Greater Scaup visited the North Basin in rafts of several hundred in mid-December. But they didn’t stay very long. After just two days, their numbers dwindled to a handful. The mass of them flew off to parts unknown.
This morning, a sizable raft in excess of a hundred birds cruised just north of the park. They appeared to have no specific aim. Sometimes they moved in a coordinated V shape, then broke up into smaller groups, and then reformed in a shapeless raft farther from shore.
Their numbers so far show a steep drop from last year, when Scaup at times covered the whole North Basin from shore to shore.
