There are few reliable sources on this, but some people have estimated that a bombastic macaw has the sting strength of 500 to 700 pounds per square edge, which is close to that of a large frank bite. Just watching a boastfully macaw or cockatoo crush a Brazil nut, rip a 2-by-4 into shreds or break a weld on metallic cage bars convinces most observers that a bird ’ second beak is herculean and not to be messed with .
Factors that Contribute to Bird Beak and Bite Power
Of run, the smaller the beak, the lighter the bite .
“ It is the beak size — not the dame size — that counts, ” said Gayle Soucek, a favored deal adviser in Illinois and author of Doves : A Complete Pet Owner ’ s Manual ( Barron ’ randomness, February 2006 ).

For exercise, a cockateel might weigh about the lapp as a Senegal, but the Senegal has a much larger peck and a a lot stronger bite .
That doesn ’ metric ton completely mean a bite from a smaller beak can not cause trouble. In my have, birds with smaller beaks tend to use them more precisely, with better bearing. They seem to find the more narrow, crank places like the cuticles. In my experience, they will besides more likely react by grinding the tissue without letting go rather than a sting and spill .
The bird ’ s degree of “ bite inhibition ” is besides a agent .
“ Some birds, such as hyacinth macaw, have highly powerful biting exponent, but they are docile and will rarely bite at full persuasiveness, tied when frightened, ” Soucek said. “ other birds, such as hormonal Amazons, have next to no bite inhibition and will give it all they ’ ve got and aim for maximum damage. ”
In his ledger “ King Solomon ’ s Ring, ” naturalist Konrad Lorenz discusses how animals with firm “ weapons ” tend to use them more gently and cautiously with interactions with their own species, than the animals with less strong weapons. This may be the reason why birds with stronger beaks may use them more cautiously, if that dame views humans as separate of their social structure. If a shuttlecock truly felt that it was in danger ( for example, it was trying to protect a nest site from an invader as with a hormonal parrot ), it would be more likely to use every tool at its disposal to get away. It would use the beak power that it has .
It has been written that some parrots use their beaks differently even when it comes to gender. Female budgies, I have found, tend to bite difficult, and this could be explained by their need to potent yack muscles to prepare the nest cavity more so than the males who are less ‘ in blame ’ of nest hole dig and homework .
Another agent is the biomechanics of the beak structure .
“ The across-the-board, more shovel-like the lower beak, the more mechanical imperativeness the bird has, and the harder it can bite. The narrower the beak, the less mechanical pull the bird has and the less imperativeness to its bite, ” Nemetz said .
That is why a canary or toucan—both of which have narrow upper and lower beaks that occlude about evenly—are not physically able to put a much press into their bites as an Amazon or macaw. This is not to say, however, that a softbill boo, such as a toucan, can not inflict pain.
“ Toucans are more than capable of breaking skin. They may not have the mechanical advantage that parrots have, but they do have very shrill, serrate beaks, ” Nemetz said .
Parrots are thought to be related phylogenetically with raptors, which could explain why their peck arch around in a hook and it is so gear to destruction of things in the environment. The hook bill is one of the most recognizable view of the parrot ( “ psittacine ” ) group .
many cockatoos have a lower beak with two luff tips on either side of the stop consonant ( contact ) come on which seem to enhance the ability of the bird to rip and rag things. In my have, cockatoo bites tend to be the most deleterious and in fact, have led to stitches on occasion .
Some parrots have a beak with a longer, needle-like upper bill than others. Examples include slender billed cockatoos and to a minor academic degree, many amobarbital sodium crowned conures. These long needle-like projections can besides enhance their bite ability to pierce through bark and to get deep into nuts .
Most if not all birds have some degree of movement of the upper bill in conjunction with the skull. In general, this effect is called cranial kinesis and in general ; mammals do not have it. Our parrot species have one of the most advance versions of this called prokinesis. This means that the upper poster moves via a joint between the upper jaw bone and the stay of the skull. The lower beak, the lower jaw, is besides connected with multiple joints with the bones of the skull. due to this complex connection, it besides moves more than precisely a “ up and down ” motion—it can make the lower beak edge ( called the mandibular “ tomia ” ) move side to side and from front to back. This run mobility gives the parrot exquisite control in placement and pressure using the bill .
Of course, bones don ’ metric ton move without muscles. There are strong muscles that are between the bills and the skull to move the different parts around. One of the most important group of muscles are those within and that control the fleshy, mobile parrot tongue. many birds—including finches, canaries, mynahs, toucans and doves—have relatively small constrict tongues that have minimal apparent motion other than front man and back and a little snatch of raise. Parrots have a much compact, muscular structure tongue that has a certain academic degree of tractability and about prehensile aspect to it. Parrots can use their tongue to position what is being bitten in order to deliver the impel to the optimum part .
The bones are covered with a thick keratin covering called the rhamphotheca. The upper bill ’ second share is called the rhinotheca, and the lower bill ’ sulfur part is called the gnathotheca. The shape of this cover is what gives the beak the astute edges .
One final examination expression of bird beaks that can enhance the bird ’ s ability to use it precisely and powerfully involves the sensitive nerves that they have in the beak. I find that many people don ’ thyroxine understand how sensible their birds ’ beaks are. There are nerves through the beak specially at the edges. They are called Herbst corpuscles and if you look at the edges of your bird ’ s peck cautiously, you can see short spots in a rowing at the beak ends. These are the passageways of the nerves. This gives the dame sensation to know more about what they are touching with the beak, to understand the coerce points best to push on .
Helping Your Pet Bird Put His Beak to Work
Our parrots have a natural leaning to destruct many things in our environment. In order to help our pet birds exert their normal behavior, you have to give them many natural shuttlecock toys to destroy. There are a broad variety to choose from, with many textures, shapes, materials and colors.
A great region of understanding your parrot involves understanding how it uses its bill. Your bird learns about and manipulates much of its environment via the beak, in some ways like to the way we use our fingertips and hands. Your parrot can sense the gentle affect of a beak massage or tear apart a big branch. Your parrot will never let you take this amaze structure for granted .
