 with blackish and-brownish blotches. 



HABITS. 



Owing to their northerly distribution and the lack of Observation 

 ofthose who have collected them in their summer home, we know but

 bers of them swarm along both coasts, they being outnumbered possi- 

 bly only by the Least Sandpipers. Flocks of fifty to one hundred in- 

 dividuals are of common occurence during September and October 

 when their migration is at its height, and they are killed by the thous- 

 and and sent to market by gunners all along the coast. As an article 

 of food they are little to be desired owing to their small size and they 

 are so common, so tame and fly in such compact flocks that their capt- 

 ure is anything but exciting yet men will devote their whole time to
