The long-legged buzzard (Buteo rufinus) in Slovakia in the past and present

Published Online: 22 Feb 2013
Page range: 1 - 16

Abstract

Abstract

In the 1 9th century the long-legged buzzard bred in the Balkan Peninsula only in Greece. From the first half of the 20th century it began to expand to the north, and at the end of 201 2 the northern boundary of its breeding expansion in south-eastern Europe extended to central Hungary, south-western Romania, Romanian Dobruja, the southern half of Ukraine and along the western border of Kazakhstan. In the work are 232 faunistic data on the occurrence of the species on the territory of Slovakia from the year 1 870 to the end of 201 2. In the period from 1 911-1 950 only 7 cases were found here; from the period 1 951-2000 43 observations exist, and for the short period from 2001-201 2 there are as many as 1 80, of which 98 occurred in the year 201 2 alone. The text in particular evaluates the invasive occurrence of the species in 201 2 in Slovakia and its neighbouring countries (Austria, Czech Republic and Poland). Given this increasing trend in the frequency of occurrence of the long-legged buzzard in Slovakia, its breeding on the territory of Slovakia in the near future can be anticipated, though by the end of 201 2 this had not yet to be confirmed.

Diet composition of the scops owl (Otus scops) in central Romania

Published Online: 22 Feb 2013
Page range: 17 - 26

Abstract

Abstract

Insect diversity correlates negatively with increasing management intensity of grasslands and with latitude. We supposed that similar patterns might be found in the diet spectra of insectivorous birds. The diet composition of the insectivorous scops owl was studied by analysing the prey remnants collected from 21 nests during 2008-2009 in an extensively cultivated rural area in the centre of the owl’s distribution range in Central Romania. Altogether 831 prey items belonging to 45 prey taxa were identified. Similarly to the other parts of the scops owl range, orthopterans were high dominant prey items (86.8%) - especially bush-crickets Tettigoniidae (78.6%). In food samles were found also beetles (Coleoptera, 5.7%) and rarely spiders Araneidea, moths Lepidoptera, mantids Mantodea, Hymenoptera and Neuroptera (<1 .5%). Vertebrates were rarely represented by rodents (2.5%) and passerines (1 .3%). The following diagnostic prey species were identified in 20 nests using the MDFM method: bush-crickets Tettigonia viridissima, Decticus verrucivorus, Metrioptera bicolor and other species of the family Tettigoniidae, the beetle Onthophagus spp., the cricket Gryllus campestris and other unidentified beetles Coleoptera g. sp. Furthermore, the scops owl’s diet in different parts of its range was compared.

As expected, there were more Orthoptera and generally more prey taxa in food in the range centre than at its northern limit.

First observation of the black-winged kite Elanus caeruleus in Slovakia

Published Online: 22 Feb 2013
Page range: 27 - 30

Abstract

Abstract

The details and circumstances of the first observation of the black-winged kite Elanus caeruleus in Slovakia are described in the article. An adult individual of the nominate subspecies of the black-winged kite, in the age of at least two years, was observed on August 1 5, 201 2 in the Žitavský luh Nature Reserve, SW Slovakia. Behavioural and ecological information pertaining to the observation are provided, including weather conditions prevailing in the region immediately before the observation day.

The first observation of the Levant sparrowhawk Accipiter brevipes (Severtzov, 1850) in Slovakia

Published Online: 22 Feb 2013
Page range: 31 - 36

Abstract

Abstract

On May 1 5, 201 2 an individual of Levant sparrowhawk Accipiter brevipes was observed at the southern edge of Trebišov town in eastern Slovakia, situated in the Východoslovenská rovina Lowlands. The sighting was documented with photographs. This is the first recorded occurrence of this species in terms of the bird fauna of Slovakia. The present article describes in detail its distribution and breeding in eastern Hungary and western Romania, based on an isolated population in the Pannonian Basin at the north-western edge of its breeding range. The occurrence of the Levant sparrowhawk beyond the boundaries of its breeding range and outside the Pannonian Basin consists mostly of rare movements by young individuals (northern Moravia, central and northern Poland) far north of its breeding range. An adult male was observed in south-eastern Poland in the pre-breeding period, and in Slovakia an adult female was observed in the breeding period.

Nesting by the Eurasian eagle owl (Bubo bubo) in a nest of the whitetailed eagle (Haliaeetus albicilla)

Published Online: 22 Feb 2013
Page range: 37 - 40

Abstract

Abstract

In 2011 and 201 2 two breedings by a pair of Eurasian eagle owls were observed in an old white-tailed eagles’ nest at Blatná Polianka in the Senianske rybníky SPA. The nest was situated in a grey poplar tree 1 5-20 m above the ground in a treebuffer by the rivulet Okna, in open lowland landscape without woodland, just with linear tree vegetation and scattered trees. In 2011 incubation of the clutch was observed and the female was present in the nest even at the end ofApril, when the fledglings were probably already present in the nest, but no more data on their further success were obtained. In 201 2 the pair of Eurasian eagle owls bred in the same nest again, but in May the nest was already abandoned and we suppose predation of the clutch, probably by ravens. This occasion is the third known breeding attempt by the Eurasian eagle owl in a raptor nest built in a tree, and the first known occasion of breeding in a white-tailed eagles’ nest in Slovakia. The obtained data also document the further spreading of the species in the Dolný Zemplín region into unusual habitats of a lowland agricultural landscape with very few trees.

Summary of raptor and owl ringing in Slovakia in 2011

Published Online: 22 Feb 2013
Page range: 41 - 44

Abstract

Abstract

The article provides basic information about the number, species and recoveries of ringed birds of prey and owl species in Slovakia in 2011 . The report follows similar papers from the following periods: 2002-2004, 2005-2006, 2007-2008, 2009 and 201 0. In 2011 a total of 61 0 individuals were ringed in Slovakia, of which 509 individuals were birds of prey (1 6 species) and 1 01 individuals were owls (9 species). From the total number, 426 raptor nestlings and 46 owl nestlings were ringed. In comparison with the previous year 201 0 the number of ringed birds of prey and owls increased by 11%.

Page range: 45 - 77

Abstract

Abstract

The aim of the bibliography is to provide a list of publications on the raptors and owls of Slovakia and of Slovak authors including articles dealing with various organisational issues. The previous parts, which focused on genera from the orders Accipitrifromes, Falconiformes and Strigiformes, are now followed by a fifth part focusing on the raptor and owl species mentioned in various wider associations in the individualarticles. The species, objective and author indexes and the list of periodicals enable better overview
