If we somehow remove pheromones, **do animals experience a phenomenon similar to human "visual beauty" when looking at members of the opposite sex?** For example, given a set of 20 female ducks observed through a glass panel, would male ducks attempt to court/mate with a small subset of female ducks first(more attractive ones), or is it based on some other criteria (most receptive, random, closest, fittest, pheromones, etc?)

If there is some "visual attractiveness selection criteria", **is there a requirement of certain complexity of the brain and/or visual system for an animal before this phenomenon starts to occur?** 

I'm aware of the existence of this question: [Why does sexual selection evolve beautiful features?](https://biology.stackexchange.com/questions/7568/why-does-sexual-selection-evolve-beautiful-features), and my question deals with the members of the same generation, not long-term evolution.
