The dark art of sonogram analysis

This year we have been collecting data for the Pinpoint Bat Project. This has involved introduction to sonograms earlier in the year and a number of people have been very involved since in analysing files.

Last night we met to do a more advancxd course, which concentrated on how to get through hundred and even thousands of files, without being totally overwhelmed.

Bob outlined his methods which focussed on not agonising endlesssly and accepting that sometimes you coudn’t hope to identify to species  level( those pesky Myosis.).

After this brief introduction, folk got down to workng through their sounds files, helpng each other and gathering round when some-one had an unusual call. People were s  engrossed that they had to be reminded there were biscuits.

NB Biscuits

sonogram analysis is tiring!

Conclusions included insects were a pain and that social calls were many, various. and largely inpenetrable.

The evening ended with the technologically minded members of the group talkng about doing a QGIS course. This went over the heads of mere mortals but would mean that keenies coud producee their own maps.

The evening finished on a high. On leaving our room in Parkaide Hall, Andy, who is moth recorder for the county, found a  rare moth on the light switch in the hallway
