Rookery Counts

Now is the best time to get out and count your local rookeries.

Records submitted to the website are gratefully received; they all help to better understand the status of Rooks in the county. Submit records HERE and please include an active nest count and a six digit grid reference.

Go to 2021 Herts Rookery Map to see a map of known Herts rookeries including location, grid reference and number of nest recorded last year. The more that get counted this year the better!

Rookeries can range from just a handful of nests to many tens, can be found in both rural and urban areas*, and do move around. So as well as doing a 2022 count of a known rookery, can find a new Herts rookery to add to our database? 

*sometimes in seemingly unlikely places such as 'Roundabout by Tesco!'

A look back at Herts Bird Club website data for 2021

Now that we have closed our website to submissions from last year, what can we learn from the records submitted the Herts Bird Club in 2021? 

Herts Bird Club Committee member and Data Analyst Graham Knight takes a first look at the data.

Please download Herts Bird Club Website Data 2021 to read Graham's article which includes several interesting graphics to illustrate when and where our records come from and most recorded species.

Thank you again to everyone who has submitted records and please keep them coming in 2022. And remember that Grid Reference!
