“…In fact, these were predicted to occur in mangrove areas in coastal zones, because of the similar climatic features of mangroves and the neighboring rainforests. Cerrado and open areas taxa had SDMs consistent with their known habitat affinity [ 91 – 93 ]. For conservation purposes, models that estimate the full niche requirements are preferred [ 34 ].…”

Delimiting priority areas for the conservation of endemic and threatened Neotropical birds using a niche-based gap analysis

Knowledge of spatiotemporal distribution of biodiversity is still very incomplete in the tropics. This is one of the major problems preventing the assessment and effectiveness of conservation actions. Mega-diverse tropical regions are being exposed to fast and profound environmental changes, and the amount of resources available to describe the distribution of species is generally limited. Thus, the tropics is losing species at unprecedented rates, without a proper assessment of its biodiversity. Species distribution models (SDMs) can be used to fill such biogeographic gaps within a species’ range and, when allied with systematic conservation planning (e.g. analyses of representativeness, gap analysis), help transcend such data shortage and support practical conservation actions. Within the Neotropics, eastern Amazon and northern Cerrado present a high variety of environments and are some of the most interesting ecotonal areas within South America, but are also among the most threatened biogeographic provinces in the world. Here, we test the effectiveness of the current system of Protected Areas (PAs), in protecting 24 threatened and endemic bird species using SDMs. We found that taxa with wider distributions are potentially as protected as taxa with smaller ranges, and larger PAs were more efficient than smaller PAs, while protecting these bird species. Nonetheless, Cerrado PAs are mostly misallocated. We suggest six priority areas for conservation of Neotropical birds. Finally, we highlight the importance of indigenous lands in the conservation of Neotropical biodiversity, and recommend the development of community management plans to conserve the biological resources of the region.

Bulletin of the British Ornithologists’ Club

Bill Bourne died peacefully at Keith, in Scotland, on 31 May 2021, aged 91. Bill wrote so much: papers in this Bulletin are noted below, and are illustrative of the breadth and depth of his ornithological interests and knowledge. Much has been written about him over his working life as a medic, in travel, in research and writing. Bill featured as the 12th in the series 'Personalities' in the April 1978 issue of British Birds. The authors' perception of Bill, a legend of energy, knowledge and eccentricity were shown to stand the test of time. He joined the BOC in 1956. When I first met him in 1969 at the Autumn Scientific meeting of the British Ornithologists' Union he encouraged me to do so too, and he proved to be a great friend as I forged my early contacts in the world of exploration, museums, research and societies.Bill's energy and resourcefulness are well illustrated in his 1951 solo expedition to the Cape Verdes, as a result of which he contributed to the Bannermans' History of the birds of the Cape Verde Islands. His early enthusiasm for birds and their nests was imparted by three maiden aunts. At age seven his father introduced him to egg collecting, which he pursued for ten years, then saw the error, destroyed his collection, and joined the British Trust for Ornithology. He spent most of the war in Bermuda enjoying tropicbirds and terns, and learning about boats and seabirds. From this time his particular interest was the Tubinares. David Bannerman recounts how at the hottest time of year, with little money and no transport of any kind, Bill relied entirely on his wits in his solo Cape Verde endeavour. It says much for his stamina and enthusiasm that he walked across all of São Tiago, over the roughest country, while his journeys between the islands were perforce made in local schooners. With an interest more in ecology than in specimen collecting just one was taken, an example of a Purple Heron Ardea purpurea, from a colony he discovered on São Tiago. He was struck by the paleness of their plumage and the specimen he secured was sent to Paris. After some years, a new race was named by the Abbé René de Naurois in Bill's honour, A. p. bournei.Bill read medicine and zoology at Cambridge, and completed his training at St Bartholomew's Hospital, London. Service in the RAF took him to Malta, Jordan and the Middle East at the time of the Suez crisis, then Cyprus, where he was co-founder and first recorder of the Cyprus Ornithological Society. His passionate interest in islands and seabirds came to the fore when, in 1961, he proposed to found the Seabird Group, which eventually formed in 1965, a timely formation ahead of the Torrey Canyon disaster in March 1967. He became its first secretary, whilst in the role of adviser to the Royal Naval Bird Watching Society (RNBWS) he codified the collection of avian data from ships at sea (Sea Swallow 13: 9-16), including ocean weather ships in the eastern Atlantic at a time when reports were pouring in. During this period, when I first met Bill, he worked at Watford Gen...

“…Despite some problems of delimitation of these areas of endemism (see Silva et al [2004] and Lopes [2009]), three species appear to be closely associated to these enclaves: Pyrrhura pfrimeri (Pfrimer's Parakeet), Knipolegus franciscanus (Caatinga Black-Tyrant), and the recently described Campylopterus calcirupicola (Dry-forest Sabrewing) (Pinto, 1952;Mattos et al, 1991;Willis & Oniki, 1991;Silva & Oren, 1992;Olmos et al, 1997;Lima, 1999;Kirwan et al, 2001Kirwan et al, , 2004Pacheco & Olmos, 2006;Vasconcelos et al, 2006;Olmos, 2008;Lopes et al, 2010;Rego et al, 2011;Dornelas et al, 2012;Mazzoni et al, 2015;Lopes et al, 2017). Olmos (2005) also included Lepidocolaptes wagleri (Wagler's Woodcreeper) as an endemic of these dry forests.…”

Abstract. Cerrado dry forest enclaves have been treated as an endemic bird area. In the last years, some avifaunal surveys have been conducted in dry forests on the left bank of the São Francisco River, eastern Brazil. Nevertheless, there is a gap of detailed ornithological surveys in the Cerrado dry forest enclaves on the right bank of this river. Here, we present the first avifaunal survey of a Cerrado dry forest enclave on the right bank of the São Francisco River. The study area, named "Curral de Pedras", comprises a dry forest enclave and other associated habitats in central Minas Gerais state, southeastern Brazil. We recorded 172 bird species; nine taxa have their ranges strongly associated to the Caatinga; six present their ranges associated to the Atlantic Forest and one is typical of the Cerrado. Important records are those of Campylopterus calcirupicola, a recently described species associated with dry forests of central Brazil, and Celeus ochraceus, collected in its southernmost range. Furthermore, we obtained specimens that present intermediate phenotypes between the following woodcreeper species: Lepidocolaptes squamatus / L. wagleri and Xiphocolaptes albicollis / X. falcirostris. Those records reinforce the need of further sampling and collecting activities in those dry forest enclaves aiming future researches in taxonomy, geographic variation, and phylogeography.
