Przebieg lęgów wsiedlonych kuropatw pochodzących z hodowli – badania radiotelemetryczne

The aim of the study was to collect information about the course and results of breeding of hand−reared grey partridges. In the years 1997 and 2000−2001, 15 released females were radiotagged in the second half of April and observed to the end of July in western Poland. A half of the hand−reared females died within first several days. No clear differences in the course of nesting between hand−reared and wild partridges were observed, both in the case of clutch sizes and nest locations, as well as in incubation start dates. However, none of the observed hand−reared females achieved breeding success because of their high mortality as well as clutch and chick losses. The main cause of losses during breeding season were carnivores.
