The Long-tailed Broadbill (Psarisomus dalhousiae) is a species of broadbill that is found in the Himalayas, Southeast Asia, and Indonesia. It is the only bird in the genus Psarisomus. The Long-tailed Broadbill is about 25 cm (10 inches) in length and weighs between 50 and 60 grams. It can be identified by its shrill call.
The Long-tailed Broadbill is a forest bird that lives on insects. It is very sociable and normally travels in large, noisy parties except during the mating season. It builds a pear-shaped nest in a tree. The female usually lays between 5 and 6 eggs that are incubated by both sexes; both sexes also help to feed the young.
The scientific name commemorates Christina Broun, Countess of Dalhousie (1786–1839), wife of George Ramsay, 9th Earl of Dalhousie.
