Night recording etc

Following initiations with Dave Lambert (cheers Dave) and Paul Morton (cheers Paul) I've started doing some night sound trawling- which is basically leaving the sound equipment recording through the night and then checking the sonograms/spectrograms for distinctive signatures. So far my efforts are a bit crude/ basic but I've got some basic spectrograms here with some results from last night- a Little Owl , Redwings flying over and also a mystery bird. The images show the visual representation of the calls.


Met up with a couple of local environmental campaigners today, Sav and Rav from Thornton Heath to discuss some campaigning ideas and then I had a quick look round the farmlands for any migrants. Despite the good conditions (light rain and overcast) we couldn't find any summer migrants.

Up to 8 Water Pipits on the enclosed beds 

Flocks of Snipes were unusually flying around- groups totally 30-40. Appeared to be restless migrants. 

Skylark singing on the mound- great to hear. 

A couple of new moths in the trap last night- Common Plume and Twin-spot Quaker (below)
