for insects over the -swamps and along the river was very fine, and 

 we never tired of watching them. 



There is an island near the German frontier which can boast of 

 a small colony of Caspian Terns, Hydroprogne caspia (Pall.) — 

 about a dozen pairs — strictly preserved by an ornithological society. 

 On the Government Preserves there are colonies of Black-headed 

 (iuUs, Lams ridibiindus, L., Common Gull, Lams canus, L., and 

 Herring Gull, Lams ari^entatus, Briinn., and also a small colony of 

 the Little Gull, Lams mimitus, Pall., which here finds its western 

 limit and is treated to well-merited protection like the Caspian 

 Tern. Strange to say, we never saw the Bittern, Botanrus stellaris, 

 (L.), although it breeds fairly regularly in many places. 



Of the Grebes, there is a large colony of the Great-crested Grebe, 

 Podiceps cristatus (L.), on the Government Preserves, and the 

 Red-necked Grebe, Podiceps griseigena, (Bodd.), and Eared Grebe, 

 Podiceps nigricollis, Brehm., also breed sparingly. 



A very interesting and conspicuous bird in Jutland is the White 

 Stork, Ciconia alba, Bechst., which is strictly preserved. Their huge 

 nests are placed on the thatched roofs of the farm buildings — always 

 at an end, and in many places old cart-wheels or hurdles are put up 

 by the owners to form a nesting platform for them. These birds 

 are never molested by the peasants, and we were not fortunate 

 enough to see inside a nest, although we tried various ruses for the 

 purpose, the expression of a desire to photograph, etc. We saw an 

 old bird flying to a nest with a huge rat in its bill. The species 

 makes a curious snapping noise by striking together the upper and 

 lower mandibles, for they have no vocal organ. 



Of the Hooded Crow, Corone comix (L.), the native crow of 

 Denmark, we saw .but a single example. It is abundant in the 

 forests towards the cast. 



In many places Coots, Fulica atra, L., were numerous, but we 

 seldom saw the Moor-hen, Gallinula chlorupiis (L.). The latter fact 

 we often remarked, and it is the more strange as the country seems 

 perfectl}' adapted to their habits. 



Of Jutland's small birds one of the most abundant species is the 

 beautiful Blue-headed Yellow Wagtail, Bndytes flava (L.). They 

 were everywhere common, and we found man}' nests. The latter 

 were placed in various situations, a favourite site being at the side 

 of the numerous water-channels and gutters ; and they appeared' 

 to prefer those that were not too dry. We occasionally, however.
