Resumen
Durante los meses de Julio y Diciembre del 2010 se capturaron siete
microquirópteros nectarívoros a ambos lados de la cordillera de los
Andes en bosques nublados del Ecuador, cuatro Anoura caudifer y
tres Anoura geoffroyi, los cuales fueron sometidos a tres pruebas
distintas, primero para comprobar el aprendizaje de formas
geométricas, donde ninguna de las especies demostró
estadísticamente un aprendizaje significativo, otra prueba fue una
variación de ‘Delayed non matching for sample’, para observar la
curiosidad ante formas nuevas, donde se comprobó que acuden de
manera casi igual a la forma antes vista como a las nuevas y también
se analizó la preferencia entre texturas o formas de los objetos en la
búsqueda del alimento, donde se observó que se guían usando ambas
señales.
During the months of July and December of 2010 nectar feeding bats were captured on both sides of the Andes in Ecuador's cloud forest, four Anoura caudifer and three Anoura geoffroyi, were tested, first to check the Learning of geometric shapes, where none of the species showed statistically significant learning, another test was a variation of 'Delayed non matching for sample' to see the curiosity about new forms, which found that nearly the same way come to previously known form as the new ones and also analyzed the preference between textures or shapes of objects in search of food, where it was found that they use both signals.
