After a few months of things being very quiet, I saw a bit of action today. One of the peregrines flew in from the north and hovered slightly before landing on the central blind window. Shortly afterwards, the other came in and dived at the perched bird, both then tumbling around each other in the air, squawking loudly. They they flew for a while around over nearby buildings, chasing each other, before disappearing from view. I definitely saw a male and female, but it all happened too quickly to see who started it – could be the beginning of courtship behaviour…
