Woodcock (Scolopax rusticola) Science Article 1
abstract
The French breeding Woodcock population has been monitored since 1988, and since 1991, the monitored geographical area has been representative of that population. Monitoring is based on observing roding males, the methodology being random sampling with replacement. The annual results are expressed as a frequency of occurrence. The data collected since 1988 allow us to define very precisely the breeding distribution area of the French Woodcock population. The collected data have shown that the French breeding Woodcock population has been stable from 1991 to 2000.
