Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Yellow-shouldered Blackbird (Agelaius xanthomus), also known as La Mariquita de Puerto Rico or Capitán, is a diurnal blackbird endemic to the archipelago of Puerto Rico and one of the eleven species belonging to the Agelaius genus of the Icteridae family. The Yellow-shouldered Blackbird, as its name implies, is a glossy black bird with a small yellow humeral patch around its "shoulders" outlined by a white margin. Immature individuals possess a duller coloration and a brown abdomen. Although plumage coloration is indistinguishable between the sexes, sexual dimorphism is present in this species with males being larger than females. Plumage abnormality is rare in this species. Adult individuals measure from 20 to 23 cm; on average, males weigh 41 g and females weigh 35 g. Sexual categorization may also be made by measurement of the wings, with males'' being 1.1 times larger and having a mean length of 102.8 mm ,while females'' wings have an average length of 93.3 mm.
