The Hummingbird Web Site Presents:
Ruby-throated Hummingbird Migration Ruby-throated Hummingbirds normally spend the winter in Central America. From March through May they migrate north, some through the eastern two thirds of Texas, some apparently through Cuba and Florida, and some apparently directly across the Gulf of Mexico. Birds reach the southern Gulf coast in late February and early March. Later migrants fly to breeding grounds further north. The farther north they are going the later they travel. Arrival time on the breeding grounds tends to not occur until food plants are blooming. Departure time also corresponds with the end of the blooming season for food plants. Fall migration lasts from late July until late October in the southern states.Be sure to look at the excellent Migration Maps in Lanny Chambers' Hummingbirds! site (external link). Black-chinned Hummingbird Migration In spring Black-chinned Hummingbirds can be seen returning to Texas, New Mexico, and Arizona from mid-March through May. They reach Southern California by late March. It may be May before the species reaches the northwest states and British Columbia. In fall they leave west-coast areas in mid-August and September. In Texas they are usually gone by mid-October. Most Black-chinned Hummingbirds winter in Mexico.
