Nidification. The Red-billed Liothrix breeds through«ut its range between 3,000 and 8,000 feet in almost any kind of forest, pine, evergreen, deciduous, or in secondary growth and heavy scrub- jungle, but it certainly prefers forest of pine or fir with under- growth. Its nest is a neat cup of grass, bamboo and other leaves and moss; the latter material often forming nearly the whole nest, whilst the lining is of fine roots and tendrils. It is generally placed in a fork, tipright or horizontal, or in amongst a few twigs of a bush or bramble, at some height between 2 and 10 feet. It is seldom well hidden and is often very conspicuous. 200 eggs average 21-9 X 16-1 mm. and the extremes are 23-2 X 17-0, i-3-0xl71, 18*9 x 15-2 and 21-4 x 150 mm. In colour they vary from almost pure white to pale blue and the markings consist of sparse spots and blotches of reddish brown with others, underlying these, of neutral tint, generally confined to the larger end and often forming an ill -defined zone. The shape is a blunt, broad oval and the texture is close, hard and glossy, often very highly so. The breeding season lasts from early April to September but most eggs are laid in May and June.
