brethren, are feeding their offspring. The 6th February is the
earliest date on which the writer has observed a hoopoe carrying food
to the nest; that was at Ghazipur.

March and April are the months in which the majority of coppersmiths
or crimson-breasted barbets rear up their families. Some, however, are
already working at their nests. The eggs are hatched in a cavity in a
tree--a cavity made by means of the bird's bill. Both sexes take part
in nest construction. A neatly-cut circular hole, about the size of a
rupee, on the lower surface or the side of a branch is assuredly the
entrance to the nest of a coppersmith, a green barbet, or a
woodpecker.

As the month draws to its close many a pair of nuthatches (_Sitta
castaneiventris_) may be observed seeking for a hollow in which to
nestle. The site selected is usually a small hole in the trunk of a
mango tree that has weathered many monsoons. The birds reduce the
orifice of the cavity to a very small size by plastering up the
greater part of it with mud. Hence the nest of the nuthatch, unless
discovered when in course of construction, is difficult to locate.

All the cock sunbirds (_Arachnechthra asiatica_) are now in the full
glory of their nuptial plumage. Here and there an energetic little hen
is busily constructing her wonderful pendent nest. Great is the
variety of building material used by the sunbird. Fibres, slender
roots, pliable stems, pieces of decayed wood, lichen, thorns and even
paper, cotton and rags, are pressed into service. All are held
together by cobweb, which is the favourite cement of bird masons. The
general shape of the nest is that of a pear. Its contour is often
irregular, because some of the materials hang loosely from the outer
