The pictures below come from the large dead tree near the parking lot at Donner Camp on Alder Creek, north of Lake Tahoe, with a sign at its foot commemorating the Donner party, some of whom died nearby in the winter of 1846-47. In the summers of 2008 and 2009, a pair of Pygmy Nuthatches nested in a hole in this snag.

Pygmy Nuthatch removing fecal sac, 622/09, Donner Camp, Nevada Co
Nestlings defecate in neatly sealed sacs, greatly facilitating maintenance of nest hygiene. This was the only time I'd ever seen a fecal sac actually passed from a nestling of any species to an adult.
