Some species, including woodpeckers, have two egg teeth; one on both the upper and lower bill. [4] After time the egg tooth falls off or is absorbed into the growing chick's bill. [5] Some precocial species such as the kiwi, and superprecocial species including megapodes, do not require an egg tooth to assist them in hatching. They are strong ...
Motmots often move their tails back and forth in a wag-display that commonly draws attention to an otherwise hidden bird. Research indicates that motmots perform the wag-display when they detect predators (based on studies on turquoise-browed motmot ) and that the display is likely to communicate that the motmot is aware of the predator and is ...
When preening, a bird (such as this red lory) draws individual feathers through its beak, realigning and re-interlocking the barbules.. Preening is a maintenance behaviour found in birds that involves the use of the beak to position feathers, interlock feather barbules that have become separated, clean plumage, and keep ectoparasites in check.
Because of this, birds usually have a smaller number of bones than other terrestrial vertebrates. Birds also lack teeth or even a true jaw and instead have a beak, which is far more lightweight. The beaks of many baby birds have a projection called an egg tooth, which facilitates their exit from the amniotic egg. It falls off once the egg has ...

Granivorous (seed-eating) birds, for example, have ridges in their tomia, which help the bird to slice through a seed's outer hull. [20] Most falcons have a sharp projection along the upper mandible, with a corresponding notch on the lower mandible. They use this "tooth" to sever their prey's vertebrae fatally or to rip insects apart.
When it comes to getting their nails clipped, most dogs turn into big babies. There are some tips and tricks to make trimming dogs' nails at home a little bit easier, and less stressful for you ...
Female birds are able to produce more of a certain gender of birds that are more likely to survive under extreme conditions. In birds, the females' egg determines the gender of the offspring, not the male's sperm. In zebra finches, a study showed the effect of food on gender ratio production. For females, egg production is a metabolically ...
