Marshes are divided into distinct zones, the high marsh and the low marsh. The difference in elevation between these two areas is usually only a few centimeters, but for the plants that inhabit each of these zones, a few centimeters makes a world of difference. The low marsh floods daily at high tide.alt marshes are a mosaic of snaking channels called tidal creeks that fill with seawater during high tides and drain during low tides. Fish species including flounder and mullet live most of their lives in marsh creeks. (top) Levees are areas of higher ground that border the marsh creeks.

Based on past research, approximately 90% of the nest will contain 2 eggs, 9% will contain 1 egg and 1% will contain 3 eggs. Eggs average 100 mm in length and 63 mm in width. Whooping crane pairs share in incubation of the eggs.Incubation lasts from 29 to 31 days.ortunately, egg predation is uncommon, and re-nesting by whooping cranes is believed to be rare. So, normally whooping cranes usually produce clutches of 2 eggs laid 48 to 60 hours apart. Incubation begins with the first egg laid. Therefore, hatching of the eggs does not occur at the same time.
