Lesser Kestrel is strongly attached to agro-environmental landscapes, showing high preferences towards extensively managed wheat crops and extensively grazed or otherwise maintained pastures. The species is an essentially insectivorous, opportunist feeder, capable of exploiting a wide range of terrestrial and aerial prey.
Lesser Kestrels are often nesting in urban areas, as they provide nesting sites and reduced nest predation and are usually surrounded by agricultural fields or open uncultivated grasslands, securing food sources. The species is therefore highly dependent on human activity not only for foraging areas but also in terms of available nesting sites.
In the past, the Lesser Kestrel was widely spread in Bulgaria, nesting “everywhere” in the mid-19th century. At present, there are no Lesser Kestrel breeding pairs confirmed in Bulgaria.
