Newborough Forest on Anglesey served up a treat as we looked into one of the largest raven roosts in Europe as part of this year's Autumnwatch.

Just being at the roost is a pretty amazing experience but it's the sound that gets you. As the ravens come into the roost the noise just keeps building and building.

Phew! We're already halfway through this year's series of Autumnwatch and we've been busy criss-crossing the country solving some of nature's mysteries. From Dorset to Petworth then to Birmingham and now we've just landed on Anglesey where we'll be taking a look at Britain's largest raven roost.

To see the fallow deer at Petworth in the rutting season was magical. It was fascinating hearing the noises made by the bucks - their deep Barry White grunting sounds being a constant soundtrack to our visit!

With it raining so much this Autumn, it's been a good year for fungi - and there are loads around at the moment.

Fungi are really interesting to find and I'm always intrigued by the array of shapes and sizes they come in.

I recently found a whole lot of large fungi around a tree - which was pretty special.

To me, fungi seem to have an air of the fairytale about them and I half expect to see a fairy or pixie hanging about. Not very natural history, I know. (Don't worry I havn't been eating them!)

Things are hotting up here as we get ready for the new series of Autumnwatch - and I can't wait.

This year, presenter Simon King will be witnessing some truly amazing autumn spectacles and trying to unravel some great wildlife mysteries. Expect small ninja deer in surprising places and a gargantuan conger eel plus a few surprises in between.

In the mean time, I seem to have stumbled across a mystery of my own - which I'm hoping you might be able to help solve.

When I was a boy messing about on the River Taff (at the weir just near the Millennium Stadium) I remember distinctly finding a tiny eel, but at the time I wasn't sure what it was. It was in fact a juvenile eel called an 'elver'.

Some animals are just plain cute. So cute in fact that you just want to have one!

It's been an unusual week, to say the least. Saturday saw me on a rubbish dump waiting for seagulls to land. We were making a radio programme about seagulls that inhabit rubbish tips and were with some scientists who were using cannon netting in order to capture and ring them.

This week, I hated wildlife. I jumped up and down and shouted like a loon directly at an animal,,,, but in my defence, it had just stung me.

There has been an extraordinary amount of rainfall in parts of the country which has resulted in rivers bursting their banks and many places being flooded.

I woke up bleary-eyed the other day to be met with what seemed like hundreds of birds on my house. It was a scene straight out of the famous Hitchcock film - The Birds.

They were in fact a flock of house martins that must have contained 50 or more individuals.

This week I heard on the grapevine that otters had been voted Britain's favourite mammal, straight in at number one.

Rain, rain, rain, it's been non-stop. The rivers are in spate and are full to the brim, which is relatively unusual for the height of summer.
