a. ACCIPITRES. 



1. Circus spilonotus Kaup. (Grant, Ibis, 1895, p. 437.) 

 A regular winter migrant to the Eastern Archipelago, but 



not so numerous in the Philippines as the next species. 



2. Circus melanoleucus (Forst.). (Grant, Ibis, 1895, 

 p. 437.) 



The Black-headed Harrier is not uncommon in districts 

 where large grass-plains and open paddi-fields abound. In 

 Luzon most o£ the country is of this nature, and this Harrier 

 finds splendid hunting-grounds. I believe it is a resident 

 species, as I have seen it late in the spring in North Luzon. 

 That C. philippensis Steere, from Negros, is only the female 

 of C. melanoleucus there can be little doubt, for I noticed a 

 perfectly adult male of the latter within 30 yards of me in 

 that island. 



Iris straw-yellow ; bill black, base of lower mandible dull 

 lead-blue ; cere dull yellow ; legs orange-yellow. 



3. Circus ^ruginosus (Linn.). (Grant, Ibis, 1895, 

 p. 438.) 



The Marsh-Harrier is probably only a winter visitant to 

 North Luzon, where it is not uncommon about the swampy 

 rice-fields, in which it finds an abundance of snakes and 

 frogs. Long before I obtained a specimen of this species I 

 had seen stuifed examples of it in a Manila museum. My 

 specimen was obtained on the 20th November, 1894. 



4. AsTUR soLOENSis (Lath.). (Grant, Ibis, 1896, p. 104.) 

 The only specimen obtained by me was shot on the extreme 



north-east point of Luzon, when the northern migration was 

 in full swing. 



Iris hazel ; cere orange ; bill bluish at base, black at tip ; 

 feet king^s yellow. 



5. AsTUR TRiviRGATUs (Tcmm.) . (Grant, Ibis, 1897, 

 p. 212.) 



Met with only in Samar ; though much of our time 

 was spent in the island of Luzon, we failed to obtain this 

 Goshawk there.
