Habits. The Rufous-chinned Laughing-Thriisli is found in pairs or in small parties of four and five and, like tiie rest of its relatives, haunts undergrowth, scrub and secondary growth, but always in forest or in its immediate vicinity. It is not a noisy bird, but has a large variety of notes, some of which are harsh and loud and some are soft and mellow; its flight, when it can be forced to take to wing, is feeble and ill-sustained, but in clambering about bushes and reeds it is very active and equally so on the ground, where it seeks much of its food, both insect and seed. It is found as low as 2,500 feet, but is most common between 4,000 and 6,000 feet, ascending as high as 8,000 feet.
