I've been somewhat surprised to see a Red kite circling over residential St Albans recently. Just the other day I saw it near the hospital, and I have previously seen one over the Waitrose car park. I don't quite understand why they're circling high over residential areas, though perhaps they're after carrion or small birds in our gardens. If nothing else it's good evidence of their continued spread across the country.
Sadly I don't have a particularly good picture of a kite as I always seem to be travelling in a car when I spot them aloft. They also tend to be fairly high, and though large birds they are still just a speck in the view of my lens. The picture above was taken in the fields outside St Albans last May. The silhouette is unmistakable, along with the white patches under the wings and the grey head.
The website linked above is well worth a look by the way, with a particularly good introduction to Red kites. I didn't realise that they are so large (2m wingspan), yet so light (2-3 lbs).
