Sword-billed Hummingbird
The sword-billed hummingbird possesses one of the most extraordinary beak-to-body ratios in the avian world. Its bill is longer than its body, a remarkable adaptation for accessing nectar from long, tubular flowers. This specialization allows the hummingbird to reach deep into flowers that other hummingbirds cannot access, giving it a unique ecological niche.
