You will be pleased to hear that Charles Sturt University has agree to help set up a new website and we are hoping to transfer at least part of the information stored here to the new site. It will take a little time to get this organised, so please be patient.
Diamond arrives in the middle of the night after thunderstorms and soaking wet. Unfortunately, she misjudges her arrival, landing on the upper ledge and flipping upside-down, being unable to free herself for several seconds. She arrrives a bit later to dry off.
The reason for this is that many birds, especially raptors, have a perching reflex – where the toes lock onto a perch. If they flip upside down, it is difficult for them to relax their tendons to release them. The falcons often misjudge their landings at night, but I’ve never seen one latch on to the upper ledge before.
If you are interested in learning more about this locking mechanism, there is a short, interesting article with diagrams here: https://www.raptorresource.org/2021/01/22/racheting-raptor-toes-an-upside-down-eagle-at-great-spirit-bluff/
