Breedincr Rano-e: Corsica and Sardinia, where it is an abundant 

 resident, breeding even in the coast districts as well as in the mountains. 

 According to Arrigoni it is probably also this form which breeds in the 

 mountains of N. Italy. In Corsica Whitehead describes it as usually nesting 

 in arbutus trees. The nest is built of grass stems, lined with feathers 

 and is rather rudely constructed. The breeding season appears to vary 

 with the altitude, for Whitehead found young on April 29 on the coast, 

 while in the hills many nests were still empty at the end of May. Average 

 of 4 eggs in Tring Museum: 16.72X12.75 mm.. Max. 17.7X13 mm., 

 Min. 16X12.5 mm. (Hartert, in litt).
