No. 30. TREE-PIPIT, (x\nthus trivialis.) 



This summer visitor arrives in the south of England early in April 

 and is generally distributed througliout the more wooded portions of 

 Great Britain during the summer months. Its reported occurrence in 

 Ireland is doubtful. The male is generally to be seen perched on the 

 topmost branch of some tree, whence, at short intervals, he rises singing 

 into the air, nsually returning to his starting-point as the song ceases. 

 The food consists of insects and small seeds. The nest is placed on the 

 ground among grass and herbage and formed of moss and dry grass, 

 lined with hair. From four to six eggs are laid and vary greatly in 

 colour and markings.

No. 31. RED-BACKED SHRIKE. (Lanius collurio.) 



This summer visitor arrives in the south of England early in May 

 and is irregularly distributed throughout the wooded districts of 

 England and Wales during the summer montiis. A few pairs occa- 

 sionally breed in the south of Scotland, but from Ireland the species 

 has only once been recorded as an accideutal straggle)-. The food 

 consists of small mammals, birds, lizards, bees and other insects, and 

 from its curious liabit of impaling its prey on thorns, this species and 

 its allies are commonly known as " Butcher-birds." The "larder" of 

 the pair exhibited contained a young Yellow Hammer and a number of 

 bees. The rather large nest of moss and roots, lined with dry grasses, 

 hair, and wool, is placed in a thorn-bush or thick hedge five or six feet 

 from the ground. The eggs are from four to six in number and vary 

 greatly in colour and markings.
