Here’s some cute to end the week: A baby spotted #owl bobbing its head. Ever wonder why they do this? Since owls cannot move their eyes inside their head, they must swivel their heads to change their field of vision. While it might look like dancing, this movement (called parallaxing) helps owls build a better picture of their surroundings. ? Video by Steven Sobieszczyk, @usgs.
