Their anatomy allows such postures, they are not too stupid to grok aerodynamics (the avian brain is arguably the single best technology on Earth to do this kind of aerodynamic calculations), they do it when it is appropriate. It does not play a major or even very significant role in their flying, because small perchers are optimized in a different direction.

Off topic. Ginny (Robert's widow) loved to see examples of the words he introduced to the language show up in every day useage. I wish she were still with us so I could send this one to her. I miss Ginny.

On topic. Having a brain capable of grokking aerodynamics doesn't mean that they go about it in the same way that we do. For example, migrating swans generally don't adjust for crosswinds during their flights. They tend to fly the no-wind heading for a radius about equal to the expected distance between origin and destination, then turn transversely to intersect their destination. A very inefficient way of doing it.
