THE BENGAL BROWN FISH-OWL.

The breeding range of this Owl extends from Bengal and Orissa, through Assam, Manipur and all Burma, to the Malay Peninsula.
So far as is known the eggs of this race of Fish-Owl are laid in places very similar to those selected by the other races. In Bagoolah, 60 miles from Calcutta, Parker obtained two fresh eggs from a Vulture’s nest built on the top of a lofty Pepul-tree, Cripps in Faridpore found its eggs in a large hollow in a dead stump of a Mango-tree. Oates in Pegu found two young birds in a hollow between the great branches of a tree at about 10 feet from the ground, while Hopwood took two eggs from a hole in a cliff on the Lower Chindwin.
Round about Dacca a favourite nesting site was in the small ruined mausoleums, of which there were many round the race¬course and golf-course and also round the Nawab’s Palace. Under the domes of these were generally a stone roof over the room below, and here the birds deposited their eggs, finding their way in and out through the breaches in the masonry. The birds seemed to select those oyer which some parasitic Fieus was growing, and I found no nests in the mausoleums, equally broken down, over which no vegetation grew.
The breeding season generally is from November to February, but they sometimes breed a good deal later, the fresh eggs found by Hopwood being taken on the 2nd April.
Two eggs form the normal clutch, but I found three eggs twice in Dacca.
Ten eggs average 58.4 x 48.9 mm. : maxima 60.2 x 50.1 and 58.0 x 53.0 mm. ; minima 56.7 x 47.8 and 59.9 x 47.5 mm.
The birds return each breeding season to the same nesting site for many years in succession, as I found great piles of pellets and animal remains in some of the nesting places I saw in Dacca. The birds sat close, but never attempted any defence of their eggs or young.
