This morning there were ten species of warbler, singing on the reserve. Two Grasshopper Warblers were reeling near the northern pylon. A Wood Sandpiper was on the flashes beside the Ouse Dyke and a Pied Flycatcher was reported near the Wader Scrape bench. PS.
This evening there were seven Wheatears in the ploughed field by the sub-station. A Grasshopper Warbler was reeling half way along the Causeway and a Green Sandpiper was on the flash across the river. JMD.
This morning a superb adult male Marsh Harrier flew through, over the Slurry Lagoon, towards the NE. Lots more warblers were in, including two Garden Warblers, and a male Wheatear was on the Wader Scrape. PS.
This morning a Wood Warbler was found on the railway embankment beside the signal box. Also seen were a Hobby and a Cuckoo. RW.
In between showers this afternoon some corvids were soaring in the sky, trying to mob a Buzzard. As I watched a large swift-like bird came into view as a Hobby circled over the site. As I followed the Hobby three Swifts came into view beyond it. They were probably catching St Mark’s Flies which were flying in good numbers at the time.
This afternoon there were twelve Common Terns on the tern rafts. A flock of around fifty Swifts drifted high over the reserve and a Hobby alarmed the Swallows by the railway bridge, other raptors were two Buzzards, two Kestrels and two Sparrowhawks. There were several butterflies about, including Brimstone and Orange Tip and a Stoat was running up the Deep Pit bank, following a trail, its tail held high. PS.
