The Brazilian Social Democracy Party (Portuguese: 'Partido da Social Democracia Brasileira', PSDB), is also known as the Brazilian Social Democratic Party or the Party of Brazilian Social Democrats. It is one of the largest and most significant political parties in Brazil. The PSDB's mascot is a blue and yellow colored toucan, with party members being called 'tucanos' for this reason.

Toucans are members of the Neotropical near passerine bird family 'Ramphastidae'. They are brightly marked and have large, often colorful bills. The family includes five genera and over forty different species. The name of this bird group is derived from the Tupi word 'tukana', via Portuguese. Toucans are native to the Neotropics, from Southern Mexico, through Central America, into South America south to northern Argentina.
