Candelita Aliblanca

Identificación

The painted redstart is the largest species of Myioborus, measuring 5.1–5.9 in (13–15 cm) in length, 8.3 inches (21 cm) in wingspan and having a weight of 0.3–0.4 oz (8.5–11.3 g).<p>The sexes are the same in plumage, though males average slightly larger than females. The adult is mostly black, with a bright red lower breast and belly, large white wing patches, white outer tail feathers and white crescents below its eyes. The bill and legs are blackish.<p>The juvenile painted redstart lacks the red belly and glossy black plumage of the adult. It is brownish-gray overall, with a paler belly and undertail coverts, and a pale cream or buff tinge to its wing patches. The young have a deep yellow-orange mouth lining.<p>Painted redstarts are unusual amongst birds, and especially amongst warblers, in that the female is capable of singing just as well as a male, and during spring courtship a pair will often bond by singing together.

Taxonomía

When he first described the species in 1829, naturalist William John Swainson assigned it to the genus Setophaga — the same genus as that of the American redstart — where it remained for nearly a century and a half, though one naturalist placed it in the Old World flycatcher genus Muscicapa during that time. By the mid 1960s, researchers recommended that it be moved to its current genus, Myioborus, based on various similarities with the other whitestarts. The painted redstart is the sister taxon to all the other species in the genus Myioborus.<p>There are two subspecies, which differ only slightly in appearance:

Distribución y hábitat

Painted redstarts are common in open oak woodlands and canyons at heights between 1,500–2,500 m (4,900–8,200 ft) in Central America and Mexico, ranging as far north as the Madrean sky islands and Mogollon Rim in Arizona and New Mexico and Big Bend National Park in Texas; they are thought to be wholly insectivorous. During the summer and winter, these birds may venture as far south as Nicaragua. In 2010, a painted redstart was found further north in California than had ever been recorded, in Auburn, CA, east of Sacramento. In 2013, one was observed in Berkeley, CA.
