All passerine birds which have hairs springing from the back of the head, and of which the tarsus--the lower half of the leg--is shorter than the middle toe, plus its claw, are classified by scientific men as members of the sub-family Brachypodinae, or Bulbuls. This classification, although doubtless unassailable from the standpoint of the anatomist, has the effect of bringing together some creatures which can scarcely be described as "birds of a feather." The typical bulbul, as exemplified by the common species of the plains--Molpastes and Otocompsa--is a dear, meek, unsophisticated little bird, the kind of creature held up in copy-books as an example to youth, a veritable "Captain Desmond, V.C." Bulbuls of the nobler sort pair for life, and the harmony of their conjugal existence is rarely marred by quarrels; they behave after marriage as they did in the days of courtship: they love to sit on a leafy bough, close up against one another, and express their mutual admiration and affection by means of a cheery, if rather feeble, lay. They build a model nest in which prettily-coloured eggs are deposited. These they make but little attempt to conceal, for they are birds without guile. But, alas, their artlessness often results in a rascally lizard or squirrel eating the eggs for his breakfast. When their eggs are put to this base use, the bulbuls, to quote "Eha," are "sorry," but their grief is short-lived. Within a few hours of the tragedy they are twittering gaily to one another, and in a wonderfully short space of time a new clutch of eggs replaces the old one. If this shares the fate of the first set, some more are laid, so that eventually a family of bulbuls hatches out.
