Notes on the Ornithology of Siberia. 419 



there is a stick on which it can perch it may always be seen, 

 looking, I presume, after the eels. It is a very late breeder, 

 not hatching till the beginning of June. The nests are, for 

 the most part, very close together ; and as soon as the young 

 can fly the whole colony suddenly disappears, and is not seen 

 again till the next spring, arriving, so far as I could learn, 

 a little later than the Cormorants, at the end of April. I was 

 surprised to find the Common Tern breeding in these lakes, 

 and no trace whatever of the White-winged Black Tern, so 

 common on the coast, and of the Whiskered Tern, which 

 would certainly be found in such localities in Algeria or 

 Tunis. 



I fear these notes must have exercised the patience of those 

 readers who have got so far as this. But I crave their indul- 

 gence, reminding them that, however absorbing the interest, 

 historical and archaeological, of these regions, they are neither 

 fresh fields nor pastures new to the naturalist, though even 

 here the nesting-places of the Bald Ibis and the Darter may 

 afford some inducement to younger and more energetic 

 travellers to follow in our steps and make amends for our 

 deficiencies. 



XXXI. Further Notes on the Ornithology of Siberia. 

 By HENRY SEEBOHM. 



SINCE my last notes on the ornithology of Siberia (Ibis, 1880, 

 p. 179) I have received three small collections of birds from 

 that country, two from my collector in Krasnoyarsk, Mr. 

 Kibort, and one from Samarcand, the latter sent me by Dr. 

 Staudinger, of Dresden. Among the examples contained 

 in these collections are some of unusual interest. 



FALCO BABYLONICUS. 



A fine example of Gurney's Falcon from Samarcand is 

 dated 5th March. 



FALCO SUBBUTEO. 



Mr. Kibort has sent me an adult male Hobby and bird of 

 the year from Krasnoyarsk.
