THE BIRDS OF SOUTH-WEST AND PENINSULAR SIAM. 1 03 



The Marsh Harrier was common on the rice fields bordering 

 the upper readies ol" the Pakchaii l^^stuaiy ; we did not meet with it 

 elsewhere. In the winter, in suitable open spaces, it is fairly abund- 

 ant as far south as Kuala Lumpur.

The northern race of the Crested Goshawk differs from the 

 typical Sumatra bird in its larger size and in having the breast of 

 the male duller, less reddish. The wings of two nearly adult 

 Sumatran birds measure 198 and 216 mm.; the second, though sexed 

 male, is probably a female. A nearly adult male from Temengoh, 

 N. Perak, is 202 mm,, and a male from Bandon 227 mm. 



The sexes are nearly similar in colour, but males appear to 

 have the dark marks on the breast and belly paler than in the females.
