Hello Tom,
Thank you very much for your post. We are glad to hear that you enjoyed your visit to the reserve and that you saw a nice variety of birdlife.
We are sorry to hear that you didn't see the cranes. They are very much in and out at this time of year and do spend a lot of time feeding in arable fields out in the Fens. The best time to see them on the reserve tends to be February and March. They can be quite visible at that time of year so it may be worth making a visit if you are able to.
We hope to see you on the reserve again soon.
Many thanks,
David White
Visitor Experience Officer
