Description
  • We investigated antiparasitic tactics in ground nesting Common Pochard females towards intraspecific brood parasitism. The behaviour of the tested females towards the experimental dummy was compared with their responses towards the stuffed female Ring-necked used as a control. The reactions towards both dummies were similar: Pochard females typically swam silently around their nests and observed the dummy. The lack of differences between the measured parameters recorded in the experiments with conspecific and pheasant dummies may indicate that female Pochards do not recognize the conspecific intruder as a specific threat. In addition, the responses of the incubating female towards the conspecific female on her nest were studied using continuous video recordings. The data indicate that active sophisticated anti-parasitic tactics have not evolved in Pochards, although there is some level of defence towards intruding conspecific parasites.
