They say hearing a cuckoo is one of the signs that heralds the arrival of spring. The urban setting of my daily ride isn't the type of environment conducive to supporting cuckoos, but then it also probably wouldn't be the kind of place you'd expect to see oystercatchers. Nonetheless, today, arriving at Greenbank, I was greeted by the screeching of three of them flying around the area. Last year, they were here in June. It must be a sign.
