Dan Tallman, a bird-bander and retired biology professor in Minnesota has
an excellent bird blog where he reasons through the distinguishing field
marks of female/immature MacGillivray's and Mourning Warbler . When the
photos were originally taken of the Dyke Marsh bird , his comparisons were
very helpful. See

Reviewing Dave Boltz's great picture and the ones I had taken a day
earlier, MacGillivray's Warbler was the correct ID.
Last year at Highspire Park, Pennsylvania a Geothlypis warbler was observed
closely and sparked the same debate as occurred with the Dyke Marsh warbler.
They ultimately concluded that it was Pennsylvania's second confirmed
sighting of this western species.
