Quails Have Amazing Camouflage Skills to Protect Eggs
A recent study published in the journal Current Biology has hinted that quail have got expertise in camouflage. Conducted by researchers from the University of Nebraska-Lincoln, the review has claimed that mother quails have the skills to be familiar with their own eggs' patterning.
It is being said that quails lay their eggs at such places that they remain safe from predators. The ground-dwelling quail lays egg on a substrate so that the natural camouflage of the eggs maximize.
This maximization has been found to appear specific to individual birds. The report finds that Japanese quails are nesting birds, which build strong and robust nests on the ground. These birds tend to camouflage under vegetation.
Also, their maturity comes at the age of six weeks and these become able to produce by the age of 50 days usually. Female quail were given a choice to lay their eggs between four different backgrounds in the lab.
It was noted that a majority of these chose such background colours that could match their eggs' spots. Quail whose eggs had little pattern chose lighter surfaces. The strategy has been named as disruptive coloration as it includes contrasting patterns on surfaces making an object outline.
