known to occur north of Lobito, Angola however, at least in modern times. H. meadewaldoi had a glossy black coloration overall save for the whitish underwing bases of the primary remiges' inner webs, but this may have not been present in worn plumage which also was duller. Its bill, laterally compressed and with a blunt, lighter tip, and a narrow naked ring around the red eye were reddish orange, and the legs and feet were dark pink with ivory-colored nails. As usual in oystercatchers, it had no hallux and the second and third toes were connected by a small web. The sexes did not differ in color; juvenile birds are unknown but probably had duller bare parts and some greyish-buff fringes to the feathers. The coloration of downy young is likewise unknown; these are generally brownish-grey above with dark striping to provide camouflage against predators such as gulls; considering the dark lava rock habitat of this species, they were probably fairly dark overall and had a dusky belly. Habits The Canary Islands oystercatcher was apparently an all-year resident, and seems to have never bred or even strayed outside the eastern Canaries at least in historic times. Information about its ecology are scant and usually second-hand or inferred from circumstantial information. However, even though conjectural, these informations are consistent as the biology of oystercatchers is not very variable and the species was a conspicuous bird well known to locals. It was called cuervo marino ("sea raven") on Fuerteventura, grajo de mar ("sea chough") on Lanzarote, and corvino ("little raven") on Graciosa. In addition, the local name lapero ("limpet-eater") was also used, possibly on Alegranza. The Canary Islands oystercatcher was in all likelihood a bird of the rocky shore rather than sandy beaches; although it might have been driven from the latter as they were much more utilized by humans – which it tended to avoid. What is known about its feeding habits indicates that it had always been less commonly found in beach habitat. As with all oystercatchers, its diet consisted of small molluscs and crustaceans rather than oysters. Especially the limpets Patella candei, Patella piperata, and Patella cf. ulyssiponensis, as well as the African mussel Perna (perna) picta were favorite prey items. Its vocalizations were given as repeated kvirr or kvik-kvikkvik, and the alarm call peepe-peepe peepe-peepe. The birds appear to have been territorial in the breeding season and vagrant,
