Red Squirrel Activity is recorded by counting the number of times the lid of the Squirrel Feeder has been lifted by a Red Squirrel, or other animal (eg. pesky jackdaws) and recording it using a datalogger. There is a radio data link between the feeder and the datalogger.
The Squirrel Feeder consists of a cedarwood box with a hinged lid and a transparent plastic front, and is kept filled with nuts. There is a small platform in front for the squirrels to stand on. This arrangement is more-or-less 'Bird Proof'. The squirrels lift the lid with their heads and reach inside to retrieve the food. An actuator connects the lid to a microswitch that closes an electrical contact when the lid is raised.
