Brush-tipped tongue: Many nectar-feeding animals have tongues that are tipped with tiny, hair-like structures called papillae. These papillae help to collect and hold onto nectar and pollen.
Proboscis: Some animals, such as butterflies and moths, have a long, tubular mouthpart called a proboscis. The proboscis is used to suck up nectar from flowers.
Specialized beak: Some birds, such as hummingbirds and sunbirds, have long, slender beaks that are perfect for reaching into flowers to access their nectar.
Co-evolution: Nectar-feeding animals and plants have coevolved over time. As plants produce new flower shapes and sizes, nectars-feeders have developed adaptations to access them. The result is a complex and ever-changing interaction between the two groups of organisms.
