147 Eurasian Skylark 雲雀
Long Valley 塱原

Assuming that you know this is a Skylark from the first photo, go to the second picture.
Note the three tertials marked by red pointers above the tail in the photo, and also the tip of the longest primary. Note that the tip of the longest primary is roughly 0.5 in (1.3 cm) longer than the tip of the longest tertial. This is a good field mark for Northern Skylark (effectively rule out Oriential Skylark).
