Spring????

The gov's under the weather, coughing and blocked up nodes so we have to go for a daily walk to clear the tubes.
I spotted this "buttercup" and she corrected me, saying it's a celandine. (we've played this game for over 40 years).
Whatever, what's it doing in flower at this time of year.
And was that a cuckoo or just a woodpigeon with hiccups I heard?
