Figure 2 from: Lanna LL, de Azevedo CS, Claudino RM, Oliveira R, Antonini Y (2017) Feeding behavior by hummingbirds (Aves: Trochilidae) in artificial food patches in an Atlantic Forest remnant in southeastern Brazil. Zoologia 34: 1-9. https://doi.org/10.3897/zoologia.34.e13228

Figure 2 - Positive correlation between the time spent feeding and the exhibition of aggressive behaviors by the hummingbirds. For this analysis, we included the time spent feeding by all hummingbird species in all sugar concentrations, and we summed the aggressive behaviors "expelling", "fighting", "frightening", "expel attempt", "alert" and "vocalizing".
