Caught in the Act!
There were two clumps of frogspawn in the pond this morning
and when I glanced out of the kitchen window mid-morning it was obvious that there was lots of frog action in the pond. I put the 70-300mm lens on the camera and managed to get some pictures. I didn't bother with the tripod partly because I was worried that the frogs might disappear if I went back into the house but mainly because I had to clamber over the rockery behind the pond to get the sun behind me and its a bit of a precarious position to mess around with the tripod!
Here you can see a male and female frog in an "amplexus" embrace. When the females return to the pond a male may get in this position and remain there for days or weeks until spawning begins. As far as I am aware no-one knows what exactly triggers the spawning. The female lays eggs and fertilization by the male takes place externally. He has to shed sperm as soon as the eggs are laid as the spawn rapidly swells in water and within a few minutes the eggs are no longer accessible to sperm.
You can see from the photo how swollen the female's belly is with eggs.
I could count up to 7 frogs in the pond and here's some more photos of the frogs and "action".
There was plenty of croaking to be heard too. Just have to hope now that there won't be any hard frosts and temperatures below freezing that could damage the frogspawn.
Finally, one of the stock doves has been feeding each day in the garden and I managed to get a photo at long last through the kitchen window.
