White-breasted Nuthatch
Sitta carolinensis
The White-breasted Nuthatch (Sitta carolinensis) is a resident across much of the United States, Canada and Mexico. It is a species which inhabits quite a variety of mixed forest types at all elevations. It is often seen hopping around a tree trunk, head downward. The first image here was taken near Winnipeg, Manitoba, Canada, in November, 1998, with a Canon EOS 1N and EF 300mm F/2.8 L lens and 2X extender on Fuji Sensia film.
The next two shots of White-breasted Nuthatch were taken in Breckenridge, Summit Co., Colorado, in June, 2007, with a Canon EOS 1D Mark III and EF 500mm F/4 L IS lens and 2X extender.
The White-breasted Nuthatch in the next 7 images was on Wichita Mountains N.W.R., Comanche Co., Oklahoma, in April, 2008. These shots were taken with a Canon EOS 40D and an EF 600mm F/4 l IS lens and 1.4X extender.
