Aspect Ratio Effects on the Aerodynamic Performance of a Biomimetic Hummingbird Wing in Flapping
Biomimetics, 2023 Hummingbirds are flapping winged creatures with unique flight mechanisms. Their flight pattern is more similar to insects than other birds. Because their flight pattern provides a large lift force at a very small scale, hummingbirds can remain hovering ...

Visual Sensory Signals Dominate Tactile Cues during Docked Feeding in Hummingbirds
Frontiers in Neuroscience, 2017 Animals living in and interacting with natural environments must monitor and respond to changing conditions and unpredictable situations. Using information from multiple sensory systems allows them to modify their behavior in response to their dynamic ...

Flight Mechanics and Control of Escape Manoeuvres in Hummingbirds. I. Flight Kinematics [PDF]
, 2016 Hummingbirds are nature’s masters of aerobatic manoeuvres. Previous research shows that hummingbirds and insects converged evolutionarily upon similar aerodynamic mechanisms and kinematics in hovering.

Floral resource availability of Dicliptera squarrosa (Acanthaceae) and its dependence on hummingbirds for fruit formation in a forest fragment of Central Brazil [PDF]
Plant Ecology and Evolution, 2019 Background and aims – Hummingbirds are dependent and specialized on nectar-feeding, and many plants depend upon them for pollination. However, the degree of plant-pollinator interdependence varies greatly among species; thus, information on plant mating ...

Resolution of a paradox: Hummingbird flight at high elevation does not come without a cost [PDF]
, 2004 Flight at high elevation is energetically demanding because of parallel reductions in air density and oxygen availability. The hovering flight of hummingbirds is one of the most energetically expensive forms of animal locomotion, but hummingbirds are ...

Current contrasting population trends among North American hummingbirds
Scientific Reports, 2021 As pollinators, hummingbirds play a critical role for both the function of ecological communities and in providing ecosystem services for people. To examine the conservation status of North American hummingbirds, we analyzed Breeding Bird Survey data for

Of hummingbirds and helicopters: Hovering costs, competitive ability, and foraging strategies [PDF]
, 2004 Wing morphology and flight kinematics profoundly influence foraging costs and the overall behavioral ecology of hummingbirds. By analogy with helicopters, previous energetic studies have applied the momentum theory of aircraft propellers to estimate ...

Colour preferences of UK garden birds at supplementary seed feeders [PDF]
, 2017 Supplementary feeding of garden birds generally has benefits for both bird populations and human wellbeing. Birds have excellent colour vision, and show preferences for food items of particular colours, but research into colour preferences associated ...
