Pleeeeez....Enviro folks capture animals and do all kinds of sh** to them....and for no real reason.
Remember the scientists who put wing tags on penguins and that colony suffered more attrition than others as a result- while they don’t fly, lenguins need silent wings as flippers underwater to catch prey and avoid predators with incredible hearing. When you live life on the edge in Antarctica that slight alteration making you noisier can have a big impact.
