Need something to get you through Monday? Here’s a pic of an adorable clutch of baby peregrine falcons on banding day at Cabrillo National Monument in California. At birth, peregrine chicks weigh about 1.5 ounces, but they grow quickly – they can double their weight in just six days. They reach nearly full size after only seven weeks. Cool fact about peregrine falcons: They are among the fastest birds, flying at up to 55 mph and diving at more than 200 mph when striking avian prey in mid-air. Photo by National Park Service.
I was reading about Vortices and after hours of research online, out of the blue I stumbled upon this amazing bird. This is the Red Necked Phalarope and from the looks of it seems to have put vortices to a really productive use - catching its prey.
By rotating around ~60-80 times a minute, it produces an upward vortex that sucks out insects/bugs/crustaceans from the water, which it swiftly picks up with its beak and eats. ( This one would have aced the Fluids class for sure :D)
This is analogous to tornadoes sweeping up cars and houses along its way in an upward swirl.
** The actual dynamics of vortices of course is waay more complicated. ;)
*** There are three species of phalarope (red-necked, red/grey, and Wilson’s), and they can all feed like that.
