The xerothermophilous grasshopper
Acrotylus insubricus
was found at a new, isolated site in Eastern Slovakia, at the northern boundary of its range. This is the first record in Slovakia after 60 ...years. In this paper this record is presented, with information on the habitat and accompanying species.
Ranunculus polyphyllus is a Eurosiberian species of the Eurasian forest-steppe zone, extremely rare in the western part of its distribution range, in Central Europe. In Slovakia, this lowland ...semiaquatic plant has its westernmost border, where only a few historic locations are known, and which have not been confirmed since 1965: one on the Podunajská nížina Lowland and three on the Východoslovenská nížina Lowland. These records, however, do not include any vegetation data. The species has been recently rediscovered in Slovakia on the Východoslovenská nížina Lowland: one historical site was confirmed in 2020 in the periodically inundated pasture near Strážne settlement, and a second site was found in 2021 near Zemplínske Hradište in a flooded depression in intensively used agricultural land which was formerly used as rice fields. In its European range, this species has been observed only in natural wetlands, and its ability to occupy secondary habitats has not yet been reported. Here we provide new data on the recent occurrence of Ranunculus polyphyllus in Slovakia with regard to its vegetation and habitat conditions.
Ural owls started nesting in smaller patches of woodland on the border between the Východoslovenská pahorkatina Upland and the Východoslovenská rovina Plain since 1994. The first data of the presence ...of Ural owls also in floodplain forest along the Latorica River in eastern Slovakia come from 1926, at first during the winter, and from 1998 also during the nesting period. In 2003 this species was heard in autumn courtship in this area, and on March 31, 2010 the first instance of nesting was noted in woodland to the south of the town Veľké Kapušany in the old nest of a common buzzard (Buteo buteo). This instance of nesting in wetland forest is the first nesting record of this species in this unusual nesting habitat in Slovakia.
Sova dlhochvostá hniezdila v menších lesných celkoch na rozhraní Východoslovenskej pahorkatiny a Východoslovenskej roviny od roku 1994. Od roku 1926 pochádzajú prvé údaje o výskyte sovy dlhochvostej aj z lužných lesov okolo rieky Latorica na východnom Slovensku sprvu v zimnom období, od roku 1998 aj z hniezdneho obdobia. V roku 2003 bol zistený na tomto území jesenný tok druhu a v roku 2010 bolo zistené prvé hniezdenie 31. marca v lese južne od mesta Veľké Kapušany v starom hniezde myšiaka (Buteo buteo). Tento prípad hniezdenia v lužnom lese je prvým záznamom o hniezdení tohto druhu v tomto netypickom biotope na území Slovenska.
Long-term monitoring of the Imperial Eagle in Eastern Slovakia has revealed that some pairs living permanently in an active agricultural environment (agrocoenosis) prove capable of adapting even to ...extreme conditions. In three cases eagles built their nests near railway lines (59, 22 and 15 m from the tracks), and in one case almost directly above a frequently-used road at a height of 21m.
Počas dlhoročného monitoringu orlov kráľovských na východnom Slovensku sa zistilo, že niektoré páry trvalo žijúce v kultúrnej poľnohospodárskej krajine (agrocenózy) sa dokážu prispôsobiť aj extrémnym podmienkam. V troch prípadoch si orly postavili hniezda pri železničnej trati (59, 22 a 15 m od koľajníc) a v jednom prípade tesne nad frekventovanou cestou vo výške 21 m.
In the years 2009-2012 a total of 316 individuals were marked in a colour ringing programme of the population ofA. pomarina in Slovakia. From this a total of 39 inds. were ringed with yellow readable ...plastic rings with a two-place alphanumeric code (all young in a nest) and 277 inds. (273 young and 4 adult inds.) with light-blue rings. For the entire period of the programme of marking the A. pomarina population in Slovakia in the years 2000-2012 a total of 952 inds. were ringed, 933 of which were young birds in nest and 19 adult individuals. In the period 2009-2012 48 records were obtained from observations of 35 individuals of different age categories (31 individuals from one to 11 years old, three of unknown age and one young individual about one month after fledging the nest). The age categories of immature individuals were determined, and six were found to be one-year-old individuals (12.5%) in the second calendar year of life after their first return from wintering grounds, six were two-year-old eagles (12.5%) and five were three-year-old eagles (10.4%) which spent breeding periods in Europe at a relatively small distance from their place of hatching. Adult individuals were found to be in their current breeding grounds at distances of 8-249 km from their hatching place. In the period 2000-2012 three individuals were recorded 3× and four individuals 2×. The results confirm breeding site fidelity in adults, but also the fidelity of immature individuals to their hatching place, and the return of one-year-old individuals from their wintering grounds to the vicinity of their hatching place immediately in the first year of life (that is, in the second calendar year).
