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.

March 11th – I wasn’t feeling well. An unpleasantly off-colour feeling had been descending over me for a few weeks. I ached. I felt dizzy. Something wasn’t right.

I grabbed a takeaway on the way home and shot from Clayhanger to Brownhills over the Spot Path and common – where, despite my fun, I found the migrating amphibians – out in huge numbers enjoying the drizzle – charming and fascinating. I love frogs and toads.

I took care where I was riding, and noted creatures of all sizes and hues. Very one of them obeying the same seasonal imperative.

Nature has a way of pulling you up short.
