There is an assumption that the equinox always falls on the 21st but it can actually be as early as the 20th and as late as the 22nd! Anyway, this year its the 20th and after that we start to get a fraction more daytime than nighttime until the summer solstice.
Sad to have missed our rare sea duck today but I was doing the Marsh tomorrow anyway so it just means that I am ahead of myself about that too!

Having said this to Yvonne (who I know is far more computer adept than I) was obviously a proverbial 'red rag to a bull' as within a day she had identified an excellent scientific paper on the species which I have attached for anyone interested here: https://www.ncbi.nlm.nih.gov/
The actual title falls of the tongue, being; "Phenotypic Divergence among West European Populations of Reed Bunting Emberiza schoeniclus: The Effects of Migratory and Foraging Behaviours". See, its scientists playing the 'join my club if you want to understand' card - if they called it 'everything you need to know about why Reed Buntings look different and why they go where they go' a lot more people would probably have read it!
Anyway - respect to the Yvonster, a well found article that requires a couple of reads to get the feel of but which is worth the effort.
That'll do for now - have a grand equinox everyone - Chaz
