The River Ogmore from Source to Mouth

Our second day in the south of wales included a class field trip to the local River Ogmore. There was little time to check for the local bird life however I did see 1 pair of Ravens near the source of the river and 2 Meadow Pipits.  During the course of the day, as we traveled downstream, I came across increasing numbers of Ravens with occasional groups of up to 10-12 Ravens circling the valley at 2 points on the trip and occasional Buzzards.  The farmland around our accommodation (the Margam Country Park Centre) also attracted a small group of 3-4 Ravens.  It seems the commonest bird that I came across on the entire trip were Ravens which also seem to equally common as Carrion Crows in England.
