The black-billed nightingale-thrush (Catharus gracilirostris) is a small thrush endemic to the highlands of Costa Rica and western Panama. Its position in the genus Catharus is somewhat equivocal, but it is apparently closer to the hermit thrush than to the other nightingale-thrushes except the russet nightingale-thrush and/or the ruddy-capped nightingale-thrush (Winker & Pruett, 2006). [2]

It is found in the undergrowth of wet mountain oak forests and second growth, typically from above 1350 m altitude to patches of scrubbery beyond the timberline. The nest is a bulky lined cup constructed 1–5 m high in a scrub or small tree, and the typical clutch is 2 brown-blotched greenish-blue eggs. [3]

This small species is 13.5 to 16 cm (5.3 to 6.3 in) in length and weighs 21 g (0.74 oz). The adult has olive- brown upperparts, a grey crown, paler grey underparts, becoming whitish on the belly, and an olive breast band. Its bill is black.

The juvenile is darker on the head and underparts, has a brown breast band, and the belly is marked with brown. The birds in the Chiriqui mountains of western Panama are slightly more rufous above and paler below than the Costa Rican population, and are sometimes considered as a subspecies, C. g. accentor.

The black-billed nightingale-thrush will normally forage low in vegetation or on the forest floor, alone on in pairs, progressing in hops and dashes with frequent stops. It turns leaf litter in typical thrush fashion seeking insects and spiders, and also eats many small fruits. Despite its habitat, this species is tame and often confiding.

The black-billed nightingale-thrush's song is up to three flute-like tones followed by a jumbled trill, and the call is a high thin seet.

<i>Catharus</i> Genus of birds

The genus Catharus is an evolutionary clade of forest-dwelling passerine birds in the family Turdidae (thrushes), commonly known as nightingale-thrushes. The extant species are widely distributed across the Americas and are descended from a common ancestor that lived 4–6 million years ago. Most of the species are shy of humans, seldom leaving the cover of dense forest vegetation, where their activities are hidden from view. Thus, many fundamental aspects of their biology and life histories are poorly known.

<span class="mw-page-title-main">Wood thrush</span> Species of bird

The wood thrush is a North American passerine bird in the family Turdidae and is the only species placed in the genus Hylocichla. It is closely related to other thrushes such as the American robin and is widely distributed across North America, wintering in Central America and southern Mexico. The wood thrush is the official bird of the District of Columbia.

<span class="mw-page-title-main">Veery</span> Species of bird

The veery is a small North American thrush species, a member of a group of closely related and similar species in the genus Catharus, also including the gray-cheeked thrush, Bicknell's thrush, Swainson's thrush, and hermit thrush. Alternate names for this species include Wilson's thrush and tawny thrush. Up to six subspecies exist, which are grouped into the eastern veery, the western veery or willow thrush, and the Newfoundland veery.

<span class="mw-page-title-main">Hermit thrush</span> Species of bird

The hermit thrush is a medium-sized North American thrush. It is not very closely related to the other North American migrant species of Catharus, but rather to the Mexican russet nightingale-thrush. The specific name guttatus is Latin for "spotted", though historically this species has been given 17 additional species or subspecies names by various authors, now all treated as synonyms.

<span class="mw-page-title-main">Swainson's thrush</span> Species of bird

Swainson's thrush, also called olive-backed thrush and russet-backed thrush, is a medium-sized thrush. It is a member of genus Catharus and is typical of it in terms of its subdued coloration and beautiful, ascending flute-like voice. Swainson's thrush was named after William Swainson, an English ornithologist.

<span class="mw-page-title-main">Grey-cheeked thrush</span> Species of bird

The grey-cheeked thrush is a medium-sized thrush. This species is 15–17 cm (5.9–6.7 in) in length, and has the white-dark-white underwing pattern characteristic of Catharus thrushes. It is a member of a close-knit group of migrant species together with the veery and Bicknell's thrush; it forms a cryptic species pair with the latter. The grey-cheeked thrush is all but indistinguishable from Bicknell's thrush except by its slightly larger size and different song. The two were formerly considered conspecific. Of all the American spotted thrushes, the grey-cheeked has the most northern breeding range.
