March 12th – I felt awful. Really bad, as if I had the mother and father of hangovers. I’d not had alcohol, and it could have been an MSG thing, but I was dehydrated and groggy. But I had to go out.

I called in at Shire Oak Park to check the frog pools to see if they’d mated there yet – if caught at the right time, that place is like toad soup but today, it was devoid of amphibia – but a heathy patch of spawn in each attested to the frog’s presence at some point.

I was interested in the difference in the frogspawn. I know that frogs produce globular ‘clumps’, and toads ribbons, but the frogspawn seemed to vary from the huge ones in my hand to tiny eggs the size of a small blackcurrant. I wonder why that is? Age and health of the female? Different types of frog?

Never noticed the variety in this stuff before.
