Corsica the earliest date appears to be the first week in May, and eggs 

 may be found at the end of the month, but in Sardinia Brooke records 

 young on the wing on May 12. Incubation must be usually performed 

 by the hen as Lynes only once found the cock on the nest.

 Breeding Range: The Balkan Peninsula, in the S. and W., the 

 Cyclades and probably Crete. [Also Asia Minor.] 

 Con- Along the rocky coast of Istria, Croatia and Dalmatia, where there 



Europe ^^ cover, this is the first warbler to return in spring, and is a common 

 breeding species. It is also found in the scrub covered foot-hills of 

 Montenegro and the Karst district of Herzegowina, as well as in many 

 of the islands in the E. Adriatic. Probably it occurs also along the 

 Albanian coast, and in Greece seems to be pretty generally distributed in 

 the macchia zone on the bases of the mountains. Kriiper also records 

 it as breeding on Naxos and other islands in the Cyclades, while it 

 certainly visits Crete and probably breeds there. [In Asia Minor Kriiper 

 found it common in summer near Smyrna, but it has only once been 

 recorded from Cyprus, and has not been found breeding in Palestine.] 

 Nest. Resembles that of the previous race, and like it is placed in thick 



bushes, sometimes quite close to the ground, and at other times a foot 

 or so above it. 

 ERgs. Usually 4 or 5, much resembling those of the "W. form, but in the 



greenish type the markings are rarely dark and are generally evenly dis- 

 tributed, while the fine grey shell markings are characteristic. Erythristic 

 types eccur not infrequently but are less boldly and handsomely marked 

 than the finest Spanish eggs. 

 Breeding Kriipcr oucc fouud eggs on April 20, but the more usual time is 



Season. f^.Qjj^ ^j^g beginning of May onward till early in June.
