Broad-winged

A domestic form of either African or Eurasian collared-doves -- not a juv

Yes. On any shorebird you think might be a Sanderling, count the toes.

Why adult? Why not second-year, which is more likely, given the streaking below.

Green saddle with blue head and wings leaves only one option

1 -- Semi and Least; White-rumped 2 -- Semi, Sanderling, and Semi/Western 3 -- maybe

There are no such swallows: Tree Swallow — 14 cm Bank Swallow (the smallest ABA-Area swallow species) — 12 cm Vaux’s Swift — 11 cm Rufous Hummingbird — 9.5 cm

Ticks

There are ZERO juvenile shorebirds in spring, except for those early-breeding Killdeer.

Yellow’s tail spots are yellow. I blame this misunderstanding on the plethora of people that don’t seem to understand that not every word-ending “s” requires a prior apostrophe. The “Yellow’s” in my post was intended as a possessive, referring to the previous noun phrase “tail spots,” one of only two reasons in English to use an apostrophe (the other being to indicate “missing” letters in a contraction).

It was a joke.

Bang on

Herring

Yes. Broad-taileds have very plain faces, without BCHU's obvious eyeline. They always look somewhat surprised to me. Well, the ones without red gorgets, anyway.

Wood is larger and has more and obviously nearly circular BLACK spots below. The eye rings are white, not buffy. The upperparts are much redder.
