متن کاملPopulation size, breeding biology and on-land threats of Cape Verde petrel (Pterodroma feae) in Fogo Island, Cape Verde
Cape Verde petrel (Pterodroma feae) is currently considered near threatened, but little is known about its population size, breeding biology and on land threats, jeopardizing its management and conservation. To improve this situation, we captured, marked and recaptured (CMR) birds using mist-nets over 10 years; measured and sexed them; monitored up to 14 burrows, deployed GPS devices on breeder...
متن کاملA burrowscope for examining petrel nests in burrows
This report describes the development and refinement of a burrowscope that is reliable and robust enough to withstand arduous field conditions crucial for obtaining accurate data on sooty shearwater (Puffinus griseus) burrow occupancy and breeding success. The burrowscope consists of a miniature camera and infra-red lights mounted on a three metre length of hose through which images are project...
متن کامل'hovering' Flight of Wilson's Storm Petrel
Wilson's storm petrel (Oceanites oceanicus) characteristically feeds by ' hovering' over the water surface, but its technique for this is unlike that of other flying vertebrates. The kinematics and aerodynamics of this ' hovering' flight were investigated to determine the possible sources of lift; various nonaerodynamic sources of lift were discounted. It is suggested that the storm petrel soar...
متن کاملUse of burrow entrance flaps to minimise interference to Chatham petrel (Pterodroma axillaris) chicks by broad-billed prions (Pachyptila vittata)
The Chatham petrel (Pterodroma axillaris) is an endangered species, restricted to. a single population on South East Island, Chatham Islands. The key threat to breeding success is loss of chicks as a result of interference by broad-billed prions (Pachyptila vittata) prospecting for burrows for their oncoming breeding season. The effectiveness in decreasing interference using an artificial burro...
