AMERICAN AVOCET
HABITS
Wherever this large, showy bird is found it is always much in evidence. Its large size and conspicuous colors could hardly be overlooked, even if it were shy and retiring; but its bold, aggressive manners force it upon our attention as soon as we approach its haunts. Localities and conditions best suited to its needs are still to be found in many places on the great plains and in the interior valleys of the far west. Its favorite resorts seem to be the shallow, muddy borders of alkaline lakes, wide open spaces of extensive marshes, where scanty vegetation gives but little concealment, or broad wet meadows splashed with shallow pools. If the muddy pools are covered with reeking scum, attracting myriads of flies, so much the better for feeding purposes. Dry, sun-baked mud flats or low, gravelly or sandy islands, with scanty vegetation, furnish the desired nesting conditions. In such open spaces they can be seen from afar and, long before we reach their haunts, the avocets are flying out to meet us, advertising the fact that we are approaching their home, making the air ring with their loud yelping notes of protest, circling about us and darting down at us in threatening plunges.
Courtship.—Prof. Julian S. Huxley (1925), who has made a study of the European species, says:
The avocet has no courtship. There are no songs or aerial displays; no posturing by the male; no mutual ceremonies; no special courtship notes. There is some hostility and fighting; a peculiar action by the female which is a symbol of readiness to pair, followed by an excited action on the part of the male; and a special post-paring action by both birds; but of courtship in any accepted sense none whatever.
However that may be, our bird does indulge in actions and posturings which look very much like courtship. On May 29, 1905, we spent some time in watching the avocets in a colony on an alkali flat covered with a sparse growth of short, curly grass, near Hay Lake in southwestern Saskatchewan. We could not find any nests there at that time and concluded that the birds had not laid. They were apparently still conducting their courtships, wading about gracefully in the shallow water, frequently bowing or crouching down close to the water; sometimes they danced about with wings widespread, tipping from side to side like a balancing tight-rope walker; occasionally one, perhaps a female in an attitude of invitation, would lie prostrate on the ground or water for a minute or more, with the head and neck extended and wings outstretched. Frequently they fooled us by squatting down on the ground, as if sitting on a nest; if we went to investigate, they would run away and repeat the act elsewhere; perhaps this act carried the suggestion of mating as a part of the courtship ceremony.
