Bird wave lengths
WebDec 5, 2011 · Most birds are able to see wavelengths over a long range, many times reaching past the visible light range into the ultra-violet light range. It is thought that birds are also able to see polarized light and use … Many species can see light within frequencies outside the human "visible spectrum". Bees and many other insects can detect ultraviolet light, which helps them find nectar in flowers. Plant species that depend on insect pollination may owe reproductive success to their appearance in ultraviolet light rather than how colorful they appear to humans. Birds, too, can see into the ultraviolet (300–400 nm), and some have sex-dependent markings on their plumage that are vis…
