2026-05-12 Vienna - Chicks 6 & 7 Fledge Seconds Apart from Nest Box 1

Описание: The fledging sequence accelerates in Nest Box 1 as great tit chicks 6 and 7 leave the nest within moments of each other.

With the box already much emptier than before, both chicks appear highly alert and eager to follow their siblings. After brief hesitation at the entrance, they quickly launch into the rainy and windy world outside.

By now, the instinct to leave has clearly spread through the brood — a rapid chain reaction often seen during the final stage of fledging.

A fascinating glimpse into the momentum and urgency of departure day.
