As near as I can tell yesterday's low pressure area that moved eastward
along the northern Gulf coast was purely an interesting meteorological
event without a corresponding ornithological component. Southern Louisiana
to the Florida panhandle got a good soaking but with water, not birds (if
I'm wrong about this please please correct me; it is hard sometimes to pick
up on small scale movements of migrating birds when you are depending on
random posts on list servers). What bird movement I saw on NEXRAD through
the day seemed to be flocks of large-bodied birds such as herons and ibis
and perhaps Franklin's Gulls and late waterfowl like whistling-ducks and
Blue-winged Teal, not passerines.The wind map is fascinating but its value
in forecasting the movements of migrants remains to be seen although the
potential seems high. Today there seems to be a relatively heavy movement
at all stations except New Orleans which may still be feeling the effects
of the low although it is along the coast of South Carolina. The bird
movement is earlier than usual and the weekend looks to be an interesting
one, especially along the south Texas coast.
