Lowton Bird Observatory, Day 60


Lots of bat activity last night, apparently four species recorded over the garden, with common pipistrelle recorded 22 times, soprano pipistrelle twice, noctule four times and this bat which Echo meter keeps calling Nathusius' pipistrelle recorded once. I'm getting this species suggested pretty consistently now, but I'm a bit doubtful given the bats frequency (khz). It's always around 42khz but I thought Nathusius' pip wasn't meant to go over 40khz. Echo meter seems pretty convinced and there is a cluster of records from the Liverpool / Manchester, but I don't think I'll truly believe it until I get one under 40khz.
