Traplining hummingbirds have been observed to change their foraging behavior in response to a change in resource availability. Generally, trapliners change to territorial behavior when presented with an economically defendable resource. I investigated the degree to which aggressive behavior increases by observing changes in behavior frequency in response to increased resources. I observed that trapliner species showed an increase in aggressive behavior and a decrease in the total frequency of traplining behavior following the introduction of increased resources. My study also supports that traplining hummingbirds could switch their foraging behavior to territoriality when resources become economically defendable. Se han observado a los colibríes que cambian su conducta de alimentación como respuesta al cambio de la existencia de recursos. En general, los ermitaños cambian su conducta al territorialismo cuando tienen un recurso que vale la pena defender. Yo investigué el aumento de conducta agresiva al observar los cambios en la frecuencia de conducta antes y después de aumentar los recursos.
