Next-Router-State-Tree explorer

Soft-navigate between the routes below. The panel on the right intercepts every RSC fetch and decodes the Next-Router-State-Tree the browser attaches. Hard-load any URL — no fetch happens, so nothing is captured.

Spotted Nicobar Pigeon

Caloenas maculata

IUCN status
Extinct (known from one specimen)
Mass
unknown

Described from a single 18th-century specimen of uncertain origin. Likely a distinct island species lost before formal study.

The next outbound RSC fetch will encode [slug] as ["slug", "spotted", "d"] in the state tree the browser sends. Click a different species and watch the right-hand panel: only that array's middle element changes between captures; the static parents stay put.
