In reply to dread-i:
> I've put up 3 nest boxes under the eves. I'm hoping for some to take up residence.
Good, they need to be encouraged.
> I remember as a kid them nesting under the eves of my parents house. I'm not sure if that was common, and we're seeing less of them now. Perhaps its just rose tinted memories and they nest in the same numbers, just in different places.
60% decline in breeding numbers in the UK since 1994. Source: https://www.bto.org/our-science/projects/breeding-bird-survey/latest-result... - select swift from the drop-down list to see the graph. RSPB says they're on the red list https://www.rspb.org.uk/birds-and-wildlife/wildlife-guides/bird-a-z/swift/ Basically, any help you can give them is more than welcome.
> I still cant tell the difference between a swift, swallow or martin, but admire their aerobatics all the same.
Swallow and house martin I can understand being tricky to distinguish*, but swifts really are very different: noticeably longer wings cf body length, classic crescent shape and quite stiff wingbeats in flight. They also don't tend to fly breathtakingly low over grassland like swallows and martins do, preferring to stay rather higher - although they will come lower over water.
The starlings round here seem to be very good at mimicking screaming swifts, which can be confusing!
* I spent a good ten minutes the other day try to convince myself that there were swallows (which would have been the first of the summer here) hawking for insects over a local field. Turned out both species were present, so I'd ID one confidently and then the next minute manage to convince myself I'd been mistaken because it had swapped places in the binos with one of the others. Sometimes birds can be rather uncooperative.
