The Puerto Rican amazon (Amazona vittata), is an endemicparrot of the archipelago of Puerto Rico belonging to the neotropical genus Amazona. Measuring 28–30 cm (11–12 in), the Puerto Rican Amazon is predominantly green with a red forehead and white rings around the eyes. Two subspecies have been described, although there are doubts over the distinctiveness of the form gracilipes from Culebra Island, extinct since 1912. Its closest relatives are believed to be the Jamaican Black-billed amazon (Amazona agilis) and the Hispaniolan amazon (Amazona ventralis). The species is the only remaining native parrot in Puerto Rico and one of the ten most endangered bird species in the world. Initially widespread and abundant, the population declined drastically in the 19th and early 20th centuries with the removal of most of its native habitat, also vanishing from nearby Vieques Island and Mona Island. Conservation efforts were started in 1968 to save this species from likely extinction. As of 2008, the total wild population is estimated to be between 30 and 35 individuals. (more...)

Dolores "Lolita" Lebrón Sotomayor (November 19, 1919 – August 1, 2010) was an active advocate for Puerto Ricanindependence. She was born and raised in Lares, Puerto Rico, where she joined the Liberal Party. In 1941, Lebron migrated to New York City, where she joined the Puerto Rican Nationalist Party, gaining influence within the party's leadership. In 1952, after Puerto Rico's official status was changed to "Commonwealth", the Nationalist Party began a series of revolutionary actions, including the Jayuya Uprising. As part of this initiative, Pedro Albizu Campos ordered her to organize attacks in the United States, focusing on locations that were "the most strategic to the enemy". She became the leader of a group of nationalists, who proceeded to attack the United States House of Representatives in 1954. Lebron remained imprisoned 25 years, when Jimmy Carter issued pardons to the group involved. During the following years she continued her involvement in pro-independence activities, including the Navy-Vieques protests. (more...)
