Mention should also here be made of such species as the Jackdaw and the Starling, which not unfrequently resort to such localities in quest of a nesting site. CONCEALED OR COVERED NESTS 109 Some of the Parrots also nest in rock crevices, whilst some of the Geese make their nests in hollows in sandy clifiFs, as, for instance, the Chloephaga melan- optera of Chili {conf. Ibis, 1897, p. 190). Amongst Passerine birds we have many instances of nest-builders amongst rocks and stones. Such sites are i...n some cases peculiar to entire groups; in others they form exceptions to a very different method of nidiflcation. Amongst the most thorough rock-builders we may first mention the Chats (Turdidse), of which our own Wheatear (Saxicola cenanthe) is a very familiar example. Between thirty and forty species of these birds are known to science. Their nests are remarkably uniform, not only in the manner of construction, but in their situation. The Chats are pre-eminently rock birds; they are birds of the bare, stony hillsides and boulder-strewn plains and desert sands, showing no partiality for arboreal haunts.
