I have been counting active Heron nests with Professor David Norman as part of the BTO Heronries Census at the same site since 2014. During a break from revision, it was great to get back to the site again...

2014 Survey
2019 Survey
In the last 5 years the numbers have not changed as much as we have!
2014 - 70
2015 - 64
2016 - 71
2017 - 69
2019 - 47
But as you can see, there is quite a noticeable dip in this years numbers. It is too early to say why, but it will be interesting to see the results of other counts this year, particularly in Cheshire.
For more information about the census, you can take a look at my blog from last year celebrating 90 years of the survey, or visit the BTO's website.
