Lesser noctule

The bats and the bat workers are all asleep.

I'm from County Meath I actually grew up in Slane and actually the bridge at Slane and going down along the river valley at Slane is fantastic for bats because you've got lovely old woodland you've got the river there with a bat detector in my hand usually I'd go down pretty early so the sun wouldn't have set yet Before the swifts have headed to bed, Leisler's bats will come out first.

So they'll come out and you might see them against the horizon and usually they'll head south.

And then as it gets darker, obviously you can see less and less, but that's when you'll be able to start detecting Daubenton's bats.
