Figure 3.25. Birds of the intertidal flats include the long-billed curlew (upper left) and willets 

 (five larger birds on right; wing bars visible on the two in flight). In the foreground of the mudflat 

 are two least sandpipers (the smallest shorebirds) and three western sandpipers (lower right). 

 Long-billed dowitchers are shown in the center of the mudflat (two on the left and two in the 

 middle), with two dunlins (black patch on shoulder) just behind the least sandpipers. All are 

 drawn in their winter plumage, as usually seen at Tijuana Estuary. The macroinvertebrates of this 

 habitat include lined shore crabs, yellow shore crabs, and abundant fiddler crabs (below, from left 

 to right). Mclntire collection, © 1986 by Zedler.
