Can frogs cycle a pond?

[Gemma]

My pond under construction is empty and doesn't have a liner yet but frogs are already allover it, so I was thinking is it possible to cycle a pond with just frogs and visiting birds?

Yes.
Any body of water will eventually form a biofilm that will process decomposing organic matter.
The biofilm population will adjust accordingly.

Thank you @MitchM That means I can fill the pond once is done and run it without adding fish till next Spring

I filled mine and ran it until the next year before adding fish. The main reason was our ph I had to balance it up after killing off the first fish I put in.

It sat empty of fish, but had plants, frogs, etc over winter. In the spring, ph was fine, added fish and boom a running pond!

Thanks @addy1 It's been raining every day here and my new pond is still without a liner, I first thought I'd be ok moving the fish this late in the year, but now i'm reconsidering. It's nice to know someone else who ran the pond empty and achieved a good result
