Long-term reproductive performance in white-fronted geese Anser a albifrons and tundra bean geese A-fabalis rossicus wintering in Zeeland (The Netherlands)
The reproductive performance of White-fronted Geese and Tundra Bean Geese was surveyed during 1964/65 to 1994/95 in southern Zeeland (the Netherlands). The proportion of first-year birds was higher on average in the White-front than in the Tundra Bean Goose (29 +/- 10% and 25 +/- 5%) and mean brood-...
