Abstract:
The hoopoe (Upupa epops) is a rare insectivorous, ground foraging bird inhabitating open and semi-open landscapes. One of Austria’s largest populations of this species, which shows a declining population trend throughout its range, occurs in Lower Austrian wine regions Wagram, Kamptal and Kremstal. These birds breed and forage within or close to vineyards. Visual observation during the foraging flights and mixed effects logistic regression models were used to assess hoopoe response to vegetation structure and vineyard farming practices. The aim was to detect driving factors for foraging habitat selection and determine management practices favouring the hoopoe. The results showed that visited and randomly selected vineyards had a similar vegetation height and percentage of bare ground in the alleys between the vine rows. However the probability of hoopoe occurrence significantly increased in vineyards with heterogeneous vegetation structure underneath the vine rows characterised by a high amount of bare ground interrupted by patches of vegetation. Furthermore management practices within the vineyards seem to have impact on hoopoe appearance. Interestingly, herbicide application underneath the vine rows seemed to create heterogeneous amount of bare ground promoting vegetation patchiness favoured by hoopoes. Furthermore, the number of cuts of the vegetation in the alleys and soil loosening had significant positive effects on the occurrence probability of the hoopoe. The area underneath the vine rows seemed to be of central importance for foraging hoopoes in the vineyards. Although the vegetation model showed no significant influence of vegetation height or amount of bare ground in the alleys, still regular cutting of vegetation showed a positive effect. The remove of vegetation underneath the vine rows together with regular cuttings and loosening of the alleys seemed to offer suitable conditions for hoopoes foraging within the vineyards of Wagram and Kamptal.
