Vivid birds do not initiate flight sooner despite their potential conspicuousness
The distance from an approaching threat at which animals initiate flight -flight-initiation distance (FID) -is a sensitive metric of variation in risk, but the effects on FID associated with the risk of possessing highly detectable external coloration are unknown. We tested whether variation in the degree of plumage vividness in birds explained variation in flight-initiation distance. After con...
متن کاملBirds do not work harder to breathe.
An efficient one-way airflow system is essential for bird flight. Extracting more oxygen per breath than mammals, birds can meet the costly fuel demands of flight. However, despite the gains achieved by maximising the amount of oxygen passing through their lungs, the metabolic cost of breathing for birds could be high. Birds were thought to have to work against the weight of their flight muscle...
متن کاملDeny dialysis or "D-NI" dialysis? The case for "do not initiate; do not ignore" orders.

متن کاملMarmots do not consistently use their left eye to respond to an approaching threat but those that did fled sooner
In many vertebrates, the brain’s right hemisphere which is connected to the left visual field specializes in the processing of information about threats while the left hemisphere which is connected to the right visual field specializes in the processing of information about conspecifics. This is referred to as hemispheric lateralization. But individuals that are too predictable in their respons...
متن کاملThe Flight of Birds
In a previous paper (Brown, 1948), the movements of the wing of a pigeon in slow flight were analysed. With the help of a new photographic technique further work on the flight movements at different forward velocities has been carried out. In this paper the analysis is extended with additional information obtained from normal cine-photography. Certain improvements and simplifications in the fla...
