Nesting Pairs and Chicks Raised (2006-2021)
Here are the breeding results we have recorded in bar chart format.
Over the last 16 years the number of breeding pairs, although very variable, has slowly risen and in 2021 reached a new peak of 41.
In 2021 the number of surviving chicks was also much higher than average. Even allowing for the fact there were more breeding pairs the success rate was above average. This would indicate that there was a plentiful food supply and favourable weather conditions. In 2020 and 2021 the breeding population may also have benefitted from reduced human interference due to the various COVID-1 9 restrictions. Another important factor, we feel, is our continual programme of maintenance of existing sites. Most of our work involves both repair of boxes and the barn roofs that protect those situated within farm buildings.
