This is the current sight in my ponds!!
Yes, it's spawning time for the Frogs and later on there will be the Millions of tadpoles too, after they hatch from the Frogspawn.
I welcome the frogs as they are great to have in a garden, eating all the Insects & slugs which harm the young plants. In October the Frogs find a cosy place to hibernate over wintertime.
Usually in a compost heap or under bricks.
Then March they re-appear and head for the pond they were most likely born in.
No wonder I get so many returning.
