THE WARBLERS. 295 



The Blue-throated Warbler (Bldhake- Sang are, Sw. ; S. 

 Suecica, Lath.) was exceedingly scarce with us ; as it is 

 indeed in the midland and southern parts of Scandinavia. 

 It is found in Denmark, though sparingly. It breeds most 

 generally in the far north, where by all accounts it is plen- 

 tiful during the summer months. Migrates. 



"This bird," M. Malm tells us, "is the first songster 



within the polar circle ; it is common near to the wooded 



mnks of all rivers and streams, even up to the Icy Sea. 



'owards the end of August, when the period of migration 



ipproaches, it comes near to houses in search of flies and 



>ther insects." 



The song of the blue-throated warbler, which in itself is 

 rery beautiful, strikes one as the more pleasing when heard 

 the wilds and solitudes of Lapland, where there is a 

 it dearth of songsters. It consists of several varying 

 lotes, which are repeated without intermission. 



This bird breeds in the month of June, and makes its 

 lest either in a thick bush growing near to the water, or 

 it may be on the ground itself. The female lays five to 

 six eggs of a uniform pale-green colour, sometimes sprinkled 

 ith nearly undiscernible brown spots; they are six and a half 

 ines in length, and near five lines in thickness. 



The Redstart (Rodstjert- Sang are, or Red-tail Warbler, 

 >w. ; S. Phcenicurus, Lath.) was very common with us, 

 well as all over Scandinavia, from Scania to beyond the 

 )lar circle ; and this both on the coast and the interior of 

 ie country. Migrates. 



The Black Red-tail (Svart Rodstjert-Sdngare, or Black 

 l-tail Warbler, Sw. ; S. Tithys, Scop.). This bird is very 

 rare in Scandinavia, and there are not many instances on
