Journal of ornithology 2018 v.159 no.1 pp. 73-78
ISSN:
2193-7192
Subject:
Circus; birds of prey; breeding season; breeding sites; genetic variation; haplotypes; mitochondrial DNA; population growth; winter; Japan
Abstract:
... The Eastern Marsh Harrier (Circus spilonotus) is a raptor and inhabitant of East Asia, including Japan, and is classified as endangered (class IB) in Japan. The aim of this study was to reveal the genetic structure of a C. spilonotus population among several breeding sites, and to estimate whether the current population contains sufficient genetic diversity. We sequenced 1142 base pairs of the mit ...

Circus; DDT (pesticide); adults; biomass; birds of prey; blood sampling; breeding; conservation areas; diet; habitats; heterophils; immunity; leukocyte count; nesting sites; nestlings; nests; pollutants; polychlorinated biphenyls; risk; sympatry; urbanization; wetlands; wildlife; South Africa
Abstract:
... Persistent pollutants such as organochlorine compounds (OCs) have been highlighted as a cause of population decline in avian predators. Understanding patterns of OCs contamination can be crucial for the conservation of affected species, yet little is known on these threats to African raptors. Here we report on OC concentrations in an endangered predator endemic to southern Africa, the Black Harrie ...

Subject:
Circus; agricultural land; breeding; grasslands; habitats; nesting; nests; phenology; population dynamics; survival rate; Argentina
Abstract:
... We present novel data on breeding ecology and nest survival of the Cinereous (Circus cinereus) and Long-winged (C. buffoni) Harriers in modified grasslands of southern Argentina and we evaluate variations in daily nest survival rates (DSR) in relation to temporal and habitat variables. We studied three mixed nesting colonies embedded in agricultural landscapes along a road. We found that DSR decre ...

Abstract:
... Studying the Helminthological Collection of Museo de La Plata (MLP-He), several specimens of digeneans, recovered parasitizing a long-winged harrier, Circus buffoni (Accipitridae) from Buenos Aires Argentina, were analysed. The morphological and morphometric analysis of these specimens revealed the presence of two strigeid species, one of them new for science. Parastrigea buffoni n. sp. is charact ...
