The data behind the plate

The same verified record the back print is drawn from — read the way the field guide reads it: where the heron lives across the year, how it measures against the rest of the guide, its annual cycle, and where it stands on the IUCN list. Ranges, not means.

Reading the grid. Cell shade is an ordinal bin (eBird bar-chart convention) on a perceptually-uniform sage→deep-green ramp; darker = more activity. Diagonal hatch = recorded absent; flat warm-gray with a ringed dot = no survey data. Present year-round with a spring breeding peak; eggs Mar–Jun (laying peak May); northern populations on passage in spring and fall.
