as early as tlie 11th of April — and sing all through, the 

 summer ; I have heard it as late as the 30th of September. 

 Their nests, popularly called " wood-ovens," are alike, and 

 placed in similar situations ; their eggs are of the same 

 size and shape, but those of the Chiff-chaff are spotted with 

 very dark purple instead of rust colour. The Chiff-chaif 

 has been observed in England before the 1st of April ; a 

 few have been seen even in mid-winter, and it is supposed 

 that some habitually remain with us all the year, feeding 

 on winter gnats and the pupae of small insects, but 

 remaining wholly silent. Other names by which it is 

 known are " Chip-chop " and Lesser Pettichaps.

 In its habits it resembles the Stone and Furze Chats, perch-

 rising into the air with most fantastic movements, catching 

 insects on the wing, and either returning to the same twig, 

 or making a short flight to some other convenient bush. 

 Its song is simple and shrill, consisting of the syllables 

 " cha cha cha " several times repeated. This it utters in- 

 differently when perched or on the wing. It keeps quite 

 aloof from human habitations, and is so timid, that on the
