 plumage were observed in the same flock. Seeds eppeared to constitute their food. Very simultaneous in all their movements, 

 never having observed a straggler remaining behind after the flock had started ; they are the most absolutely gregarious birds 1 

 ever met with. — (Clark.)

 sometimes bring down twenty or thirty. — (Kennerly.)
