Guarding frog spawn?

I know that some species of male frogs guard their frog spawn but I didn't think common frogs did this, however, I'm starting to think that is just what is happening in our pond. Martyn has posted photos of the frogs sitting in the frog spawn on his blog here

At least three frogs are still there today - they are male as they are croaking!

The spawn also seems to have so far escaped the fish. 
As I approached the spawn for a closer look, one large frog was sitting on it and then these two swam up, climbed on the the spawn and gave me a hard stare. They obviously see me as a threat maybe they remember that I stole some spawn earlier and don't realise that I did this to help!
They are feisty little things to try and intimidate something so much bigger than they are. 

When the fish approach from the other direction they definitely seem to turn toward them for a face off!

Has anyone else observed this type of guarding behaviour in our native common frog?

Another wildlife update
We bought a new wired nest box cam this year which Martyn finished setting up on Friday - Saturday morning a blue tit was already checking it out. If you haven't already visited his blog he has posted a photo of the prospective tenant here and a bit of video here

Epetition
I hope you've noticed the link above this post to the epetition calling for the government to review the fact that the Air Ambulance have to pay fuel duty even though it is totally funded by charity donations.. I've signed up!

  1. Hehe I had the same experience last week... One frog came then about six or seven popped up to give me the froggy stare. They were croaking at me very loudly

  2. I have never seen frogs hang around after the spawn has been laid...maybe it's a new defence they are trying??

    You just reminded me to get my bird boxes up quick!!

  3. How wonderful although I suspect they think they fish are a greater threat than you are.

    Thanks for helping spread the word about the Air Ambulance campaign. They're up to 80,000 signatures as of 8.00am Monday morning. Yay!

    1. I don't think they exactly trust me either BW - The tadpole celss are beginning to divide now.

      I wonder whether the government will honour the 100,000 signature promise with this one?

  4. Thats fascinating about the males guarding the spawn. I do find it interesting the different gender roles within the natural world. Male emus are like your frogs - they sit on the eggs and then bring up the chicks.

    1. A bit like penguins then Liz - not that we have any near to us :) They keep the eggs on their feet to protect them from the ice
