The Morphology of Cross-Beaks and BMP4 Gene Expression in Huiyang Bearded Chickens
Animals, 2019 Bird beaks are important for biological purposes such as food intake, removing parasites, and defining phenotypic attributes. Cross-beaks are a threat to poultry health and are harmful to productivity, wasting some units in the poultry industry. However,

Cephalopods in marine predator diet assessments: why identifying upper and lower beaks is important
ICES Journal of Marine Science, 2011 Cephalopods are components of the diet of many predators worldwide. They are identified mainly using their chitinized upper and lower beaks, but because it has been assumed that the number of upper and lower beaks would be the same in predator diet ...

Antarctic octopod beaks as proxy for mercury concentrations in soft tissues
Marine Pollution Bulletin, 2020 As the role of mercury is poorly known in Southern Ocean biota, the total mercury (T-Hg) concentrations were evaluated in upper/lower beaks, digestive gland, gills and mantle muscle of Adelieledone polymorpha and Pareledone turqueti, two of the most ...

Skeletal Radiology, 1979
Hypertrophy of the talar beak is the product of traction of the insertion of the joint capsule. It is commonly seen in athletes and may be entirely asymptomatic despite its size. It should not be mistaken for spurring of the articular margin of the talus which is seen in tarsal coalition.

Behavioural consequences of partial beak amputation (beak trimming) in poultry
British Poultry Science, 19891. The effects of beak trimming on 16-week-old Brown Leghorn hens, housed individually in battery cages, was assessed by comparing their behaviour after trimming with their behaviour before trimming and with the behaviour of a sham-operated control group. 2. In the short-term, times spent feeding, drinking and preening decreased. 3.
