in Gloucester, MA·counted·75 all time
An oystercatcher, a shorebird with long legs and a distinctive bright, straight bill.
Counted, not streamed: Oystercatcher 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.
