Tailor Bird
2 of the 6 encyclopedias on this shelf carry an entry for Tailor Bird. Both are reproduced below, so you can see where they agree and where they differ.
Collier's New Encyclopedia (1921)
the Orthotomus sutorius, a small bird about 6 inches long; general color olive greenish; wings brown, edged with green; crown of the head rufous, inclining to gray on the nape; tail light brown; outer feathers narrowly tipped with white; under surface of the body white; legs flesh-colored. The male has the two center tail-feathers lengthened. A native of India, the Eastern Peninsula, China, etc. It is found in gardens, hedgerows, orchards, jungles, etc., sometimes in pairs, sometimes in small flocks, feeding on ants, cicadellas, and other small insects. Its name of tailor bird is derived from its nest, which is enclosed in leaves sewn with cobwebs, silk from cocoons, thread, wool, and vegetable fiber. The nest itself is formed of cotton-wool with fine loose hairs, etc. Eggs 3 or 4; in different nests they are of different colors, some being white, spotted with rufous or reddish-brown, others bluish-green.
Aiton's Encyclopedia (1910)
a warbler of the East Indies noted for the construction of its nest. There are several species. The tailor bird sews together the edges of two green, growing leaves, using the beak for a needle and vegetable fibers for thread. Sometimes a dead leaf is sewed to a green one. Sometimes the edges of a single large leaf are brought together. In this way a swinging pouch is formed in which the bird builds a comfortable nest of lint or other soft material. The leaves continue to grow and form a perfect screen. The birds themselves are in no way noticeable. They are small birds that wear modest plumage and live chiefly on insects.
What Has Changed in the Last Century
The behaviour both accounts describe has held up: the common tailorbird really does pierce leaf edges with its bill and draw spider silk and plant fibre through to make a cradle, and Collier's 1921 note that eggs in different nests are variously white with rufous spots or bluish-green is still one of the striking things about the species. Closer observation has refined the mechanics — the bird does not knot its thread as a tailor would, but pushes the fibre through and lets the fluffed ends hold like rivets. The bigger change is on paper: Aiton's 1910 description of it as "a warbler" has been overturned, and DNA work has moved Orthotomus out of the Old World warblers into the family Cisticolidae, alongside the African cisticolas rather than the true warblers. Orthotomus sutorius is now called the common tailorbird, remains abundant from India to southeast Asia, and is still a familiar garden and hedgerow bird exactly as Collier's said.
