In spring the wandering little companies break up, and al><>ut 

 the end of April breeding begins. The nest is placed in a hole in a 

 tree or wall, or wherever a suitable cavity is found. It is loosely 

 formed of dry grass or moss, lined with wool, hair, and a quantity 

 of feathers. Five to eight eggs are usually laid, in some cases 

 as many as twelve and fourteen ; in colour they are like those of 

 the great tit, and, as in the case of that species, the incubating 

 bird sits closely on her eggs and hisses like a snake when interfered 

 with. 



The blue tit is omnivorous in its diet. In summer it feeds 

 principally on caterpillars, aphides, and insects of all kinds, some- 

 times catching them on the wing. At other seasons it eats fruit 

 and seeds of various kinds, buds, flesh, and, in fact, almost anything 

 it can get.
