A hundred of Aleutian Terns were fitted with geolocator and metal rings on their legs for studying their migration by American researchers from their breeding grounds in Aleutian islands this summer. If you are lucky to see any tagged Aleutian Tern in Hong Kong, please make a report of it here or send me a PM, or email (bfspoonbill @hkbws.org.hk (delete the space)).
