On the fourth day...
You’re going to have to take my word for it: there genuinely are four birds in this tree, calling to visit our bird-feeder below. I think a blue and a great tit, a sparrow and I suspect the robin I’d just seen on the lawn, but I had to be jolly quick to get exactly four – no more, no less – so I didn’t have time for an extensive ID check.
