Tundra Swan (Cygnus columbianus), Palo Verde, Maricopa County
Adult Tundra Swan photographed by Jim Burns in Palo Verde Arizona about a half mile east of Palo Verde on Baseline Road feeding in a field on the north side of the road. This is a Tundra Swan because of the diagnostic small yellow spot on the facial skin near the eye.
Although not a review or sketch details species,
there was a controversial immature swan in Palo Verde
last year that some thought was a Trumpeter Swan.
This may be the same bird from last year returning as an
adult, which in turn suggests the possibility that the
controversial immature swan from last year was a Tundra,
the expected swan in Arizona.
