41. single habitat except one rail which confines itself strictly to swamps. Two other species Nymphicus and Lichmera confine them- selves to two only or a special type of habitat or close about such specialized habitat. Almost all other species show a tend- ency to range into unusual or unnatural habitat. This tendency has probably been increased for two reasons, a colonial or ex- pansion or forcing out influence because of large population, and the unusual form cultivation takes over much of the island. This tendency will be dealt with before dealing with the three above mentioned species and a glance at the map on the following page may help to a clearer picture of the conditions. This map was made from an actual rough prismatic and chain survey made of an area inland from the main north south lagoon side road (motor road) at a point a little north of a half way point between lahnimiha and Wardilla in the south center of the island and is roughly accurate and to scale. This area was chosen because here abouts the swamp had petered out, the coconut area was narrower, garden land was reasonably good and better than the rest of the island, short forest and tall forest could all be got into an a cross section survey of reasonable scale to show all types of above mentioned area in reasonable and nearly equal proportion. Also this was the best area for Nymphicus (and a further map deals with this) and owing to its shape and general layout afforded better chances of checking observations by myself and others. Almost all species were found in the area. Owing to irregular observation from weather, distance from camp and so on the records were not as complete as one would wish but are fairly reliable and constant. The sub maps give more details and dates. It is observable birds venture further into foreign habitat early
