And we've detected in the past things like otters, we presume, startling things.

And what is it that triggers it?

And the reason I ask you is because when I put the nest box up first and when I had the cameras in, I noticed that the birds were coming in on Good Friday every year.

You hear all sorts of... Sedge warblers and stuff.

Sedge warblers.

You might hear a moorhen suddenly cackle because it's been spooked by something.

We hear waders migrating in very memorably.

Yeah.

In recent times, we had a curlew flying over.

Every year.

Now, Easter changes every year, but the birds came in on Good Friday every year.

We had all sorts of birds like that.

And with light pollution, you will hear birds sometimes, particularly wrens and robins, that will sing even during the night.

And cuckoos will too sometimes.

Yeah, so no corn crickets in Cuscony Marsh, but elsewhere in the country there will be.

And obviously we're hoping the people around the country will let us hear their own recordings.

Can you believe it's next Saturday, Sunday morning?

That's what it is.

Do you know, just recently for the last few weeks, there's been an American bittern in Cuskinny Marsh.

I did know that.
