The Weaver-bird (Ploceus Baya, Blyth) is called (in Selangor) Burong Tempua or Chiak Raya. It is said to use only the long jungle grass called lalang for making its nest, which latter is called buah rabun, and is used by the Malays for polishing sheaths and scabbards. When an infant keeps crying, one of the parents takes the weaver-bird's nest, reduces it to ashes, and fumigates the child by thrice moving it round in a circle over the smoke. Whilst doing so, the parent either stands up with the right toe resting upon the toe of the left foot, or else squats upon the left heel, bending the right knee, and saying, 'As the weaver-bird's young in its nest, so rest and weep not' (Bagimana anak tempua dalam sarang-nya, bagitu-lah 'kau diam jangan menangis). To the above I may add that besides the ordinary bottle-shaped nest, the weaver-birds also occasionally make a hood-shaped, or rather a helmet-shaped nest, which is alleged by the Malays to be the male bird's 'swing' (buayan). This 'swing' resembles the upper half of an ordinary bottle-shaped nest, with a perch across it, which latter is also woven of grass. On the walls of the swing, just over each end of the perch, is a small daub of clay. The Malays allege that the male bird swings in it while the hen bird is sitting, and that the young too 'take the air' in it as soon as they are able to fly so far. Into the two daubs of mud over the perch the male bird (say the Malays) sticks fire-flies to give itself light at night. "The King crow [247] is called by the Malays the Slave of the Monkeys (Burong hamba kra). It is a pretty, active, noisy little bird, incessantly flying about with its two long racquet-shaped tail feathers fluttering after it. They say that when it has both of these feathers it has paid off its debt and is free, but when it is either destitute of these appendages, or has only one, it is still in bondage. "The Gray Sea-eagle [248] is called Burong hamba siput 'the Slave of the Shell-fish,' and its office is to give warning by screaming to the shell-fish of the changes of the tide, so that they may regulate their movements, and those species which crawl about on the mud at low water may know when to take refuge in the trees and escape the rising tide, or when the tide is falling, that they may know when to descend to look for food. "The Burong demam, or 'Fever bird,' is so called from its loud, tremulous note, and the Malays say that the female bird calls in its fever-stricken voice to its mate to go and find food, because it has fever so badly that it cannot go itself. This bird is probably one of the large green barbets. The note is often heard, and doubtless the bird has been collected, but it is one thing shooting a bird and another identifying it as the producer of a certain note.
