(1668) Otus bakkamoena gangeticus Ticehurst.
THE UNITED PROVINCES COLLARED SCOPS OWL.
Otus bakkamoena gangeticus, Fauna B. I., Birds, 2nd ed. vol. iv, p. 425.
The range given for this race by Ticehurst is Rajputana and United Provinces, and to this I would add Bihar, the birds of which, appear to be nearest this form.
The breeding habits are just the same as those of other races and need no repetition. It is a very common bird in Bihar, where Coltart and Inglis took very fine series of its eggs, giving me a representative set of five clutches. Nine times out of ten it deposits its eggs in holes in Mango-trees in orchards round about villages, and may often be found breeding in company with the Ringed Paroquet ; I have myself found Sitta castaneiventris, the Owl and the Paroquet all breeding in the same Mango-tree within a few feet of one another.
Occasionally this Owl makes use of holes in old factory walls and roofs, but I have never heard of it breeding in inhabited buildings.
The breeding season is from February to April, hut Coltart took a clutch of fresh eggs on the 15th May, possibly a second brood, though this Owl is not normally double-brooded.
The full clutch is three or four eggs, but five are occasionally laid.
Fifty eggs average 33.1 x 28.1 mm. : maxima 35.2 x 28.9 and 35.1 x 29.9 mm.; minima 31.0 x 27.0 mm.
Like those of most Owls, the eggs appear to be deposited at very irregular intervals, so that it is rather hard to determine the exact time taken for incubation. Sometimes the female begins to sit directly the first egg is laid, but at other times not until two or more have been deposited. Probably the time of incubation is twenty-two to twenty-three days, not more, though Witherby gives the period of incubation of the European Scops Owl as twenty-four to twenty-five days.
