Résumé :	A pair of Tengmalm's Owl Aegolius funereus bred in a conifer plantation in Jutland in 2007. The nest was placed in an old nest hole of Black Woodpecker Dryocopus martius, 10 m up in a big fir (planted in 1897). The first egg was estimated to have been laid about 22 April, and at least two young left the nest during the night of 25/26 May.This is the first confirmed breeding record of Tengmalm's Owl in Denmark outside of Bornholm. However, a pair probably bred in northern Jutland in 1968 (a juvenile bird seen 18 July), after an invasion of birds from the north and east. The breeding record here discussed may instead be the result of immigration from the south, from the small, but now increasing, population in North Germany. The establishment of a breeding population in Jutland should be possible because the conifer plantations now have an age where the trees are sufficiently big for breeding Black Woodpeckers, the nest holes of which are often used by other hole-nesting species, including Tengmalm's Owl.
