34 



birds, and it is believed that several species not given in the list are now 

 attacking it, but, in view of the general belief that birds do not eat hairy 

 caterpillars, care has been taken to secure the most positive proof before 

 inserting the name of any bird in the list. The list is larger than that 

 given of birds attacking any other of the hairy caterpillars, but more 

 attention has been paid to the enemies of this pest. No doubt as many 

 species of birds may be found attacking other hairy caterpillars.

Birds feeding on the Brown-tail Moth Caterpillar (Euproctis Chry- 



sorrhoea, Linn.). 



So far only 29 species of bh-ds have been observed to attack the brown- 

 tail moth. All of these it is believed eat the caterpillars, but the fly- 

 catchers attack mainly the flying moths. Birds appear at times to 

 reduce the initial colonies of these pests to harmless numbers. The 

 English sparrow occasionally eats a few caterpillars or imagoes, but 

 appears to spend more than an equal amount of time in driving more 

 useful birds away from the infested trees.
