NIDIFICATION. 259 



About the middle of June the female lays from two to 

 three, though occasionally four eggs. These are nearly oval 

 in form, of a yellowish-white colour, and marked with larger 

 and smaller spots and blotches, which at the thicker end 

 nearly join. They are about two inches three lines in 

 length, by one inch six lines in breadth. 



The osprey, like the sea-eagle, migrates. He leaves the 

 Scandinavian shores at the commencement of the winter, 

 when the lakes and rivers freeze, and returns in the spring 

 when the ice breaks up. 



Kjaerbolling includes three other species of eagles in the 

 Danish Fauna namely, the Keiser-Orn, or Imperial Eagle 

 (Falco imperialis t Bechst.), a southern bird, which has been 

 observed in Jutland; the Skrig-Orn, or Screeching Eagle 

 (Falco n&vius, Gmel.) the proper home of which is the 

 south and east of Europe, and a large portion of Asia 

 shot, in one instance, near the town of Schleswig ; and the 

 Europaisk Slang e-Orn, or European Snake-Eagle (Falco 

 brachydactylus, Temm.), belonging to southern Europe, 

 which he describes as exceedingly scarce in Denmark. He 

 says, moreover, that the questionable species, the Hvit-hoved 

 Hav-6rn, or White-headed Sea-Eagle (Falco leucocephalus, 

 Temm.), which has hitherto only been found in North 

 America, has been killed in the country. 



Though here somewhat out of place, it may be proper to 

 mention, that the Vultur cinereus, Linn., has in several 

 instances been shot in Schleswig and Holstein.
