reflect the trend suggested by M. A. Howe and B. A. Harrington (pers. comm.). Migrant shorebird populations have been monitored at Arlington, Texas, since 1977 (Neill and Kuban, 1986). The habitat sampled (Village Creek Water Treatment Plant Solids Drying Bed) has remained relatively stable through the years. Even in years of severe drought, adequate foraging area has been available for migrant shorebirds. The drying beds have, in effect, provided a minor staging area for the migrants and an alternate feeding site to Cheyenne Bottoms. Although 12 of the original rectangular drying beds were condensed or otherwise altered, the total foraging area used by shorebirds was not reduced. Censusing techniques were described previously by Neill and Kuban (1986). The 20 most common shorebirds observed in migration from 1977 to 1986 were compared to the number recorded in 1987 and 1988. The species are listed in order of their relative abundance in spring migration from 1977 to 1986 (Neill and Kuban, 1986). In spring migration, 90% of the shorebirds exhibited at least 20% reduction in population when compared to the 10-year average, and 65% declined by >50% (Table 1). Similar reductions were observed during fall migration with 13 species being reduced from the 10year average by at least 20%. Eight species showed average flock size to be reduced by at least 50%. The spotted sandpiper, solitary sandpiper and semipalmated sandpiper were recorded in greater numbers than the 10-year average. If the major staging grounds in migration (i.e., Ch yenne Bottoms) have been depleted and if North American populations have remained relatively stable through the years, an increased pop-
