Crested caracara

life science Maturity 5-7 Next article →

The crested caracara, known scientifically as Caracara plancus, is a highly adaptable bird of prey. It belongs to the falcon family, which is called Falconidae. This species is considered a raptor, a term for birds that hunt other animals. Caracaras are famous for being extremely hardy and versatile. They can thrive in many different ecosystems. These include semi-arid deserts, coastal maritime areas, and tropical forests. They are even found in urban areas near humans. Because they can live in so many places, they are considered a species of least concern by BirdLife International.

To understand how the crested caracara survives, you must look at its unique hunting behavior. It is an opportunistic feeder, meaning it takes whatever food is available. Much of its time is spent walking on the ground to search for meals. While it often eats the carcasses of dead animals, it is also a skilled thief. It practices a behavior called kleptoparasitism, where it steals food from other birds. The caracara may chase vultures, pelicans, or ibises until they drop their food. It can also take live prey like insects, small mammals, fish, or even crabs. Some caracaras have even learned to follow cars or trains to find food thrown out by people.

Scientists divide the crested caracara into two distinct subspecies. The first is C. p. cheriway, often called the northern crested caracara. This subspecies lives in the southern United States, Mexico, Central America, and parts of the Caribbean. The second is C. p. plancus, which lives in the southern part of its range. This group is found in southeastern Peru, northern Bolivia, eastern Brazil, and as far south as Tierra del Fuego. Interestingly, birds in the colder southern regions tend to be larger. This follows Bergmann's rule, which suggests that animals in colder climates often have larger body masses. In fact, the southern caracara is the second-largest falcon in the world, following only the gyrfalcon.

The history of how we name and study this bird is quite long. In 1777, an English illustrator named John Frederick Miller first gave it the name Falco plancus. He published these findings in his work titled Icones animalium et plantarum. The specific name "plancus" is the Latin word for eagle. Later, in 1826, a German naturalist named Blasius Merrem introduced the genus name Caracara. There is also a historical debate regarding the "Mexican eagle." In 1960, a proposal suggested that the bird in ancient Aztec imagery was actually a caracara. However, the golden eagle remains the official national animal and symbol of Mexico.

Physical measurements help us understand the scale of these impressive birds. A crested caracara has a total length of about 55 to 65 centimeters. Its wingspan ranges from 110 to 125 centimeters. The weight of the bird typically stays between 1.1 and 1.4 kilograms. Their appearance is very striking with dark brownish feathers on their cap and belly. They have whitish-buff feathers on their throat and neck. One of their most interesting features is their bright yellow legs. Their facial skin and cere, which is the fleshy area above the beak, are deep yellow or reddish-orange. This facial color can actually change based on the bird's mood.

The caracara has a very interesting relationship with its environment in Florida. A specific population lives there that dates back to the last glacial period. This period ended approximately 12,500 years ago. During that time, the landscape was an oak savanna. As the climate warmed, the savanna disappeared, but the caracaras stayed in the marshes and prairies. They often choose cabbage palmettos or live oaks for their nests. While they are common in many areas, they are currently listed as threatened in certain parts of the Florida coast. They must also watch out for invasive predators, such as various species of large pythons.

Beyond their biology, caracaras connect to many different parts of the natural world. Their presence can be linked to human activity, such as farming or even wildfires. They often follow the smoke of a wildfire to find prey that has been flushed out of hiding. They also interact closely with other scavengers. For example, there are recorded instances of black vultures approaching a caracara to preen it. This happens when the caracara bows its head as an invitation. This social interaction shows how these birds fit into the complex web of life in the Americas.
