Distribution. A common but uncertain visitor to the eastern parts of the Empire. This species has been observed in Sadiya, Dacca, Cachar, the Khasi hills, Manipur, Pegu, and Tenasserim, and there are specimens from all these parts in the British Museum. It has been obtained during February, March, April, May, and June ; and it may breed on or near the eastern borders of Assam and Burma. It occurs in Eastern Siberia and Kamtschatka and probably has a very wide range. Some specimens of Swallows from Peru and Brazil in the British Museum are perfectly undistinguishable from H. tytleri.
