During August-September 2014 and 2015, yachtbased surveys were conducted in the Cape Verde archipelago with the main objective of trying to locate humpback whales Megaptera novaeangliae during the late boreal summer (Berrow et al. 2014). Spring breeding humpbacks in Cape Verde waters are known to have their feeding grounds in the high Arctic (e.g. Wenzel et al. 2009). While these animals have generally left the breeding grounds by mid-May, a number of sightings during the summer months (June- August) have raised the possibility that animals from southern stocks may occasionally reach as far north as Cape Verde (Hazevoet et al. 2011).
Recent data on status and distribution of resident and migrant birds in the Cape Verde Islands are presented, including records of nine taxa new to the archipelago, viz. Ciconia nigra, Ciconia ciconia, Circus macrourus, Falco naumanni, Chlidonias hybrida, Chlidonias leucopterus, Apus affinis, Ptyonoprogne fuligula and Phylloscopus inornatus. Also presented are data on a number of breeding taxa, including the first record of the endemic Cape Verde purple heron Ardea bournei outside Santiago island. The alarming situation of the magnificent frigatebird Fregata magnificens, of which only three individuals remain in Cape Verde, constituting the entire population in the East Atlantic, remains of great concern. Several species of birds of prey are also highly threatened and have already become extinct in some islands. Following its expansion through Northwest Africa and the Canary Islands, Eurasian collared dove Streptopelia decaocto has now also become established in at least three of the Cape Verde Islands.
Dragonflies from the Cape Verde Islands, collected between 1960 and 1989 and kept in institutes in Portugal and Cape Verde, were studied. The Cape Verde collection at the Centro de Zoologia, Instituto de Investigação Científica Tropical, Lisbon, Portugal, includes eight species of dragonflies represented by 279 specimens collected in 1960-61 and 1969-72. The entomological collection at the Instituto Nacional de Investigação e Desenvolvimento Agrário (INIDA), São Jorge dos Orgãos, Republic of Cape Verde, includes four odonate species, represented by 27 specimens, collected in the years 1987 and 1989. Anax tristis Hagen and A. rutherfordi McLachlan, single male specimens of which were collected in Santo Antão, 27 October 1972, are new taxa for the archipelago. Both are tropical migrants of which the nearest known occurrence in continental Africa is more than 1,000 and 1,500 km, respectively, from the Cape Verde Islands. The two collections contain several specimens from new localities within the archipelago, particularly from the islands of Maio and Fogo. Current knowledge of flight season and island distribution are summarized and updated.
Recent data on status and distribution of resident and migrant birds in the Cape Verde Islands are presented, including records of nine taxa new to the archipelago, viz. Ixobrychus sturmii, Botaurus stellaris, Butorides striatus, Circus cyaneus, Porzana pusilla, Fulica atra, Chlidonias niger, Acrocephalus schoenobaenus and Hippolais polyglotta. Also presented are data on a number of breeding taxa, including the first record of the endemic Raso lark Alauda razae outside the islet of Raso. The alarming situation of the magnificent frigatebird Fregata magnificens, of which probably only two individuals remain in Cape Verde, constituting the entire population in the East Atlantic, is highlighted. During the past decade, breeding populations of common moorhen Gallinula chloropus appear to have become well-established on the islands of Santiago and Boavista. Following its expansion through Northwest Africa and the Canary Islands, Eurasian collared dove Streptopelia decaocto has now also colonized the Cape Verde Islands.
Recent data on status and distribution of resident and migrant birds in the Cape Verde Islands are presented, including records of 25 taxa new to the archipelago, viz. Mareca penelope, M. americana, Anas carolinensis, A. clypeata, Pterodroma arminjoniana, Sula dactylatra, Egretta thula, Ardea melanocephala, Hieraaetus pennatus, Porzana porzana, Crecopsis egregia, Porphyrula martinica, Pluvialis apricaria, Calidris fuscicollis, C. bairdii, Gallinago delicata, Larus audouinii, L. atricilla, Streptopelia decaocto, Ceryle rudis, Ptyonoprogne rupestris, Motacilla citreola, Erithacus rubecula, Oenanthe leucopyga and Lanius senator. The current situation of some endemic taxa is discussed, some of which (e.g. Ardea bournei) are critically endangered, while others (e.g. Acrocephalus brevipennis) have been shown to be more widespread than previously known.
Dragonflies (Insecta, Odonata) of São Vicente, Cape Verde Islands : 10 species on a desert island
(2010)
The island of São Vicente, Cape Verde Islands, has no natural and permanent surface fresh water habitats. Surprisingly, with records of 10 species of dragonflies, the island is the most species-rich in the archipelago so far (cf. Aistleitner et al. 2008, this study). Knowledge of Odonata from São Vicente is based on a small number of reports, mostly including single records only (Calvert 1893, Kirby 1897, Lobin 1982, Aistleitner et al. 2008). During a visit to the island in August 2009, AM recorded four species as single adults. Two species were recorded on 26 August 2009, after two days of heavy rainfall which caused extensive temporary waterflows and pools in the main courses of river beds, on the plains, as well as on roads and sports grounds in and around the town of Mindelo.
First record of Straw-coloured fruit bat Eidolon helvum (Kerr, 1792) for the Cape Verde Islands
(2010)
On 8 September 2010, at 9:45 AM, a fruit bat was seen flying at a height of ca. 2 m over the sea off Ervatão, southeastern Boavista, Cape Verde Islands (16º 02’ N, 22º 41’ W). After a while, the animal landed in the beach vegetation. When captured, it did not offer any resistance to being handled and it was taken to the nearby sea turtle station, operated by the NGO Cabo Verde Natura 2000. The bat – which proved to be a female – was placed in an improvised cage made of plastic netting where it eagerly fed on the food provided, i.e. tomato, apple and banana. At 16:00 PM, the following biometric data were taken: head width 31.6 mm, humerus 81.1 mm, ulna 121.2 mm, tarsus 49.7 mm. When restrained for taking body measurements, the bat attempted to defend itself with its mouth.
Based on both stranding and sighting records, recent data on the status and distribution of whales and dolphins in the Cape Verde Islands are presented, including records of four taxa new to the archipelago, viz. Common minke whale Balaenoptera acutorostrata, Dwarf sperm whale Kogia sima, beaked whale Mesoplodon cf. europaeus and False killer whale Pseudorca crassidens. Distribution elsewhere in the tropical eastern Atlantic and some taxonomic issues are discussed.
