1.000 Pesos

The Banco Central de la República Argentina continues to circulate the 1,000 Pesos banknote in its Fourth Series design featuring the Rufous Hornero (Furnarius rufus), Argentina's national bird. The vibrant red-orange-yellow colored note prominently features the hornero in its natural Pampas habitat alongside native plants, bird paw prints, bird's nests, branches, and flowers that create a naturalistic representation of Pampean ecology. The reverse side showcases the geographic landscape of the Pampas region with a cartographic representation of Argentina's national territory.

The denomination was first introduced in 2017 and continued through 2023 as the highest standard circulation denomination before new higher-value notes were introduced. The 1,000 Pesos note reflects Argentina's established tradition of featuring indigenous wildlife as national symbols on its currency, celebrating biodiversity and natural heritage. The hornero is particularly beloved in Argentine culture for building elaborate mud nests and is considered a symbol of hard work and industriousness.

The banknote incorporates multiple security features including a hologram security thread, advanced printing techniques, and tamper-evident design elements. The red-orange-yellow color scheme creates distinctive visual identification, making it easily recognizable for everyday transactions. Argentina's ongoing currency challenges — including significant inflation — led to the rapid introduction of higher denominations alongside continued circulation of the 1,000 Pesos note.
