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 2010 they reported seven Microchiroptera nectar on both sides of the range of the Andean cloud forests of Ecuador in four Anoura caudifer and three Anoura geoffroyi, which were subjected to three tests different first to check learning ways geometric, where none of the species showed statistically significant learning, another test was a variation of 'Delayed non matching for sample', to observe the curiosity about new ways, which was found to come from almost equal to the shape before the new view as well preferably analyzed the textures or shapes of objects in the foraging, which was observed to be guided using both signals.
