I found this picture on Facebook:

Bald Eagle apparently flying upside-down

It definitely doesn't come from a particularly credible source (I F***ing Love Science), but I'm curious if that picture is genuine.

My mother claims that the legs, wings and head appear "unnaturally twisted" based on her past experience caring for Eagles and other raptors.

    I think you also need to define what you mean by "fly upside down". Being able to briefly invert oneself during flight and being able to achieve *sustained* inverted flight are very different things. – KutuluMike Dec 01 '14 at 13:44

    I wouldn't call *I Fucking Love Science* a not "particularly credible source". I think it's run by a single person, but I'm not aware of it promoting any bad information. It's perhaps not as reliable as some large organization, or certainly a peer reviewed journal, but big organizations don't always get it right. – David Conrad Dec 01 '14 at 17:50

    @DavidConrad I would. But in honestly it was a while ago since I blocked them when I finally got tired of seeing all the sensationalist click-baits they were pushing out in my feed. Probably just like this picture of an eagle flying upside-down. – Alex Dec 04 '14 at 09:51
  • @DavidConrad What I meant by that was that if someone were to use IFLS as a reference in an answer on this site, I'd just chuckle... but I'm a new user (this is my first question on skeptics as a matter of fact), so maybe that's unnecessarily strict...? – ApproachingDarknessFish Dec 07 '14 at 02:31

    @Approaching I didn't mean I'd use it as a reference, just that I wouldn't automatically discount something because it had appeared on IFLS. – David Conrad Dec 10 '14 at 18:33
  • I took the image and [flipped it over](https://i.stack.imgur.com/iqbrV.jpg). Apart from the eagle turning its head around at ~150 degrees (not unusual for birds) and sunlight coming onto the underside of its wings and on its chest... that looks like a perfectly normal image of an eagle, not at all "unnaturally twisted". –  Aug 31 '18 at 15:39

This image can be attributed to Pam Mullens a Canadian wildlife photographer sometimes going by the pseudonym EagleHunter.

This image and other photos of eagles flying in interesting and unusual poses can be found on the eagle page of her portfolio site.

I contacted Pam and she had this to say on the subject:

I can tell you this image is real and not doctored in anyway. I have spent many years with Eagles and this air flip is something they do when hunting, it's not flying upside down, it is a flip that happens in a matter of seconds.

It's definitely possible for an eagle to be upside down during flight.

Here's a Youtube video titled "Bald Eagle barrel roll". It shows some eagles playing or fighting or something and doing barrel1 rolls in the process. The picture you found could just be a well-timed photograph that happened during the middle of this eagle's roll.

Here's a gif showing a closer shot of a bird doing a roll mid-flight.

Do a barrel roll!

Here's one with bald eagles

Bald eagles dance

1. Might not technically be barrel rolls, but that doesn't really matter. You get the idea.

    it's technically not a [barrel roll](http://en.wikipedia.org/wiki/Barrel_roll) but I'll leave the pedantics aside – ratchet freak Dec 01 '14 at 11:34

    Note that "being upside down while in flight" may be a different matter from "flying upside down" as the querant intended the phrase to be taken... but I agree that this answers the "was the picture faked" part of the question. (And I suggest, as a compromise, that we all chill and just call it a "roll".) – keshlam Dec 01 '14 at 13:39

    @JohannesPille - Keep it friendly ;) I think you've latched on to a throwaway comment a bit too harshly. (Related comment now deleted - have dealt with 2 flags for rude/unconstructive behaviour) – Jamiec Dec 01 '14 at 15:28

    @ratchetfreak It makes me very happy that the See Also section of that page includes *Star Fox 64*. – KRyan Dec 02 '14 at 15:12

    Are you sure the birds in that gif are eagles? They look smaller. – RemcoGerlich Dec 03 '14 at 10:26
  • @RemcoGerlich Smaller compared to what ? The only visual reference is the text "MVNINN". – Tulains Córdova Dec 03 '14 at 14:12
  • @RemcoGerlich I don't know what kind of birds they are, actually. It doesn't really matter - the gif is just to supplement the video as the video doesn't let you see the details of what's going on. – Rob Watts Dec 03 '14 at 17:48

    @RemcoGerlich They're very clearly hawks. Or maybe handsaws. – Kyle Hale Dec 03 '14 at 21:31

    Judging from the dark [patagial marks](http://jerryliguori.blogspot.com/2013/09/red-tailed-hawk-patagial-marks.html) I'd say these are Red-tailed Hawks or a similar [buteo](http://en.wikipedia.org/wiki/Buteo). – JYelton Dec 04 '14 at 21:34
  • they're certainly no bald eagles - the coloring is wong – warren Dec 08 '14 at 14:52

This is a normal bird "thing". It's known as "whiffling":

Whiffling is a term used in ornithology to describe the behavior whereby a bird rapidily descends with a zig-zagging, side-slipping motion. Sometimes to whiffle, a bird flies briefly with its body turned upside down but with its neck and head twisted 180 degrees around in a normal position. ... This erratic motion resembles a falling leaf, and is used to avoid avian predators or may be used by geese (family Anatidae) to avoid a long, slow descent over an area where wildfowling is practised.[2]

I've seen it quite often, usually (in the case of our pond) when geese are coming in over high trees and want to lose altitude rapidly without gaining (much) airspeed. Apparently eagles do it for play/fighting (notice how the bird that rolls inverted sticks his legs up with talons extended). Kinda fun to watch.

The Goose flies upside-down article in the Belfast Telegraph has a photo of a goose doing it:
