Monitoring of the breeding population of Rooks

The spring is here... As a result Rooks are already present in their breeding colonies and eager to build or repair their nests!

The correct way to submit sightings about Rook colonies:
In order to monitor Rook colonies and report them correctly, please follow the instructions in the "Rook monitoring" section (here, in German). These instructions will help you to determine when and how to report colonies and how to properly use the “colony breeder tool” from ornitho.ch for this species.

Many thanks for your commitment!
