Myophonus caeruleus is a medium-sized passerine bird of important ecological,scientific and so-cial value,with unique cave-dwelling habits in Xiangxi Prefecture,Hunan Province.A combination of field investigation and portable automatic infrared video recording was employed to explore the main fac-tors influencing the nest-site selection and characteristics of breeding behavior of this species.The major results are as follows:The main factors influencing the choice of nest sites of Myophonus caeruleus are spatial location and microclimatic environment.The nests are bowl-shaped,composed of four layers,and the dominant nest materials included mosses(50％),rhizomes(30％)and leaves(10％)of herbage and lianas.Both female and male birds participate in nesting,and the nesting behaviors primarily include nest-building(68.5％),nest-tidying(13.9％),warning(8.4％)and inspecting(5.7％).Incubation is mainly carried out by the female bird,and the behaviors during the incubation mainly include preening(38.5％),egg-turning(29.3％),nest-sitting(13.2％),inspecting(9.2％)and warning(5.4％).Both the male and female birds raise the chicks together,and the behaviors during the breeding chiefly covere nestling-feeding(38.9％),feces removal(15.8％),nestling-turning(11.6％),brooding(10.9％),pree-ning(9.3％),inspecting(5.3％),and warning(4.6％).
