“This little Gull is more often found in flocks than our other species, 
and is frequently seen flying over swamps and plowed fields search- 
ing for worms and insects; but it is usually met with on the lakes and

that species” (Eaton). 
It may sometimes be seen in active, fluttering groups feeding in 
our harbors.
