Golden-cheeked Warbler

Setophaga chrysoparia

Nidifica esclusivamente in boschi misti di ginepro-quercia nel Texas centrale. Raramente visto in migrazione. Il maschio ha corona, gola e dorso nero corvino; faccia giallo brillante con una linea nera attraverso l'occhio. Due barre alari bianche; parti inferiori bianche con striature nere lungo i fianchi. Femmina e giovani più opachi con gola pallida, dorso e corona verde-oliva; simile alla Parula gola-nera, ma si noti la linea scura più distinta attraverso l'occhio e l'assenza di sottocoda giallo. Sverna in foreste montane di pino-quercia in Messico e America Centrale. Il canto variabile include diversi trilli e ronzii a diverse tonalità.

Identificazione

The golden-cheeked warbler is very striking due to its bright yellow cheeks that are contrasted by its black throat and back. It is also identified by its unique buzzing song emerging from the wooded canyons where it breeds. Golden-cheeked warblers breed in 33 counties in central Texas and are dependent on ashe juniper (blueberry juniper or cedar) for their fine bark strips used as nesting material.

Areale e habitat

The golden-cheeked warbler can be found in numerous state parks within Texas. These parks include Colorado Bend State Park (SP), Dinosaur Valley SP, Garner SP, Guadalupe River SP, Honey Creek State Natural Area (SNA), Hill Country SNA, Kerr Management Area, Longhorn Cavern SNA, Lost Maples SNA, Meridian SP, Pedernales Falls SP, Possum Kingdom SP, and South Llano River SP.<p>The golden-cheeked warbler is endemic to Texas and Mexico. Their habitat can range from moist, to dry areas around central and southern Texas. The nesting habitat in the further moist realms can be discovered in tall, closed canopy, compressed, mature stands of ashe juniper (Juniperus ashei) trees along with Texas, shin, live, lacey, and post oak trees. In the drier spheres of Texas, golden-cheeked warblers can be found in upland juniper-oak woodlands off of flat topography. They use ashe juniper bark and spider webs to build their nests. Females lay three to four eggs. When migration and winter hits the habitat stays relatively similar: a variety of short-lived evergreen forests with pines between 3,300 and 8,300 feet.<p>Golden-cheeked warblers will only remain in Texas for the breeding season, from March to June. They will migrate with other songbird species along Mexico's Sierra Madre Oriental. By the first week of March, the warblers will return to Texas to breed. During the winter season (November–February), warblers will travel to Guatemala, Nicaragua, Honduras, and Mexico.
