Yes, green hermit hummingbirds (Phaethornis guy) do play a role in pollination. Hummingbirds, including the green hermit, are known to be effective pollinators of various plant species, particularly those with tubular flowers.
As they feed on nectar, hummingbirds inadvertently transfer pollen from the stamen (male reproductive organ) of one flower to the stigma (female reproductive organ) of another flower. This pollination process enables plants to reproduce and produce seeds, ensuring their survival and genetic diversity.
Green hermit hummingbirds, like other hummingbird species, have long, curved beaks that are adapted for accessing the nectar deep within tubular flowers. As they insert their beaks into the flower, their heads and bodies come into contact with the flower's reproductive structures, facilitating pollen transfer between flowers.
While specific plant species rely on particular pollinators, green hermit hummingbirds are known to pollinate various plants, including those with red or orange tubular flowers that are well-suited for their feeding habits.
Hope this is helpful :)
