2018–2019, Northern Ireland’s lowland wet grasslands saw a 73% decline in their breeding wader populations, from 1,296 to 354 pairs across 74 surveyed sites. 18.07.22 Papers Transatlantic spread of highly pathogenic avian influenza H5N1 by wild birds from Europe to North America in 2021 Author: Published: 2022 Highly pathogenic avian influenza was detected in poultry and a free-living gull in Newfoundland and Labrador, Canada, in 2021, raising concerns about the potential for a new outbreak and questions about the likely origins of the virus. 11.07.22 Papers View this paper online Urban and coastal breeding lesser black-backed gulls (Larus fuscus) segregate by foraging habitat Author: Published: 2022 A collaboration between BTO, Natural England and University of Exeter researchers used GPS-tracking technology to compare the movements and habitat use of Lesser Black-backed Gulls breeding at neighbouring coastal and urban colonies in Cumbria, northern England. The study found that the distance birds covered making foraging trips and the size of their 'home ranges' – the area that an individual bird uses on a daily basis during foraging, breeding and roosting activities – differed between the urban and coastal colonies and revealed a marked segregation in habitat choice. 11.07.22 Papers View on journal website Breeding ground temperature rises, more than habitat change, are associated with spatially variable population trends in two species of migratory bird Author: Published: 2022 BTO research has examined the effects of climate change and habitat loss on the population trends of Willow Warbler and Chiffchaff. These closely related songbirds, tricky to distinguish by eye, share breeding grounds across the UK but migrate to different wintering grounds. While Chiffchaffs mainly migrate to south-west Europe and north-west Africa, with a small number remaining in the UK, Willow Warblers head across the Sahara to the humid zone in central Africa. 03.07.22 Papers View on journal website Relative roles of static and dynamic abiotic conditions as drivers of foraging behaviour in breeding Sandwich Terns Author: Published: 2022 New research involving BTO used GPS tagging to examine Sandwich Tern foraging behaviour during the breeding season. Like other seabirds, Sandwich Terns are so-called ‘central place foragers’ while they are incubating eggs and feeding chicks, shuttling to and from their nest site in search of food. However, successfully finding food on each trip away from the nest requires navigating a continually changing marine environment and relocating moving prey. 30.06.22 Papers A 30,000-km journey by Apus apus pekinensis tracks arid lands between northern China and south-western Africa Author: Published: 2022 The Swift is widely distributed with a cross-continental breeding range spanning Europe and large parts of Asia and north Africa. Until recently, Swift migration research has focused on populations which breed in Europe and north-western Africa (the apus subspecies), leaving the migration of birds breeding throughout Asia (the pekinensis subspecies) shrouded in mystery. 29.06.22 Papers View on journal website Definition of Favourable Conservation Status for Great Cormorant, Phalacrocorax carbo Author: Published: 2022 23.06.22 Papers Other reports Access via Natural England Pagination First page First Previous page Previous … Page 24 Page 25 Page 26 Page 27 Page 28 Page 29 Page 30 Page 31 Page 32 … Next page Next Last page Last
