Animals gather information about their surroundings, including their social environment, using a wide range of sensory modalities. Variation in reception, processing and interpretation of information (cues or signals) can lead to differences in how individuals perceive their local environment. Yet, how individual differences in environmental perception

Multi-camera Realtime 3D Tracking of Multiple Flying Animals [PDF]
Automated tracking of animal movement allows analyses that would not otherwise be possible by providing great quantities of data. The additional capability of tracking in realtime - with minimal latency - opens up the experimental possibility of ...

Adult Greater Flamingos showed no significant sexual dimorphism in beak shape in either dorsal or lateral view. Geometric morphometric analyses revealed broad overlap between sexes, while dorsal beak shape displayed a significant size‐related allometric component.

Treating hummingbirds as feathered bees : a case of ethological cross-pollination [PDF]
Hummingbirds feed from hundreds of flowers every day. The properties of these flowers provide these birds with a wealth of information about colour, space and time to guide how they forage.

Read the free Plain Language Summary for this article on the Journal blog. Abstract The dependence on biotic pollination may constrain plant phenological responses because flowering time ultimately defines reproductive success. We proposed a local‐scale study combining long‐term phenology and experimental data to evaluate how a key functional trait—the

Foraging plasticity and physiological adaptations enable hummingbirds to subsist on dilute nectars
Read the free Plain Language Summary for this article on the Journal blog. Abstract Hummingbirds frequently feed on small volumes (<30 μL) of sucrose‐rich nectars. Climate change is expected to affect both the abundance and the concentrations of accumulated nectar.

Effect of artificial feeders on pollen loads of the hummingbirds of Cerro de La Muerte, Costa Rica
Although sugar-water feeders are commonly used by enthusiasts to attract hummingbirds, little is known about how they affect hummingbird behavior and flower use.

On traits matching and the modular organization of food web and occurrence networks
What mechanisms shape ecological networks? In Paraná River piscivores, species traits and abundance scaling promote modular structures. Our findings reveal how communities self‐organize and highlight the conditions needed to sustain them. Abstract Modularity and nestedness have been observed recurrently across different ecological networks, including ...

Fall Field Report, August–November 2015 [PDF]
To start, a housekeeping item: in the species accounts that follow, whenever I use the term migrant I am referring to fall migration only. Many species, of course, have differing migration strategies and timing in spring and fall. Much of the data used

The Red Queen unveils the sexual and mating strategies of flowers
Although the conventional wisdom is that floral traits of plants evolved in concert with their mutualistic pollinators, here we showed that several key sexual and mating traits of plants, which modulate their outcrossing strategy, evolved in response to the pressure exerted by their antagonistic insect herbivores.
