Adult females are considerably larger than males and 
it is possible that mistakes have been made in the sexes 
of two examples. 
Young birds differ from adults in having the abdomen 
much paler tawny ; but the forehead, patches on the sides 
of the head and neck and the checks tawny instead of 
white : also in the colour of the bill and feet. 
The Minangkabau name, stkok bondo, means Munia- 
hawk, because Microhierax preys on Munia maja and other 
species of Munia, especially on the young birds. It also 
feeds on dragonflies and other flying insects. 
The Pygmy Hawk is very common and frequents open 
country, clearings, gardens, and plantations, where it is 
usually seen sitting on a prominent bough or dead branch 
whence it can overlook its surroundings. The bird con- 
tinually nods its head, when it is on the look-out. From 
its perch it sallies out to catch an insect on the wing, return- 
ing to the same spot to devour it. The species is never 
met in the forest. 
Of the specimens from Andalas, an adult male and 
female and the two young birds belonged to a family of 
six, all sitting on the same bough. I brought down the 
two parents and two of the young, but the others escaped. 
After each discharge the birds flew off, returning shortly 
to the same spot.
