Mixed‐species bird flocks in dipterocarp forest of north‐central Burma (Myanmar)
We studied the bird community in deciduous, dipterocarp forest of north‐central Burma (Myanmar) during December 1994, March 1996, and January 1997 and 1999. Most members of this community participated in mixed‐species flocks. Seventy‐three flocks were encountered during our study, containing 52 spec...
