INTRODUCTION
WETLANDS
etlands include a range of watery habitats, from the
Wedge of the sea to lakes, reservoirs and lagoons,
rivers, marshes, and seasonal floods.Water means just one
thing to birds – abundant food, in the form of fish,
invertebrates, and plant material.Wetland birds exploit
these food stocks in innumerable ways: swimming on or
under water, wading into it, flying over it, or living in
the dense, upright stems of plants found alongside the
edge. Unfortunately, many of these habitats have been
reduced by centuries of drainage and some wetland
habitats and their birds are under serious threat today.

WETLAND FEAST
Flood plains and low-lying river valleys flood during
heavy rainfall. Worms, insects, seeds, and other
vegetable matter float to the surface or are washed
up at the water’s edge for waterfowl to feed on.

depend on areas of reed growing up from the shallow
water found within freshwater marshes.They build
their nests in the safety of dense reeds, using
the stems and leaves as nest materials.
Bitterns need wet reedbeds,so they can
catch fish without going into the
open.Bearded Tits feed on both
insects and seeds in the reeds.
REED WARBLER
Small patches of reed are perfect
for this songbird. Its strong feet
provide a good grip on upright
perches. It weaves its deep, cup-
shaped nest around several stems.
