[Concluded from p. 372.] 

 MlCROPUS APUS (L.). 



Common. Arrives in East Prussia later than in Western 

 Germany. In the vast forests of the south-eastern parts 

 they are often found breeding in hollow trees. 



Caprimulgus europ.eus, L. 



Common, breeding all over the province. 



GeCINUS VIRIDIS (L.). 



Commonly breeding ; eggs taken in May. Eastern speci- 

 mens seem to have larger bills as a rule, but I have not 

 sufficient material at hand to make out whether this is con- 

 stant or not. 



Gecinus canus (Gm.). 



This Woodpecker, which is so common in Hesse and other 

 parts of Germany, is extremely rare in Prussia. I have only 

 seen one, killed near Blandau in December 1877. 



Dendrocopus major (L.). 



Very numerous everywhere. As a rule the bills of East- 

 Prussian specimens are rather strong. 



Dendrocopus medius (L.). 



By no means rare in the woods, but not found every- 

 where. 



Dendrocopus minor (L.). 



Is found in many localities, except in the vast pine-forests, 

 but is rare. 



Dendrocopus leuconotus (Bechst.). 



Very rare, and only observed in the vast pine-forests of 

 the south-east. As it is no doubt a stationary bird, it must 

 necessarily breed in East Prussia. 



PiCUS MARTIUS, L. 



The Great Black Woodpecker is still rather numerous in 

 the great forests of East Prussia. It makes its large nest-
