“…A very good example is the woodpecker, as shown in Figure 17. When the woodpecker strikes an object with its beak, the immense force at the tip is cushioned by its beak structure and the resilient hyoid bone [255,256]. Consequently, the impact's stress is significantly diminished from the beak's tip to where it connects with the skull, reducing the force that reaches the bird's cranium.…”

“…One of the emerging biomimetic technologies that claims to replicate the woodpecker's mechanism is known as the 'Q-collar' (https://q30.com/), a collar worn around the neck which serves to compress the jugular veins. Although based on the erroneous understanding of how woodpeckers actually avoid cranial damage [61,62], the 'Q-collar' is seen as a 'revolutionary approach to protecting the brain […] by mimicking the natural defense used by woodpeckers' [63] and has captured a significant amount of attention from the media, sports industry and scientific community [59]. What is often unmentioned is that getting the 'Q-collar' to the market, and testing its safety, required the sacrifice of a substantial number of experimental animals, first rats [64], then pigs [65], which all suffered experimentally-induced brain trauma while fitted with collars.…”

“…Excavating nesting hollows in trees is a specialized behaviour that is a particularly demanding task because it requires the bill to withstand a range of compressive and shearing mechanical stresses in order to avoid structural failure [9]. Consequently, cavity-excavating birds such as woodpeckers possess a suite of morphological and anatomical features that putatively improve their resistance to stresses experienced during cavity excavation [9][10][11][12][13]. However, the role of bill geometry in dissipating excavation stresses still remains poorly understood, which necessitates a comparative analysis of excavation performance across a range of bill shapes.…”
