10pm, just arrived back from my NCT test (it was a late one) and as I was banging the hub caps back onto my car wheels, I heard Redwings flying above my head in the night sky - first time I've ever heard their night migration flight call.
Very cool sound.
If you're out at night and hear some birds making a very high pitched noise above your head, its more than likely Redwings as they make their migration from Scandinavia or Iceland into Ireland for the winter.
