Mainland Darwin's finch (SciiFii)

The mainland Darwin's finch (Geospiza americanum) is a species of bird in the family Thraupidae and one of the Darwin's finches that originally did not exist, but has since been created by SciiFii and introduced throughout the rainforests, wetlands, forests, open woodlands, grasslands, shrublands, and scrublands across mainland North America and South America to help boost biodiversity. Like the other members of its genus, the mainland Darwin's finch is strongly sexually dimorphic; the female's plumage is brown and streaky, while male's is solid black, with white tips to the undertail coverts. The bird measures 12.5 cm (4.9 inches) in length—which falls between the lengths of the small and large ground finches of the Galapagos. The bill of this species is quite variable in size, though the length of the upper mandible is always greater than the depth of the bill at its base. The males have shorter, rounder wings, which help with maneuvering around a female during sexual displays. As with other Darwin's finches, the mainland Darwin's finch males have short, yet repetitive songs. The mainland Darwin's finchs' songs are almost identical to the songs made by the medium ground finch (Geospiza fortis) and the songs made by the Española cactus finch (Geospiza conirostris), both Galapagos natives. The mainland Darwin's finch feeds primarily on seeds, although it is also known to eat flowers, buds, and young leaves, and the occasional insect. It forages either on the ground or in low vegetation. Mainland Darwin's finches build display domed nests and use these to attract mates and for nesting. Male mainland Darwin's finches will sing close to their nest once it has been built, to attract female small tree finches. When these arrive, they inspect the display nest by entering it. Thereafter they will either choose to accept both the male and the display nest, accept the male but reject the nest (so they will then build a new nest together), or reject both the male and the display nest. The standard clutch is two or three brown-spotted white eggs. The conservation status of the mainland Darwin's finch is Least Concern due to successful conservation efforts, the mainland Darwin's finch's wide range and its tolerance to many of the human activities.
