Block Island
National Wildlife Refuge

A wing crosses the coast.

A black-crowned night-heron dominates the sky above a small lighthouse and curving shore. The refuge is read through a bird’s presence, not a panorama alone.

Reverse design anatomy

One bird,
three spatial layers

The Mint identifies a black-crowned night-heron above Cow Cove, looking toward Sandy Point, with North Light behind. Those place and species names come from the source, not guesswork from the raster.

The following close reading describes visible forms. It does not assign undocumented intentions to the artists.

USFWS describes Block Island as an important Atlantic migratory stopover, especially for songbirds. The refuge was established in 1973. This habitat context does not prove the migration route or behavior of the particular heron shown.

Area figures differ: the Mint records 133 acres and the current USFWS account gives 134. No single acreage is presented as settled here. The visual reading stays with the bird, shore and refuge function.
