When the alerts in my local WhatsApp groups started to ping yesterday morning with reports of Willow warbler sightings in my area, I had a good idea where I might find one, along the trail beside the River Ely. I’d actually walked that way a couple of times in the previous week, knowing the first arrival must be close. And, when I got there yesterday, bingo! This little beauty, having made the long journey from sub-Saharan Africa, was flitting through the trees, searching for insects, singing all the while. I never cease to be amazed by the wonders of Spring migration.
