Abstract Estimating population sizes in the heavily traded grey parrots of West and Central Africa would provide insights into conservation status sustainability harvests. Ideally, density estimates be derived from a standardized method such as distance sampling, but survey efforts are hampered by extensive ranges, patchy distribution, variable abundance, cryptic habits high mobility well logistical difficulties limited resources. We carried out line transect sampling alongside simpler...
Abstract Populations of Psittacidae are endangered by habitat loss and the international pet market. The grey parrot ( Psittacus erithacus ) is among most traded species, yet little known about densities their variability in time space. population parrots on island Príncipe (Gulf Guinea) was estimated with distance sampling, both pre‐ postbreeding seasons. Abundance related to a range features using generalized additive models. Densities averaged 48 ± 3 SE individuals km −2 prebreeding 59 4...
The Tinhosas islands, in São Tomé e Príncipe, host the most important seabird breeding colony Gulf of Guinea, but information on its conservation status was hitherto unpublished or anecdotal, last assessment having been performed 1997. A two-day expedition to islands undertaken estimate seabirds 2013. Four five species known breed namely Brown Booby Sula leucogaster, Sooty Tern Onychoprion fuscatus, Noddy Anous stolidus and Black minutus, occur Tinhosas. decrease 80% numbers, possibly due...
Abstract Effective methods for monitoring animal populations are crucial species conservation and habitat management. Motion‐activated cameras provide an affordable method passively surveying presence across the landscape but have mainly been used studying large‐bodied mammals. This paper explores relative abundance preferences of red squirrels ( Sciurus vulgaris ) in coniferous forests using live trapping. The study was conducted two (Newborough Pentraeth) on Anglesey, North Wales, with a...
Abstract Although both the grey parrot Psittacus erithacus and recently recognized timneh are categorized as Endangered because of harvest for pet trade loss habitat, latter has a much smaller range may be largely restricted to few stronghold areas. In March–April 2018 we surveyed total 114 hours in around one these presumed strongholds, large well-protected Gola Rainforest National Park, Sierra Leonean portion Transboundary Peace Park. Timneh parrots were encountered at rate 0.1 groups/h...
Abstract Information on seasonal changes in waterbird numbers coastal East Africa is limited, but crucial for estimating global flyway populations and targeting conservation efforts. The Sabaki River Mouth an important site waterbirds the region. We counted at monthly from April 2004 to February 2005. Our counts confirmed importance of vulnerable Madagascar Pratincole Glareola ocularis Saunders's Tern Sterna saundersi, with 3% 1%, respectively, hosted. detected internationally (>1%...
Abstract While populations of the Endangered Grey Parrot Psittacus erithacus have collapsed across its range, species remains remarkably abundant on island Príncipe, Gulf Guinea. We examine how aspects ecology interplay with local environmental conditions, to inform conservation strategies for this and other large parrots. On parrots breed in trees common species, nest densities (42 ± 34 km −2 ) greatly exceeding those any comparably sized parrot. Productivity is high (1.9 chicks per...
Introduced grey squirrels (Sciurus carolinensis) cause native red squirrel vulgaris) decline via resource competition (Wauters, Gurnell, Martinoli, & Tosi, 2002) and carry squirrelpox virus (SQPV). Infection is sporadically transmitted to spreads within the population—precipitating disease. Sainsbury et al. (2020) assert that UK mainland reintroductions cannot be justified in light of international guidance translocations will fail because SQPV. They suggest animal suffering result control...
Blainville's beaked whale Mesoplodon densirostris is one of the most widely distributed members family Ziphiidae (the whales). However, its exact distribution in many parts world remains unknown. On 24 November 2004, partly skeletonised carcass an adult male was found on a beach north Sabaki River Kenya (03°09′ S, 40°08′ E). This first confirmed record for this species continental East Africa, and contributes to our knowledge western Indian Ocean.
