14 September 2010 – Mourning Warbler

Yet another Mourning Warbler has met its end on one of the west alcoves of the Noble Research Center. This one is a hatch year bird of undetermined sex (though the faint orangey wash to the yellow on the upper breast has me thinking it’s a male). This bird was also in prime condition for migration: fat score = 3.

I can’t tell if the damage to its right foot was caused by one catastrophic bump against the glass or if this was one of the poor birds who struggled against the building for hours before exhausting itself. The latter scenario is unlikely given the amount of fat the bird still had.
