Additionally, I would like to know how the feeding behaviors of each species differs--the duration of feeding times, visitation frequency, if individuals will defend these resources, andwhether these behaviors correlate with different traits of each plant. Tamm and Gass (1986)found that hummingbirds prefer the highest nectar concentration when given the choice withartificial feeders. Thus, I predict that hummingbirds will visit B. solanoides individuals thatproduce the most concentrated nectar with the highest frequency, and that I will see the mostterritorial interactions protecting the plants with more concentrated nectar. However, I alsopredict that plants with greater numbers of flowers will attract a higher frequency of visits, andthat this may prove a more important criteria for hummingbirds than nectar concentration, due tothe frequency at which hummingbirds must feed. Further, in this study I will investigate interandintraspecific interactions among hummingbirds, to determine if hummingbirds will defendresources from other species as well as their own. I predict that the generalist species will in factexhibit territorial behavior towards individuals of other species, as well as members of their own
