Horned sungem

The horned sungem (Heliactin bilophus) is a species of hummingbird native to Brazil, Bolivia and Suriname. It prefers open habitats such as savanna, grassland and garden, and expanded its range into southern Amazonas and Espírito Santo, probably due to deforestation. It is a small hummingbird with a long tail and a short, black bill. The sexes differ in appearance, with males having two shiny red, golden, and green feather "horns" above the eyes, a shiny blue head crest and a black throat with a pointed "beard". The female is plainer, with a brown or yellow–buff throat. It is a nomadic species, responding to the seasonal flowering of its food plants. If a flower's shape is unsuited to the bird's short bill, it may rob nectar through a hole at its base. It also eats small insects. Only the female builds the small cup nest, incubates the two white eggs, and rears the chicks. The species is currently classified as least concern, and its population is thought to be increasing.

Acorn woodpecker

The acorn woodpecker (Melanerpes formicivorus) is a bird in the woodpecker family, Picidae. It is found across Central America, as well as the western United States and parts of Colombia. A medium-sized bird, it has a length of around 20 cm and is mostly black, and adult males have a red cap starting at the forehead and females a black area between the forehead and the cap. As their name implies, acorn woodpeckers are heavily dependent on acorns for food, which they store in small holes that they drill into trees, known as "granaries" or "storage trees". This acorn woodpecker was photographed in the grounds of California State University, Chico, United States.
