but easily distinguishable by prominent dark brown throat and whitish undertail-coverts. Male has a more intensely-coloured throat, shorter wings than female (not regularly in race riojae), and, as adult, narrower tail feather margins. The central rectrices are usually rounded, but pointed ones also occur. Dark feathers on the cinnamon-red breast, forming a dark patch or even a band, are regularly found in males. Race riojae is significantly larger than nominate.

Systematics History

Editor's Note: This article requires further editing work to merge existing content into the appropriate Subspecies sections. Please bear with us while this update takes place.

One of the small hermits sometimes separated in genus Pygmornis. Frequently considered conspecific with P. longuemareus, but morphological characters indicate that closest relationship is to P. ruber and P. stuarti (which see). Other close relatives are P. striigularis and P. griseogularis. Two subspecies recognized.

Subspecies


SUBSPECIES

Phaethornis atrimentalis atrimentalis Scientific name definitions

Distribution

E Andes of Colombia, Ecuador and N Peru (Loreto).

SUBSPECIES

Phaethornis atrimentalis riojae Scientific name definitions

Distribution

foothills of C Peru (San Martín S to Pasco).

Distribution

Editor's Note: Additional distribution information for this taxon can be found in the 'Subspecies' article above. In the future we will develop a range-wide distribution article.

Habitat

Understorey of lowland rainforest, in particular at edges, second growth areas, zones transitional to more open habitats, plantations, swamp forest. Usually in lowlands but recorded in Andes S of Marañón Valley to 1200 m.

Movement

No information available. Presumably sedentary.

Diet and Foraging

Nectar of flowering plants like Costus, Aechmea, Palicourea, Drymonia, Gurania, Pitcairnia, as well as small arthropods.

Sounds and Vocal Behavior

Song is a high-pitched phrase repeated incessantly without pauses between phrases, at a rate of c. 1 phrase per 4–6 seconds. Phrase typically comprises several evenly-spaced single notes followed by two more rhythmic notes e.g. “tsee ... tsee ... tsee ... tsee .. tseeetew”. Call a high-pitched “pseep!”, usually given in flight.

Breeding

No nest yet described. Data on gonadal activity indicate breeding in Jul and Nov (Peru), and Sept (Ecuador).
Not globally threatened. CITES II. Present in Río Nambi Reserve, Nariño, and Amacayacu National Park, S Amazonas (Colombia); also recorded near Tingo Maria (C Peru).
