Advice on locating nest sites

Monday, February 14th, 2011

London has its fair share of tall buildings but few of them make suitable places for Peregrine Falcons to nest. If you’re considering installing a nest box it is important to assess the viability of the site in terms of the odds of the young fledging successfully.

One significant difference between cliff sites and urban sites is that many buildings do not offer fledgling Peregrines somewhere to perch if they are unable to make it back to the nest ledge. With nothing to perch on the birds will slide down the sheer face of the building or fly to other buildings nearby, desperately trying to find a perch. In this situation fledglings can quickly find themselves on the ground where they are extremely vulnerable.

Therefore only buildings with ledges or other niches where fledglings can perch make suitable locations for nest boxes.

Potential nest sites should also be assessed in terms of security and proximity to existing Peregrine territories. Please get in touch if you’d like more advice on this process.
