North Cave Wetlands – 29/09/2018

A sunny morning visit to the reserve with a gentle south-westerly breeze, temperatures reaching 12 degrees C.

Still four species of Dragonflies to be found mainly around Carp Lake. Brown Hawker Aeshna grandis and Common Blue Damselfly Enallagma cyathigerum now almost certainly eking out their final few days of the year. Plenty of Common Darter Sympetrum striolatum and Migrant Hawker Aeshna mixta obvious around the reserve.

Bird-wise the best bird of the day was the Black-tailed Godwit Limosa limosa which showed really well on Island lake. A Marsh Harrier Circus aeruginosus flew north over Reedbed Lake flushing a selection of Wildfowl onto Island Lake. The drake Mandarin Duck Aix galericulata was present on Carp Lake, where a Grey Wagtail Motacilla cinerea also put in a brief appearance. On Main Lake a Kingfisher Alcedo atthis was fishing from the dead trees on the west bank, whilst a Pink-footed Goose Anser brachyrhynchus was in with the “Greylags”. Several skeins of “Pinks” also passed over the reserve during the morning. A Curlew Numenius arquata was in the field near the entrance to the reserve, whilst a Red Kite Milvus milvus was over the ridge to the east.
