more long-beaked hummingbirds

more short-beaked hummingbirds

Answer 1

more long-beaked hummingbirds. This is because the long, bell-shaped flowers are adapted to be pollinated by long-beaked hummingbirds. Therefore, these birds are more likely to have a higher population in this ecosystem as they are the most efficient pollinators for these flowers. The short-beaked hummingbirds may still exist in the ecosystem, but they may not be as abundant or as successful in pollinating the flowers.
