Endemic to grasslands, agricultural lands and open woodlands of central and coastal California, it depends on fishless temporary ponds to breed, migrating nocturnally from upland burrows. Adults shelter in rodent burrows during dry periods.

The Lampropeltis getula, commonly known as the common kingsnake, is a non-venomous snake native to North America. It is renowned for its ability to resist the venom of other snakes, allowing it to hunt and consume them. This snake exhibits a varied coloration, often black with white or yellow bands. It can reach a length of 1.2 to 1.8 meters. The kingsnake is an opportunistic predator that feeds on rodents, birds, lizards, and other snakes. It is generally active at night and prefers habitats such as forests, grasslands, and rocky areas. Although often captured for the pet trade, it remains abundant in the wild.

The Common Redpoll, Acanthis flammea, is a small finch in the Fringillidae family. It is easily identified by its brown streaked plumage and bright red cap. Males often have a rosy breast, while females are duller. This small bird is well adapted to cold climates and is primarily found in boreal forests and arctic regions. It mainly feeds on seeds but also consumes insects in summer. The Common Redpoll is a gregarious bird, often seen in flocks, especially in winter. It is known for its irregular migrations, influenced by food availability.

The common tern is an elegant seabird easily recognized by its white plumage, light gray back, and bright red beak. It is primarily found along the coasts of Europe, Asia, and North Africa, often near estuaries and rivers. This bird is an excellent fisher, diving with precision into the water to catch fish. The common tern is also known for its swift and graceful flights.

The Common Shelduck is a large duck with a distinctive plumage, measuring between 58 and 67 cm in length. It is identified by its glossy greenish-black head, white body with a broad chestnut band, and bright red bill. Males have a prominent knob at the base of the bill, which females lack. This species inhabits estuaries, lagoons, salt marshes, tidal mudflats, and shallow lake shores, often in flocks. It nests in burrows or cavities, sometimes dug into dunes or embankments. The shelduck primarily feeds on aquatic invertebrates such as mollusks, worms, and crustaceans, filtered from the mud. While generally secure, it is vulnerable to coastal wetland destruction.

The common tenrec is a small insectivorous mammal weighing 220–270 g, with coarse fur ranging from light to dark. Endemic to Madagascar, it inhabits tropical forests, shrublands, and agricultural areas. An opportunistic omnivore, it feeds on insects, worms, and small invertebrates. Solitary and nocturnal, it shelters in burrows or under leaf litter during the day.

The Pteroglossus torquatus, known as the collared aracari, is a vibrant bird belonging to the Ramphastidae family. It is characterized by its striking plumage, predominantly black body, bright yellow chest, and distinctive red collar. Its long, curved beak is essential for feeding on fruits, insects, and occasionally small vertebrates. This toucan primarily inhabits the tropical rainforests of Central America, from southern Mexico to Panama. It is often seen in small groups, moving nimbly through the canopy. Although relatively common in its natural habitat, deforestation poses an increasing threat to its populations.

The Cyprus Wheatear, or Oenanthe cypriaca, is a small passerine bird belonging to the Muscicapidae family. This bird is endemic to the island of Cyprus, where it is often seen in open and rocky areas. It is distinguished by its black and white plumage, with a black head and a grayish back.
