145. COLLOCALIA ESCULENTA UROPYGIALIS (GRAY):- A common species on the island, but by no means common as Collocalia spod. leuc. during the greater part of if not all the year round. Its habits and behaviour are exactly similar here as elsewhere, this species favouring less open places than other Collocalias, and even hawking much below the treetops in absolute forest areas and generally closer to the ground than others, and seldom visiting really open types of habitat. It does hawk occasionally above treetop level but seldom very far above, and never for very long, periods. Along narrow tracks and road, between scrub or forest, between coconut palms, and low near the ground, being favourite hawking areas. In and above native gardens are also favour- ite places for feeding. It seldom visits open grass paddocks or areas of any expanse. Will hawk amongst coconuts, come to the margin of an open grass area and turn back through the coconuts or along the margin of the grass area, often not going more than 15 feet into the open area. Nest and eggs usual. MAYR QUESTION: Nest under branches of big trees? ANSWER: Yes where sheltered from weather and not subject to water drainage around the limb in wet weather. COLLOCALIA SPODIOPYGIA LEUCOPYGIA (WALLACE):- See notes under Notes of espec. species Zones of Bird Life. HALCYON CHLORIS CANACORUM (BRASIL):- A common species on the island being identical in habits to birds of Mare Is., though it is more plentiful on Uvea than Mare Is. per square mile. Is very common in and about the
