Bird, watching

When I was in the back garden, the sky was ridiculously blue and the birds in the tree were ludicrously loud. An incredible amount of them too. 

Every now and then they'd all take off at once. The tree would fall silent for a while until the volume of the mad chirruping built up again. 

I was whistling absent-mindedly to myself, and noticed a few of the birds flying down to where I was. I couldn't help thinking they'd come to check out the twittering human.
