elevation cane vines grow densely and here when these are in seed (a large seed nearly as big as maize seed, indian corn) numbers of Columba are said to gather to feed on the red seeds of the vine. TIDAL LAGOONS and MANGROVE SWAMPS These areas are long and thin but play a large part in the bird life as a feeding ground not only for waders but others also. Towards their sea ends where the rise and fall of tides are still covering and uncovering areas of land or mud flats they are typical tidal arms. More or less clear of bush inlets near their entrances and slowly becoming dotted with mangrove the further up one proceeds. A large bodyof water (and a big area of land is covered) passes in and out and in the shallower upper reaches deep channels like 2 and three ft. deep trenches spread out like fingers. All wading birds and ducks frequent the margins of these. In about the mangroves especially at low tide, Gerygone, (common) Chacities (rare) Miagra (common) Lichmera (fairly common) Lalage (common) Halcyon (common) gather in numbers and feed a great deal. Swifts and swallows are of course exceedingly common these areas being close to their main breeding grounds. Beyond the area of the usual tides rise and fall but still more or less subject to sea water unundation areas of other types of close growing mangroves. During the greater part of the time these swamps are more or less fresh water swamps or brackish. They are irregular, in occurrence and are often completely sur- rounded by narrow strips or fairly wide areas of normal low type forest of teak and other forest trees. Coral outscrops are common in the area and it is on these that forest grow and in the hollows between the mangrove (like a basket willow) grow in dense thickets.
