Breeding conditions:
|
| For the third consecutive year, breeding conditions were unfavourable for Greater Snow Geese on Bylot Island. In 2001, snow cover was the heaviest recorded since studies began in 1989. The timing of nesting was near normal. However, both nesting effort and mean clutch size were below average. Nest success was also below average (52%), due mainly to predation by Arctic foxes and avian predators which was relatively high despite an abundance of lemmings. The reduced reproductive effort and high predation pressure are expected to result in below average production of young (but much higher than the record low of 1999). Nonetheless, due to the high population level, a large fall flight is expected.
