Towards the back of the tidal marsh where ground elevation increases is a fringe of mangrove trees. These provide cover and nesting sites for the birds and mammals who use the lower marsh as a feeding ground.
Eagles fly by flapping huge wings, but that consumes energy.
They are able to conserve energy and fly long distances by riding air currents. The eagle has 10 primary feathers attached to its wing. They adjust these feathers individually to maneuver. The fiddler crab plays an important role as prey for many creatures. When disturbed, they run for their burrows, which can be identified by the marble sized pellets of mud that they pile up at the entrance after excavating.
