their nests are consequently either less vahiable, or, in some kinds. 

 not worth collecting. All lay two white, very elongate cylindrico- 

 ovate eggs, and make their nests in caves. During the day the 

 birds hunt about for insects, frequently travelling great distances 

 for the purpose ; Jerdon relates how the birds at Vingorla Rocks 

 did not return to their roosts till 9 p.m., having been away all day. 

 The flight is rapid. Xone, so far as is known, are truly migratory, 

 though they wander over considerable distances. The genus 

 inhabits the greater part of the Oriental and Australian regions.
