MARE NOSTRUM AT NIGHT

Source: El Blog de Fran.

Aunque conocemos lo básico de las más de 15.000 especies animales que habitan en el Mar Mediterráneo, ignoramos el comportamiento natural incluso de las más comunes, dado que muchas comienzan su actividad al caer el sol.

En el mediterráneo las diferentes fases lunares no afectan seriamente a las mareas, pero si lo hacen al comportamiento de muchos animales: Amparados por el oscuro manto de la noche, infinidad de especies se activan para relacionarse o buscar alimento sin ser devoradas.

Muchas han desarrollado habilidades y órganos sensoriales extraordinarios para sobrevivir al próximo amanecer. Otras utilizan la furtividad de la noche para reproducirse en las templadas aguas del Mare Nostrum. [YouYube, subido por New Atlantis]

Though we know the basic of more than the 15.000 animal species that live in the Mediterranean Sea, we ignore the natural behaviour of the most common ones, because many of them begin its activity after dark.

In the Mediterranean Sea the different lunar phases do not affect seriously to tides, but they seriously do to the behaviour of many animals.

Protected by the dark mantle of the night, infinite number of species activate at night in search of food, without being devoured.

Many have developed skills and extraordinary sensory organs to survive the next dawn. Others, covered by the night, find mate to reproduce in the template waters of the Mare Nostrum. [YouTube, uploaded by New Atlantis]

CHICKEN INTELLIGENCE

The mental abilities of animals—particularly birds—have traditionally been underestimated. However, as we take the time to study what birds are really like, their intelligence and complex lives become very obvious.

 

Here’s what the experts say about chickens:

Dr. Lesley Rogers, Professor of Zoology at University of New England, Australia 

“[I]t is now clear that birds have cognitive capacities equivalent to those of mammals, even primates.” 

Rogers LJ, The Development of Brain and Behaviour in the Chicken (Wallingford, Oxon, U.K.: CABI Publishing, 1995, p. 217).

Dr. Joy Mench, Professor of Animal Science at University of California at Davis 

“Dr. Joy Mench, Professor and Director of the Center for Animal Welfare at the Univ. of Calif. at Davis explains, ‘Chickens show sophisticated social behavior….That’s what a pecking order is all about. They can recognize more than a hundred other chickens and remember them. They have more than thirty types of vocalizations.’” 

Specter M, “The Extremist,” The New Yorker, April 14, 2003, p. 64.

Dr. Chris Evans, Professor of Psychology at Macquarie University, Australia 

“Chickens exist in stable social groups. They can recognize each other by their facial features. They have 24 distinct cries that communicate a wealth of information to one other, including separate alarm calls depending on whether a predator is traveling by land or sea. They are good at solving problems. ‘As a trick at conferences I sometimes list these attributes, without mentioning chickens, and people think I’m talking about monkeys,’ Mr. Evans said. 

Perhaps most persuasive is the chicken’s intriguing ability to understand that an object, when taken away and hidden, nevertheless continues to exist. This is beyond the capacity of small children.” 

Grimes W, “If Chickens Are So Smart, Why Aren’t They Eating Us?” New York Times, January 12, 2003.

Dr. Christine Nicol, Professor of Veterinary Science at Bristol University, England 

“‘They may be bird brains, but we need to redefine what we mean by bird brains,’ she told the British Association Festival of Science at Leicester University. ‘Chickens have shown us they can do things people didn’t think they could do. There are hidden depths to chickens, definitely.’” 

Ananova, “Chickens ‘Not Just Bird-Brains,’” September 11, 2002. http://www.ananova.com/news/story/sm_668673.html

Dr. Bernard Rollin, Professor of Animal Science at Colorado State University 

“Contrary to what one may hear from the industry, chickens are not mindless, simple automata but are complex behaviorally, do quite well in learning, show a rich social organization, and have a diverse repertoire of calls. Anyone who has kept barnyard chickens also recognizes their significant differences in personality.” 

Rollin B, Farm Animal Welfare: School, Bioethical, and Research Issues (Iowa State University Press, 1995, p. 118).
