Wendy Rihner, Education Chair of the local chapter of the Audubon Society, will lead a two-night program on the fall bird migration at 7 p.m., Wednesday, Sept. 12 and 19, at the East Bank Regional Library, 4747 W. Napoleon, Metairie. Each event is free of charge and is open to the public. According to Rihner, �What flies north must fly south. The miracle of spring migration is only half of the fascinating life history of birds. Fall migration marks the end of nesting and rearing young, and it brings some remarkable physical changes for many species of birds. Many of our spring warblers look a lot different in the fall.� During this presentation, Rihner will discuss the following subjects and more:� The flycatcher species of eastern North America peaks in Louisiana during September.� Common migrants in September include blue grosbeak, indigo bunting and paint bunting, seeking native grass and weed seeds at the edges of agricultural fields.� Yellow warblers are common in the fall. They head directly to the Gulf Coast and then turn west to the coastal bend of Texas.� Many migrating shorebirds pass through Louisiana in September and October, including sandpipers, plovers, dowitchers, dunlin and Wilson�s snipe.� The majority of neotropical migrants peak during the third week of October. They include vireos, thrushes and tanagers that congregate around fruit trees and shrubs.
