ON BIRDS FROM MOUNT TENGGER. 45 
numerous flying termites (native name: larons), which ap- 
peared out of holes in the ground and raised themselves 
in large flocks in the air. These larons were pursued by 
several birds, which were flying above the place where 
they appeared out of the holes. Among these birds I observed 
a good many Collocalia, some crows, a couple of Crocopsis, 
a Bhringa remifer and a couple of these kestrels. One of 
these latter birds I shot; the stomach of this example was 
stodged with larons (B. Jacobson).

This bird I shot in the woods; it utters a rather shrill 
ery of two notes, repeated hundred times, while in the 
meantime it moves its expanded tail to both sides (EH. 
Jacobson).
