Habitat preferences<br />

The Saker falcon is a typical steppe species,<br />

preferr<strong>in</strong>g open landscapes, and <strong>in</strong> Europe <strong>in</strong>habits<br />

wooded steppes, agricultural areas and mounta<strong>in</strong><br />

foothills [11] . The species specialises <strong>in</strong> hunt<strong>in</strong>g small<br />

to medium sized diurnal rodents, Suslik (Spermophilus<br />

citellus) <strong>in</strong> particular, but will also take birds,<br />

such as Starl<strong>in</strong>gs (Sturnus vulgaris) and Domestic<br />

pigeons (Columba livia forma domestica) [9] .<br />

Like other falcon species, Saker fuses nests<br />

constructed by other species, such as Eastern<br />

imperial eagle (Aquila heliaca), White-tailed eagle<br />

(Haliaeetus albicilla), Raven (Corvus corax) and<br />

Common buzzard (Buteo buteo) [4, 12] . Nests are<br />

traditionally <strong>in</strong> tall trees and on cliffs, but recently<br />

the species began us<strong>in</strong>g electricity pylons and<br />

currently the majority of pairs <strong>in</strong> Central and<br />

Eastern Europe nest on pylons [8, 9] .<br />

Legal protection and conservation status<br />

The Saker falcon is listed <strong>in</strong> Appendix II of CITES,<br />

Annex I of the EU Birds Directive, Annex II of the<br />

Bern Convention and Annex II of the Convention<br />

on Migratory Species [13] .<br />

Although reliable data are not available before<br />

the 1980s [8] , it was evident that the Saker falcon<br />

experienced significant decl<strong>in</strong>es across its range<br />

<strong>in</strong> Europe s<strong>in</strong>ce the mid-1900s [5, 9, 15, 26–29] . The key<br />

populations <strong>in</strong> Hungary and Ukra<strong>in</strong>e, for example,<br />

were estimated at just 30 and 30–40 pairs, respectively,<br />

by 1980 [8, 28, 30–32] . Accord<strong>in</strong>g to the most recent<br />

estimates of population size (Table 2), the European<br />

population of Saker falcon numbers approximately<br />

740 pairs and appears to be <strong>in</strong>creas<strong>in</strong>g.<br />

The population <strong>in</strong> the Carpathian Bas<strong>in</strong>, which<br />

makes up more than 40% of the total population<br />

<strong>in</strong> Europe, has been recover<strong>in</strong>g s<strong>in</strong>ce the 1980s,<br />

ma<strong>in</strong>ly driven by large <strong>in</strong>creases <strong>in</strong> Hungary and<br />

Slovakia [30, 33, 34] , but also <strong>in</strong> Austria where the species<br />
