The Canary Islands stonechat (Saxicola dacotiae), also known as the Fuerteventura stonechat or Fuerteventura chat, and formerly known as the Canary Islands chat due to its once widespread distribution on the Canary Islands, is a sedentary resident bird found only on the island of Fuerteventura where it is known as the Caldereta.

Taxonomy

The Canary Islands stonechat is a small

mya, during the Early Pleistocene
(Wink et al. 2002).

Description

The Canary Islands stonechat is intermediate in appearance between the European stonechat and the whinchat; its body size and shape reminiscent of a lithe European robin. Its upperparts are generally coloured as the whinchat, but more contrasting, dark brown with a blackish head and back streaks. It has a purer white supercilium reaching 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.

Ecology

This Canary Islands stonechat is highly faithful to good

(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 utilised 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 two clutches of young a year.

Conservation status

The extinct sub-species

This Canary Islands stonechat 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 1300 and 1700 mature birds (BirdLife International 2004), and recognisably in decline. In particular, heavy land clearance on the Jandía peninsula is 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, has also contributed to habitat loss. Feral cats and black rats prey on the eggs and young. A conservation action plan has existed 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, it should be able to hold its own.

The Chinijo chat,

extinct in the early 20th century. Usually claimed as mainly due to deteriorating habitat quality, the extinction may be more due to the effect of introduced predators. It was only reported to inhabit two offshore islands (Montaña Clara and Alegranza).[2]
