A new research has shown that the bird’s beak’s internal structure is complex and intended to help cool birds in warm climates. The scientists from the University of North Carolina Wilmington, Cornell University and the National Museum of Natural History gathered to make the research successful.
The scientists have said that birds’ beaks have developed in many ways for several different situations. They can dig deep in search of food and some can dig deep into flowers. The researchers said these different uses depend around the world. The team of scientists examined specimens from two Song Sparrow subspecies. Additionally the researchers took one sparrow from an area with little moisture and a warmer climate and the other from a cooler climate.
The scientists have claimed that there is a complex structure inside bird beaks. This structure moderates the temperature. The scientists have stated that in the larger surface area in warm climate, sparrows increased their beaks’ ability to cool air and recapture water.
