Pair of nesting urban peregrines: Natural Behaviour

On 17th February Terry Pickford recovered a dead female peregrine falcon (one of a pair) from this nesting site located on a church in Lancashire. What is very significant it was established the dead falcon had been dead since the 8th January at least. Between the 8th January and 17th February the male peregrine had shown no inclination to locate or replace his dead mate. However, once the body of the shot peregrine had been removed from a rain gutter on the building where the pair of peregrines had bred successfully last year, within 5 days the male had returned to the territory with a new adult female.

At first the unrung female played fast a loose, not showing much interest in the nesting box or the male falcon. In the weeks that followed the replacement female peregrine would fly off leaving the male alone for two days at time before returning back to the tower where the nest box is located. Things began to change towards the end of March when the first copulation was recorded. In early April regular food passes between the pair were recorded providing the first indication that breeding was likely.

We have now added several video clips together showing the pair doing what comes naturally over several weeks. Earlier this week the female was seen entering the nest box. We are confident she is now incubating a clutch of eggs.

What a remarkable climax for a breeding pair of peregrines which were brought together following a tragedy.

    Credit where it is due. You guys have done a great service in removing the dead female and subsequently, the male stuck around and nature sure took its course.
    Great story guys and well done.

    Well done to all concerned in this.

    I am sure everyone hopes for a successful outcome in six weeks time. Keep us posted.
