Went out looking for invertebrates with the team in the afternoon during a patch of sun. Slowly walking the long loop at Killeröd produced some nice stuff and a few birds too. BK has experienced an influx of firecrests this spring and so it was no surprise that I finally found one of my own today when a male started singing right next to me. I have spent so many days in previous springs listening near suitable stands of spruce without success so this bird was very well-received. There are perhaps three or four males singing in BK at the moment! Other birds included a few cuckoos and some singing tree pipits (an overdue year-tick!).
