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 />
