The long-term social unit of the plains viscacha is the female group. Resident males disappear each year and new males join groups of females. Viscachas live in colonies that range from a few individuals to hundreds. To keep up with the colony chatter, they have acquired an impressive repertoire of vocalizations that are used in social ...

In Pennsylvania, three subadult eastern meadow voles were captured at least 1.6 miles (2.6 km) from the nearest appreciable suitable eastern meadow vole habitat, suggesting they are adapted to long-distance dispersal. [21] In Ohio, the effects of patch shape and proportion of edge were investigated by mowing strips between study plots.
Eusocial insects like ants and honey bees are multicellular animals that live in colonies with a highly organized social structure. Colonies of some social insects may be deemed superorganisms. [6] Animals, such as humans and rodents, form breeding or nesting colonies, potentially for more successful mating and to better protect offspring.
In contrast to state reptiles, state birds have been more rapidly adopted, with the first state designating one in 1927 and the fiftieth in 1973. [78] As of January 2011, other types of animals more popular for state symbolization were mammals (46), [ 79 ] fish (45), [ 80 ] and insects (42). [ 81 ]
Out of Pennsylvania’s 21 species of snake only three are venomous. Two are found in the central region. Julian Avery from Penn State explains what to look for.
