Band-tailed Pigeons are the largest native pigeon species in North America. They live in mixed coniferous forests, oak woodlands, and riverside habitats. 

Their grey-blue plumage, white band on their tail, and white crescent on the nape of their neck give them a unique appearance. These birds make a distinctive three-part cooing call.

Moreover, it's an important species for the health and biodiversity of its home forests as it spreads seeds around while feeding. However, it is often considered a pest in some areas when it consumes crops.

The White-crowned Pigeon is a bird species found mainly in the Caribbean and southern Florida. It has a white crown and slate-gray body. It typically inhabits coastal mangroves and keys.

The Crested Gecko is native to the South Pacific islands of New Caledonia. A fully grown adult measures 7-9 inches and is calm and docile. These nocturnal reptiles use their semi-prehensile tail to navigate and maintain balance. 

They have distinctive hair-like protrusions above their eyes that resemble eyelashes. Their skin can showcase various colors and patterns, making them a popular choice among reptile enthusiasts. 

A crested gecko's diet includes grasshoppers, ants, spiders, crickets, worms, and the occasional fruit. Unlike other gecko species, they do not have adhesive toe pads.

The Gargoyle Gecko is native to the southern region of New Caledonia, a tropical paradise in the South Pacific. This gecko species has unique horn-like projections on its head, and its appearance resembles the gargoyles that adorn Gothic architecture. 

Likewise, its vibrant coloration can range from fiery reds and oranges to calming whites and blues, which allow it to blend into its forest surroundings.

The Gargoyle Gecko is a crepuscular species most active during dawn and dusk. It takes cover in tree crevices or under leaves during the day to protect itself from predators. As an omnivore, it feeds on insects, fruits, and small lizards. 

Its defense mechanism is to shed its tail, which distracts predators due to its continued twitching, allowing the gecko to escape. Gargoyle Geckos can regrow their tails, ready to use this mechanism again if required.

The Madagascar Ground Gecko is a small reptile species found in the diverse ecosystems of Madagascar. It has a unique color scheme that allows it to blend seamlessly into its natural surroundings. It typically measures only 4-6 inches long. 

The gecko is nocturnal and primarily feeds on small invertebrates. While it lacks adhesive toe pads, it retains mobility on the ground. 

This type of gecko defends itself through autotomy, which allows it to drop its tail to distract predators and escape. During the day, it hides in burrows or under rocks, only emerging at night to hunt for food.
