Paruline de Fernandina

Teretistris fernandinae

Un résident grégaire des enchevêtrements denses et des fourrés dans des habitats par ailleurs ouverts ; on ne le trouve ni en forêt dense ni dans les mangroves. Le corps gris contraste fortement avec sa tête jaune, mais noter que certains oiseaux ont également du jaune sur la poitrine. Les Parulines protonotaires sont quelque peu similaires, mais sont principalement jaunes dessous avec un dos vert (non gris). Les Parulines des pins ont un dos vert, des barres alaires blanches et sont généralement plus largement jaunes dessous. Le chant est une série de notes râpeuses et bourdonnantes. Les cris sont similaires au chant, mais sont donnés de manière isolée ou sans motif.

Identification

The yellow-headed warbler is about 13 cm (5.1 in) long and weighs 6 to 18.5 g (0.21 to 0.65 oz). Its entire head is yellow, with an olive tinge on the crown and nape. Its upperparts are gray and its underparts a lighter grayish white.

Taxonomie

The yellow-headed warbler shares its family and genus with the Oriente warbler (T. fornsi). They were originally placed in the New World warblers (Parulidae) but phylogenetic studies of nuclear and mitochondrial DNA led to reassessment of several genera and in 2017 the Cuban warblers were moved to their own family. Their closest relatives are the four members of family Spindalidae, the yellow-breasted chat (Icteria virens), and the New World blackbirds of family Icteridae.<p>The yellow-headed warbler is monotypic.

Répartition et habitat

The yellow-headed warbler is found in far western mainland Cuba, Isla de la Juventud (Isle of Pines), and the nearby Cayo Cantiles. It inhabits all available forest types as long as they have a relatively undisturbed understory, and also scrubby thickets in drier areas. In elevation it ranges from lowlands to high mountains.

Resident species

Comportement

The yellow-headed warbler is a year-round resident throughout its range.<p>The yellow-headed warbler forages from the ground to the forest mid-level, gleaning rocks and foliage for insects and other invertebrates. It is also believed to take small lizards. It often forages in flocks.<p>The yellow-headed warbler's breeding season is from March to July, with eggs laid in April and May. It makes a cup nest of grass, rootlets, and other plant fibers and usually places it fairly low in a bush, vine, or sapling. The clutch size is two or three eggs. The incubation period and time to fledging are not known.<p>The yellow-headed warbler's song is "a series of buzzy grating notes interspersed with sweeter, more musical notes". Its calls include "a rapid, high-pitched, staccato chattering" and "various other buzzy and grating notes".
