Bird mortality due to collisions with wind turbines is one of the major ecological concerns
associated with wind farms. Data on the factors influencing collision risk and bird fatality are …

Many animals use vision to detect, discriminate, or recognize important objects such as prey,
predators, homes, or mates. These objects may differ in color and brightness—having …

Ultraviolet (UV) light occupies the spectral range of wavelengths slightly shorter than those
visible to humans. Because of its shorter wavelength, it is more energetic (and potentially …

Birds are renowned for their exceptional vision and the way that this enables them to survive
and navigate the world in such a unique way. However, it is now recognised that avian …

Color vision is essential for an animal's survival. It starts in the retina, where signals from
different photoreceptor types are locally compared by neural circuits. Mice, like most …

Ultraviolet (UV)-sensitive visual pigments are widespread in the animal kingdom but many
animals, for example primates, block UV light from reaching their retina by pigmented …

Animals are thought to use achromatic signals to detect small (or distant) objects and
chromatic signals for large (or nearby) objects. While the spatial resolution of the achromatic …

Convergent evolution is widely regarded as a signature of adaptation. However, testing the
adaptive consequences of convergent phenotypes is challenging, making it difficult to …

Seabirds, and particularly fledglings of burrow-nesting species, are greatly impacted by light
pollution. During their inaugural flights from colony to sea, fledglings become grounded after …

Visual signals are often under conflicting selection to be hidden from predators while being
conspicuous to mates and rivals. Here, we investigated whether 3 different island …
