Abstract: Plant–animal mutualistic interactions through ecological network systems and the environmental conditions in which they occur, allow us to understand patterns of species composition structure dynamics communities. We evaluated whether flower morphologies with different pollination syndromes (ornithophilous non-ornithophilous) are used by hummingbirds these characteristics affect (core-peripheral species) hummingbird networks. Observations were made flowering patches, where plant–hummingbird recorded at three altitudes (300–2500 m) during seasons (dry, rainy post-rainy) from 2015 2016 El Triunfo Biosphere Reserve, Chiapas, Mexico. 15 interacting 58 plant species, greatest number (11; 14) (28; 40) found middle dry season, respectively. In all study sites, most visited had an ornithophilous syndrome (67%) high (22 season (26 species), but more individual non-ornithophilous species. The exhibited level specialization towards plants (H2′ = 0.74), networks plant-hummingbird generalist 0.25); i.e. visiting both syndromes, low altitudes. core remained constant altitude varied between according phenology