V rokoch 2009-2012 sa na Slovensku oznacilo v programe farebného znacenia populácie A. pomarina 316 jedincov. Z toho žltými odcítatelnými plastovými krúžkami s dvojmiestnym alfanumerickým kódom spolu 39 jedincov (všetko mládatá na hniezde) a svetlomodrými krúžkami 277 jedincov (273 mládat a 4 adultné jedince). Za celé obdobie programu oznacovania populácie A. pomarina na Slovensku v rokoch 2000-2012 bolo oznacených 952 jedincov, z toho 933 mládat na hniezde a 19 dospelých jedincov. V období 2009-201 2 sa zistilo 48 záznamov o pozorovaní 35 jedincov rôznych vekových kategórií (31 jedincov jeden až jedenástrocných, tri jedince neznámeho veku a jeden mladý jedinec cca jeden mesiac po vyletení z hniezda). Determinované boli vekové kategórie immaturných jedincov, z ktorých bolo 6 jednorocných jedincov (12,5 %) v druhom kalendárnom roku života, po prvom návrate zo zimoviska, šest dvojrocných orlov (12,5 %) a pät trojrocných orlov (10,4 %), ktoré sa zdržiavali v hniezdnom období v Európe v relatívne malej vzdialenosti od miesta vyliahnutia. Adultné jedince boli zastihnuté vo vzdialenosti 8-249 km od miesta svojho vyliahnutia na svojich terajších hniezdiskách. V období rokov 2000-2012 tri jedince boli zaznamenané už 3×, štyri jedince 2×. Výsledky potvrdzujú vernost k hniezdisku u dospelých, ale aj vernost immaturných jedincov k miestam ich vyliahnutia a návrat jednorocných jedincov zo zimoviska do blízkosti miest ich vyliahnutia hned v prvom roku svojho života (teda v druhom kalendárnom roku).
In Slovakia during 2000-2008, 636 Lesser Spotted Eagles (Aquila pomarina) were marked with readable colour rings with double figure code. This is the highest number of Lesser Spotted Eagles marked in ...such a way in Europe. From this sample, 621 ind. (97.6 %) were chicks at the nest and 15 ind. (2.4 %) were adult birds which were trapped and consequently ringed. In this period, 2 colour series of rings have been used in Slovakia. In 2000 the ringing started with yellow rings, and up until the end of 2008, 631 ex. (616 young and 15 adults) were ringed. In 2008, the ringing started with light blue series of rings and 5 young at the nest were ringed. In addition to readable rings, aluminium ornithological rings of the Ringing Centres of Czech Republic (NM Praha) and Slovakia (NM Bratislava) have been used. The yellow series was used in fewer numbers also in Germany and Poland for marking the Lesser Spotted Eagle (Aquila pomarina), the Greater Spotted Eagle (Aquila clanga), and eventually their hybrids. In this article the authors reported first observations in Slovakia of such marked Lesser Spotted Eagles in the field. Observed eagles were 1, 2, 4, 5, 7 and 8 years old. Some of them were already breeding and were observed taking care of their chicks.
V rokoch 2000-2008 sa na Slovensku označilo farebnými odčítateľnými krúžkami s dvojmiestným kódom spolu 636 jedincov orlov krikľavých (Aquila pomarina), čo je najviac takto označených orlov krikľavých v Európe. Z tohto počtu bolo 621 ex. (97,6 %) mláďat na hniezde a 15 ex. (2,4 %) adultných vtákov, ktoré sa odchytili a následne okrúžkovali. V uvedenom období sa použili na Slovensku dve série farebných krúžkov. Žltými krúžkami sa začalo krúžkovať v roku 2000, do konca roku 2008 sa nimi označilo 631 jedincov (616 mláďat a 15 adultných jedincov). Svetlomodrou sériou krúžkov sa začalo krúžkovať v roku 2008 a označilo sa nimi 5 mláďat na hniezde. Súbežne s odčítateľnými krúžkami sa používali aj klasické ornitologické krúžky krúžkovacích staníc v Čechách (NM Praha) a na Slovensku (NM Bratislava). Žltá séria sa v menšej miere použila aj v Nemecku a Poľsku na označenie orla krikľavého (Aquila pomarina), orla hrubozobého (Aquila clanga), prípadne ich hybridov. V predloženom článku autori uvádzajú prvé pozorovania takto označených orlov krikľavých vo voľnej prírode na Slovensku. Pozorované orly boli vo veku 1, 2, 4, 5, 7 a 8 rokov od ich vyliahnutia. V niektorých prípadoch to už boli hniezdiace jedince zastihnuté pri odchovávaní svojich mláďat.
