In some of its actions it resembles the Willow Wren, for it seems constantly in motion, hopping from bough to bough in search of insects, and singing at intervals. 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 Warblers 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 comparison, and need only add here that it is generally 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. [Illustration: Decorative glyph] [Illustration: COMMON WHITETHROAT] THE COMMON WHITETHROAT. (_Sylvia cinerea._) Far from leading a retired life like the last-named bird, the Whitethroat forces itself into notice by its noisy chattering and repeated sallies into the air. We cannot walk along a country lane in May without being reminded at every twenty yards of the presence of this demonstrative little bird. With crest-feathers erect and half-extended wings, it bustles in and out, gesticulating loudly, and seems to live in a perpetual state of excitement.
