170. sticking up out of water often considerable distances at sea. Hawks much over open sea, and lagoons far from land up to 3 miles and even more, a thing Collocalia does not do (Collocalia spod. leucopygia may go 20 yards out over sea occasionally and never much beyond that, Collocalia esculenta uropygialis never approaches within 20 yards of the sea edge, while hawking for food, though both will cross sea in seasonal movements). Hirundo is on all the Loyalty Islands and on Beaupre Island, but is, except on Uvea and certain small areas on other islands, not plen- tiful but pairs are found here and there where suitable nesting material is to be found. True clay being scarce in the Loyalties it finds material for nesting scarce, though nesting sites are exceedingly abundant and very suitable, and has used many unusual kinds of soil Nest and nesting habits are usual, mud nest lined with fibres and feathers on a ledge under an overhang in a cliff or in an open cave (not dark). Eggs 2 to 4, pinkish white with red spots and blotches. Breeding season very long but mostly from September to December. Often 2 broods and possibly more are raised a year I believe. SEA BIRDS:- Apart from a number of species of Sterna and a very rare visiting Larus no sea birds seem to visit the Uvea lagoon, though numbers of ocean-birds fre- quent seas close to the Uvean coast outside the lagoon. Actually within the lagoon I only saw two species of Sterna (Sterna bergil and Sterna sumatrana) but others may visit it. Both these species nest on the western islands of the
