Breeding conditions:
|
| Brant nest density varied among 5 Yukon Delta colonies, from approximately 50% of the average level (Kokechik) to slightly above average (Kigigak and Tutakoke). Emperor goose nest densities increased in 2002. The 2002 spring estimates of total Tundra Swans, breeding pairs, and nests on the Yukon Delta were all at record high levels (since estimation started in 1985). Ideal weather during nesting, low levels of fox predation, and the lack of flooding contributed to good production.
