This has been great, it helped me ID an Osprey, I was where I didn't think they'd be.
Its ID'd a Peregrine Falcon twice, I've still not seen it.
It does list Red Kites as Common Buzzards, I am not sure how to provide feedback to update this.
I tend to use Merlin, and Seek as I walk around Essex. Seek doesn't seem to know about Sessile Oaks.
