Sparrowhawk – a new breeding species in the Polish towns? - W. Biadun. - Berkut. 15 (1-2). 2006. - P. 120-124.
Research on synurbic breeding population of the Sparrowhawk was conducted in the urban zone of Lublin (SE Poland). It was part of a wide-scale study of the avifauna of the city that has been conducted for nearly 30 years now. The first four cases of breeding in the downtown area were noted in 2002. In 2005 and 2006 – six everyone. 9 breeding sites were localized altogether (Fig.). Five territories were found in parks, two – in cemeteries, and once per a little timbered area along a congested artery road, and a row of trees growing between two streets. All nests were situated in the vicinity of streets and/or lanes or near park or cemetery paths. Out of the 21 nests, 14 were located on coniferous trees (6 on larches, 5 on spruces, 3 on a pine). The nest height ranged from 8 to 25 m (14,5 m on average). In 2002 and 2004, pairs brought up only 1–4 fledlings (2,3/successful pair), later (2005–2006) number of fledlings increased to 2–6 (4,2/successful pair). It seems that the Sparrowhawk population in Lublin is an expansive one and that the number of breeding pairs will be growing in the future. [English].
