the autumn migration, which consisted chiefly of young birds, was not small in Attica, but that 

 it was unknown in what part of Europe they bred, no instance of its breeding in Greece having 

 been recorded. When on my entomological excursion to Rentzicki, I saw and heard the first of 

 these Hawks late in April last year ; they flew over a large and beautiful garden, filled with old 

 trees, and surrounded by a high wall, belonging to a wealthy Englishman at Salonica. A few 

 days later I saw two, already paired, in another neglected garden, and on the 25th of May I shot 

 in the forest of Langada an old male. I did not succeed in finding a nest last year, but I shot 

 several newly fledged young in July, and found under a nest in a large oak near Rentzicki a dead 

 bird. This year I was fortunate enough to find nests and eggs. On the 24th of May I went to 

 the nest near Rentzicki referred to above. A stone thrown by my companion made the old bird 

 fly off, and we then procured four fresh eggs. After taking an egg of the Spotted Eagle we pro- 

 ceeded to the other deserted garden where last year I obtained the young birds. Here, after 

 .looking round for some time, we perceived a small nest on the outer branches of a huge lime- 

 tree, and on throwing a stone at it the Hawk flew off. Before climbing the tree we found at the 

 foot of it the shell of a lately destroyed egg. This newly constructed nest was the smallest I 

 ever saw, and contained one egg quite fresh. In the middle of the tree I found the last year's 

 habitation. 



" On Olympus I had not observed any of these Hawks during the spring; and as I was lame 

 I could not undertake any long excursions. About the end of May, however, I saw a pair near 

 Litochoron, which flew to the high oaks in the churchyard of St. George, but did not seem to be 

 breeding there. On the 6th of June I sent my man to the church of St. John, about an hour 

 (four miles English) distant, whence he brought back four eggs of this species. Later on 

 we found it breeding at several places, so that I was enabled to send twenty-one eggs to Mr. 

 Schluter. Beyond the four eggs I procured at Smyrna in 1863, no other eggs of this bird were 

 known until last year, when two eggs were found by Mr. Hodek in Servia, respecting which 

 Mr. Schluter wrote in the ' Zoologischer Garten,' and Mr. Hodek himself gave particulars at the 

 meeting of the K. K. Zool. Botanischen Gesellschaft of Vienna on the 7th July, 1869. Judging 

 from what my friend remarked, and from my own observation, I am convinced that all the short- 

 legged Sparrow-Hawks, which pass Smyrna in flocks, breed in Europe. It is uncertain how far 

 it goes into Russia ; but in Turkey it is said not to be rare. It is easily distinguishable from the 

 Common Sparrow-Hawk by its call-note, which is a loud Ke weJcer, weher, weker, and is uttered 

 both on the 'wing and when sitting, and sounds as if some one were calling ' geh' weg, geh' 

 weg ' (go away, go away). The nest is sometimes placed high, sometimes low ; and generally an 

 old one is made use of. The eggs are four, sometimes three, in number; and the size differs 

 according to the age and strength of the female ; occasionally, also, the form of the egg is elon- 

 gated, and not round. As regards the dirty colour of some of the eggs, I observed that those 

 freshly laid were generally purer in colour, and the incubated ones more dirty ; still I have found 

 incubated ones rather clean, and fresh ones dirty-coloured, and therefore consider that the 

 coloration of the eggs depends more on the cleanliness of the female than on the condition of 

 the interior of the nest. 



" On the 10 th June my servant found a most peculiar sitting of this Hawk's egg, viz. three 

 eggs quite different in size. The first was very large, indeed almost a double-yelked one, the
