Nathusius the next chapter

What could be even more exciting than 2 Nathusius pipistrelles?

Last night we caught our sirt bat in our new herp trap.
We set up four harp traps and acoustic lure as part of the Nathusius Pipistrelle Project. There was an ecstatic reaction  when this beast fell into our harp trapLeisler wriggling

She was not best pleased to be caught and wriggled a ot – as this photo shows.

But we forgave her everything but she was a Leisler’s bat. This is the first time we have ever caught a Leisler’s in the county. We have thought that we have heard Leisler’s in the past, but they are very difficult to distinguish them from Noctule if you listen to the sonograms
Once she had settled down, Bob managed to get some better photos of herLeisler side view crop1

Nathusius Surveys

Last night we were joined by Daniel Hargreaves in order to harp trap near Biggleswade. Four harp traps and acoustic lures were set up and three of them caught bats.

Daniel returned from checking one trap bearing 3 bats with him.

You can see that the Nathusius is bigger and furrier than the other pipistrelle series.
This was the cause of much delight as it is only the second Nathusius ever caught in Bedfordshire.
Later that night a second Nathusius, also a male, was caught – much celebration followed. Both bats were ringed and a fur sample taken for DNA analysis
Since the  Bat Conservation Trust Nathusius Project began in April, Nathusius bats are being found all over the country. We have spend the last month looking hard, so it was great to catch one. Now we will be going back once a month to resample the site  (under the terms of the Nathusius project)
