Grey Heron: Please count and report colony size now

The breeding period of grey herons is already in full swing. It is now and especially during April (but still before the leaves shoot!) the best time to find colonies and count the number of occupied nests.

The Swiss Ornithological Institute uses observations reported via ornitho.ch to document the development of the grey heron (see index). But your reports can also be helpful for other research institutes: a team from Eawag, in collaboration with the Swiss Ornithological Institute, has been searching for tags that have been used to mark brown trout under grey heron colonies in Central Switzerland. With the help of these data they can show that brown trout raised in fish farms (and later released into the rivers) are more frequently captured by grey herons than trout hatched and raised in the wild. So scientists are using your observations in their research which ultimately also serves to protect birds and other animals.

We are grateful if you try to count the number of occupied nests in known colonies and report this through ornitho.ch. We are also dependent on you to detect any new colonies: Grey herons flying into the edge of a forest can be a promising indication. In order make your data most valuable to science, please report colonies as accurately as possible (precise location) and fill in the number of occupied nests in the colony tool.

Thank you very much for your collaboration!
