Number of dowitchers
observed foraging and engaged in other behaviors was significantly greater in tidal-pond habitat (P < 0.
With the exception of dowitchers, all species that exhibited differences in their abundance at the different sites preferred TCN over BP, while TCS was intermediate.
On the other hand, dowitchers were more common on BP, probably because its softer substrate allowed for more efficient feeding of these species.
Also, two hours after lowest tide, marbled godwits, semipalmated sandpipers, curlews, and whimbrels rested on the shore, whereas the smaller peeps and dowitcher continued to feed.
For example, the largest wetland had, at different times, the highest frequency of usage (far above expected in a Chi-square analysis) for bird species with as diverse habitat requirements as American White Pelicans, cormorants, Ruddy Ducks, Canvasback, Great Egret, peeps, dowitchers and American Pipit due to different water levels and dryness of mudflats.
Black-bellied Plovers and Killdeer typically used drier areas than did Buff-breasted Sandpipers and peeps, and both used much drier sites than dowitchers that needed deep and soft mud for probing.

Because of frequent identification difficulties, only 4% of all dowitchers were identified to the species level.
Only Willets occurred here in large numbers (peak 400 on 16 December 1993), but dowitchers, Black-bellied Plovers, and Western Sandpipers occurred in modest numbers during low water.
Bike or hike to three main marsh areas and see avocets, curlews, dowitchers
, and egrets (bring binoculars).
