Résumé :	Few information about morphometrics and body mass of Woodcock (Scolopax rusticola) are available, all of them obtained from individuals hunted. During five winter seasons (from 1992 to 1997) 421 Woodcock-individuals (39% adults, 22.8% early juveniles, 38% late juveniles), were caught, ringed, measured and their weight taken in a wintering area of Central Italy. Morphometric measures and weight were analysed concerning age class, year, and month of capture. Recoveries are also reported. Juveniles had shorter tails and wing compared to adults but bill length did not differ. Birds weighted more in December and January. The birds seem to belong to the northeast Europe population and the recovery of several individuals in subsequent winters suggests a winter site fidelity.
