Here we present the first description of nests for the Varied Solitaire Myadestes coloratus, a regional endemic species (Panama and Colombia). We found two nests in Cerro Chucantí Natural Private Reserve (CCNPR), the first nest was seen on May 6, 2019 with three hatchlings inside and the second on May 9, 2020 with three eggs. The nests were constructed out of green mosses and foliaceus liverworts over tree trunks covered with moss, they were cup shaped, at 1.3 and 1.5 meters high. The GPS coordinates of the nests were (8° 47’44.8” N, 78°27’47.4 W, 1276 m) and (8° 48’09.5” N, 78°27’37.0 W, 1393 m) respectively. This report represents the first for this species which is under the Endangered (EN) category of Panama´s List of threatened species of Fauna and Flora by Ministerio de Ambiente.

The Impact

Key Biodiversity Areas (KBAs) are sites that contribute significantly to the protection of the planet’s biodiversity. In this study, we evaluated the annual burned areas and the intensity of the fires that affected Bolivia and its 58 KBAs (23.3 million ha) over the last 20 years (2001–2020). In particular, we analyzed the impact of wildfires on the distribution of Bolivian birds at the levels of overall species richness, endemic species and threatened species (Critically Endangered, Endangered, Vulnerable). We found that at the KBA level, the cumulative area of wildfires was 21.6 million ha, while the absolute area impacted was 5.6 million ha. The KBAs most affected by the wildfires are located in the departments of Beni and Santa Cruz; mainly in the KBAs Área Natural de Manejo Integrado San Matías, Oeste del río Mamoré, Este del río Mamoré, Noel Kempff Mercado and Área Natural de Manejo Integrado Otuquis. The wildfires impacted the distribution of 54 threatened species and 15 endemic species in the KBAs. Based on the results of this study, it is a priority to communicate to Bolivian government authorities the importance of KBAs as a strategy for the conservation of the country’s biodiversity and the threats resulting from anthropogenic fires.

Accurate maps of species ranges are essential to inform conservation, but time-consuming to produce and update. Given the pace of change of knowledge about species distributions and shifts in ranges under climate change and land use, a need exists for timely mapping approaches that enable batch processing employing widely available data. We develop a systematic approach of batch-processing range maps and derived Area of Habitat maps for terrestrial bird species with published ranges below 125,000 km2 in Central and South America. (Area of Habitat is the habitat available to a species within its range.) We combine existing range maps with the rapidly expanding crowd-sourced eBird data of presences and absences from frequently surveyed locations, plus readily accessible, high resolution satellite data on forest cover and elevation to map the Area of Habitat available to each species. Users can interrogate the maps produced to see details of the observations that contributed to the ranges. Previous estimates of Areas of Habitat were constrained within the published ranges and thus were, by definition, smaller—typically about 30%. This reflects how little habitat within suitable elevation ranges exists within the published ranges. Our results show that on average, Areas of Habitat are 12% larger than published ranges, reflecting the often-considerable extent that eBird records expand the known distributions of species. Interestingly, there are substantial differences between threatened and non-threatened species. Some 40% of Critically Endangered, 43% of Endangered, and 55% of Vulnerable species have Areas of Habitat larger than their published ranges, compared with 31% for Near Threatened and Least Concern species. The important finding for conservation is that threatened species are generally more widespread than previously estimated.

Previously known from two specimens, Kaempfer's Tody-tyrant Hemitriccus kaempferi is a globally threatened species endemic to the southern Brazil Atlantic Forest. The first field observations of this little-known taxon were made in the 1990s and our data therefore provide the first published information on its natural history, including breeding biology, behaviour and vocalizations, as well as a new locality. As very little information has appeared in the literature concerning the identification of this species, we present notes on its plumage and habits. Remarks concerning the species's conservation prospects and the importance of the remaining forest in the vicinity of the type-locality for other threatened bird species are made.

