BIRD CONSERVATION ON BUILDINGS

Peregrine Falcon Nest Box

Accessory Mounting Rack

The Peregrine Falcon, an impressive globetrotter. This species of Bird

is found almost everywhere around the world: with the exception of a few

isolated areas, it breeds across almost the whole of Europe. The Peregrine

Falcon (lat. falco peregrinus) is capable of very fast flight, and is noted for

the speed which it attains when diving to catch its prey, which can reach

200 kph in short bursts. Like all Birds of Prey the female is much larger and

heavier than the male. In Europe this Bird almost became extinct due to

the effect all kinds of chemicals in the environment, poaching, the spread

of sporting activities and many other factors. Stricter nature conservation measures have aided recovery but it still

remains at risk. The breeding habits of these Birds in Europe are both unusual and fascinating. For example, in

Central and Southern Europe they are found exclusively on rock faces, cliffs and buildings, while they also breed in

trees in Eastern and Northeastern Europe.

How can we help? Peregrine Falcons are a popular sight in our towns and cities. Because their diet consists

almost entirely of Birds they help to keep the numbers of feral Pigeons in check, making them the most natural and

cheapest method of controlling the numbers of these Birds. Unfortunately, as a result of building renovation and/or

the construction of new buildings with their relatively smooth façades and roofs, it is becoming increasingly difficult

for Peregrines to find suitably sheltered spaces. The creation and installation of artificial nesting aids has proved

very useful in this respect. These boxes have been developed as a result of experiments carried out over many years,

and with the biological knowledge that has been gained about their breeding requirements. The main features are:

» the provision of a spacious, protected and securely attached breeding space for these Birds of Prey.

» a robust, long-lasting structure that requires little maintenance.

» PEREGRINE FALCON NEST BOX

The spacious interior offers the Birds plenty of room in which to create a

nesting site, and in particular the young have enough space to exercise

and develop their flight muscles. The built-in "balcony" makes it easier for

the Birds to leave and return to the box. A perch is also included, and this

is important because the young Birds are prone to falling out of the nest

site. Webcams can be installed inside the box for monitoring or observation

purposes.

Method of installation / suitable sites: E.g. in quarries or on high

buildings such as towers, silos, high rise buildings, highway bridges

(for example on or around the abutments).

Installation height: Generally in heights above 25 - 30 m. North- or eastfacing sites have proved to be most effective. The "balcony" with its perch

should be placed so that there is a clear area directly below. The box can be

attached directly to a building using screws (e.g. on flat roof sections) or, by

means of a mounting rack and wall plugs, onto an outside wall.

Recommended litter/ bedding: Place some gravel or other loose material

in the box. Peregrines do not construct nests, instead the female scrapes

a hollow in which to hatch the eggs. The breeding period starts any time

between mid-March and the beginning of April.

Material: Special, high-strength, reinforced lightweight concrete.

This ensures that the box is very long-lasting (decades) and allows a proper

and structurally correct manner of installation. The naturally grey, smooth

concrete can be painted individually during installation to match the

building, if required.

Dimensions / weight (empty nestbox):

External dimensions: D 130 cm x W 80 cm x H 73 cm.

Nesting chamber: D 72 x W 67 x H 54 cm.

Weight: approx. 260 kg (empty box).

Supplied with: box with integrated

drainage holes, removable inspection

flap, perch.

Order No. 00 305/8

» OPTIONAL ACCESSORY: MOUNTING RACK

Installing the box on walls. The fixings between the

box and the bracket are supplied. The attachment and

fixings between the bracket/wall must be arranged

in accordance with the particular site and obtained

separately. The bracket is provided with 6 holes on the

wall side.

Detailed layout and dimensions for planning of

installation are available on request.

Material: welded and zinc-plated steel construction.

Dimensions: Mounting rack with attached Nest Box

approx. H 180 x W 80 x D 135 cm.
