The Saint Lucia Warbler or Lucia Warbler ( Setophaga delicata ) is a Singvogelart from the family of Warblers (Parulidae). He is on the island of St. Lucia in the Lesser Antilles endemic .
features
The Saint Lucia wood warbler reaches a body length of 13.5 cm and a weight of 5.3 to 8.2 g. The wing length is 54 to 57 mm and the tail length 59 to 54 mm. The forehead, a short, narrow lateral crown stripe and the reins are black. The short, wide stripe above the eye and a spot below the eye are light yellow. The rest of the head and the top are purely bluish gray. The upper wings are darker. The large and middle wing covers have white tips and two white wing bands. The three outer tail feathers are broadly white. The throat and the underside to the middle of the abdomen are light yellow. The lower abdomen and the tail-coverts are white. The iris is black. The legs are dark grayish-flesh-colored. The Saint-Lucia wood warbler differs from the closely related Antilles wood warbler by its lighter plumage, by its bluer upper side, by the lighter yellow underside and the pure yellow color of the face. The sexes look the same. The juvenile birds are apparently undescribed, presumably they resemble the young birds of the Antilles wood warbler.
Systematics
The Saint Lucia wood warbler was described by Robert Ridgway as Dendroica delicata in 1883 . In a revision published in 2010, the genera Dendroica and Setophaga were synonymous as they do not differ genetically from one another. Since Setophaga was established by William John Swainson in 1827 and Dendroica in 1842 by George Robert Gray , the use of the first genus has priority.
The Saint Lucia wood warbler and the Barbuda wood warbler ( Setophaga subita ) were long considered subspecies of the Antilles wood warbler ( Setophaga adelaidae ). A study published in 1998 came to the conclusion that the degree of genetic differentiation is so high that a species status can be supported.
Vocalizations
The singing is similar to that of the Antilles forest singer, but is more melodic. The reputation is similar to that of the Antilles wood warbler.
Habitat and way of life
The Saint Lucia wood warbler inhabits montane rainforests. The food consists mainly of insects and other arthropods and is collected by pecking. Compared to the Antilles wood warbler, which is more likely to be found at higher altitudes, the Saint Lucia wood warbler mainly forages at lower altitudes and often in the undergrowth. Couples stay in the same territory all year round. No information is available about reproductive behavior.
status
The Saint Lucia wood warbler was included in the IUCN Red List in 2004 in the “ Least Concern” category. The population is estimated at 10,000 individuals and viewed as moderately abundant. In the 20th century there were noticeable fluctuations in the population, currently the population trend is considered stable.
