his prey consisting of night insects and moths. This is a hiding bird, his presence is mostly revealed by his night cry. The ground nestling wood warbler (Phylloscopus sibilatrix) likes pri marly the broad-leaved forests. The food of our carnivore bird living in the undisturbed forest parts - the goshawk {Accipiter gentilis), is very various. Birds, mammals, sometimes insects and fish are in the menu. The lesser grey shrike {Lantus minor) set a part of his prey (which consists mostly of insects) on thorns or spiked twigs and consume it later. He is a migrating bird arriving at the beghining of May and leaving at the end of August. The bird which is smaller than the wren or the wood-warbler, the goldcrest (Regulus regulus) visits our region during the autumn and the whiter. On of the well-known birds of the arid steppe is the skylark {Alauda arvensis). The stone curlew {Burhinus oedicnemus) is a big, squat bird wit big, yellow eyes. He feeds mostly insects but captures smaller mammals, frogs, lizards too. He spends the winter in North Africa. The collared pratincole {Glareola pratincola) nests often with other species together hi large numbers. The crane {Grus grus) is bigger bird than the stork. In the last century the Crane brood hi the country, today we see only the autunmal and vernal migration of groups of tens of thousands birds in Hortobágy. They are very vigilant birds, having sentries during feeding and sleeping. For the night they settle on the shallow water of the fishponds. In summer we can meet few imperial eagles {Aquila heliacd) at Hortobágy. The red-footed falco {Falco vespertinus) and the kestrel {Falco tinnunculus) nests often together with rooks hi small forests compassed round with land hi tillage or hi forest-belt along the roads, and looks for their preys sitting on high objects, on powerlines, or hovering hi the air and captures them after with a quick plungehig. Many species are attached to the biotopes of humid steppe such as the lesser white-fronted goose {Anser erythropus), the white-fronted goose {Anser albifrons), the garganey {Anas querquedula)

, the redshank {Trigna totanus), the ruff {Philomachus pugnax). At many places the lapwing {Vanellus vanellus) is called libuc, liboc.
