Fastest bird in the world nests on top of an old clinker silo

Fastest bird in the world nests on top of an old clinker silo

 8th May 2012: Despite demolition work taking place in the area, a pair of peregrine falcons, the fastest birds in the world, decided that the top of an old clinker silo at a CEMEX UK plant in the Midlands was going to be ‘home’ for them and their future chicks.

In March, unaware of the peregrines’ presence, contractors decided to measure up the nearby stacker reclaimer for a new external staircase. The falcons protected their nearby home by dive bombing the contractors. The work ceased on the reclaimer and surrounding area to protect them and employees on the site are eagerly awaiting sitings of the chicks.

The majority of peregrine falcons stay within 100 km of their birthplace and for the last 4 or 5 years this CEMEX site has seen at least one pair of falcons nesting on the buildings. They require extensive open terrain for hunting and areas such as quarry faces and cliff ledges for nesting. Ledges on tall buildings and construction mean they are occasionally seen in cities.

Peregrine numbers declined during the 19th and 20th century due to persecution and today they are still under threat from illegal killing and nest disturbance. The banning of selected pesticides in 1982 has resulted in the slow recovery in the numbers with a widespread presence throughout the UK.

CEMEX UK, building materials supplier, and the Royal Society for the Protection of Birds (RSPB) are working in partnership to maintain, enhance and restore the biodiversity of the company’s land holdings. With practical advice on the appropriate management of the land in and around the quarry the partnership will help ensure the future of rare species such as Peregrine Falcons.
