It seems that Pittsburgh missed waterfowl migration this fall with only a handful of the expected migrants landing on our rivers and lakes. Except for long distance migrants, waterfowl haven’t come at all.
Some ducks, geese and gulls only move south when ice overtakes their location. If they’re hanging out at Lake Erie near Presque Isle, the map of yesterday’s water temperature indicates they have no reason to leave. The water there is more than 40°F and the only ice is in small bays (black color on the map).
There are a few rare geese, though, photographed and posted to eBird and embedded below.
There’s currently a Ross’s goose (Anser rossii) at North Park, noticeably small than the Canada geese it’s hanging out with.
Yesterday there was a brant (Branta bernicla) at Duck Hollow without any Canada geese to keep it company. So it hung out with ring-billed gulls.
And a flock of 16 greater white-fronted geese (Anser albifrons) who normally migrate west of the Mississippi and winter in Louisiana, southern Texas and Mexico have been hanging out with Canada geese in Butler County since 1 December.
These geese are called “white-fronted” because their foreheads are white.
Wondering why the ducks aren’t here? This 2021 vintage article explains why.
