66 OUR SUMMER MIGRANTS. 



to bough in search of insects, and singing at in- 

 tervals. It is very partial to fruit of all kinds, 

 but at the same time destroys vast numbers of 

 caterpillars, spiders, and aphides. Much against 

 my inclination I have shot a few Garden War- 

 blers in the spring soon after their arrival, for 

 the purpose of ascertaining the nature of their 

 food, and can therefore affirm, from personal 

 inspection, that they destroy quantities of insects 

 which are destructive to foliage. Under the 

 head of Blackcap, I have referred to the nest 

 of the Garden Warbler for the purpose of com- 

 parison, and need only add here that it is gene- 

 rally well concealed, and that, unless the owner 

 is seen near the nest, it is oftentimes not very 

 easy to distinguish the eggs from those of its 

 congener, which have been already described.
