Question: George and Martha is about a pair of animals that are typically native to what area?
Context: Animal Science (also Animal Bioscience) is described as "studying the biology of animals that are under the control of humankind".  Historically, the degree was called animal husbandry and the animals studied were livestock species, like cattle, sheep, pigs, poultry, and horses. Today, courses available now look at a far broader area to include companion animals like dogs and cats, and many exotic species.  Degrees in Animal Science are offered at a number of colleges and universities.  In the United States, the universities offering such a program were Land Grant Universities and include University of Nebraska–Lincoln, Cornell University, UC Davis, Michigan State University, Purdue University, The Ohio State University, The Pennsylvania State University, Iowa State University and the University of Minnesota. In Tanzania the program offered at sokoine university .  Typically, the Animal Science curriculum not only provides a strong science background, but also hands-on experience working with animals on campus-based farms. The common hippopotamus ("Hippopotamus amphibius"), or hippo, is a large, mostly herbivorous and aggressive mammal in sub-Saharan Africa, and one of only two extant species in the family Hippopotamidae, the other being the pygmy hippopotamus ("Choeropsis liberiensis" or "Hexaprotodon liberiensis").  The name comes from the ancient Greek for "river horse" (ἱπποπόταμος ).  After the elephant and rhinoceros, the common hippopotamus is the third-largest type of land mammal and the heaviest extant artiodactyl.  Despite their physical resemblance to pigs and other terrestrial even-toed ungulates, the closest living relatives of the Hippopotamidae are cetaceans (whales, dolphins, porpoises, etc.) from which they diverged about .  The common ancestor of whales and hippos split from other even-toed ungulates around .  The earliest known hippopotamus fossils, belonging to the genus "Kenyapotamus" in Africa, date to around . Grazing pressure is the stress on plant populations due to the grazing of animals.  Plants may be lost either directly as a result of animals grazing upon them, or indirectly as a result of damage to the vegetation or ecosystem by animals moving through the area.  Usually the term refers to introduced pastoral animals such as cattle and sheep, but in some contexts it may mean introduced feral animals, or even native animals. The Sulphur Creek Nature Center is a nature center and wildlife rehabilitation center located in Hayward, California.  They are managed by the Hayward Area Recreation and Park District.  The center has facilities for taking in and providing medical and rehabilitation services for wild animals, including mammals and birds, and a small display of San Francisco Bay Area native reptiles and amphibians.  The center is an educational site for local elementary schools.  Small domesticated animals are available for home rental, while the center itself has free admission.  The site is adjacent to Sulphur Creek, a tributary of San Lorenzo Creek.  They treat up to 900 wild animals a year and installed a webcam for observing a barn owl family. Alaskan Natives have a special connection to the land around them, and a kinship with the animals with whom they share that land.  Before the introduction of western culture and the religions that are now practiced in Alaska, there was a common spiritual connection made with the people to the land they occupied.  The most common name for this connection is shamanism.  Shamanism differs in every culture where it is practiced, in Alaska it is centered in the animals that are common in the area.  Through the use of many myths, stories, and ceremonies these animals are personified and their spirits made tangible and in turn are deeply woven within the Native Alaskan people today.  It was through the shaman that the spirit world was connected to the natural world.  A shaman in Alaskan Native culture was a mediator, healer and the spirit worlds’ mouthpiece.  Although shamanism is no longer popularly practiced, it was and continues, to be the heart of the Native Alaskan people. The bronzes tend to be flat and use openwork, like the related metalwork of Scythian art.  They represent the art of a nomadic or transhumant people, for whom all possessions needed to be light and portable, and necessary objects such as weapons, finials (perhaps for tent-poles), horse-harness fittings, pins, cups and small fittings are highly decorated over their small surface area.  Representations of animals are common, especially goats or sheep with large horns, and the forms and styles are distinctive and inventive.  The "Master of Animals" motif, showing a human positioned between and grasping two confronted animals is common but typically highly stylized.  Some female "mistress of animals" are seen. Social grooming is a behaviour in which social animals, including humans, clean or maintain one another's body or appearance.  A related term, allogrooming, indicates social grooming between members of the same species.  Grooming is a major social activity, and a means by which animals who live in close proximity may bond and reinforce social structures, family links, or build relationships. Social grooming is also used as a means of conflict resolution and reconciliation in some species.  Mutual grooming typically describes the act of grooming between two individuals, often as a part of social grooming, pair bonding, or a precoital activity. Osteen is an unincorporated community in southwest Volusia County, Florida, United States.  Osteen is near the St. Johns River as well as typically native wetlands, swamps, forests and wildlife of Florida.  Osteen attracts a number of visitors for these qualities.  There are numerous camping areas and preserves such as the Hickory Bluff Preserve, a 150-acre nature preserve with hiking and horse trails. Golden eagles usually mate for life.  A breeding pair is formed in a courtship display.  This courtship includes undulating displays by both in the pair, with the male bird picking up a piece of rock and dropping it only to enter into a steep dive and catch it in mid-air, repeating the maneuver 3 or more times.  The female takes a clump of earth and drops and catches it in the same fashion.  Small sticks may also be used in this display.  Compared to the bald eagle, golden eagles do not repeat courtship displays annually (which is believed to strengthen pair bonds) and rarely engage in talon-locking downward spirals.  Golden eagles typically build several eyries within their territory and use them alternately for several years.  Their nesting areas are characterized by the extreme regularity of the nest spacing.  In 9 studies of annual nest spacing, the average minimum distance between nests range from 16 km apart in Norway to 8 km apart in Switzerland.  Nests in Scotland may found at anywhere from 10 to 65 pairs per 1000 km2 , with an average of over 20 pairs found per area.  In much of continental Europe, densities of less than 10 pairs per 1000 km2 are typical.  In the United States different areas had from 10 to more than 20 pairs on average per 1000 km2 .  Wyoming had the greatest densities of breeding golden eagles of any complied study, though numbers were comparable to western Scotland as there were an average of just over 20 pairs per 1000 km2 , with greatest estimated densities of possibly 125 per area.  In Wyoming, the distance between nests ranged from 3.1 to , averaging 5.3 km .  In the wooded peatlands of Sweden and Belarus, a maximum of 5 pairs appear to occur per 1000 km2 .  In Quebec, the distance between nests ranged from 8 to .  In the Snake River canyon in Idaho, nests are 5 to apart, while two other nearby studies in Idaho found the average distance were 4.3 km and 4.39 km , respectively.  The nesting density for a breeding population near Livermore, California, and the Altamont Pass Wind Farm is among the highest in the world for golden eagles, with at least 44 pairs in 1997, a density of one pair per 19 km .  Due to the consistency of use by golden eagle pairs, population densities change generally happens only quite gradually. George and Martha is a series of children's books written and illustrated by James Marshall between 1972 and 1988.  Each book in the series contained a number of short stories describing interactions between two hippos, George and Martha.  The books inspired an animated children's television show which comprised 26 episodes made in 1999, and a musical in 2011.
