S»pt.26. 
Hoard one but the majority have left here. They 
pass the day resting in the thick foliage of the maples, 
standing most of the time on one log with the other drawn 
up under their feathers. Their sight is very nearly as 
quick as their hearing, and it is useless to try to ap¬ 
proach one without good cover. I have noticed that 
thay seem to see more plainly in the day than in the 
dark^ as in the day time they will very rarely pass over 
you, but in the evening they will frequently come within 
half a giunshot, although yo'i may be in open sight. 
They may be easily called by imitating their character¬ 
istic cry.
