Question:
We noticed that seagulls were flying in flocks northwards
while pelicans were flying south. Any significance for this
behavior? Where do these birds go during a storm? Where do they go
on a regular night?
Replies:
It sounds like what you've observed is local movement, not migration,
perhaps in response to food supplies, resting areas, or other local factors.
Most birds simply "sit out" storms wherever they happen to be, perhaps in
the same place as their night roosts. Gulls in the Midwest tend to flock at
night along large lakes - here in NE Illinois on Lake Michigan. Pelicans
here generally roost at night on larger inland lakes. I am not sure about
coastal behavior.
