To Dowitcher experts,

A few days ago, this dowitcher was seen in the new wetlands at Magnuson
Park.

I am confused about its identity and look for your insights.
LBDO is usually thought to be the more common dowitcher encountered in
fresh water. But several features of this bird make me think SBDO:
- supercilium is fairly arched and loral angle seems large enough for a
short-billed (2nd figure)
- V formed by supercilia is tapered and not pointed as in long-billed (1st
and 3rd figures)
- spotting and not barring on flanks
- short (?) and slightly decurved bill
- margins of retained coverts have a v shape, rather than squared off

Thanks,
