Delayed hatching and subsequent infanticide by urban-nesting Peregrine Falcons

In association with the London Peregrine Partnership, I have been monitoring a Peregrine Falcon Falco peregrinus nest site on the Civic Centre in Morden, Surrey, since the nest was established in 2015. The nest is covered by a webcam operated by Merton Council. The 2023 season saw a changeover in the occupying pair. Both male and female of the new pair were in full adult plumage, so at least two years old, although they appeared inexperienced, particularly the male, who was very keen on courtship displays and little else. The female’s behaviour also suggested she was inexperienced, as is outlined below.