The island of Santa Catarina lies in the Atlantic Forest Domain of southern Brazil, one of the most threatened ecosys tems on the planet. It holds a wide variety of habitats, ranging from sand dune ‘restingas’ to mature rain forest. We report, for the first time, a survey of the bird species and their conservation status for the different habitats present on the island. We recorded 269 bird species of 54 families (25 species were seabirds). More than 50% (140) of the total number of species were residents or probable residents, 20% (58) were visitors and a relatively high number of species (61, 23%) had indeterminate residential status. Nearly 15% (35 species) of the 244 landbird species observed were endemic to the Atlantic Forest. Habitat specificity was recorded for 40% (97 species). We recorded one Endangered (Solitary Tinamou Tinamus solitarius), one Vulnerable (White-necked Hawk Leucopternis lacernulata), and three Near-threatened species (Azure Jay Cyanocorax caeruleus, Azure-shouldered Tanager Thraupis cyanoptera, Black-backed Tanager Tangara peruviana). We also recorded six locally threatened species that we predict will become extinct in the near future. The future for the birds of the island is uncertain, especially for habitat specialists, due to habitat loss for resort developments, and a lack of concern by the government and local people.

SummaryAn annotated compendium of all those bird species known to have occurred in the lowland “Man and Biosphere” Beni Biological Station (B.B.S.) reserve is provided. Previous checklists are reviewed, together with sightings accumulated over the 1992–1995 period during which approximately 70 new species have been added to the reserve inventory, bringing the total to 478. Occurrence across the 12 delineated habitats, relative abundance and sighting documentation are given for each species. The avifauna of the B.B.S. is mixed biogeographically; in addition to a substantial component of lowland birds widespread throughout South America, it is composed of Amazonian, cerrado and chaco elements also. Representation from the Bolivian Yungas is minimal. Significantly, no less than four threatened and 15 near-threatened species have occurred, including the little known Bolivian endemic Unicoloured Thrush Turdus haplochrous, and the enigmatic White-winged Nightjar Caprimulgus candicans, known until recently only from Emas National Park (Brazil). Short accounts are provided detailing records of all of these species. Birds of the reserve core, consisting largely of humid tropical forest formations inundated during the austral summer, appear not to be subjected currently to any serious environmental degradation, although some subsistence clearance by Chimane Indians in the northern reaches of the reserve gives some cause for concern. Of much greater import, however, are changes occurring outside the confines of the B.B.S. These include increasing urbanization immediately to the west (and associated road upgrading) and forest fragmentation to the south brought about by logging. The latter is especially worrying because linkage of the B.B.S. forest block to surrounding forest is already physically tenuous, and therefore it is imperative that future logging activities be geared to minimize isolation occurring and the damaging restriction of gene flow. Monitoring in rainforest immediately south of the reserve should become routine to warn of putative avifaunal impoverishments. Extensive surveying of the 2,500-ha El Porvenir éstancia (savanna and related forest islands) due to be assimilated shortly into the B.B.S., which constitutes less than 2% of the area under consideration, has shown that it is used by no less than three threatened and up to nine near-threatened species. In the absence of data relating to other savanna areas (c. 15%) at present, the exact status of each species at the B.B.S. remains imprecise and begs for further research to be undertaken. Unfortunately, present management of the El Porvenir savanna is not conducive to the long-term maximization of populations of these species, several of which have local strongholds in this part of Beni. We recommend that the current policy of cattle ranching adopted by this éstancia should cease or be reduced dramatically, to minimize grazing and trampling damage, and that measures should be taken to reduce incursions of fires started wilfully in neighbouring properties. The Academia Nacional de Ciencias de Bolivia, which administers the reserve, should be encouraged to safeguard and enhance the savanna complement further by ensuring that the impending ratification of El Porvenir proceeds as quickly as possible, and by purchasing additional tracts of land to the south of the present southern reserve boundary, where feasible. Such actions should not only secure the future of the biota of the savanna habitat within the B.B.S. but also should ameliorate the degree of isolation which has occurred already by preserving the “curiches” (former river beds) and forest islands which act as access corridors for forest-dwelling and other birds.

