Delivery time: 8-12 business days (International)
Las formacin de grupos en las aves es una estrategia eficaz para incrementar las probabilidades de sobrevivencia ante el ataque de los depredadores. En un grupo de aves, cada par de ojos incrementa el rea que puede ser vigilada, haciendo ms oportunos los llamados de alarma, adems, el escape en grupo dificulta al depredador focalizar a una presa. En el Altiplano Mexicano ocurren un gran nmero de especies residentes y migratorias que forman grupos estacionales. El gorrin de Worthen es una especie endmica de Mxico, poco estudiada y que juega un papel importante en la dinmica de la comunidad de aves de pastizalmatorral. Aqu presentamos los resultados sobre una investigacin del uso que sta ave hace de su hbitat y de cmo se relaciona con otros pjaros. Encontramos que la composicin especfica del grupo y el nmero de individuos por especie en cada grupo determina el papel que cada taxn juega como lder o subordinado, adems de que en grupos multiespecie la eficiencia de forrajeo es mayor. Aparentemente para las especies migratorias la experiencia y conocimiento del hbitat de residentes como el gorrin de Worthen facilita y hace ms eficiente la bsqueda de alimento.
