Peter Jones, "Hampshire Diary"

• Sunday, June 10, 2007 - Evening on Downs, and Barbastelle

Saturday early evening on the downs, near Broughton.

Yellowhammers, Corn Bunting and a Few Lapwings, plus Linnets, and Whitethroats.

Later, at dusk, headed to a small pond near the "Mottisfont Bats" SSSI. Was lucky enough to pick out a Barbastelle amongst the many Natterers and Daubentons Bats feeding over the water.

Natterers were whizzing inches from my face, which was fine, but a Tawny Owl that glided silently past me within a couple of metres got my heart racing!

Very brief sound file of the Barbastelle attached:

And sound analysis: 

Which shows the peak power at approx 35KHz (need to multiply the graph by 10 for true reading).
