31. Winge on the Birds of the Danish Lighthouses, 1898.

Fugle. Ved Herluf Winge. Vid. Meddel. fra d. naturk. Foren. i. Kbkvn.

The excellent and methodical Annual Report on the birds 
taken and observed at the Danish lighthouses, accompanied 
by the usual well-drawn map, is again before us (cf. Ibis, 
1899, p. 152). The Report for 1898 informs us that 940 
specimens were received in that year from 33 lighthouses, 
besides notices of others, bringing up the total to 1300 occur¬ 
rences. These are referable to 60 species, of which three 
are new to the list, namely, Totanus ochropus, Corvus frugu 
legus, and Loxia curvirostra. The three species that occurred 
most numerously in 1898 were Alauda arvensis , Sturnus 
vulgaris , and Turdus merula , not usually considered as 
migrants in Denmark. 
32. Witchell on Birds’ Notes. 
[Cries and Call-Notes of Wild Birds : a popular Description of the 
Notes employed by our commoner British Birds in their Songs and Calls. 
With Musical Illustrations. By C. A. Witchell. 8vo. London : 
Upcott Gill, 1899.] 
In f The Ibis/ 1896, p. 582, we gave a favourable notice 
of this author's f Evolution of Bird-Song'; and in pursuit 
of the fascinating subject of bird-lauguage Mr. Witchell 
has now produced a little book in the popular style supposed 
to be suited to the tastes of the end of this century. Town- 
birds, Woodland-birds, Upland-birds, and Water-birds form 
the main divisions of the work, and there is plenty of good 
matter in the author's remarks. There will, however, be 
always the difficulty that few persons can go far in agree¬ 
ment as to the rendering of birds' notes ; in fact, their 
unanimity on this subject is rare, while their divergence 
of opinion is often extreme.
