Whiffling Geese....a what?
Yes Grasshopper, there is such a thing as Whiffling Geese.
This is when Geese or Ducks suddenly flip upside down for a split second...so fast in fact that you may not even know it happened.
Today I witnessed a number of Geese coming in for a landing in strong winds and they performed this maneuver. Here are a few of them put into a single image.
The idea is for them to lose altitude so that they can land in a shorter distance.....like flying down...
Essentially, they are ringing their own necks! To take these images you have to look for a group of Geese coming in for a landing and if the wind is right you will see a number of them do a jerk in mid-flight. This jerk happens so fast that you can not see it with your eyes but a fast shutter speed on a camera can. To photograph...when you see some weird movements - hold down your shutter and let the camera do all the work. Doing this a few times will eventually turn up some inverted flying Geese.
