features
The red bearded star hummingbird reaches a body length of about 7 to 9 cm, depending on the length of its tail. The slightly curved beak makes about 15 mm. The upper side is bronze green in both sexes. The reddish purple color of the male's throat extends over the ear area. The underside is light gray with bronze green sides. The rump is cinnamon in color. The approx. 3 cm two-lobed tail consists of two outer control feathers . In the plain dress, the male's throat is pale. The female has dark cheeks with a white line behind the eyes. The yellow-brown underside has a white spot on the rump side. The short, cinnamon-colored, right-angled tail is crossed by a dark, thin band. The central control springs are also dark.
Fledglings are similar to adults but have a striped top. In the male, about a third of the tail feathers are black.

Etymology and history of research
Philip Lutley Sclater first described the red- bearded star hummingbird under the name Chætocercus burmeisteri . It was not until 1913 that Walter Edmond Clyde Todd added it to the Microstilbon genus . However, at this point he did not realize that the species had already been described by Sclater. The synonym Microstilbon insperatus also exists . The hummingbird is the only one of its kind.
The term »Microstilbon« is derived from the Greek words » mikros , μικρος « for »small« and »stilbōn, στιλβων « for »sparkle, glitter«. The Greeks gave Mercury the nickname Stilbon, which can be traced back to the verb »stilbō, στιλβω « for »blink«.
The specific epithet was awarded in honor of Hermann Burmeister (1807-1892). He had sent Sclater a water color picture of the type specimen from the Museo Argentino de Ciencias Naturales Bernardino Rivadavia . After Sclater had sought advice from Osbert Salvin and Count Hans von Berlepsch , he came to the conclusion that this was a new species.
