Both yesterday and today the island has hosted the sudden appearance of literally millions of a tiny moth called a Diamond-back. They arrived with the NE winds apparently an uncommon wind direction for the island. Local Moth expert David Wedd says he has never seen a population explosion of this species here and that this species is African. This begs the question how on earth have they turned up on NE winds. The insect-eating passerines are certainly enjoying them !

A Hobby rocketed across the golf course this morning and the pair of Peregrine were again over Essex Castle hill. A single Shelduck was on Bray Beach.
