lavender, thyme, &c. ; and white-coloured plants are much 

 liked. 



MUSCICAPA PARVA, Bcchst. 



Is not to be found in most localities in East Prussia, 

 being an inhabitant of forests of beech and hornbeam 

 {Fagus sylvatica and Carpinus betulus). Herr Robitzsch, 

 however, found it breeding near Norkitteu, in the district of 

 Insterburg. 



MUSCICAPA GRISOLA, L. 



Common from the beginning of May to September. Eggs 

 are found at the end of May and in June. 



MUSCICAPA ATRICAPILLA, L. 



Plentiful on migration at the end of April and in Septem- 

 ber, but comparatively rare during the breeding-season. 



Ampelis garrulus, L. 



The Waxwing comes every year to East Prussia ; at least 

 I was able to verify its occurrence in every winter from 1879 

 to 1886, and in 1889 and 1890. In some winters consider- 

 able numbers are seen, while they are very scarce in others. 

 There are certain places where the bird may always be found 

 as long as there are any in the country. They are especially 

 fond of the berries of Viscum album, and in searching for 

 Waxwings one should be on the look-out for mistletoe. 

 They are also fond of the berries of Vaccinium oxycoccos, and 

 I have seen them eating these berries on the moor, the only 

 occasion on which I have seen them descend to the ground. 



Chelidon urbica (L.). 



HiRUNDO RUSTICA, L. 



Clivicola riparia (L.). 



All three species of Swallow are common. A hill near 

 Pillau has its name (Schwalbenberg) from the immense 

 numbers of Clivicola I'iparia vi\\\c\x frequent it. Before the 

 Swallows leave the country, incredible numbers associate to 

 sleep in the reeds of the Frische Haff, and it is quite exciting 

 to see them, and to hear them rising on wing with a sound 

 like thunder.
