Which constraint does the avian wing's aspect ratio modulate during thermal soaring?

💡 Explanation

The higher aspect ratio of soaring bird wings minimizes induced drag because the induced drag is inversely proportional to the square of the aspect ratio of the wing. Therefore, soaring efficiency increases, rather than parasite drag rising under the same atmospheric conditions.
