Ornithological workshop in Sándorfalva
This year at the Ornithological workshop in Sándorfalva the main topic was the defensive opportunities against the nest-predators. This topic is quite actual for us on the Life project areas, since the indicator species for example the Black-tailed Godwit (Limosa limosa) Lapwing (Vanellus vanellus) the Avocet (Recurvirosta avosetta) nests on the ground, so these species are more dangered by the predators. The nesting colonies are really vulnerable. Only a few predator can be harmful for the nests, and can trouble birds while nesting. For this reason its important to get more knowledge about predator species and get familiar with the methods which help to monitor and control the number of the predators.
In our case predators can be divided to „feathery” predators and „furred” predators. On the project areas we can detect predators that are part of the natural fauna, and predators from the urban environment as well, such as dogs, cats, or brown rats. These animals can appear easily on the areas of livestock farms. The most important natural bird predators are the Hooded crow (Corvus corne cornix) and the Magpie ( Pica pica). The native predator mammals are the red fox (Vulpes vulpes) the badger (Meles meles) the boar (Sus crofa) and the polecat (Mustela eversmanii), besides these the number of the invasive predators is improving ,such as the golden jackal (Canis aureus) the racoon dog (Nyctereutes procyonoides). These predators are mostly harmful for the eggs, and the nestlings, they usually can’t catch the adult birds.
The professionals can use several methods to control the predators. The aim of the predator-control is to keep their population low, especially in the breeding period of the birds. The direct control method is the hunting and the trapping of the animals. The indirect method can be the proper landscape management, and drive back the optimal living areas of the predators.
