Swifts have returned from the south
The first swifts have returned today. For me, their high-pitched sounds are the music of the summer. I love to hear them. I also love to watch the birds. During hot days, they rise up to high altitudes, following their insect prey. Now, the evening is still cool and a jacket is needed but I am looking forward to those mild summer evenings when the swifts come down and whirr around the house at high speed with their typical cries.
They are now going to stay until around the beginning of September, when they will disappear as suddenly as they have come, flying back to their African winter quarters. These birds are the real inhabitants of the air. It is believed that outside the breeding season, they can stay in the air nonstop for several months.
