The plumbeous water redstart is a passerine of the Old World flycatcher family found in South Asia, Southeast Asia and China, including Bhutan. It is typically 14cm long, with males averaging 22g and females 18.8g. Males are slate blue with a rusty-red tail, while females are pale grey with a white rump; the common name refers to the colour of lead (Wikipedia, general species account).
It is very protective of its habitat and extremely confrontational to any trespasser on its territory. To catch flies over rivers, it flies vertically until at least 20 feet above the water, then glides down in a spiral back to the same place. The source read gives no breeding information, so none is stated.
