The Groove-billed Ani  is an odd-looking tropical bird in the cuckoo family with a long tail and a large, curved beak. It is a resident species throughout most of its range, from southern Texas, central Mexico and The Bahamas, through Central America, to northern Colombia and Venezuela, and coastal Ecuador and Peru. It only retreats from the northern limits of its range in Texas and northern Mexico during winter.

The groove-billed ani is about 34 cm long, and weighs 70–90g. It is completely black, with a very long tail almost as long as its body. It has a huge bill with horizontal grooves along the length of the upper mandible. It is very similar to the smooth-billed ani, some of which have bills as small as the groove-billed and with grooves on the basal half. The two species are best distinguished by voice and range. In flight, the ani alternates between quick, choppy flaps and short glides.

The Slender-billed Finch is a species of finch-like bird traditionally placed in the Emberizidae family, but it may be more closely related to the Thraupidae. It is restricted to southwest Peru and northern Chile, and inhabits mainly riverine vegetation along coastal valleys. It has been considered endangered due to loss of habitat. Riparian thickets that were common are under pressure from logging by farm owners. Some information has indicated that it has adapted to threats using olive trees areas and other artificial habitats successfully.
