St Davids area update

The Purple Heron was picked up in flight along the road near Ivor's Pond at 8:30ish, it dropped into a rough area near a willow clump, ignoring a nearby pond. After about half an hour it came up again, landed on the bank of the pond before flying around and eventually dropping into an area of rough ground and gardens at Treleddyd Fawr. Again it ignored the nearby farm reservoir, as well as Ivor's Pond itself. It is an adult in breeding best and looked stunning in the sunlight, both in flight and on the deck (down to 25 metres). I hung around till 10 am and I believe John and Marion arrived soon after but it hasn't been seen till now. It didn't seem to want to go far though. I continued to Whitesands where there was a female Black Redstart along The Cabin Track down to Whitesands Beach (I think the fifth of the spring), a couple of Redpolls went over and there were 3 Wheatears and 3 Pied Wagtails around the Car Park. There were about a dozen of both Willow Warblers and Chiffchaffs at the Head along with 3 Blackcaps, a Song Thrush and a Sand Martin. A Hooded Crow put in a brief appearance at the Burial Chamber. To finish, a female Harrier sp appeared, looking slim bodied, long and slim winged (no real secondaries bulge and not terribly accipiter like) with 4 primaries prominent as it circled higher and higher. It had dark secondaries and coverts giving a strong contrast to the pale outer wing. I couldn't make out much of a head pattern but it became high very quickly. Don't know. No Coal Tits today, unfortunately, because I was hoping to check out my suspicion that yesterday's birds were continental rather than British. Not a bad day really.
