A day of lots of work and two Swift sightings. The first of the latter was about 4pm, a single bird, flying past the office window on the top floor of the tower block facing Paisley Museum. It called quietly, did a couple of wide circuits, and then drifted off over the town centre. The second was this evening, just before 10pm, one or two (I couldn't pick them out) screaming high above the centre of Cardonald. Both sites have had regular Swifts in the past, but in the last few years, sightings (or soundings) have become much fewer.
At least there are some Swifts about. I haven't seen or heard a House Martin in Cardonald for a month. Either they are feeding outside the area or they have decided that the cool, damp summer we have been having is not worth staying around for.
