AUTUMN FOOD OF THE MYRTLE WARBLER 
was seen to take several objects from the branches. In its stomach were 
found 4 bayberries (.64), some caddice-flies (.18), two-winged flies (.03), 
undetermined insects (. 1 1 ) , and a little other undeterminable material ( 03). 
A Myrtle Warbler was seen at 6:30 a. m., September 27, along a brook at 
Durham to catch and eat some small objects among the leaves of willow 
shrubs. The stomach contents proved to consist of three bayberry seeds 
(.61), a lepidopterous caterpillar (.29), a spider, a beetle, and insect eggs (.01 
each), and some remains of insects doubtfully identified as caddice-flies 
(.07). 
On October 3, 1899, five specimens were collected at 12: 30 p. m., at the 
Durham Point bridge. At the time they were all in willows, but they 
appeared to have come in from a pasture to the north where bayberries and 
sweet ferns were abundant. They had eaten the following ratios:
