Yellow rose-Nosed Vulture/Yellow rose herb

The yellow rose-nosed vulture is a sub-species of the savanna and desert vulture that has evolved to be able to live in plains and marshes. To do so, it has come to have a symbiotic relationship with two other groups of organisms.
Its nominal nose is shaped like a flower, which usually resembles a certain species of rose which lives nearby. This special rose doesn't flourish on bushes like others of its genre, but instead grows like grass and flourishes on the ground, hence its name "Yellow rose herb". Following this rose's example, the vulture makes a hole and uses its green-coloured wings to camouflage itself as a random patch of grass with a single flower in the middle which is, in fact, its nose.
This is where the second type of organism comes into play: hunter-type carnivorous beasts. Some beasts recognise the waiting vulture through a particularity we will explain later, and lies in wait nearby. Instead of attacking the vulture, they prefer to wait until another beast comes, attracted by the sight of what it thinks is a yellow rose. Since those roses are chock-full of nutrients, they often attract many a beast. But then, as they approach the vulture in disguise, they are ambushed by the predators waiting nearby. Once the predator has eaten its fill, it brings the remnants to the vulture in order for it not to move away.
With this, herbivorous beasts will avoid everything that looks like the yellow rose, until they forget and are once again drawn in by the tasty nutrients of the flower. Hence, a mutual relationship between the plant, the vulture and the predators is developed and if one of them evolves in a certain way in an area, the others will often follow suit.
Now the problem remains that insects would confuse the vulture and the flower. This is why both have developed infra-red patterns to signal their respective type to pollinating insects. As such, predators have also evolved to understand those signals. Sadly, herbivores have taken the cue. As such it is very frequent to see an increase in infrared seeing beasts in regions inhabited by yellow rose herbs and vultures.
