Should add a big "Thank you" to the person who put it on Lincolnshire birders Facebook page originally. Without whom we wouldn't have known about it.

Nice to meet you this morning....(Graham n Chris who were there when you arrived.)

Yep, the track by the pond with the wooden platform and just past it overlooking the scrape where the egrets usually gang out.

I read this book cover to cover and found the level of information in it fantastic. Been brilliant allowing me to ID the various rodents in our local barn owls diet.
In addition, the photos of the pellets, teeth and skulls are very useful.
And I never knew so many birds produced pellets.
