The Fuerteventura Chat ("Saxicola dacotiae") formally known as Canary Islands Chat due to its once widespread distubution on the islands is a small
passerine birdthat was formerly classed as a member of the thrush family Turdidae, but is now more generally considered to be an Old World flycatcher, Muscicapidae. It, and similar small European species, are often called chats. It is an all-year resident bird, today only found on Fuerteventurain the Canary Islands, where it is known as "caldereta".
This species has for some time been included in the "Common Stonechat" ("Saxicola torquata"), but it is well distinct; it is in all probability an insular derivative of ancestral
European Stonechats that diverged some 1-2 mya, approximately during the Early Pleistocene(Wink "et al." 2002).
Generally, it appears somewhat intermediate between the closely related European Stonechat, and the
Whinchat, and its body size and shape is reminiscent of a lithe European Robin. Its upperparts are generally colored like in the Whinchat, but more contrasted, dark brown with a blackish head and back streaks. It has a purer white superciliumreaching behind the eye and white neck sides, and a light orangey-chestnut breast becoming duller and paler on the underside towards the whitish belly. The rump and tail are dark, the latter with a white pattern visible in flight. There is also a white wing band. The female is similar to a washed-out version of the male, with a brown, black-streaked head and no white neck patches.
The male has a ticking call like a pebble hitting another, and a high twittering song like a European Stonechat.
This species is highly faithful to good habitat. Its main occurrence and only breeding habitat is in "barrancos", ravines and rocky slopes with fairly sparse (30-50% open ground), shrubby vegetation (Illera "et al.", 2006). Although they sometimes also venture into more open and
aridareas such as "malpaís" (old lavaflows with resurgent vegetation), the species prefers copses of palm trees and shrubs (Álamo Tavío 1975) such as the aulaga " Launaea arborescens", the saltwort " Salsola vermiculata" and the boxthorn" Lycium intricatum" (BirdLife International 2004). Males sing from exposed perches, from where the birds also like to hunt insects on the wing; occasionally, they venture into fields or gardens for feeding. Completely open habitat appears only to be utilized when gathering food for their young (BirdLife International 2004).
Laying 4-5 eggs per clutch and incubating for 13 days, it usually manages to raise 2 clutches of young per year.
This species is now considered Endangered, as construction, mainly
tourism-related, encroaches upon the best habitat (Illera "et al.", 2006). The population is hard to estimate, but most probably between 1.300 - 1.700 mature birds (BirdLife International 2004), and recognizably declining for some time already. In particular, heavy land clearance has occurred more recently on the Jandíapeninsula, isolating the local subpopulation and making it vulnerable to adverse effects of small population size. Desertification, exacerbated by grazing goats and locally sinking water tables, also contributed to habitat loss; feral cats and Black Rats prey on the species and especially its eggs and young. A conservation action plan exists for this species since 1999 (BirdLife International 2004); due to its fairly high reproductive rate, if enough habitat is secured and predators are kept at bay, the species should be able to hold its own.
The Chinijo Chat,
subspecies"murielae" from the Chinijo Archipelagonear Lanzarote, became extinctin the early 20th century, as usually claimed mainly due to deteriorating habitat quality but perhaps more due to persecutions of introduced predators. Peculiarly, the species was not reported to inhabit Lanzarote itselfVerify source|date=July 2007.
