Media notes
Only processing is applying a 300Hz High Pass Filter and then normalizing to -3db in Audacity. The same bird at the other recording. There is a high level of background noise from a nearby road that can be minimized with a more aggressive High Pass Filter.
Observation details
A lifer for me. Easily identified by it's vocalization. Photos and audio captured and included. Looking at the photos now at home it is easier to see visual field marks. The short bill all yellow-orange underneath is notable. Different than resident Hammond's and Dusky with dark tips. It's eye-ring separates it from Willow. It's primary extensions to me look "not short" but "not long". Underneath it is relatively pale colored without much, if any yellow. Separating it from Cordilleran. One interesting plumage observation are the greater coverts. The inner 4 look fresh with wide light tan tips. The outer 4(?) have essentially no light colored tip left. Kaufman's Field Guide to advanced birding mentions the Least undergo a partial molt before spring migration that involved a "variable" number of coverts. This observation could be indicative of that. The inner coverts with broad tips being fresh and the outer with no tips being old. I did not research if this is species specific.
