Abstract.Seasonal differences of bird assemblages were
studied using mist-netting method during four
seasons (May, July, September, and December) in
two years (2014 and 2021) in a secondary wetland
habitat (7 mist-nets in willow grove, reed, and
scrubland) in Zvolen town, central Slovakia.
Altogether 54 species and 876 individuals of birds
were captured during 24 days of eight trapping
sessions (in 84 m of mist-nets at 7.3 ha study
plot). The highest number of mist-netted species
and individuals was found in July (36 species, 290
individuals), the lowest was in December (16
species, 153 individuals), pooled for both years.
The most abundant species were breeding species
Sylvia atricapilla, Parus major, Cyanistes
caeruleus and Turdus merula. The characteristic
reedbed birds included four Acrocephalus species,
Locustella luscinioides, Emberiza schoeniclus, and
scrubland species Luscinia megarhynchos, Sylvia
communis and Remiz pendulinus. Seasonal
differences in species number and abundance are
discussed. Regular wintering was found in
migratory species Prunella modularis and Erithacus
rubecula north of the known winter quarters of
their central European breeding populations. The
site fidelity and between-season retraps were
confirmed in 10 species and 54 individuals (18.5%
of all mist-netted species and 6.2% of all
individuals). Based on retrapped individuals, the
resident species P. major, C. caeruleus,
Aegithalos caudatus and T. merula were the most
faithful to the site, whereas inter-seasonal
retraps of migratory species were rare (e. g.
Sylvia atricapilla, Luscinia megarhynchos and
Phylloscopus collybita).
