Pennsylvania Game News - March 2015 - 53
canvasbacks do exist from earlier
times.
Canvasbacks and redheads
declined precipitously in the
20th century because prairie
wetlands where they
breed were drained.
In addition,
their breeding
grounds faced
droughts and
too many ducks
were harvested in hunting
seasons, but lately their
numbers have rebounded
due to conservation efforts.
When we left the observatory, we
returned to the picnic grounds for a
late lunch and enjoyed watching the
small wetland area along the shore.
Three blue-winged teal poked in
a puddle and ignored us as we moved
close to observe them. The male's
white facial crescent easily identified
him, but both sexes display the large,
chalky-blue patch on their forewings
that gives them their name.
Even though the blue-winged teal
is abundant in North America, it
has declined as a breeding species in
Pennsylvania, from 29 confirmed in
the first atlas to 11 in the second.
The amount of temporary wetlands
in healthy grasslands - their preferred
breeding habitat - has been dwindling
in Pennsylvania.
Other bird species like northern
harriers and spotted sandpipers, which
breed in the same habitat, also are
declining.
Still, we always see a pair of bluewinged teal when we visit Yellow
Creek State Park.
Near the wetland area swam a raft
of common mergansers - males with

white bodies, black backs, and dark
green heads, and the equally striking
gray-bodied females, with white
breasts and chins and red-crested
heads.
Common mergansers nest in
Pennsylvania, especially along forested
rivers and their confirmed breeding
numbers increased from 119 in the
first atlas to 241 in the second, due to
"clean, biologically productive rivers
and streams," Jacobs writes, as well as
"forest maturation in Pennsylvania
and the resulting increase in large
trees..." where they nest.
Altogether, we had long and close
looks at 10 duck species, as well as the
greater yellowlegs, American coots,
a belted kingfisher, Canada geese,
tundra swans, killdeer, herring gulls
and great blue herons.
As usual, at Yellow Creek State
Park, I had had a productive day
that amply soothed my "waterfowl
itch."
