Source-derived summary

Foca Island (Spanish: Isla Foca) is an island in the Pacific Ocean located in the northern Peruvian region of Piura. The island is within the area of convergence of the Humboldt Current and the Equatorial Current, with the presence of marine species of both temperate and cold waters due to that phenomenon.

Editorial summary

Begin with the source’s own compact description: “Foca Island (Peru)” is island in Peru. The dossier treats that line as a proposition to test through Foca, Island and Peru, not as a finished interpretation.

Editorial reviewA valuable geographic starting point for tracing changing names, boundaries, uses and administrative responsibility. The current 52-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. For this dossier, Foca, Island and Peru is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “island in Peru” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Jul 14, 2026. The linked authority identifier is Q5921621. Authority coordinates are -5.210, -81.206. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

Critical limits

A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Treat names, boundaries and functions as historically changeable. Maps, plans, inventories and administrative records can clarify what the place meant at different dates.
