> 2 banded BFSs bave problems to recognize for the time being in Taiwan.
> One is recognized as T05 or A01. The other one may be A09, A12, T13, or
> T16.
>
> My conclusion as below:
>
> 1. BFS with green and red rings on left leg is T05 for sure. Please
> look at T05saved1999.jpg and T05noMetalring.jpg. This bird is rescued by
> Mr. Huang, local people at Chi-Ku, and me, Leo, in 1999. It doesn't have a
> metal ring on right leg. Therefore, it won't be A01, because A01 has a
> metal ring on right leg in Simba's previous excel file.
>
> 2. White rings sometimes become yellow rings on pictures. We have many
> pictures proved this pheonmenon. BFS with red-yellow rings or with
> red-white rings, the 3rd photo of attached files, could be A09, A12, T13, or
> T16.
> According to the 5-year report of marked BFSs by Collin Chen, BFSA
> director, T13 and T16 keep their company and visit Taiwan every year. T16
> still has numbered ring. T13 has lost its numnered ring last year. Collin

> Because we haven't recorded any information of A09 or A12 for
