Spatial movements of grey gartridge Perdix perdix: male-biased spring dispersal and effect of habitat quality

Original language description

The grey partridge Perdix perdix is a sedentary species with a surplus of males in spring populations. It experienced a dramatic decline in Europe primarily due to habitat loss that may have forced the species to modify its dispersal behaviour, a less transparent source of populations threats. We analysed the dispersal patterns of grey partridges during pre- and post-breeding periods in two landscapes with different habitat quality in the Czech Republic. Grey partridges tended to pair off quickly, withmost pre-breeding movements executed in pairs. The birds usually dispersed over a few hundred metres indicating that the habitat conditions in a landscape with a carrying capacity of 2-5 pairs/1 km2 was not below the threshold initiating strong dispersal, as observed in extreme habitats and at the northern limits of the species´ distribution range. A few single males that had remained unpaired until April also finally bred, but they biased the pre-breeding dispersal strongly in favour of
