Abstract

Thirty-three nest cavities of Green Woodpeckers (Picus viridis) in Hungary were documented over a period of 15 years (2006–2020). Thirteen different tree species were used. All documented cavities were in the main trunks of trees. The mean cavity height was 5.6 m and 1.5 m standard deviation and ranged from 2 to 9 m. Tree trunk diameters ranged between 36–55 cm with a mean of 43.1 cm and 4.2 cm standard deviation. A southerly orientation of cavity entrances prevailed with a mean direction of 187° clockwise from north. The results suggest that cavity-entrance orientation was non-random.
