Heligoland Traps Named after the island on which these traps were first designed and used, the Heligoland Trap is basically a large funnel made of netting and ending with a collecting box where birds are finally caught and removed. In order to catch the birds it is necessary to actively move the birds into the catching end of the trap but for the rest of the time birds are free to come and go at will. The major advantage of this type of trap is that they can be used in any weather conditions.
