Holes: secondary user - Tengmalm's Owl

This photo shows a Tengmalm's Owl (Boreal Owl) using an old Black Woodpecker nest-hole in a beech tree as a nesting site. Taken in the Sumava mountains, South Bohemia, Czech Republic, April 2005 (Dave Pullen). This site has been repeatably used for many years by the owls, possibly several generations of the family. The hole is so old that it has been weathered by the elements and the timber "healed". It thus appears almost natural i.e. note the rounded smooth entrance. In 2007 the hole was occupied by wasps and the owls moved on.
