Does the great spotted woodpecker Dendrocopos major select holes for roosting?

Mazgajski T.

Polish Journal of Ecology

2002

Vol. 50, nr 1

99-103

Characteristics of Great Spotted Woodpecker roosting holes are compared with those used for breeding. Neither postbreeding nor winter roosting holes differed from woodpecker nests with respect to three species, condition, girth at breast height, cavity height or cavity direction. However, behavioural observations suggested that particular holes might be selected, probably in connection with microclimate condition and predator avoidance.

Nest-site characteristic of Great Spotted Woodpecker Dendrocopos major i central Poland

Mazgajski T.

Polish Journal of Ecology

1998

Vol. 46, no 1

33-41

The study was carried out in two nature reserves in Warsaw (central Poland) in 1992-1995. Following aspects of Dendrocopos major nest hole's localisation are describing: tree species, height above the ground, tree trunk girth, condition of tree, tree fragment (in which nest was located) and entrance's exposure. Near all nest's parameters were different between two study areas what suggest that Great Spotted Woodpecker is quite indiscriminate in nest site selection.
