“Beakiation” is a newly coined word to describe how birds in the wild use their beaks to move from tree to tree–similar to how monkeys do with their limbs.
A recent 2024 study was launched by the New York Institute of Technology (NYIT), with work done by Edwin Dickinson, Melody W. Young, and Michael C Granatosky. The study involved four rosy-faced lovebirds. A runway was set up to give the birds a space to move about as they pleased. The purpose was to watch how the birds used their beaks to facilitate movement. The birds performed admirably by often using their beaks to grasp a tree limb while releasing their feet from support surfaces. They moved across spaces by grasping with their beak and “swinging” to the next location.
Faster Movement in Dense Spaces
The reasoning behind this behavioral pattern is that it enables faster movement in tree-dense areas. Flight involves a set of motor movements that require more energy than swinging requires. It also helps birds move faster than ground-based predators, much like monkeys do to evade their predators.
Birds’ beaks are amazingly strong, with a grip that can hold many times the bird’s weight. The upper beak has a hinge between the bill and the skull that allows the bird to amply flex that region. This becomes helpful – much like an extra hand – when grasping a branch to allow the bird to pull itself up. The upper beak is used as a propelling force to give the bird extra power in movement and lift. Taking nothing away from the power of the lower beak, it is clear that each part operates independently of the other to achieve great physical feats.
In the wild, using their beaks to travel more effectively helps parrots avoid ground travel, where predators might lurk. They can do as the monkeys do to get from place to place.
