This colorful Paraguayan stamp features the Yellow-headed Amazon (Amazona oratrix), known in Spanish as "Amazon Cabeza Amarilla." Issued as part of a commemorative series for the centenary of the Epopeya Nacional de 1864–1870 (the War of the Triple Alliance), it pairs natural beauty with national remembrance. The bird is vividly illustrated with green plumage, a striking yellow head, and red-and-blue wing feathers. Designed by Claudio Alonso and printed by De La Rue de Colombia, this 0.75 guaraní issue is a favorite among thematic collectors of parrots and Latin American fauna.
