Does a flower's lack of scent turn away a hummingbird?

Yes, a flower's lack of scent can turn away a hummingbird, as these birds are often attracted to fragrant flowers. While visual cues, such as bright colors, are significant in attracting hummingbirds, scent also plays a role in their foraging behavior. Flowers that produce a sweet fragrance can signal to hummingbirds that they offer nectar, making them more appealing. However, some hummingbirds may still visit flowers without scent if they are visually attractive and abundant in nectar.
