A chickadee is a small songbird, typically recognized by its black cap and bib, pale cheeks, and gray back.
Counted, not streamed: Chickadee has no time series, so it is read as a footprint across places. All-time count by city.
Things that physically exist: street furniture, signs, buildings. All-time counts.
