Estuary, the usual March WeBs numbers of birds.
Marshes;-
2 small parties, 4/5 Sand Martins appeared to fly straight through;
2 Greylags on the river, after a couple of flights the eventually took off again(c1100) & left towards Carms. where presumably they are from!
A female Goosander roosting with Mallard & Teal(c30), & Snipe(c15) still flying as the tide reached it's high point.
Chiff's singing in a few well spread out locations today.

Brimstone butterfly, 1 seen today, near the river watchpoint(Wendy & Dyfed) , & having gone home to check, once I told them how unusual / rare! they are in Pembs, they have confirmed their ID.... will be looked for tomorrow!!
