Bubbles on surface of pond?
Evening all, Excuse the daft q but I noticed small bubbles rising to the surface of my pond today and I've not seen this before. Do you think it could be underwater amphibians causing them? I've not seen any frogs but I do hear plopping noises when I approach so I assume that's them diving in. The frogs seem to be very quiet at the moment though. Think I've given them too many hiding places as I hardly see them whereas last year I had 5 frogs at this time. The pond is over a yr old now and I'm still to see any newts in it but I keep hoping that one will take a fancy to the pond.
