Bonelli's AVarbler is generally distributed throughout the hilly parts con- 

 of the Iberian Peninsula, from Gribraltar to the Cantabrian range and -^°^° ^ 

 the Pyrenees. It also occurs in the hillsides of southern and western 

 France up to about lat 461 on the W. coast, and is said also to be 

 found near Metz and Paris. In Belgium Aplin records meeting with a 

 pair near Dinant, while it is distributed over the whole of the Alpine 

 district, and is especially common on the southern slopes of the Jura. 

 In the Engadine it breeds up to nearly 6000 ft. Northward its range 

 extends into Lothringen, Wiirtemberg, Bavaria and N. E. Bohemia 

 (Riesengebirge). It is found locally in Lower Austria and also in the 

 Tyrol, Styria, Carinthia, etc., and is not uncommon in the hills of N. 

 Italy, but becomes local in the S., and only occurs on passage in Sicily. 

 It is not recorded from Corsica, and only on passage from Sardinia, but 

 is found in the Balearic Isles. [In N. Africa it breeds in the Atlas 

 range up to 5000 ft, and also in certain wooded mountains of Algeria 

 and Tunisia, but has apparently a very restricted range.] 



Less carefully concealed that that of the other Leaf Warblers, the Nest. 



nest is generally built on the ground in a slight depression, and is of 



the type usual in this genus. It is usually placed on a sunny hillside 



wooded with conifers, beeches or oaks, and is built of dead leaves, dry 



grasses, bents and a little moss, lined with fine bents, roots and a few
