North Cave Wetlands – 25/09/2018

A sunny morning visit with a cool gentle south-westerly breeze, temperatures around 12 degrees C.

Four species of Dragonflies still present, a male Brown Hawker Aeshna grandis still hanging on being the highlight around Carp Lake. Also still a few Common Blue Damselfly Enallagma cyathigerum present around the reserve. Only a couple of weeks left now for these two species. On the other hand, Common Darter Sympetrum striolatum and Migrant Hawker Aeshna mixta were obvious around the site, these two species will still be around for another month or so.

A good day for Shieldbugs, with two Blue Shieldbug Zicrona caerulea seen along the northern path, where several Spiked Shieldbug Picromerus bidens were also noted. A late instar Hairy Shieldbug olycoris baccarum nymph was a nice find, with and adult also found along Dryham Lane. A Corizus hyoscyami was in the Car Park area, the third of the year, worth looking our for this recent arrival to the area. Finally Common Froghopper Philaenus spumarius and Field Damsel Bug Nabis ferus complete this list.

On the Birding front a Marsh Harrier Circus aeruginosus caused a bit of a commotion on Island Lake, flushing a Dunlin Calidris alpina which circled around the lake several times before heading of in the direction of Main Lake. Great Spotted Woodpecker Dendrocopos major and Green Woodpecker Picus viridis were in the Maize Field area and hedgerow. Two skeins of Pink-footed Goose Anser brachyrhynchus headed north low over the reserve containing 62 and 14 birds respectively. The highlight however fell to the male Stonechat Saxicola rubicola found on the northern path near the large Rosebay Willowherb patch. The drake Mandarin Duck Aix galericulata was back on Carp Lake where a single Chiffchaff Phylloscopus collybita was also present. Finally two Kingfisher Alcedo atthis flew east past South Hide.
