这几天是清明假期，很多朋友应该全出门观鸟了吧。这是个最好的季节，春迁的候鸟有的回来了，有的已经在路上了。不过，你知道有的候鸟并不会走完全程么？他们可能会在途中停留度夏，这又是什么原因呢？我们可以根据白鹤的迁徙行为得出一些有意思的结论。

The next Siberian crane with ablue-white-bluering on its right leg was ringed withtransmitteron August 4, 2021 in the Kholboo sar lake (48.20343N, 110.02328E) of the NR Khurkh Khuiten. Photo DSC1890. Do you have a photo showing the transmitter on its back?

In the case of the white-backed crane here, it is not clear whether the ring on the right leg isred-yellow-blue or red-yellow-black. It looks like red-yellow-blue. If the lowest ring is blue, there is a ringed and transmitter-equipped bird in Duut Lake, Khurkh Khuytniy BNG (48.3361N, 110.377239E) on June 13, 2022. (Photo IMG20220613_151514)
