The Structure of Vertebrate Predator Community in North-Eastern Belarus Before and After Naturalization of the American Mink and Raccoon Dog
Folia Zool. – 57(4): 373–391 (2008) The structure of vertebrate predator community in north-eastern Belarus before and after naturalization of the American mink and raccoon dog Vadim E. SIDOROVICH*, Anna A. SIDOROVICH, Vladimir V. IVANOVSKIJ, Mihail M. PIKULIK and Elena P. SHINKEVICH The Vertebrate Predation Research Group, Institute of Zoology, National Academy of Sciences of Belarus, Akademicheskaya str. 27, Minsk – 220072, Belarus; e-mail: [email protected] Received 10 August 2007; Accepted 23 June 2008 Abstract. The structure of the vertebrate predator community in north-eastern Belarus has been examined before and after naturalization of the American mink and raccoon dog. Species composition of the community, population density and biomass, portion of each species in the pooled community density and biomass, species body mass and size structure of the community were investigated. The community consisted of 36 native predator species, and 11 other predator species were sporadically registered in the area in both periods before the American mink and raccoon dog expansion and after the introduced species have reached a high population density. Separating predator species into four size groups, we found that in terms of total density the largest portion of the community belonged to small predators, while large predators formed the smallest portion. In terms of total biomass, the larger medium-sized predator group predominated over other size groups. Despite decline in the populations of ten native predator species, the total community density and biomass as well as portions of different size groups appeared to be very similar before and after naturalization of the introduced predator species. -

Eared Owls in New Jersey
j RaptorRes. 23(4):162-166 ¸ 1989 The Raptor ResearchFoundation, Inc. OBSERVATIONS ON THE EVENING DEPARTURE AND ACTIVITY OF WINTERING SHORT-EARED OWLS IN NEW JERSEY THOMAS BOSAKOWSKI ABSTR^CT.--WinteringShort-eared Owls (Asioflammeus) were primarily crepuscularand nocturnal. Roostdeparture occurred most frequently after sunset(83%) with mostexceptions occurring on heavily overcastdays. Owls usually departed singly or in tandemand engaged in a steadydirect flight, presumably to a predeterminedhunting area. Hunting was rarely initiatednear the roostsite. Night observations up to 5 hr after sunsetrevealed that owls huntedcontinuously into the night and were not merely crepuscular.Despite their reputationas an on-the-wingpredator, extended periods of perch-huntingwere oftenobserved after sunset,particularly on windlessnights. Active hunting from percheswas evidenced by a continualseries of pouncesand huntingflights that werelaunched from the sameor nearbyperches.

Gender Determination in the Western Marsh Harrier (Circus Aeruginosus ) Using Morphometrics and Discriminant Analysis
J. Raptor Res. 40(1):000–000 E 2006 The Raptor Research Foundation, Inc. GENDER DETERMINATION IN THE WESTERN MARSH HARRIER (CIRCUS AERUGINOSUS ) USING MORPHOMETRICS AND DISCRIMINANT ANALYSIS CHRISTIAN BAVOUX Le Marais aux Oiseaux, Les Grissotie`res, 17550 Dolus-d’Ole´ron, France GUY BURNELEAU 2, rue du Port de Chiffeu, Mauzac, 17320 Saint-Just-Luzac, France VINCENT BRETAGNOLLE1 Centre d’Etudes Biologiques de Chize´, Centre National de la Recherche Scientifique, 79360 Beauvoir-sur-Niort, France ABSTRACT.—When adult, the gender of Western Marsh Harriers (Circus aeruginosus) are determined on the basis of the presence of gray feathers on the wing and on the tail in the males. However, males of this species in southwestern France have female-like plumages, lacking gray feathers, and thus, gender determination is impossible by using coloration alone. We investigated sex determination using biometric parameters in a study site located in southwestern France. From one to six measurements (body mass, bill length, wing chord length, tarsus length and width, and tail length) were taken from 243 marsh harriers of known gender (156 males and 87 females), marked in the study site, and subsequently re-sighted. Additionally, 30 marsh harriers specimens were measured by two observers to establish within and between observer repeatability values, as well as within bird repeatability for the six biometric parameters. Using quadratic Discriminant Analysis, we showed that it was possible to sex individuals of this species with .99% accuracy on the basis of only two parameters: bill length and body mass. Actually, using bill length alone provides very good indication of gender (accuracy . -
Apparent Hybridisation of Firecrest and Goldcrest F
Apparent hybridisation of Firecrest and Goldcrest F. K. Cobb From 20th to 29th June 1974, a male Firecrest Regulus ignicapillus was seen regularly, singing strongly but evidently without a mate, in a wood in east Suffolk. The area had not been visited for some time before 20th June, so that it is not known how long he had been present. The wood covers some 10 ha and is mainly deciduous, com prised of oaks Quercus robur, sycamores Acer pseudoplatanus, and silver birches Betula pendula; there is also, however, a scatter of European larches Larix decidua and Scots pines Pinus sylvestris, with an occasional Norway spruce Picea abies. Apart from the silver birches, most are mature trees. The Firecrest sang usually from any one of about a dozen Scots pines scattered over half to three-quarters of a hectare. There was also a single Norway spruce some 18-20 metres high in this area, which was sometimes used as a song post, but the bird showed no preference for it over the Scots pines. He fed mainly in the surround ing deciduous trees, but was never heard to sing from them. The possibility of an incubating female was considered, but, as the male showed no preference for any particular tree, this was thought unlikely. Then, on 30th June, G. J. Jobson saw the Firecrest with another Regulus in the Norway spruce and, later that day, D. J. Pearson and J. G. Rolfe watched this second bird carrying a feather in the same tree. No one obtained good views of it, but, not unnaturally, all assumed that it was a female Firecrest. -
