White storks over the Polish wetlands

Backyard birding journal — September 2026

Poland holds the largest breeding population of white storks (Ciconia ciconia) in the world — roughly a fifth of the global total nests here, concentrated in the river valleys and wet meadows of Podlasie and the Biebrza basin. By early September most pairs have already fledged their young, and the storks are gathering in loose pre-migration flocks before the long haul to sub-Saharan Africa.

Identification

A large, unmistakable bird — pure white body, glossy black flight feathers, long red legs, and a long straight red bill. In flight the neck is held fully extended, distinguishing it at a distance from herons, which fly with the neck folded back.

Nesting behaviour

Storks build enormous stick nests on rooftops, chimneys, and purpose-built platforms atop utility poles — a single nest, reused and added to year after year, can weigh several hundred kilograms. Villages across eastern Poland actively encourage nesting storks as a mark of good fortune, and many towns keep a running count of occupied nests each spring.

Best times to visit

Few birds are as woven into a country's folklore as the stork is here — a genuinely good reason to keep looking up.
