Peter Jones, "Hampshire Diary"

Tuesday, June 12, 2007 - Woodcock, and more bat files

 Went for a walk mid-evening to the edge of the village. Stonechats and Whitethroat breeding in the field of waste ground, which is now virtually head height with grass! At least two Roe Deer were making their way through the grass virtually undetected. Also watched a Buzzard drop from the top of a pylon onto some prey, which it looked like he caught. Too far away to identify what he caught. A Kesrel also scored, as I watched him disappear into private woods with a small mammal in his talons.

Hung around the small heath / bracken area until 30 mins after dusk and saw plenty of Woodcock overhead. Looks like there is a healthy resident population right on the edge of the village, and with a bit of luck could probably add one to my Garden list (albeit pushing the boundaries slightly!).

Also, the area damaged by fire a couple of months ago is now completely regrown.

Some more local bat echolocation: 

Serotine:

 very irregular beats. Sounds like a bad jazz drummer!

Power spectrum below peaks at high 20's (Approx 28KHz, when x10)

 

Pipistrelle:

 Much faster beats, two species in neighbourhood: Common and Soprano.
