The Pied Harrier passes in A})ril and May and again from 

 the end of August to perhaps the middle of October. It is 

 by far the most abundant of all the Harriers in this part of 

 Chihli and is often seen travelling in parties. Adults are 

 quite common. 



On the 25th of September, 1912, while out duck-shooiing 

 at the marshes, I chanced on a number of Harriers which 

 were fishing (for frogs presumably) after sunset by moon- 

 light. 1 (lid not ascertain the species. On the 12th of 

 September, 1915, I noticed another such gathering of 

 Harriers at the marshes at sundown. The birds on this 

 occasion were, I believe, Pied Harriers. 



This Harrier was noticed by me on tlie plains near 

 Newchwang during June. 



169. Circus aeruginosus (L.). 

 Circus ceruyinosas D. & 0. p. 30. 



The Marsh Harrier is extremely abundant during Sept- 

 ember and until well on into October. 



My first list of Chinwangtao bir.ls (Customs Decennial 

 Reports, 1902-11, Chinwangtao Report, p. 173; Shanghai, 

 1913) mentions C. spilonotus, but 1 find that I have no 

 certain records of this bird and therefore omit it in the 

 present paper.
