Visible migration

Birds were on the move last Saturday at Tophill Low NR, East Yorkshire. Up to 4 Greenshanks Tringa nebularia moved south during the first part of the day, with a Green Sandpiper present on the river early-afternoon. After a rather large electrical storm late-afternoon, things picked up with 4 Green Sandpipers Tringa hypoleucos high south, 1 Greenshank high south, 3 Whimbrel Numenius phaeopus high south and a movement of Common Terns Sterna hirundo with 43 south between 6.55 and 7.05pm.

The overnight moth haul involved 70 species. A lower total of individuals than the previous week, but the highlights included a single Diamond-backed Moth Plutella xylostella and a Dingy Shears Enargia ypsillon.

Migrant Hawker Aeshna mixta a welcome addition to the year list, but as one of the late season species, an indication that the summer is beginning to conclude. Twelve Southern Hawker A. cyanea the first decent count of the summer, while 63 Black-tailed Skimmer Orthetrum cancellatum one of the highest site counts ever.
