Birds of Celebes: Falconidae.

resident birds of prey in those parts of the island”. Mr. Whitehead also marks 
it as a migrant in Palawan ( 20 ). Abbe David states that it breeds in the moun- 
tains near Peking, though it appears not to be plentiful in China ( 5 )\ further 
south, it passes through the Lower Aangtse country, as Mr, F. W. Sty an writes, 
“on migration in March and April. A good number travel together, and remain 
a week or so among the hills on their way; they seem to avoid the plains” ( 22 ). 
Apparently the species is resident, or some remain to breed, in the Philippines, 
an egg, which appears to belong to this species, having been obtained in Min- 
danao by Schadenberg and Koch ( 10 ). The following recorded dates afford 
fairly conclusive evidence that this Hawk descends into the East India Archi- 
j)elago at the beginning of the cold in the northern hemisphere; whither they 
take their departure again with the returning S. W. monsoon.

From the above list of about seventy specimens, furnishing all the re- 
corded dates which we have been able to find for specimens obtained in these 
islands, it will be seen that every one was obtained between October and April, 
except Dr. Steer e’s notice from Luzon, the northernmost island of the Philippines, 
which furnished one or more in July. Its prey consists probably almost ex- 
clusively of reptiles, amphibia and insects which become scarce or quite dis- 
appear in the northern parts of its range on the approach of winter; hence the 
motive for the autumnal migration.
