Hi clarelewlew
That sounds really brilliant – all that wildlife in your garden. You are so lucky having newts.
What you heard may have been the hedgehog ‘courtship’ where the male circles the female and she turns round and round within that circle huffing all the while. This can go on for hours and doesn’t always come to anything, but a good sign that you have a male and female there, so fingers crossed for some hoglets later on.
Good luck with the camera – hope you get some good images. Happy hog watching.
