Short-billed Dowitcher Limnodromus griseus

An extremely rare vagrant to Europe with just one accepted record from the UK. I still find the identification of adult Dowitchers very difficult and I am not 100% certain about the identity of the birds shown below. Please do get in touch if you think I am right, and especially if you think I am wrong!

probable Short-billed Dowitcher, Bacon Street, San Diego (California, USA), 19th April 2005 - I believe this is a Short-billed Dowitcher due to the breast sides appearing more spotted than barred, however I am not 100% certain. Some of the scapulars and wing-coverts appear to show the pattern typical of Short-billed, with the white tips extending up the sides of the feather merging into the orange sides, but others are less convincing (to me at least). The loral angle is perhaps a little shallow suggesting Long-billed and the black tail bars are rather wide (although these are variable on both species). It was in estuarine habitat which favours Short-billed, but migrants can turn up anywhere. Comments welcome.

Short-billed Dowitcher, Ding Darling, Sanibel Island (Florida, USA), 16th April 2013 - again this one's ID isn't clear-cut for me as some features - at least the way I'm reading them - point in opposing directions. On balance I'm leaning strongly towards Short-billed, but let me know what you think

Short-billed Dowitcher, Ding Darling, Sanibel Island (Florida, USA), 16th April 2013 - this very summery bird seemed to have spotted sides of the breast (not barred) but was too distant to photograph well. A Short-billed this red would have to be hendersoni I presume?

presumed first-summer Short-billed Dowitcher, Boca Chica (Florida, USA), 19th April 2013 - even harder in this plumage and I'm by no means sure about this ID
