Illustration of S. przewalskii in worn plumage, by J.G. Keulemans

Przevalski's nuthatch (Sitta przewalskii) is a bird species in the family Sittidae. Long regarded as a subspecies of the white-cheeked nuthatch (Sitta leucopsis), it nevertheless differs significantly in morphology and vocalizations. It is a medium-sized nuthatch, measuring about 13 cm (5.1 in) in length. Its upper body is a dark gray-blue. The cheeks and throat are a white buff-orange, turning to a rich cinnamon on the underparts. The bird is endemic to areas in southeastern Tibet and west central China, inhabiting coniferous mountain forests. The species was first described in 1891 from a specimen collected in China's Haidong Prefecture. The name commemorates the Russian explorer Nikolaï Prjevalski, who discovered the species in 1884. Little is known about its ecology. It was awarded the rank of full species in 2005, separating it from the white-cheeked nuthatch. As of 2014, S. przewalskii does not have a full threat-status evaluation by BirdLife International or the IUCN. A 2014 phylogenetic study found the species to be at the base of the nuthatch evolutionary tree, dispelling a hypothesis that S. przewalskii could belong to the same species as S. carolinensis.

Ida B. Wells

Ida B. Wells (1862–1931) was an African-American journalist, newspaper editor, suffragist, sociologist, and an early leader in the civil rights movement. Born into slavery in Holly Springs, Mississippi, Wells and her family were freed by the Emancipation Proclamation of 1863. Despite losing her parents to yellow fever when she was sixteen, Wells attended Fisk University and became a teacher. Politically active since her youth, she also became a writer on race issues and campaigned against lynching; in this latter capacity she published two influential pamphlets and traveled throughout the United States and the United Kingdom. Wells also helped establish the National Association of Colored Women and the National Afro-American Council.
