[1][2] She was one of a group of ornithologists who discovered a previously undocumented species of swamp bird, Formicivora acutirostris.
[4] In 1995, she was working on the Parana coast with colleagues Dante Teixeira and Marcos Bonrnschien when they discovered an undocumented bird.
[5] The taboa swamp that the bird lived in was being encroached on by human activities, so in 2008 Reinert and others formed an organisation to create a nature reserve in nearby Guaratuba.
[7] In 2015, a species of toad found in Brazil, Melanophryniscus biancae, was named in her honor due to her conservation efforts.
[8] Reinert collaborated with poet, Adélia Maria Woellner, and illustrator, Kitty Harvill to produce a picture book, A descoberta do Bicudinho-do-Brejo, which is about S. acutirostris and was released in July 2018.