The present study was conducted in Sultanpur National Park Gurgaon, Haryana (India) from February, 2011 to January, 2012 to analyze the avian diversity along with its status and abundance. During the study period, a total of 113 species of birds belonging to 14 orders, 35 families and 80 genera were identified. Maximum 41 species belonging to 12 families of order Passeriformes represented 36.28% of the total identified avian fauna while Podicipediformes and Strigiformes were the least represented avian orders (0.88%) with one species each,namely, Little Grebe, Tachybaptus ruficollis and Spotted Owlet, Athene brama respectively. Out of total reported 113 species, 64 were ‘resident’ species and 49 were ‘migrant’ species. Most of the migratory species were winter visitors except Red throated flycatcher, Ficedula parva; Orange Headed Thrush, Zoothera citrine and Eurasian Golden Oriole, Oriolus oriolus which were summer visitors. In all, 42 species were ‘common’, 33 species were ‘uncommon’ and 38 species were ‘occasional’ bird species. Based on sighting, White Breasted Kingfisher, Halcyonsmyrnensis; White Breasted Water Hen, Amaurornis phoenicurus; Common Moorhen, Gallinule chloropus; Black Wing Stilt, Himantopus himantopus; Red Wattled lapwing, Vanellus indicus; Cattle Egret, Bubulcus ibis and Indian Pond Heron, Ardeola grayii were common wetland bird species of Sultanpur National Park while Pied king fisher, Ceryle rudis and Coppersmith Barbet, Megalaima haemacephala were ‘rarely sighted’ bird species. During the study period, 7 ‘globally threatened’ species, namely, Painted Stork, Mycteria leucocephala; Black neck Stork, Ephippiorhynchus asiaticus; Black headed Ibis, Threskiornis melanocephalus; Darter, Anhinga melanogaster; Pacific Reef Egret, Egretta sacra; Sarus Crane, Grus antigone alongwith Hogson bushchat, Saxicola insignis were also recorded from the study area.

In the Cerrado, veredas are linear physiognomies that occur on hydromorphic soil usually along narrow water courses. They often growth on flat terrain or near headwaters. They are characterised by the abundance of buriti palms (Mauritia flexuosa) that growth over other trees, numerous shrubs and a dense herbaceous stratum. Despite being common landscape elements through the Cerrado's extension, the use of veredas by birds has not been examined in detail. This study aimed to review studies of birds and veredas in the Cerrado. Publications (n = 25) reported the use of veredas by 261 bird species. Only 13 of them had aspects of their biology (reproduction and feeding) studied in detail. Veredas are poorly used by Cerrado's endemic species, but are the major habitat requirement of several species. The richness of bird species found in veredas is increased by their inclusion in the home range of forest, savanna and grassland species. This study also discusses the values of veredas to the regional biodiversity, and the major threats to their conservation inside and outside the system of nature reserves. Suggestions for future research on birds and veredas in Cerrado also are provided.

Mammalian Predators

Extinctions and threats of extinctions in avifaunas on oceanic islands appear to be influenced by several island characteristics and introduced mammalian predators. These predators may have caused a “filter effect”; low numbers of threatened avian species on some islands might be due to high rates of past extinctions. Using path analysis, we examined these factors and the influence of human population size (as an indicator of human activity) on the number of species extinctions and threatened bird species on islands. Human population size had substantial influences on the number of extinctions (standardized partial regression coefficient ρ = 0.315, N = 172, P = 0.0005) but not on the number of threatened species on oceanic islands (ρ = -0.061, P = 0.43), independent of the number of introductions of predator species. The number of extinctions on islands produced a significant filter effect (viz., had a negative impact; ρ = -0.186, P = 0.003) on the number of currently threatened species. The activities of human populations, including mammalian predators they introduced, have likely resulted in a greater number of bird extinctions on these islands, and producing a significant filter effect, wherein islands with larger human populations now have fewer threatened species.

The Western Ghats

Pollination ecology and the breeding system of four endemic species of Syzygium (S. heyneanum, S. travancoricum, S. laetum and S. mundagam) of the Western Ghats, India are investigated. The floral traits are used for ordination analysis to understand if the species form any cryptic groups and whether this grouping predicts the pollination syndrome and the breeding system. Pollinators were distinguished from frequent visitors by studying their efficiency to transfer pollen to the stigma or induce fruit set following their exclusive visit to virgin flowers. The species formed two groups in the ordination map: the S. heyneanum and S. travancoricum group and the S. laetum and S. mundagam group. The flowers of studied species attracted 3–23 species of animals during the day, but none were encountered during the night. Flowers of S. heyneanum and S. travancoricum were visited by a large number of insect species of which only a limited number turned out to be the pollinators. S. laetum and S. mundagam attracted two bird species apart from a few insect species. In S. laetum, although birds did not bring about pollination directly, their visits facilitated anemophily by releasing pollen to the air by causing physical disturbance to the flowers. In S. mundagam, both birds and wind were involved in pollination. S. heyeanum and S. travancoricum were fully self-compatible, whereas S. laetum and S. mundagam were partially self-compatible.
