Whilst the female Chiffchaff was hard at work, 

 the male kept on wearisomely reiterating his note 

 first from one branch and then from another over- 

 head. I caught several small, light green caterj^illars 

 and troublesome flies, and placing them on the edge 

 of the nest, knelt down, and waited within five feet 

 of it. By remaining perfectly still until she had

 they called to one another in notes Avhich could 

 be heard at a surprising distance. AVhen near the
