An example is the migration of continental populations of Swainson's thrush Catharus ustulatus, which fly far east across North America before turning south via Florida to reach northern South America; this route is believed to be the consequence of a range expansion that occurred about 10,000 years ago. Detours may also be caused by ...
Plants generally make up the larger part of a bird's diet, especially during autumn migration and in the winter. [80] [81] The mallard usually feeds by dabbling for plant food or grazing; there are reports of it eating frogs, other amphibians, and fish, including carcasses.

Our ruby-throated hummingbirds, as they begin their long migration south, need more than just the ability to hover in front of a flower, delicately sipping nectar; they also need strength, stamina ...
mtDNA control region sequence data indicates that these birds are derived from ancestral American black ducks, being far more distantly related to the mallard, and that the two subspecies, as a consequence of their rather limited range and sedentary habits, are genetically well distinct already. [7] The Florida mottled duck (A. f. fulvigula)
Most hummingbirds migrate in the winter to Central America or Mexico, but some hummingbirds spend the winter on the Gulf Coast and may be found in South Texas and South Louisiana during mild winters.
