What do cows mean when they moo?
Scientists in England have been eavesdropping on “conversations” between cows and their calves to answer that question–and they’ve discovered that moos convey a lot more meaning than you ever imagined.
“This is the first time that complex cattle calls have been analyzed using the latest and best techniques,” Dr. Alan McElligott, a senior lecturer at Queen Mary University of London and the co-author of a new study about moos, said in a written statement. “Our results provide an excellent foundation for investigating vocal indicators of cattle welfare.”
The scientists spent 10 months digitally recording call sounds from two herds of free-range cattle on a farm in Radcliffe-on-Trent, Nottinghamshire. The researchers then spent several months performing the acoustic and statistical analysis of the data. They determined that mother cows use two types of contact calls with their calves: a quiet low-frequency call when the calf is nearby and a loud high-frequency call when the calf is far away. Calves produce one type of contact call when they’re separated from their mothers and they want to nurse.
