(1697) Glaucidium brodiei tubiger (Hodgs.).
THE EASTERN COLLARED PIGMY OWLET.
Glaucidium brodiei tubiger, Fauna B. I., Birds, 2nd ed, vol. iv, p. 451.
The Eastern subspecies of Pigmy Owlet extends from Sikkim and Eastern Nepal to Assam, Manipur, the hills of Burma to Tenasserim, the Malay States, China and Formosa.
Like the last bird, this little Owl keeps very closely to dense forest, preferably to evergreen ; but I have known it to select a tree for breeding purposes in a patch of cultivation or standing by itself in grass-lands on the edge of forest. Always, however, even when the nest-hole is in a bare rotten stump, there is sure to be a big tree with very dense foliage alongside in which the birds can hide when not sitting on the eggs. Often the hole selected is one high up in a tree, so thickly covered with leaves that it is impossible to see where it is, and even the bird, as it sits continually uttering its little call of four whistles, cannot be detected. Any description of hole suffices as a nest-hole. Occasionally it may be one large enough to contain a Goose and its eggs, sometimes it is a small natural hollow only a few inches across and, often, it is the deserted nesting-tunnel of a Woodpecker or Barbet. Just as the nest-hole varies so does the height at which it is placed, I have taken the eggs from a huge hole in a dead stump of a tree not 5 feet from the ground, and I have taken others from Barbet-holes 30 and 40 feet up in trees.
These little Owls, though so tiny, are very pugnacious, and will often oust Barbets and Woodpeckers, bigger and heavier than themselves, from holes they wish to secure for their own domestic purposes, occasionally killing and eating the rightful owners before tailing possession.
They make no nest of any kind, but very often there is a thick mat of pellets and remains of insects under the eggs, as, like most Owls, they return each year to the same hole.
The nesting season is April and May and, more rarely, early June A few birds lay in the end of March, and I have taken eggs as early as the 21st of March and again as late as the 2nd and 3rd July.
Like the preceding bird, the present one lays from two to five eggs, the normal number being three or four. These, as so often occurs among the Owls, are laid at irregular intervals, and in a brood of five young ones I have seen two beginning to show wing and tail quills, two comparatively large balls of snow-white down and the fifth a tiny powder-puff about the size of a golf-ball and yet looking ludicrously large when compared with its parents.
Twenty-five eggs average 28.0 x 23.5 mm. : maxima 29.1 x 25.2 mm. ; minima 26.5 x 22.0 mm.
Both bird incubate or, at all events, both may be caught inside the nest-hole. They are the gamest of little birds, and refuse to leave their eggs or young until forcibly ejected, growling, hissing savagely and fighting to the last.
