First Days - Harlequin Ducks

This ridiculously cute video of baby Harlequin Ducks (Histrionicus histrionicus) shows their first day outside the egg (about 20 hours old). Scientists at Patuxent Wildlife Research Center are training ducks to respond to sounds — just like a hearing test given to kids during elementary school — to learn more about their ability to hear underwater. This will inform the design of effective deterrents that warn ducks away from fisherman's nets and offshore construction.
