Long Wood, Betws Bledrws

Whilst stumbling about in the undergrowth on a fungi foray this morning I heard a Willow Tit ( Marsh Tit being the more usual here), as well as a couple of Crossbills. On a different subject, my wife was shown a photo of a shark washed up on the beach at Aberystwyth the other day. About 1m long, it looked like a Blue Shark as far as I could tell. Not sure if this is unusual at all?
