This morning a Cuckoo called briefly beside the Slurry Lagoon as a solitary Swift flew over. During the Warbler Walk, eight warbler species were heard and six Hobbies were seen hawking insects over the Large Gravel Pit. Around seven Hairy Dragonflies were seen, including two females egg-laying, one on the Slurry Lagoon and one on the Small Gravel Pit. Two female Green Hairstreaks were seen, also egg-laying. An Oystercatcher was on the Wader Scrape and a Little Ringed Plover was on the dry end of the Slurry Lagoon. PS.
