Survival.

One wonders how any young birds have made it to fledgling stage for their parents have had to cope with just about the worse climatic conditions I can remember, but made it some have although with daily reports of greatly reduced numbers coupled with many complete failures.
Fair numbers of Swifts hawking the skys above Bampton looking like the aerodynamic wonders they are as they grace the eventide before I turn in for the night leaving me in awe of the lifestyle they have adapted to through the process of evolution and indeed if there is an unused niche in the natural world the evolutionary process will respond.
