Busy baby birds

A little wren built a nest in my greenhouse and I worried when I didn't see her for a while that maybe she'd underestimated the heat of her new home (a joke with our current weather!). Today however I was welcomed by the sound of her babies chirruping! Well actually it was more like a a series of tiny thumps as they panicked and flew into the windows!

No sign of any baby swallows as yet...
