On 12th September 2015, the HKBWS Bird Ringing Team captured an Oriental Reed Warbler at Mai Po Nature Reserve. It’s not a surprise to record Oriental Reed Warbler at this time of the year, but it is interesting that this juvenile bird was ringed in Japan!
The code of the ring on this Oriental Reed Warbler reads “KANKYOSHO TOKYO, JAPAN 3F95886”. Members of the ringing team immediately contacted Yamashina Institute for Ornithology of Japan for information. The institute replied that the bird was ringed on 5th September 2015 at the river mouth of Tenryu River, Iwata, Sizuoka Prefecture, Japan. As the ringing site in Japan was approximately 2,700km from Mai Po Nature Reserve, it was believed that this bird had spent at most 7 days to fly all the way here, which means it flew at least 385km per day!
Every ring recovery of a bird helps us to understand more about migratory birds as well as their migratory pattern. We would like to encourage you all to pay more attention to ringed birds and share with us by e-mail at firstname.lastname@example.org photo of their birds (preferably with ring number, if possible).
