Abstract Animal pollination is common among flowering plants. Increased morphological matching between floral and pollinator traits thought to increase pollen transfer feeding efficiency, but we lack studies that empirically demonstrate this. Working with Australian honeyeaters, find there positive correlation bill-corolla deposition at flowers, no how efficiently birds can extract nectar. The species the lowest deposited fewest grains had highest showing expectations were met on plant side of this interaction not side. Finally, different interspecific patterns scales a single flower visit versus landscape, due differences in visitation. This work illustrates need for more directly correlate trait fitness proxies plants avian pollinators.

A myriad of factors influence species interactions, and determining their relative importance is a major challenge in community ecology. Here, we explored the multiple influencing hummingbird visitation rates to flowers by considering pollinator floral traits alongside broader ecological context (i.e. phenology abundance). Our data were collected from 32 systematically surveyed sites within native vegetation across three distinct Neotropical bioregions, each characterized unique composition evolutionary histories. In total, sampled 6423 flowering individuals, representing 404 plant 68 species. At level, found that hummingbirds primarily visit with long, tubular corollas, aligning predictions pollination syndromes, also higher straight corollas. frequency was associated specific characteristics species, such as its bill length foraging behavior, where often forage on matching morphological traits. Further, our findings extended beyond expected trait preferences, revealing are outcome context; particularly, abundance conspecific, but not heterospecific, flowers. The effect conspecific varied suggesting perspective, intraspecific competition facilitation could prevail different regions. Additionally, whose morphology more other co‐flowering tended attract visits, only if they abundant enough stand out community. These highlight how traits, modulated context, jointly shape dynamics.
