“…Overall, resource partitioning among hummingbirds has been explained by different mechanisms related to differences in the use of nectar (Justino, Maruyama, & Oliveira, 2012;Lyon, 1976), which include variation in foraging behavior (Feinsinger & Colwell, 1978;Lara, Lumbreras, & González, 2009;Sandlin, 2000;Stiles, 1985), population movements at the landscape scale following the phenology of their plants (Buzato, Sazima, & Sazima, 2000;Des Granges, 1979;Ortiz-Pulido & Vargas-Licona, 2008), microhabitat differences (Kodric- Brown, Brown, Byers, & Gori, 1984;Ritchie, 2002), spatiotemporal segregation in resource use (Lara, 2006;Lara et al, 2011;Ornelas et al, 2002), and phylogenetic distance between species (Márquez-Luna et al, 2018;Martin & Ghalambor, 2014). Likewise, it has been proposed that interspecific morphological variations in traits, such as body size and bill length and curvature, play an important role in this resource partitioning (Bribiesca, Herrera-Alsina, Ruiz-Sánchez, Sánchez-González, & Schondube, 2019;López-Segoviano, Bribiesca, & Arizmend, 2018;Lyon, 1976;Maglianesi, Bohning-Gaese, & Schleuning, 2015;Rodríguez-Flores & Stiles, 2005;Snow & Snow, 1980;Stiles, 1975).…”
