Shrikes are passerine birds known for their habit of catching other birds and small animals and impaling the uneaten portions of their bodies on thorns. A shrike's beak is hooked, like that of a typical bird of prey. Two species have been recorded in Virginia. Loggerhead shrike, Lanius ludovicianus; Northern shrike, Lanius borealis (R)

Only animals from the classes of the Chordata phylum are included. [1] On average, captive animals (especially mammals ) live longer than wild animals. This may be due to the fact that with proper treatment , captivity can provide refuge against diseases , competition with others of the same species and predators .
Some tortoises show negligible senescence. Negligible senescence is a term coined by biogerontologist Caleb Finch to denote organisms that do not exhibit evidence of biological aging (), such as measurable reductions in their reproductive capability, measurable functional decline, or rising death rates with age.

Of all evaluated avian species, 4% are listed as endangered. No subpopulations of birds have been evaluated by the IUCN. For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of extinction".
According to the International Union for Conservation of Nature (IUCN), 77 bird species in the United States are threatened with extinction. [1] The IUCN has classified each of these species into one of three conservation statuses: vulnerable VU, endangered EN, and critically endangered CR (v. 2013.2, the data is current as of March 5, 2014 [1]).
The best solution is generally dependent on the particular species or ecosystem that is being considered. More mobile species, like most birds, do not need connected habitat while some smaller animals, like rodents, may be more exposed to predation in open land. These questions generally fall under the headings of metapopulations island ...
