Walking back from doing my posting for the day I decided to walk the small stretch of the Cynon between the "Cress" Bridge and Mountain Ash Bridge.
About half way up I noticed movement near the far bank and a quite small Mink swam downstream and then up onto some fallen branches and then onto the bank where it made its way into the overhanging brambles and bushes.
I walked up another 20 yards and noticed some other movement near a sewer again on the far bank. This time a Water Rail came into view. Only the second one I have seen on the Cynon in Mountain Ash. The last one was in the exact same place in 2006.
On Monday I saw 10 Goosander flying up the Cynon around 2.30 in the afternoon.
Unfortunately no camera with me on either occasion.
