Key messages

A single, replicated study in Finland found that hand-reared grey partridges Perdix perdix did not take off to fly as effectively as wild-caught birds, potentially making them more vulnerable to predation from ground predators.

 

About key messages

Key messages provide a descriptive index to studies we have found that test this intervention.

Studies are not directly comparable or of equal value. When making decisions based on this evidence, you should consider factors such as study size, study design, reported metrics and relevance of the study to your situation, rather than simply counting the number of studies that support a particular interpretation.

Supporting evidence from individual studies

  1. A replicated ex situ study in 1993 and 1994 in Finland (Putaala et al. 1997) found that hand-reared grey partridges Perdix perdix took flight with a shallower take off angle (average of 31o tested on 12 birds) and climbed more slowly (climbing rate of 1.8 m/s for 11 birds) than wild-caught birds (average 44o for 19 birds tested and 2.7 m/s for 18 birds), potentially making them more vulnerable to predation from ground predators.
