  • Bird of the Month: Peregrine Falcon January 2019

      Peregrine Falcon By Russ Chappell The word “peregrine” means “wanderer” or “pilgrim,” and Peregrine Falcons reside world-wide. Thanks to captive breeding and a 1972 ban on DDT, this species has risen from near extinction in the 20th century to now populate every continent except Antarctica. The United States-Canada Stewardship rates peregrines as 10 out of 20 on the Continental Concern Score, but it is no longer on the State of North America’s Birds Watch List. However, their breeding areas, especially in the Prescott area, are monitored and protected during certain times of the year, and you should check with the Prescott National Forest Service before entering a Peregrine Falcon breeding area to avoid issues. Considered the fastest animal on earth, at least in a dive or “stoop” the Peregrine Falcon is capable of speeds of over 200 MPH, able to withstand 18G, and possesses exceptional vision which is protected by special membranes at high speed. They are capable of bringing down prey twice their size with their powerful talons and a unique beak. Adaptable to almost any habitat some Peregrines migrate over 15,000 miles a year, while other choose to call a selected region home year-round. In coastal areas nests are usually built on cliffs in “eyries” however being extremely adaptable many reside in cities with high skyscrapers that provide both elevation and a variety of birds to hunt

  • Ask a Rocket Scientist: Skybound: Looking (up) at nature, nurture, & mimicry

    By Prof. Werner Von Karmann Dear Prof. Von Karmann, Does anything in nature fly the same way as airplanes, helicopters, or rockets? — Michael D., Chino Valley Mike, thanks for your question. Over the millennia, humanity has watched nature for inspiration. Today, we call it biomimicry, which is a fancy word for observing the nature around us and adopting what one observes into a machines we build or applying that observation to the mathematics or physics used to design a machine. In Western folklore, we have the story of Icarus. Long story short: Dude made wings to fly like a bird. Not a happy ending to that one. You gotta know the limits of the knowledge extracted from nature when you apply it to manmade devices. Like don’t fly too close to the sun or your wings will melt. When it comes to flying, you can go for endurance (long flight) or attack (fast and agile maneuvers). In nature, you can see how animals evolved to conserve energy for endurance, as visible in pelagic birds and fish, and for those fast attack maneuvers in raptors, such as Peregrine Falcons. For endurance, you have to minimize expended energy. When it comes to a vehicle, bird, or fish moving through air or water, the force that provides the vertical force for flight or horizontal force to push it along is called lift
