The "eagle" mentioned here is described as stirring up the nest, supposedly to teach the young eagles to fly. However, I'm having difficulty finding a documentary of an eagle species that behaves this way. According to some quick search on eagle documentary (see [this interesting documentary about white-tailed eagles](https://www.youtube.com/watch?v=Fx1-Os0l7Ac)), the young eagles don't learn to fly by getting pushed (as described in [this motivational video](https://www.youtube.com/watch?v=_ap8u-xD8xc)), but they learned flying by practicing their wings on good winds, so I started to find more resources to find out the species of the eagle depicted here.

Some commentaries (see MacLaren's Exposition in [this website](http://biblehub.com/commentaries/deuteronomy/32-11.htm), read the part starting with the headings "I. Here is a great thought about God") suggest that it might be "the carnivorous vulture". However I was having a difficulty finding documentaries about the fledgling process of vultures (consider [this](http://en.wikipedia.org/wiki/Turkey_vulture) and [this](http://en.wikipedia.org/wiki/Bearded_vulture)).

After reading more about this passage, I found someone had posted a devotional specific for this passage on aptly-named website [eagleflight.org](http://www.eagleflight.org/cyberstudies/actions-and-attitudes-of-a-growing-church/157-with-eagles-wings). It connects the reference to "eagle" here to the one mentioned in Job 39:27-28:

> 
> 27] "Does the eagle soar at your command and build his nest on high? 28] He dwells on a cliff and stays there at night; a rocky crag is his stronghold. 29] From there he seeks out his food; his eyes detect it from afar. (It’s in the nest.) 30] His young ones feast on blood...

It also describes the process mentioned in Deut 32:11 in more depth, supposedly from the author's experience in bird-watching:

> 
> All at once she pushes the little one out of the nest, and the eaglet falls down the face of the cliff, surely to be destroyed. But not so! In a flash the great mother eagle flies down, catches the little one on her back, and flies up and deposits it in the nest. ("Whew! Mom, that must have been an accident.") But it wasn’t an accident. The mother bird pushes the little one out again, and again, over and over.
>

From there I started looking on eagles which build their nest in the rocks (the white-tailed eagle that I found at the top of this page don't build their nests in the rocks) and found this Wikipedia page on [Golden Eagle](http://en.wikipedia.org/wiki/Golden_eagle). There is even a reference to this verse over there (see this [line](http://en.wikipedia.org/wiki/Golden_eagle#cite_ref-203)).

However, the part of that Wikipedia that describes the [fledgling](http://en.wikipedia.org/wiki/Golden_eagle#Fledging_and_ensuing_years) doesn't say the parent eagles stir the nests to teach the young eagles to fly. That section does mention the first flight being abrupt, though:

> 
> The first attempted flight departure can be abrupt, with the young jumping off and using a series of short, stiff wing-beats to glide downward or being blown out of nest while wing-flapping. The initial flight often includes a short flight on unsteady wings followed by an uncontrolled landing.
> 
> 
> 

My question is, then: **is the golden eagle really the species being depicted in this passage? If not, then which one?**

And I am also interested in seeing a documentary, if available, of the fledgling process of the eagles. Not necessarily a video, although that would be best, but I'm looking for a more scientific (that is, empirical) source of the behaviour of the eagles. I think this aspect would already be part of any work of an answer, but just to make sure that it's there. =)

Note: I do really want to know the species depicted as I'm planning to draw an illustration of this passage, and I want to draw the correct bird =)
