LIST OF BIRDS OF BORNEO. 187 
These birds belong to the dark form of Kestrel (Cerch- 
nes japonicus), and are winter migrants to Borneo. 
Tinnunculus moluccensis (Bp.) has been recorded 
from Borneo on the authority of Schwaner. AIl- 
though it is possible that stragglers may visit the 
Southern districts of Borneo, this species has not been 
noticed by any modern aellecion and it is desirable 
that its occurrence should be confirmed before it is 
definitely admitted among the birds of Borneo.
