hairs, but no feathers. Occasionally it is built among ferns or growing 

 plants at some little distance from the ground. The song of the male 

 is distinctive : it resembles that of the Wood Warbler to some extent, 

 but is shorter, consisting only of 3 or 4 notes, constantly repeated, 

 without the long drawn 'Whiou, whiou', which the Wood Warbler 

 introduces at intervals. 

 Eggs. Usually 5 or 6, sometimes only 4 and rarely 7 in number. They 



are much like those of the Wood Warbler, being thickly spotted with 

 dark liver brown of different shades, sometimes with a violet tinge, on 

 a white ground, with little or no gloss. 

 Breeding jj^ Central Europe it is a late breeder, and eggs may be found in 



Season. 



the last 10 days of May and early in June, but in S. Spain the season 

 is somewhat earlier, probably about the second and third weeks in May. 

 Tristram took eggs in Algeria between May 20 and June 4, but apparently 

 has not recorded them in his notes on Algerian ornithology. Only one 

 brood is reared, but second layings may be found late in June occasionally. 

 Incubation lasts about 13 days.

Breeding Range: The mountains of the Balkan peninsula: possibly 

 also Bukowina, Transsylvania and the Crimea. [Also Asia Minor, 

 Palestine and probably Cyprus.] 

 Con- This is the only Phylloscopus which is known to breed in Greece. 



Reiser describes a nest found by him with young on May 26. 1898 as 

 the first record for Greece, but Kriiper took eggs as far back as May 

 10, 1880, not far from Athens and also in the Parnassus. Its range is 

 evidently very imperfectly known at present, for it is not recorded by 

 Mac Gregor from Macedonia or by Reiser from Bulgaria or Montenegro 

 although Kadich describes it as common in the warmer valleys of 

 Herzegowina. It has occurred in E. Hungary in August and probably 

 breeds in Transsylvania. It is also said to breed in Bukowina and has 

 been recorded from the Crimea. [In Asia Minor it is tolerably common, 

 and breeds in Palestine, and possibly also on Cyprus.] 



Probably in its breeding habits it does not differ from the western 

 race. The eggs are apparently laid in Greece about May 10. Average 

 size of 6 Greek eggs, 15.53 x 12.55, Max. 16.3 X 12.6, Min. 14.5 X 13 

 and 16.2 X 12.2.
