A cancer syndrome or family cancer syndrome is a genetic disorder in which inherited genetic mutations in one or more genes predisposes the affected individuals to the development of cancers and may also cause the early onset of these cancers. Although cancer syndromes exhibit an increased risk of cancer, the risk varies.
Birds that swim, however, must contend with the increased buoyancy effects of having lighter bones and a reduced body mass. Instead, diving birds increase their muscle mass, resulting in an overall increase in body mass that reduces the effects of buoyancy and makes submersion easier.
In birds, some temperature control occurs in the respiratory system. [16] Water vapor heats cool air during inhalation in the trachea, and increases its humidity. [16] The resulting evaporative water loss varies greatly and depends on several factors including air sac pressure and the subsequent rate of air flow through the trachea.

Virtually all the raptorial birds sympatric in distribution with the blue jay may prey upon it, especially swift bird-hunting specialists such as the Accipiter hawks. Diverse predators may prey on jay eggs and young up to their fledgling stage, including tree squirrels , snakes , cats , crows , raccoons , opossums , other jays and possibly many ...
The noisy pitta is 19 to 21 cm (7.5–8.3 in) long. Males weigh 70–112 g (2.5–4.0 oz) and females 70–128 g (2.5–4.5 oz). [5] It is a colourful bird.

These birds are noisy and emit an incessant sound that sounds like ta-rik-tik, hence the name. Despite their noise they are difficult to find, being well camouflaged by the dense foliage . Diet is presumed to be similar to other hornbills namely fruit,seeds, insects and small mammals and reptiles.
