The first breeding attempt of the Alpine Swift (Tachymarptis melba) in Slovakia is documented and range and population trend in Europe discussed. Four specimens of the species had appeared during the breeding season 2021 in Michalovce town, SE Slovakia, and a nest with the Alpine Swift eggs was documented on an unaccomplished panel building at a height of 22 m. The Alpine Swifts left the breeding site individually between September 27 and October 18. This breeding may be related to the increase of European population of Alpine Swift.

In 2019, 86 ringers ringed altogether 59 472 birds, of them 5641 were nestlings. That number was 1,58 % (90) higher compare to 2018. The ringed birds belonged to 151 species. The most numerous ringed species were Barn Swallow (Hirundo rustica, 7 324 ind.) Blackcap (Sylvia atricapilla, 7 212 ind.), Great Tit (Parus major, 5 322 ind.), European robin (Erithacus rubecula, 4 813 ind.), Blue Tit (Cyanistes caeruleus 3 973 ind.). The colour ringed schemes in Slovakia are given. Altogether 553 foreign recoveries were registered, out of them were 193 individuals ringed abroad and re-trapped in Slovakia and, 360 individuals ringed in Slovakia and re-trapped abroad.

The nest was situated in a grey poplar tree 15-20 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 of April, when the fledglings were probably already present in the nest, but no more data on their further success were obtained. In 2012 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.
