How has the breeding bird assemblage of the Dařanec NR changed after 24 years?

Abstract

The author conducted a census of breeding birds in the Dařanec NR (Hlučínská Hilly
Land, Opava District) once a week during the April‒June 2020 period, using a belt method
(width 50 m, area 5.6 ha). The results were compared with data collected in 1996 by the same
method. Out of 20 species recorded in both years, 14 species showed lower quantity than in
1996. Overall density of the breeding bird assemblage (191.8 pairs / 10 ha) was lower by 30%
in 2020. From the faunistic similarity and dominancy perspective, the breeding bird assemblages
in 1996 and 2020 were similar to very similar, and identical, respectively.
