Brown Argus – 30th April

This morning there were three Common Terns displaying over the Deep Pit and a teneral Common Blue Damselfly was found at the back of the Large Gravel Pit. Four Green Hairstreaks and two Dingy Skippers were seen on the Butterfly Bank. PS.

In the afternoon a Brown Argus was also seen on the Butterfly Bank. RW.

Avocet – 30th April

Early on this morning an Avocet and a Whimbrel were on the Slurry Lagoon. The Whimbrel flew off to the NE and a little later the Avocet flew to the SE, possibly to Holme Pierrepont. There were three Common Terns over the Deep Pit and these were briefly joined by four more.   PS.

In the late afternoon a pair of Garganey were on the Slurry Lagoon.   JMD.

Black Tern – 30th April

This afternoon there were signs that some more migrants had arrived with four Lesser Whitethroats in song. There were still no Garden Warblers or Grasshopper Warblers but in the Deep Pit a Black Tern was hawking for insects. It had a very buoyant flight as it rose above the water, flying into the wind. When it spotted an insect it dived like a falcon, probably catching a St. Marks Fly. There was a Lesser Black-backed Gull on the Slurry Lagoon and two Shelduck, but no sign of any Teal. PS.
