b. Southern Wood Warbler, P. sibilatrix erlang-eri Hart. 



Foreign Names: Italy: Liii verde. Portugal: Folosa. Spain: 

 Mosquita. 

 P. sihilatrix erlangeri Hart. Hartert, Vog. Pal. Fauna, p. 516. 



Breeding Range: Not clearly defined, but probably the countries 

 forming the basin of the Mediterranean in Europe, and N. W. Africa. 



This race, barely distinguishable by the yellower colouring of the con- 

 male, is apparently found breeding in small numbers in the cork woods ^mq ° 

 of S. Spain, though over the greater part of that country it is only 

 known as a migrant, and rarely occurs in Portugal. It also is the 

 representative form in S. France, but specimens from the Pyrenees have 

 not been critically examined. In Italy it breeds in the hilly districts of 

 the N. and Central Provinces, but not in the S., and though it has 

 been recorded in Sardinia, I can find no proof of its breeding there.* 

 In 1909 I met with a single pair which were evidently breeding in S. 

 Corsica, but was unable to find the nest. In the Balkan Peninsula it 

 is found from Dalmatia to Servia, but only occurs on passage in Greece. 

 It is uncertain which form is found in the Caucasus. [There seems little 

 doubt that it breeds in N. W . Africa, from Marocco to Tunisia, although 

 no nests appear to have been recorded.] 



Apparently in their breeding habits the southern birds do not differ Nest, Egg« 

 from those of the northern race.

Breeding Range: Finmark and N. Russia. [Also N. Siberia.] 

 Has occurred at Fair I. and Suleskerry. 



Collett has given an interesting account of the breeding of this ^°^' 

 bird in Finmark (Ibis, 1886, p. 217). He found it nesting in scattered Europe. 

 pairs among the stunted birch woods along the valleys of the larger 

 rivers flowing into the Porsanger, Tana and Varanger Fjords. In N. 

 Russia it occurs along the Murman coast of the Kola Peninsula, and 

 has been obtained on the N. shore of L. Onega, while Moves also met 

 with it breeding in the Onega valley. Eastward it is found in the 

 valleys of the Dwina, Mezen and Petschora and apparently reaches the 



* Probably Brooke's note in the Ibis for 1873 refers to BonoUi's Warbler, as 

 Bonomi does not mention the Wood Warbler
