The human eye contains three types of cone cells, photoreceptors that allow us to see blue, green and red light. Many animals have different combinations of photoreceptors, which means that they ...

Birding: Putting a new perspective on bird’s-eye views The ability of birds to distinguish color far surpasses human ability. The density of the cones in the retina of a bird is two to three ...

An analysis of the 120-million-year-old bird revealed that the creature's eye tissues — more specially, its rods and cones — had fossilized in remarkable condition. (Whereas rods sense grey ...

Scientists have discovered a fossilized fish so well preserved that the rods and cones in its 300-million-year-old eyeballs are still visible under a scanning electron microscope.

While humans have three color cones in the retina sensitive to red, green and blue light, birds have a fourth color cone that can detect ultraviolet light. A research team trained wild ...

For now the construction group are trialling heavier road cones to keep the keas safe and deter them from playing in traffic; something a nationally endangered species probably shouldn't be doing.

Hyperuniformity gives birds the best of both worlds: Five cone types, arranged in near-uniform mosaics, provide phenomenal color resolution. But it’s a “hidden order that you really can’t detect with ...

Cheeky rare bird moves traffic cones around, tricking dumb humans Meet the most adorable, and sadly endangered, tricksters around.
