The buff-tailed sicklebill (Eutoxeres condamini) is a species of hermit hummingbird from the lower Andes and adjacent west Amazonian lowlands from southern Colombia and northern Ecuador to Peru and Bolivia.[3]

Description

With a total length of 5–6 in (13–15 cm) and weighing 0.28–0.44 oz (7.9–12.5 g), it is a relatively large hummingbird. Males and females are virtually identical, differing only in size (especially wing measurements), with the females being some 20% smaller.[3]

Its upperparts are

rectrices (tail feathers) are white, and there is a naked stripe on top of the head (but this is usually concealed). The most conspicuous features, however, are those the common name refers to: the bill is strongly decurved, and the outer three rectrices on each side are deep buff, best visible from below.[3]

Immature birds have light-tipped

down.[3]

There are two

cline, with an extensive intergradation zone in northern Peru:[3]

  • Eutoxeres condamini condamini (Bourcier, 1851) – northern buff-tailed sicklebill
Colombia and Ecuador. Bill longer, lower belly much streaked
  • Eutoxeres condamini gracilis
    Stolzmann
    , 1902     – southern buff-tailed sicklebill
Central Peru to Bolivia. Bill shorter, lower belly less streaked

The buff outer remiges are the most reliable trait for separating the buff-tailed sicklebill from the only other member of the

Putumayo around Mocoa, Colombia.[4]

Ecology

It is restricted to the undergrowth of

arthropods.[5]

The two white eggs are laid in a nest which is attached to the underside of a leaf, a few yards/meters above ground. In the southern Cordillera Oriental of Colombia, nest construction was observed in July or August, and in the lowlands of Ecuador's Napo Province in January. Birds with enlarged gonads were found in Peru from September to November. Only the female incubates; the incubation period is 16–18 days and the young fledge 22–24 days after hatching. They start to breed when they are 1–2 years old.[6]

Generally fairly common though inconspicuous and easily overlooked, it is considered a species of

IUCN.[1] This species is most easily seen in the mixed habitat of old and young forest and small-scale logging at the Napo River in eastern Ecuador.[7]
