Although I first met the black-necked stilt in the Florida Keys in 1903, it was not until I visited the irrigated regions of the San Joaquin Valley in California in 1914, that I saw this curious bird living in abundance and flourishing in most congenial surroundings. It was a pleasant change from the cool, damp air of the coast region to the clear, dry warmth of this highly cultivated valley. The naturally arid plains between the distant mountain ranges had been transformed by irrigation into fertile fields of alfalfa and wheat, vast areas had been flooded with water from the melting snows of the Sierras, forming grazing lands for herds of cattle and endless marshes, wet meadows, ponds and creeks, for various species of water birds. As W. Leon Dawson (1923) puts it: The magic touch of water following its expected channels quickens an otherwise barren plain into a paradise of avian activities. Ducks of six or seven species frequent the deeper channels; coots and gallinules and pied-billed grebes crowd the sedgy margins of the ponds; herons, bitterns, ibises, and egrets, seven species of _Herodiones_, all told, occupy the reedy depths of the larger ponds or deploy over the grassy levels. Rails creak and titter, red wings clink, yellow-headed blackbirds gurgle, wrangle, and screech; while the marsh wrens, familiar spirits of the maze, sputter and chuckle over their quaint basketry. The tricolored blackbirds, also in great silent companies recruited from a hundred acres, charge into their nesting covert with a din of uncanny preoccupation. Over the open ponds black terns hover, and Forster terns flit with languid ease. The killdeer is not forgotten, nor the burrowing owl, whose home is in the higher knolls; but over all and above all and through all comes the clamor of the black-necked stilt and the American avocet. Of all these birds, the stilts were the most conspicuous in the wet meadows about Los Banos, where they were always noisy and aggressive. I have never seen them so abundant elsewhere, though I have seen them in similar situations in Florida and Texas, on extensive wet meadows where shallow water fills the hollows between myriads of little muddy islets and tufts of grass. Here they can wade about and feed in the water or build their nests on the hummocks above high-water mark, and here their young can hide successfully among the grassy tufts.
