Nesting Pairs and Chicks Raised (2006-2017)
Here are the breeding results we have recorded in bar chart format.
Over the last 12 years the average number of breeding pairs has been about 17 and the number of chicks raised has been 59.
In 2017 the number of surviving chicks was much higher than average. Even allowing for the fact there were more breeding pairs their success rate was above average. This would indicate that there was a big increase in vole population and therefore there was a plentiful food supply.
