Following the color flagging of Bridled Terns (Onychoprion anaethetus) in 2017 (https://eaaflyway.net/bridled-te ... inged-in-hong-kong/), the Agriculture, Fisheries and Conservation Department (AFCD) of the Hong Kong Government continued the flagging of terns in Hong Kong. The three species of breeding terns in Hong Kong, i.e. Bridled Tern, Black-naped Tern (Sterna sumatrana) and Roseate Tern (Sterna dougallii), were flagged in July 2018. The flagged terns have white flag on right tibia and engraved yellow flag on right tarsus (see photo). A total of 58 terns were ringed (among these 43 were flagged) in 2018. It is aimed to find out more information on the migration route and wintering sites of these terns. Researchers and bird watchers are encouraged to report any sightings of these birds to the AFCD (ivy_wy_so@afcd.gov.hk).
Remarks: The AFCD would also like to thank the Hong Kong Bird Watching Society for their technical support in the ringing activities. Author: HKBWS Tung Time: 19/06/2020 10:42 Subject: Terns with leg-flags 有腳旗的燕鷗
Dear members and birdwatchers,
We will still collect leg-flag re-sightings (i.e. date, place, flags colour and numerals on flags) of breeding terns in this summer as the study of breeding terns is still continuing. This information can help us understand more about the breeding terns in Hong Kong of their age, survival, and home range. All leg-flag sighting records are welcome and can be posted here.
