Four swifts screeching and scything through the blue sky over the back gardens of West Hampstead. They’ve come back exactly to the day (see post last year (https://petecoles.me/2013/06/04/theyre-back/). And it was on a 15 May that Ted Hughes published his poem “Swifts”. Curious precision. And at least there are still four of them, as numbers had been decreasing each year.
