Todirostro Común

Identificación

The common tody-flycatcher is a tiny, big-headed bird, 9.5–10.2 cm (3.7–4.0 in) long, weighing 6.5–6.8 g (0.23–0.24 oz), and with a long, flattened, straight black bill. The upper head is black, shading to dark grey on the nape and dark olive-green on the rest of the upperparts. The usually cocked tail is black with white tips, and the wings are blackish with two yellow wing bars and yellow edging to the feathers. The underparts are entirely yellow. Sexes are similar, but young birds have a greyer upper head, buff wing markings, and paler underparts.<p>Males of this species have a rapid grasshopper-like ticking te’e’e’e’e’e’t call something like a tropical kingbird, and a dawn song consisting of a very fast high tic repeated up to 110 times a minute for minutes on end.

Taxonomía

The common tody-flycatcher was formally described by the Swedish naturalist Carl Linnaeus in 1766 in the twelfth edition of his Systema Naturae under the binomial name Todus cinereus. Linnaeus based his description on the "Grey and Yellow Fly-catcher" that had been described and illustrated in 1760 by George Edwards from a specimen collected in Suriname. The specific epithet cinereum is from Latin cinereus meaning "ash-grey". The common tody-flycatcher is now the type species of the genus Todirostrum that was introduced by René Lesson in 1831.<p>Eight subspecies are recognised:

Distribución y hábitat

It is a very common inhabitant in gardens, shady plantations, second growth and the edges and clearings of forest, although it avoids the dense interior of mature woodland and also arid areas. The common tody-flycatcher is usually seen in pairs, making rapid dashing sallies or hovering to pick small arthropods off the vegetation. It often wags its tail as it moves sideways along branches.

Resident species

Comportamiento

It breeds from sea level to 1,150 m (3,770 ft) altitude, locally to 1,500 m (4,900 ft). Both male and female birds build a pouch nest with a visored side entrance, which is usually suspended from a thin branch or vine 1–5 m (3.3–16.4 ft) high in a tree, though occasionally it can go up to 30 m (98 ft). The female incubates the two usually unspotted white eggs for the 15–16 days prior to hatching.
