The use of (GACA)4 PCR to sex Old World vultures (Aves: Accipitridae)
Lappet-faced Vulture (Torgos tracheliotus) Science Article 1 abstract A PCR method was developed employing a single primer (GACA)4 to sex Black vultures (aegypius monachus), Lappet-faced vultures (Torgos tracheliotus), and Griffon vultures (Gyps fulvus). Using the (GACA)4 primer several PCR products were generated. M. WINK et al., Molecular Ecology, Vol. 7(6), p 779-782 Download article download […]

Variation in the quality of parental care at falcon nests in South Africa as evidence for postulated differences in food availabi lity.
Lanner Falcon (Falco biarmicus) Science Article 1 abstract Parental care by Peregrine Falcons Falco peregrinus an d Lanner Falcons F. biarmicus during the nestling period was studied in two areas of South Africa. Comparisons were made between the quality of care administered to broods of Peregrine Falcons at nests in tropical (the Soutpansberg) an d […]
Interactive behaviour between Bearded Vultures Gyp tus barbatus and Common Ravens Corvus corax in the nesting sites: predation risk and kleptoparasitism
Lammergeier (Gypaetus barbatus) Science Article 1 abstract Aims: Aggressive interactions between the Bearded Vulture Gyp tus barbatus and the Common Raven Corvus corax are frequent in the Pyrenean nesting sectors shared by both species. The Bearded Vulture’s nesting sectors are vulnerable to kleptoparasitism (food is stored in a visible and predictable manner in nests, perching […]
EASTERN WOOD-PEWEE ATTEMPTS TO FEED KILLDEER CHICKS
Killdeer (Charadrius vociferus) Science Article 2 abstract In July 1988, a wild Eastern Wood-Pewee (Contopus virens) was observed attempting to feed two captive Killdeer (Charadrius vociferus) chicks throughout one day.

Nest fate and vegetation characteristics for Snowy Plover and Killdeer in Colorado, USA
Killdeer (Charadrius vociferus) Science Article 4 abstract We quantified vegetation characteristics at nest sites of Snowy Plovers (Charadrius alexandrinus) and Killdeers (C. vociferus) in south-eastern Colorado during 1995 to assessinterspecific differences in nesting habitat and determine whether habitat characteristics influenced nest fate. Killdeers nested in areas with significantly more grass, litter, and vegetation within 10 […]
