The Hobby i is a seasonal visitant to the plains of Eastern 
Turkestan, where it breeds. It arrivesin the neighbourhood of 
Yarkand in May, but not in any considerable numbers, and 
migrates—it is supposed, towards India—in October, when the 
trees begin to loose their leaves. The nest is usually placed high 
up in poplar trees (Populusalba), generally near mazars. At 
Sulaghz Langar, on the 9th August, a nest of this bird was found 
placed i am a Figda” tree (Hleagnus latifolia) about 20 feet above 
the ground. The nest contained two very young nestlings (one of 
which is noticed above) and the hinder part of the body of a 
young starling—a bird of the year. As there were no starlings 
within at least 15 miles of Sulaghz Langar, the parent bird must 
have undertaken a trip of 30 miles, over the desert and back 
again, to provide its young with a breakfast. The Hobby shot 
at Yarkand in May was holding in its claws a sparrow (P. 
montanus), which it had just captured ; ; and on another occasion 
I saw one hawking dragon flies over some marshy ground.
