Sažetak
Field rodents, when too abundant, can cause considerable economic losses in perennial crops, especially lucerne. Predatory birds can provide a natural control of field rodent populations since the field rodents are their natural pray. However, the modern agricultural landscapes of forage enterprises usually provide few or no natural standpoints for predatory birds for ravening the pray on the ground. According to the old farmers of east Croatia, T-standpoints” installed into lucerne were traditional implements easing the bird predation over field rodents. Aim of this study was to check whether the T-standpoints really are an appropriate installations for predatory birds ravening the pray on the ground or not. Research comprised the installation of two T- standpoints at approximately 1 ha of lucerne crop in the village Ernestinovo in Croatia and monitoring of predatory birds landing to the installations, ravening the pray and landing to the ground during 10 months of observation. The research has confirmed that predatory birds (Buteo buteo and Falco tinnunculus) used the installed T-standpoints for ravening and occasional landing to the ground, probably for catching a pray. Approximately 13% of the lendings to the T-standpoints ended with a landing to the ground and some prey attack. During 2018, the highest attendance at the T- standpoints and the highest number of landings were during September and October, when there were expected the highest field rodents population densities within low plant cover on alfalfa. During 2019, an even higher attendance of T-standpoints was observed during March, April and June, but with a smaller average number of landings per observation day, probably due to a decrease in the rodent population following the loss of individuals during the winter. During May, there was a very low attendance and number of attacks per day of observation, probably due to very rainy weather.
