A Whinchat and a Wheatear were seen this morning, both on the Deep Pit fence by the Railway Bridge, though not at the same time. Two Hobbies were also seen here. About six Brown Argus were seen around the site and more Long-winged Coneheads, as well as several Migrant Hawkers, Brown Hawkers and a Southern Hawker. The Lower Path had a flock of warblers, containing Garden Warbler, Blackcap, Whitethroat and Lesser Whitethroat, Willow Warbler and Chiffchaff, plus two Willow Tits.
Whilst looking for the Roesel’s Bush Cricket we stumbled across a population of 5 males and 1 female, including a copulating pair, of Long-winged Coneheads. We also found the Roesel’s Bush Cricket nearby.
The stridulation was much higher pitched from the Coneheads. Some members of our party could hear neither cricket, whilst some could only hear the Roesel’s, due to the frequency ranges involved. Younger people tend to hear them more easily than older people.
The Roesel’s was found in E2 whilst the Coneheads were found in E2 and D2 (at the top of the steps).
