This Tailor-Bird only enters our area in the extreme South of Tenasserim. Its nests have been taken by Hopwood and Mackenzie at Victoria Point and Mergui, but they have not recorded anything about them. It also breeds in the Malay Peninsula, Borneo and the extreme South of Siam North as far as Bangkok, where both Herbert and Williamson took many nests. The former records, that “this bird is little known in Bangkok, which, however, is not surprising, as its haunts are confined to the fruit-gardens, where it appears to prefer the quiet and shade of the thick undergrowth to parading itself in the compounds like the Malay Tailor-Bird. This natural shyness keeps it very much out of evidence, though its general similarity to the common Tailor-Bird would still prevent any but an enthusiast from recognizing it. Its note is a sweet- sounding trill, ‘kr-r-r-i,’ and is in contrast to the shrill ‘too-whit’ of its noisy cousin. When once this note has been recognized it may be regularly heard in the fruit-gardens, and I have often heard it on the Bangkok side, though it is more common on the Western side of the river, due, of course, to the much larger area of suitable surroundings.
“The nest is identical with that of the Malay Tailor-Bird but, so far as my experience goes, the eggs are slightly brighter in colour, with less of the washed-out appearance, than those of the previous species, only I have not seen sufficient numbers to say whether this is constant or not. The four nests which came under my close observation were in the Bansakai fruit-gardens and were found in June and July 1914 ; the parent birds were in all cases identified and watched by me through field-glasses. There is no variation in size or number of eggs laid by this bird from those of the previous species.”
A series of eggs given to me by Herbert and Williamson were all in clutches of three or four and were all taken between the 7th June and the 12th July. All the clutches are blue, rather bright in tint, except for one clutch of three white eggs spotted with pale rusty.
Twenty-one eggs average 15.6 x 11.6 mm. : maxima 16.8 x 12.1 and 16.0 x 12.3 mm. ; minima 14.5 x 11.0 and 15.2 x 10.9 mm.
