I am convinced myself that the dance of three peewits, as described by Mr. Hudson in The Naturalist in La Plata, has had some such origin as this. What one wants, in order to arrive at the real nature of the latter, is a number of detailed descriptions, instead of a mere general one, never in my opinion of much value in such matters. Pains, also, should be taken to ascertain the sexes of each of the three birds that takes a part in the show.
Another nuptial sport or play which these birds indulge in belongs to air—where, indeed, they pipe as strongly and easily as upon the ground. This that I speak of, however, appeals in an equal degree to the eye and ear. Two birds pursue each other closely, mounting all the while in a steep slant, till, having gained some elevation, both turn at an acute angle, and descend in the same manner, in a reversed direction, thus tracing the shape of a pyramid. Having completed the air-drawn figure, they immediately reproduce it, and thus they continue on quickly vibrating wings—now upwards, far above the cliff-line, now downwards, almost to the sea—piping the whole time in the fullest-throated way. Even in a small and sober-suited bird such a performance might attract attention. How much more here where, to the boot of the large size of the two artistes, and the noise they make, the boldly contrasted black and white of their plumage, the deep rose-red of the bill, and pale rose-pink of the legs, give it a very lovely appearance. For myself, I have seen few things more striking.
