A warm September day at Hornsea

There were wide open sunny skies with a cold NW wind, but actually warm in sheltered spots at Kirkholme Point, the Eastermost area in Hornsea Mere. On arrival a group of wagtails by the water included a Yellow Wagtail. Around the point there were the usual assortment of Coots, Tufted Ducks, Canada and Greylag geese and Mute Swans. Three Grey Herons were dotted about the lake's shore, but despite scanning the viewable areas, no evidence of Great White Egrets, which I had hoped to see - although a distant Little Egret gave me first hope and then disappointment. It was a typical Sparrowhawk display day, with several individuals seen both displaying or being mobbed around the area.
  After a first slow walk around Kirkholme, we relocated to the church and Hall Garth Park. There were several stands of mature ivy in bloom, with its accompanying retinue of common wasps, droneflies and at some point a Hornet. Ladybirds were represented by at least seven 7 spot ladybirds, and many adult and larval harlequins

Dragonflies
Back on the mere in the afternoon, it was warmer and  invertebrates had become more evident. The highlight being odonates, with three species present, Common Blue Damselfly (2 males), Common Darter (1 male) and at least 5 Migrant Hawkers, which included watching a complete mating sequence.
