You may want to obtain a field guide to the area in order to know which birds to attract.
Phospholipids. Phospholipids make up an important class of lipids for the construction of cell membranes. The phospholipids are not true fats because they have one of the fatty acids replaced by a phosphate group.This sketch of a phospholipid molecule shows two fatty acids and a phosphate group attached to a glycerol backbone.hospholipids.

The Actual Cell membrane has proteins embedded in the lipid bilayer. Embedded in the phospholipid bi-layer are a diverse set of proteins which do most of the important functions of the cell membrane. This idea is called the fluid mosaic model of the cell membrane.Cell membranes are fluid in the sense that the molecules in the membrane are in constant motion. The mosaic part refers to the proteins embedded in the phospholipids.he Actual Cell membrane has proteins embedded in the lipid bilayer.
