Breeding conditions:

| The 2007 spring breeding population of Wrangel Island Snow Geese numbered 140,000 birds (the second highest on record since 1970), an increase over the 130,000 to 135,000 birds counted in the previous year. Due to heavy winter snowfall that persisted into late May breeding conditions in 2007 were less favourable than those of the previous two years. The main colony had approximately 35,000 nests (down from 48,000 in the previous year), with mean clutch size 4.0 eggs and nest success of 85%, which is above the long-term average. This represents an unprecedented run of 10 consecutive good breeding years on Wrangel Island.
