Whitestart

The genus Myioborus was introduced in 1865 by the American naturalist Spencer Baird with Setophaga verticalis d'Orbigny & Lafresnaye, 1837, as the type species. This taxon is now considered to be a subspecies of the slate-throated whitestart (Myioborus miniatus).^[2][3] The genus name combines the Ancient Greek μυια/muia, μυιας/muias meaning "fly" with -βορος/-boros meaning "-devouring".^[4]

The stronghold of the whitestarts is northern South America, although a few species range along the Andes as far south as north-western Argentina, while others range north through Central America and as far north as the United States, in the case of the painted whitestart. Most species are restricted to mountain forest and woodland. The ancestral Myioborus warblers, together with those in the genus Basileuterus seem to have colonised South America early, perhaps before it was linked to the northern continent, and these two genera provide most of the resident warbler species of that region.

Whitestart is the name used for all species in this genus by the International Ornithological Congress,^[5] while the Clements checklist, and the American Ornithological Society's North and South American Classification Committeess use "redstart".^[6][7][8] Myioborus species are not closely related to the various species called redstarts in the family Muscicapidae or to the American Redstart.

The genus contains 12 species:^[5]

Most whitestarts are 13–13.5 cm (5.1–5.3 in) long with dark grey or dark olive-green upperparts, except for the white outer tail feathers which are frequently spread in display. Adults have brightly coloured red, orange or yellow bellies. Many species have contrasting black, rufous or yellow caps or distinctive facial patterns, often with white or yellow "spectacles" around the eye.

The painted whitestart, the most northern form, is larger (15 cm (5.9 in) long) and has a different plumage pattern, song and behaviour from the other whitestarts. It is also the only species which is partially migratory, and it could perhaps be placed in a separate genus.

The sexes are similar, as with most resident tropical warblers, since they pair for life, and have little need of sexual dimorphism, unlike many migratory species where the males need to reclaim territory and advertise for mates each year.

The whitestarts are resident in mountain (including tepui) forest, woodland and shrub, where they feed on insects, sometimes as part of a mixed-species feeding flock.
