观察细节
Singing male warbler with a rather short tail and longish slightly decurved bill. Black and white above with white streaks on black mantle, white wing bars and tertial edges, white below with black streaks concentrated on upper breast and merging into partially black throat, bold white supercillium and malar framing black auriculars, additional eye-arc beneath the eye. Short streaks on undertail coverts. Creeping on branches like a nuthatch and singing distinctive very high and squeaky up-down-up-down song (squeaky wheel), which was how I first detected and identified it. Diagnostic photos and recordings obtained but probably can’t post before Monday night. Ponderosa/Aspen stand at NW corner of office, behind main information kiosk, and once flying to elms/Russian olives due west. Stopped singing around 9 AM and couldn’t relocate but presumably still around. Do not venture into restricted areas.
