What happened

White storks: Why introducing non‑native species in rewilding projects can be a good idea Lisa Lock Scientific Editor Andrew Zinin Lead Editor White storks (Ciconia ciconia) are a majestic bird with a two-meter wingspan and an enormous circular nest.

Why it matters

The recent release of these stunning birds at multiple sites in England, with more releases planned and a public consultation under way has kicked off a debate about whether non-native birds should be part of rewilding projects.

Common ground

The government advising body Natural England says it does not consider white storks to be native birds.
