Aberystwyth swallows

To add to today's other reports, there was one swallow happily sitting on the roadside wires near Coleg Ceredigion this morning on my way to work. Passing at 4pm it was still there but now joined by a second, and on my way home at 6.30pm, a flock of six feeding nearby! Does that make it officially Summer? Great news about 'Monty' the osprey Emyr - let's hope the female isn't far behind...
