BIRDS OF PEASEMARSH 



that nests in the pine trees, usually farther 

 south. Our own Canadian Warbler is one of 

 the most beautiful, its favorite nesting place 

 is on a bank among the roots of old trees or 

 stumps. 



The Warblers are most useful birds among 

 the trees. As so many of the insects that they 

 devour are small and undeveloped, they are 

 not always given full credit for the good they 

 do. They are a family that guard the trees from 

 the ground to the very tip. Some search for 

 insects among the fallen leaves ; others examine 

 the bark of the trunk and limbs for tiny insects 

 that larger birds have missed; others go from 

 branch to branch clearing the leaves of insects ; 

 others catch insects that are flying about the 

 trees. One of the greatest values of these birds 

 is their habit of devouring newly hatched 

 caterpillars and of feeding the larvae of these 

 caterpillars to their young. Since the cater- 

 pillars are the greatest leaf destroyers we have, 

 and as trees cannot breathe without their 

 leaves, the Warblers have a large share in sav- 

 ing them for us. 



We have also watched these tiny birds 

 gathering leaf eating beetles and bark beetles.
