The rock horned-owl (_Bubo bengalensis_) is of the same size as the fish-owl, and, like the latter, has aigrettes and orange-yellow orbs, but its legs are feathered to the toes. This owl feeds on snakes, rats, mice, birds, lizards, crabs, and even large insects. "A loud dissyllabic hoot" is perhaps as good a description of its call as can be given in words. This species breeds from December to April. March is the month in which the eggs are most likely to be found. The nesting site is usually a ledge on some cliff overhanging water. A hollow is scooped out in the ledge, and, on the bare earth, four white eggs are laid.

The dusky horned-owl (_Bubo coromandus_) may be distinguished from the rock-horned species by the paler, greyer plumage, and by the fact that its eyes are deep yellow, rather than orange. Its cry has been described as _wo_, _wo_, _wo_, _wo-o-o_. The writer would rather represent it as _ur-r-r_, _ur-r-r_, _ur-r-r-r-r_--a low grunting sound not unlike the call of the red turtle-dove. This owl is very partial to crows. Mr. Cripps once found fifteen heads of young crows in a nest belonging to one of these birds. December and January are the months in which to look for the nest, which is a platform of sticks placed in a fork of a large tree. Two eggs are laid.

The breeding season for Bonelli"s eagle (_Hieraetus fasciatus_) begins in December. The eyrie of this fine bird is described in the calendar for January.

In the Punjab many ravens build their nests during the present month.

Throughout January, February and the early part of March ravens" nests containing eggs or young are likely to be seen.

Ordinarily the nesting season of the common kite (_Milvus govinda_) does not begin until February, but as the eggs of this bird have been taken as early as the 29th December, mention of it must be made in the calendar for the present month. A similar remark applies to the hoopoe (_Upupa indica_).

Doves nest in December, as they do in every other month.

Occasionally a colony of cliff-swallows (_Hirundo flavicolla_) takes time by the forelock and begins to build one of its honeycomb-like congeries of nests in December. This species was dealt with in the calendar for February.

Blue rock-pigeons mostly nest at the beginning of the hot weather.

Hume, however, states that some of these birds breed as early as Christmas Day. Mr. P. G. S. O"Connor records the finding of a nest even earlier than that. The nest in question was in a weir of a ca.n.a.l.

The weir was pierced by five round holes, each about nine inches in diameter. Through four of these the water was rushing, but the fifth was blocked by debris, and on this a pair of pigeons had placed their nest.
