Dotgurus lentiKinosus . 
Ball's Hill, Concord, Mass. 
1897. 
Late in the afternoon I saw (from my boat on the river) 
Apr.30. 
a Bittern opposite Birch Island. He was standing on the meadow 
at the water's edge. As I approached he crouched and skulked 
off a few yards into the grass, reminding me of an Indian by 
his stealthy gait. After I had passed he stood erect and 
presently "pumped" twice in full view.

Bo taurus lent i«inosus.

At sunset a Bittern was pumping at short intervals in 
May 5, 
the bushy part of the swamp behinds Balli Kill. I thought I 
heard one there on the night of the 2nd. 
May 7. 
Three Bitterns were pumping this evening, two on the 
Croat Meadow, the third in the swamp behind Ball’s Hill where 
I think there is likely to he a nest a little later.
