Last March 6th I posted as below. This latest post gives a little more detail
of the mic I used then, and more recently last Sunday evening whilst recording
bats. The mic takes its inspiration from Curt's parallel boundary work and
John's "tree ears". Many thanks to them for sharing.

Back in March we visited family in SW Germany. We flew by budget (very)
airline and restricted the luggage (for three persons) to three carry on bags
of 10kg each and one hold bag of 15kg. I also wanted to try and record
woodpeckers so light weight recording gear was mandatory. The LS-10 clearly
was on the list and I decided to complete a collapsible, barrier project.
The starting point was "Corrux" corrugated plastic sides held together by wire
frames that slide into the corrugations

The finished component parts including the earmuff windshields are shown here
(WM61As fitted)

and the assembled barrier is in this photo

On this photo the elastic bands for holding the ear muffs can be seen, as can
the high density foam padding which was added to prevent slippage when the
barriers are used as tree ears. The green velcro straps used for fastening the
barriers to trees can also be seen.
The next two shots show the deployment of the rig when making the buzzard
recording

I was about 40 metres into the wood trying to record the woodpeckers. I heard
the buzzards who were flying around the edge of the wood at about my level or
just below . I walked back to the wood edge where I could see out over the
valley

there were three buzzard hunting in the valley. The Radio Aporee aerial phot
shows the location a bit better. It was noisy as the B47 main road, the
touristy "Niebelungan Strasse", goes through small hamlets in the valley bottom
and main air routes pass overhead.
I was a little disappointed in the performance of the Panasonic WM61As. A
pair of Rapid triplets would have done better in this situation.
However the extended frequency capability of the Panasonic capsules proved very
useful in last Sunday's bat recording experiment - post to follow.
