Not by me, but others have now recorded the first Chiffchaffs, Sand Martins and Swallows of the year, and one of my circle even had a Wheatear in the Brecks last weekend.
But not me. So, instead, I will tell you some more about the Chiffchaff. It's scientific name is Phylloscopus collybita. The first part, from two Greek words, means "leaf gleaner". The second part, collybita, also from the Greek, means "moneychanger", from the supposed resemblance of its chiff chaff chiff chaff song to the sound of coins clinking together.
Not many people in Huntingdon know that.
