Enclosed is a link to my recent blog post giving the latest information I have on the Rufous hummingbirds that have been banded in east Tennessee by Mark Armstrong, including one that was banded this past Sunday, following the record-breaking cold. The summary is interesting given that we often feel that these birds can not survive such extreme weather conditions. http://vickiehenderson.blogspot.com/2014/01/hardy-hummingbirds-survive-polar-vortex.html Vickie Henderson Knoxville, TN Knox County http://vickiehenderson.blogspot.com/ http://vickiehendersonsketchbook.blogspot.com/ http://vickiehenderson.com/ http://discoverbirds.blogspot.com/
