  Ampullariidae - Wikipedia, the free encyclopedia
Apple snails are exceptionally well adapted to tropical regions characterized by periods of drought alternating with periods of high rainfall.

Because the snail kite feeds almost exclusively on the apple snail (Pomacea paludosa), it is an example of an extreme prey specialist, and would, therefore, be expected to be at high risk from environmental variations that affect apple snail dynamics.
Apple snails occur in areas of extended inundation and their availability to kites is greatly reduced during droughts.
Radio telemetry (282 birds) and mark-resighting of banded snail kites (913 birds) are being used to estimate survival, to evaluate the influences of environmental conditions (for example, hydrology) on survival, and to evaluate the movement patterns of snail kites in Florida, including what environmental conditions are correlated with these movements.
