Like most other tragopans, Cabot’s tragopan primarily forages on the forest floor for ferns, roots of herbaceous plants, stems, leaves, buds, flowers, seeds and fruit, and occasionally small invertebrates (7). Leaves and fruit of Daphniphyllum macropodum are a particularly favoured food (4) (7).
The breeding season is from early March to May (2), when males can be heard calling at dawn from within their territories, and observed performing spectacular courtship displays (6) (7). A nest of leaves, grasses, mosses and feathers is constructed in trees or possibly on the ground, although an abandoned nest of another species is frequently adopted, into which a clutch of two to six eggs are laid and incubated by the female for around 28 days (6) (7). After hatching, the female and chicks stay in the nest for three days without feeding, before flying to the ground to forage within her feeding territory, and remain together for the whole winter (7). Occasionally, flocks of two to three families may gather together until the following spring, and are sometimes joined by males at the end of autumn or in winter (6).
