Why does vitamin D come from two totally different things; oily fish and sunshine?
It made me wonder if all our current scientific theories are wrong? Maybe mackerel are not fish after all, but silvery blue packages of pure sunlight? Or the sun emits rays of fish oil instead of photons?
What a poser! The world is all wrong!
Anyway, at Langford I was able to concentrate on the birds, and ignore such existential meanderings. THe dominant birds were the sand martins in the air, of which there were many, and various loudly squabbling canada geese on the water. But there was plenty else going on.
A tiny little gravel island out on the water was the focal point for most of the activity. On this little spit, barely larger than a decent sized car, oystercatcher, common terns, and various ducks including a very late pochard were all sitting or feeding in the shallows. Possibly the terns and the 'catchers were nesting; I hope so.
I decided to walk around the whole reed bed, and everywhere a shrill song caught my ear. I've been researching birdsong like mad, and have concluded it was almost certainly a sedge warbler; certainly it is an ideal habitat for them. A passing birdwatcher told me of a hobby he had watched, but it didn't show up for me. Lots of butterflies were about, and I'm glad that orange tips are having a good year again, after last spring's disaster.
Brimstone flew strongly around the hedgerow margins, and peacocks sunbathed out on the paths in large numbers. No damselflies yet though, although they've been reported elsewhere.
