20th May 2010: Metal-ringed Swift preening on the wing at Rathscanlan, Tobercurry this evening (top), and the two Swift nestlings that were ringed at this site on the 20th July 2009 (bottom)
Swifts eat, drink, mate, and even sleep in flight, only landing to incubate eggs and rear young. As the top photo shows, they also preen in flight. This bird is clearly ringed on the right leg (which it has brought forward). The outer primary feather is extremely worn (just the shaft left at the feather tip, often assumed to be a juvenile feature), suggesting this may in fact be one of two Swift nestlings ringed at this site last year. Swifts are not supposed to return to the breeding colony in their second calendar year, so this is highly speculative of course.
If you have a suitable building for Swifts (tall building, with suitable nest sites and clear flight lines), think about establishing your own colony. Remember this building is less than 5m high - many houses, apartment blocks,. and industrial buildings would suit.
