Yellow-backed duiker
These forest dwelling antelope feed selectively on plants or plant parts such as shoots, roots, leaves, and buds, but their diet is mainly made up of fruits. The yellow-backed duiker is more efficient at digesting poor quality food than most other duiker species. This allows them to eat large, low quality fruits. Their diet makes them very hard to keep in captivity as most domesticated fruits are not well suited to their low fiber requirements. They are considered concentrate selectors, meaning they eat "diets relatively low in fiber, have a well developed ability to forage selectively, a rumen bypass, a rapid passage and high fermentation rate for starch, and they frequently encounter toxins."
Antillean piculet
The Antillean piculet feeds on insects, with ants and beetles forming a large part of the diet. They also consume a lot of fruit compared to other piculets. Individuals and pairs forage rapidly through the understory of their habitat, mostly on small branches, twigs, vines and stalks, and less commonly on trunks. Food is mostly obtained by gleaning, with a few weak pecks (but no hammering as found in the true woodpeckers). The breeding season of the Antillean piculet is March to July. A cavity is excavated in a stump, tree, palm or fence post in which two to four eggs are laid. The pair are highly territorial and will aggressively call and display towards intruders.
