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.
The 1980’s and 90’s saw growth in the population and expansion of the areas occupied by White-tailed Sea Eagles over the whole territory of their occurrence in Europe. Under this influence the number of these eagles observed during the nesting period also increased in Eastern Slovakia. The most frequent occurrences have been recorded in the wetland woods along the River Latorica on the East Slovakian Plain, but so far without any documented nesting. In 2002 one pair built a nest in the Vihorlat Hills near Zemplínska šírava reservoir, but they did not actually nest in it either that or the following year. Breeding by these eagles in these hills was noted over 70 years ago by Hrabar (1932) and Molnár (1933), but no nesting was documented. Nesting was documented for the first time in 2004, when one pair successfully raised two offspring. This pair successfully bred in the same nest in 2005 and 2006 too.
Nesting of the Lesser Spotted Eagle (Aquila pomarina) at its hatching site
Colour rings with alphanumeric codes have been used on the Lesser Spotted Eagles since 2000. On April 24, 2007 an eagle with a yellow ring I9 was photographed in the "Ondavská vrchovina" highlands near the village of Lieskovec in Humenné district. It was found out that the eagle was ringed on the same site on July 4, 2002 as a chick on the nest. After further observations the adult male was spotted feeding its chick in the nest, which was located only 130 m from the one it hatched at. If it could be proved that the female at the nesting site, which has been regularly surveyed since 1985 has not changed, nesting of a son and a mother could not to be ruled out in this case.
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.
