2. Cerchneis tinnunculus, Linn. ( "Taarnfalk") nests in several steeples around Viborg.

At the churches of Mönsted and Daubjerg there were several family groups in 1880, each of 7 individuals, suggesting a particularly abundant source of food on the surrounding heather (lizards). In the area of Thisted, where the tower falcon broods very often, young were always present in broods of 6, only once did I find a group of 7 on Egebäksande (H.)

In Horsens I found kestrels brooding on the churches of Vähr, Hansted, Hundslund, Thyrsted and Oelsted. In the steeple of Vähr I found a nest with 6 eggs on 6 May 1875, 6 eggs on 30 April 1876, 4 eggs on 28 April 1878; in 1877 and 1879 there were none, on 2 May 1880 they had 5 eggs, in 1882 also 5 eggs, and in 1883 seven.

In Oelsted 5 eggs on 3 May 1879, in 1882 also 5, and in 1883 6 eggs.

On the churches (Our Lady’s and St. Peter’s) of Copenhagen, I have often seen it in the autumn and winter of 1879; in spring 1880, it brooded on Our Lady’s church, the "round tower" and the law firm building (in a valve) and certainly also on St. Peter’s Church. (F.)
