EX
Canarian Oystercatcher Haematopus meadewaldoi

Justification
This species was found in the eastern Canary Islands, but is now Extinct due to overharvesting of its invertebrate prey. It was last collected in 1913, and locally reported to be absent by the 1940s.

Taxonomic note
Hockey (1982) showed that this taxon was distinct from African Black Oystercatcher H. moquini.

Distribution and population
Haematopus meadewaldoi was endemic to Fuerteventura, Lanzarote and their offshore islets in the Canary Islands, Spain (Collar et al. 1994). It was last collected in 1913 and locally reported to have become extinct by the 1940s (Collar and Stuart 1985). It is now considered extinct because extensive surveys in the mid-1980s failed to find any evidence of the species's survival, despite four convincing reports (two from Tenerife and two from Senegal) between 1968 and 1981 (Collar et al. 1994).

Ecology
It inhabited the coastal zone where it foraged for invertebrates; its ecology was likely to have been typical of the genus.

Threats
Its decline was probably a result of overharvesting of intertidal invertebrates and disturbance by people (Hockey 1987), although predation by rats and cats has also been implicated (Collar and Stuart 1985).
