These Swallows are common in the island ; they generally 

 perch upon dead twigs of trees, from which they look out 

 for their prey, and darting upon it, and returning to their 

 station, something in the same way as the common European 

 Flycatcher does ; the Swallow, however, takes rather a 

 longer flight than the Flycatcher. They breed in fissures 

 of rocks, and the nest is composed of mud, and lined with 

 feathers.

 the nape gradually passes into a greenish brown, which is the colour

 feather having a stripe of vivid ultramarine blue running down the 

 shaft. 



Wings, covers and scapularies sea-green with blue reflections ; 

 spurious wings black edged with blue ; primaries above black 

 edged with blue on the outer webs ; on the first primary, on the 

 inner web, at about a third of the feather from its base, is a broad 

 band of light changeable blue or green, according to the light in 

 which it is held; this band is continvied on the six nest primaries on 

 both the inner and outer webs, and on the eighth is a single spot of 

 the same, colour on the outer web alone ; the inner webs of the 

 under side of the primaries are for the most part broadly margined 

 with rich deep blue.

 at the basal part ; below, black, with the inner webs broadly mar-
