• Green-veined White (Pieris napi); 2
• Whites (Pieris sp.); 3
• Peacock (Inachis io); 1
Mayfly - possibily Ephemera danica
• Damselfly, the Banded Demoiselle (Calopteryx splendens); 3
• Mayfly, sparse swarming by the river and a short distance from it. I think they were all Ephemera danica given the large size and brown wing markings.
Ragged Robin (Lychnis flos-cuculi)
• The notable plant in flower was Ragged Robin (Lychnis flos-cuculi). Seen in the ‘Rushy Meadow’ on the valley side.
A good range of both resident and migrant species seen or heard during the walk as is normal for this site. Two good breeding records obtained for the Tetrad:
• Reed Bunting (Emberiza schoeniclus); ♀ seen obviously feeding young down by the River Thame;
• Starling (Sturnus vulgaris); rowdy group of adults and fledged young feeding around the River. I suspect they were attracted by the swarming Mayflies.
Other birds of note were:
• Cormorant (Phalacrocorax carbo); 1
• Grey Heron (Ardea cinerea); 2
