in calling him eccentric, but that there is method in his madness no 
one who studies him closely can doubt. 
Is the odd jumble of whistles, chucks, and caws uttered by one 
bird in that copse yonder, or by half a dozen different birds in as many 
places? Approach cautiously, and perhaps you may see him in the 
air—a bunch of feathers twitched downward by the queer, jerky notes 
which animate it. One might suppose so peculiar a performance would 
occupy his entire attention, but nevertheless he has seen you; in an 
instant his manner changes, and the happy-go-lucky clown, who a 
moment before was turning aérial somersaults, has become a shy, 
suspicious haunter of the depths of the thicket, whence will come his 
querulous chtit, chit as long as your presence annoys him.

This beautiful bird is a lover of well-watered, rather densely grown 
woods. It is a bird of the lower growth rather than the trees, but is not 
a thicket-haunter, and its habit of flitting restlessly from bush to 
bush renders it easily observed. When on the.wing its white outer 
tail-feathers are conspicuously displayed, and, with the striking mark- 
ings of the head, make an excellent field-mark. 
The song of the Hooded Warbler is sweet and graceful. It is sub- 
ject to much variation, but as a rule consists of eight or nine notes. 
To my ear the bird seems to say, ‘‘You must come to the woods, or 
you won’t see me.” Its call-note is a sharp, characteristic. cheep, fre- 
frequently uttered when the bird is anxious for the safety of its nest or 
young, and accompanied by a, flit of the tail, which reveals the white 
outer tail-feathers.
