Hab. — Throughout India and Europe. In Sind the Mohannas or 

 fishermen use this species as a decoy in the capture of wild fowl. Each 

 boat has usually from 5 to 10 birds. Their eyelids are sewn up, and 

 they stand motionless on the cross bar of the rudder gear or perched 

 along the edges of the boat. They are fed daily, and during summer, 

 when the occupation of wild fowl catching has ceased, serve the 

 fishermen as food in the absence of any thing better.
