Monte Yellow-Finch

The Monte Yellow Finch has a vibrant yellow body, measures 13.5-14 cm, and weighs 16.5–19.8 g. However, the size of the bird doesn't differ between males and females; the colors do. The male Monte Yellow Finch, specifically the breeding male, is bright yellow. The underparts are also very bright yellow and can have a more olive-colored tint in their feathers. During the winter, the male feathers have a grey color, and their tail is shorter than usual. This is one key identifier for the Monte Yellow Finch. The female Monte Yellow Finch can closely resemble or be mistaken for a Patagonian Yellow Finch(Sicalis lebruni), but the olive color tint on the rump of the body differs from the rump coloration of different species. However, the Monte Yellow Finch newborn has a golden yellow head, grey lore's, and a yellow olive mantle.

The Monte Finch can be located in the Monte Desert in the Catamarca province of Argentina. The Catamarca province is in western Argentina. Larrea Cuneifolia, a South American bush-like plant with yellow and white flowers, has been associated with the Monte Yellow Finch. They are often observed sitting on top of this plant. The species gathers at bodies of water, especially in desert settings, and can be observed in canyon environments.

The Monte Yellow Finch diet consists of 99.5 percent seeds, and .5 percent is arthropods. It collects their food in the trees or on the ground. The species is primarily granivorous, feeding almost entirely on seeds during the winter months.
