List of animals and The study of animal behavior called ethology

The study of animal behavior, called etiology, is a broad field, encompassing both instinctual and learned behaviors as well as abnormal behaviors. Within any particular species of animal, certain behaviors may be present in all members while others are more specific to certain individuals, locations or situations. Even the most simple of life forms exhibit behavioral activity, and whether the behavior is normal or abnormal can provide insight into their mental state.

The Instinctual behavior

A chick peeks out from a protective wing.

One type of instinctual behavior is fixed action patterns, which are behaviors the animal is compelled to engage in. For instance, some birds will raise the chicks of other birds if the eggs are put in their nests during nesting season because caring for an egg is a fixed action pattern. Another instinctual behavior is imprinting, wherein a baby animal accepts a person, or even an item, as a surrogate mother. Sexual behavior is also instinctual, bolstered by play, which helps animals learn courtship and mating skills. Many of these behaviors are dictated by specific body systems, like the nervous system, which response to stimuli in the environment.

Learning Behaviors


Learned behavior is important both for wild animals, who must learn specific and new ways to survive and for domestic animals that we seek to train. Animals can learn to anticipate that an action will have a predictable outcome through trial and error, such as dog learning to sit for a treat. This is called operant conditioning. They can also learn that one event precedes another, such as the sound of a metal food bowl being moved signaling food being served, which is known as associative learning. Animals also learn a lot by watching others and mimicry. All of these behaviors allow an animal to adapt to new situations and problems.

The Abnormal behavior

Penguins engage in a mating ritual.

Identifying behavior patterns enables people to determine when animals are behaving abnormally. These abnormal behaviors might simply be annoying to animal owners; however, in other instances, they may also be dangerous for the animal and others or even threaten their very survival. For example, inappropriately aggressive dogs, which might be suffering from disease or trauma, are potentially dangerous to themselves and others. The behavior may be addressed if it is identified as abnormal and normal behavior is reestablished. More important to species survival are mating and raising offspring, and in these cases, abnormal behavior that leads to failure to mate or care for offspring can present a threat to the animal's long-term survival.

brief history of cross-river state

Image
Cross River State is a coastal state in South Eastern Nigeria, named after the Cross River, which passes through the state. Located in the Niger Delta, Cross River State occupies 20,156 square kilometers. It shares boundaries with Benue State to the north, Enugu and Abia States to the west, to the east by the Cameroon Republic and to the south by Akwa-Ibom and the Atlantic Ocean. During the European scramble for Africa, Queen Victoria signed a Treaty of Protection with the King and Chiefs of Akwa Akpa, known to Europeans as Old Calabar on 10 September 1884. This enabled the United Kingdom to exercise control over the entire territory around Calabar, including Bakassi. The territory subsequently became de facto part of Nigeria, although the border was never permanently delineated. However, documents released by the Cameroonians, in parity with that of the British and Germans, clearly places Bakassi under Cameroonian Territory as a consequence of colonial-era Anglo-German agreements....

Lessons from the Night the Stars Fell 181 Years Ago

Image
heavens with thousands upon thousands of incandescent dots shortly after sunset on Nov. 12, 1833.  Through the small hours of the night and into the wee hours of the morning the glowing matter seemed to wait as if on cue, suspended on the onyx canvas. Several hours before the sun rose, the first star fell.  Then it was as if the heavens collapsed. People who witnessed the astonishing display across North America spoke of it even decades later with eyes wide and a quiver in the voice. “It seemed as if the whole starry heavens had congregated at one point near the zenith and were simultaneously shooting forth, with the velocity of lightning, to every part of the horizon, and yet they were not exhausted—thousands swiftly followed in the track of thousands, as if created for the occasion,” testified an onlooker. “Never did rain fall much thicker than the meteors fell toward the earth; east, west, north, and south, it was the same,” said another. “In a word, the whole ...
