The ecological co‐dependency between plants and hummingbirds is a classic example of a
mutualistic interaction: hummingbirds rely on floral nectar to fuel their rapid metabolisms …

Hummingbirds are the most specialised nectarivorous birds and show close ecological
relationships to their food plants. Their small body size, bright colors, and unique behaviour …

Specialization of species in interaction networks influences network stability and ecosystem
functioning. Spatial and temporal variation in resource availability may provide insight into …

Understanding the origin of biodiversity has been a major focus in evolutionary and
ecological biology for well over a century and several patterns and mechanisms have been …

Unambiguous examples of ecological causation of sexual dimorphism are rare, and the best
evidence involves sexual differences in trophic morphology. We show that moderate female …

As functional morphologists, we aim to connect structures, mechanisms, and emergent
higher-scale phenomena (eg, behavior), with the ulterior motive of addressing evolutionary …

Matches between the bills of hummingbirds and the flowers they visit have been interpreted
as examples of coadaptation and feeding specialization. Observations of birds feeding at …

Hummingbirds have two main foraging strategies: territoriality (defending a patch of flowers)
and traplining (foraging over routine circuits of isolated patches). Species are often classified …

The elongated tails adorning many male birds have traditionally been thought to degrade
flight performance by increasing body drag. However, aerodynamic interactions between the …

The seasonal movement of animals at broad spatial scales provides insight into life-history,
ecology and conservation. By combining high-resolution satellite-tagged data with …
