There are lots of swifts in Aix. They fly very close to our terrace in the evenings. We originally thought they were swallows, but then we realized they were martinet, or swifts.
It makes us think of watching the swifts on Ken and Jill's roof deck with a champagne cocktail (champagne with a bitters-soaked sugar cube -- try it, it's delicious, but it was Jill's recipe and I can't remember the name). Sigh.
Here's a video (quality isn't great because it's night and taken with our camera). You can see and hear how close they fly in toward the terrace.
They're pretty cool to watch because they fly really fast and very close to the windows on the street side of our apartment too. What I would love is to have a video of them flying up into the roof tiles. There's no stopping to land on the gutter and then stepping in, or even (apparently) slowing down. They just fly right in.
