Up close, swifts are pretty ordinary, brown birds with under-developed legs that enable them to hold on only briefly to walls and landing places. But in flight they are supreme, capable of feats of aerobatics, deadly at intercepting insects, even sleeping on the wing (which it achieves by sleeping with half of its brain at a time). It is estimated that swifts fly an average daily total of 800 km --- nearly 500 miles. That's about 2 million km in a lifetime.

So, if you have a moment to stop, look up and welcome back the PGS swifts.
If you are interested and want to help the RSPB, they are currently conducting a national swift survey: http://www. rspb.org.uk/applications/swiftsurvey/
