So there we were, careening along the country roads, when daughter says,
"Ooo, what was that?"
Dad: "What was what? I didn't see anything."
Ruth: "There was a small bird at the side of the road. It flew up into a bush as we passed."
Dad: "Nope, sorry, missed that. What did it look like?"
Ruth: "Red at the front with a black head."
Dad: "Sure it wasn't a Chaffinch?"
Ruth: "Not a Chaffinch. Brighter than that."
Dad: "Probably a Robin with a hat on, then."
Ruth: "Yeah, it did look a bit like that."
Dad, with dawning realisation: "You've just seen a male Redstart!"
Dad: "I. Have. Never. Seen. A. Male. Redstart."
On arriving home, we went straight to the ID book. It wasn't a Chaffinch or a Robin with a hat on, or a Stonechat, it was a Redstart. A male one.
