, the baya flies away
and thus strips off a narrow strand. Sometimes the strand adheres to
the main part of the blade at the tip so firmly that the force of the
flying baya is not sufficient to sever it. The bird then swings for a
few seconds in mid-air, suspended by the strip of leaf. Not in the
least daunted the baya makes a fresh effort and flies off, still
gripping the strand firmly. At the third, if not at the second
attempt, the thin strip is completely severed. Having secured its
prize the weaver-bird proceeds to tear off one or two more strands and
then flies with these in its bill to the nesting site, uttering cries
of delight. The fibres obtained in this manner are bound round the
branch from which the nest will hang. More strands are added to form a
stalk; when this has attained a length of several inches it is
gradually expanded in the form of an umbrella or bell. The next step
is to weave a band of grass across the mouth of the bell. In this
condition the nest is often left unfinished. Indians call such
incomplete nests _jhulas_ or swings; they assert that these are made
in order that the cocks may sit in them and sing to their mates while
these are incubating the eggs. It may be, as "Eha" suggests, that at
this stage the birds are dissatisfied with the balance of the nest and
for this reason leave it. If the nest, at this point of its
construction, please the weaver-birds they proceed to finish it by
closing up the bell at one side of the cross-band to form a receptacle
for the eggs, and prolonging the other half of the bell into a long
tunnel or neck. This neck forms the entrance to the nest; towards its
extremity it becomes very flimsy so that it affords no foothold to an
enemy. Nearly every baya's nest contains some lumps of clay attached
to it. Jerdon was of opinion that the function of these is to balance
the nest properly. Indians state that the bird sticks fireflies into
the lumps of clay to light up the nest at night. This story has found
its way into some ornithological text-books. There is no truth in it.
The present writer is inclined to think that the object of these lumps
of clay is to prevent the light loofah-like nest swinging too
violently in a gale of wind.
Both sexes take part in nest-construction. After the formation of the
cross-bar at the mouth of the bell one of the birds sits inside and
the other outside, and they pass the strands to each other and thus
the weaving proceeds rapidly
