Tetanus melanoleucns . 
Concord, Mass. 
1898. At 3.30 p.H. we (W. Deane and I) took the old boat and 
May is. started up river. 1111 "" As we entered the Holt we heard Greater 
Yellow-legs whistling. We soon discoverd them scattered about 
on the meadow on the east side of the river and running the 
boat in shore watched them for half-an-hour or so. There were 
just fifteen of them on this meadow while a solitary bird was 
feeding on the other side of the stream. As we were within 
fifty or sixty yards of the main flock we had a fine chance 
to observe them. One or two birds, apparently acting as sen- 
tinels stood erect and still on the tops of the tussocks while 
the others rambled about through the short grass probing the 
mud for food. When one of the sentinels whistled all the 
other birds raised their heads and stood motionless until the 
alarm subsided. When we finally showed ourselves the flock 
rose and flew off over Dakin's Hill but they returned and 
pitched down into the meadow again a few minutes laxer.
