26 FAMILIAR WILD BIRDS. 



small beetles, and caterpillars, all being captured and de- 

 voured indiscriminately. 



In capturing its winged food the movements of the 

 Dartford Warbler are by no means dissimilar to those of 

 the common Whitethroat, this bird also often indulging in 

 short, rapid flights after its prey, and quickly returning to 

 its perch. The flight is jerky and irregular, and seldom 

 indulged in to any great distance ; in fact, the bird is rarely

The peculiarities of this interesting little bird are, 

 however, not very easily observed, for it is extremely shy

 approach is attempted it instantly leaves the more exposed 

 branches for the security and concealment of the denser 

 parts. 



The note is shrill and piping, but of no great volume 

 or variation. Its owner would appear anxious to atone 

 for these deficiencies by continuous repetition, and it may

 to twenty minutes without cessation. It also frequently 

 utters a sort of chattering cry, resembling "Cha, cha,

 quently there is an interweaving of wool. The structure 

 is apparently somewhat loosely put together, but a close 

 examination generally shows it to be far stronger than it 

 appears. Furze bushes are chosen as the most suitable 

 nesting places, and the nest is generally about a couple of 

 feet from the ground. The eggs number four or five : they
