Heronry Surveys

Last Tuesday Theo had a 'survey day' and in the morning he covered one of our Hen Harrier 10k squares for the national census. No birds were recorded in the area but it was not too surprising as most of the surrounding habitat was not very suitable for HH hunting or breeding efforts.

In the afternoon he visited a couple of active Heronry sites to record nest occupancy for the annual BTO census. He had counts of one and six 'apparently occupied nests' and will visit again in the weeks to come.



Did you know that this is the longest-running monitoring data set for any breeding bird in the world? This annual census started in 1928!
