Reduce electrocutions by using plastic, not aluminium, leg rings to mark birds
Overall effectiveness category Unlikely to be beneficial
Number of studies: 1
Background information and definitions
Leg rings, used to identify birds, could increase electrocution rates if made of metal. Therefore, plastic bands are sometimes recommended.
Supporting evidence from individual studies
A replicated, controlled study in Tucson, Arizona, USA (Dwyer & Mannan 2009), found that electrocution rates for 38 Harris’s hawks Parabuteo unicinctus marked with plastic leg bands were no lower than for 41 birds marked with aluminium bands. In addition, there were no signs of burning/electrocution close to the rings on dead birds’ legs.Study and other actions tested
