THE BURMESE BROWN HAWK-OWL.

The Burmese Brown Hawk-Owl ranges from Assam South of the Brahmapootra, through Burma, to Tenasserim and possibly, according to Kloss, to the North of the Malay States. East it is found through the Shan States to North and Central Siam and, probably, South-West Siam. It is to be found from the foot-hills up to about 4,000 feet, but more often between 2,000 and 3,000 feet than higher or lower.
This is rather more of a forest-haunting bird than the Western race but, like it, may be found in almost any kind of country, and
I have more than once taken its nest in trees standing absolutely in the open. Its favourite site seems to be, a hole in some dead tree standing in cultivation with forest all round, or else in the half¬cleared spaces round some of the Khasia villages. Other holes I have seen occupied by these Owls have been in thin forest of deciduous trees, odd trees standing in scrub- and bamboo-forest and again a few in the depths of evergreen forest but, in such cases, nearly always near some open glade or stream.
There is, of course, no nest beyond the usual pellets found in old nesting sites, and any sort of hole seems to suffice for the deposition of the eggs. Most are of some size and none are at any great height from the ground, more being under rather than over 20 feet, while I have taken eggs from as low down as 6 feet from the ground.
One nest I found had been previously occupied by a Roller (Coracias b. affinis), and the Owl was sitting on two eggs of its own and one of the Roller’s. On the ground numerous Rollers’ feathers in and below the nest raised serious suspicions, but not proof, of what had happened for, under most circumstances, these Owls are almost exclusively insectivorous.
As usual, they are good fighters in the protection of their household penates, and may easily be caught on their nests, and we have thus caught both males and females when sitting.
The breeding season is from the end of March to the first week in June, and the birds are not double-brooded.
Three to five eggs are laid, the latter number being exceptional.
Fifty eggs average 35.1 x 29.5 mm. : maxima 38.0 x 31.6 and 37.0 x 32.0 mm. ; minima 33.1 x 29.3 and 34.3 x 28.0 mm.
An egg laid and marked in pencil on the 3rd April hatched on the 27th, so in this case we have the exact number of days, i.e., twenty-four, occupied in incubation. Both sexes assist in incubation.
