Rescue Behaviour
Rescue behaviour is a form of altruistic behaviour shown by animals where an individual in distress is aided appropriately by another individual which puts itself at risk in the process. The term "rescue behaviour" was first introduced in the title and in the text of a paper by Wojciech Czechowski, Ewa Joanna Godzińska and Marek Kozłowski (2002) that reported the results of field observations and experiments documenting this behaviour in workers of three ant species, Formica sanguinea, Formica fusca and Formica cinerea that were observed to try to rescue individuals captured by antlion larvae (Myrmeleon formicarius). Criteria allowing to tell apart rescue behaviour from other forms of cooperation and altruism were subsequently provided by Elise Nowbahari and Karen L. Hollis. Rescue behaviour has been demonstrated in a very limited range of animals that include ants, primates including humans, a few bird species, such as the Australian magpie, and wild boar.

Altruism (biology)
In biology, altruism refers to behaviour by an individual that increases the fitness of another individual while decreasing the fitness of the agent. Altruism in this sense is different from the philosophical concept of altruism, in which an action would only be called "altruistic" if it was done with the conscious intention of helping another. In the behavioural sense, there is no such requirement. As such, it is not evaluated in moral terms—it is the consequences of an action for reproductive fitness that determine whether the action is considered altruistic, not the intentions, if any, with which the action is performed. The term altruism was coined by the French philosopher Auguste Comte in French, as ''altruisme'', for an antonym of egoism. He derived it from the Italian ''altrui'', which in turn was derived from Latin ''alteri'', meaning "other people" or "somebody else". Altruistic behaviours appear most obviously in kin relationships, such as in parenting, but may also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Magpie
The Australian magpie (''Gymnorhina tibicen'') is a black and white passerine bird native to Australia and southern New Guinea. Although once considered to be three separate species, it is now considered to be one, with nine recognised subspecies. A member of the Artamidae, the Australian magpie is placed in its own genus ''Gymnorhina'' and is most closely related to the black butcherbird (''Melloria quoyi''). It is not closely related to the European magpie, which is a corvid. The adult Australian magpie is a fairly robust bird ranging from in length, with black and white plumage, gold brown eyes and a solid wedge-shaped bluish-white and black bill. The male and female are similar in appearance, but can be distinguished by differences in back markings. The male has pure white feathers on the back of the head and the female has white blending to grey feathers on the back of the head. With its long legs, the Australian magpie walks rather than waddles or hops and spends ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
