The Baltimore Oriole bird makes its way from Mexico and South America its wintering grounds, to the US and Canada to begin its mating, nesting, and feeding habits.
The male bird is black with orange underparts, rump, shoulders, and sides of tail. His wings have 2 white wing bars. The females is olive above, yellowish below with 2 white wing bars. This particular Oriole bird is found east of the Rockies.
Its western counterpart; the Bullock's Oriole, is similar in appearance. Orioles at Feeder - Check This Feeder Out Here While the major league team adopted this birds name and colors, the bird itself, got its name from George Calvert, Lord Baltimore, a 17th-century nobleman whose coat of arms used the same colors.
Because the two birds interbreed in the Central Plains and have similar types of habits, the American Ornithologists Union renamed both birds and called them The Northern Oriole. The mating season begins in late April to early May. The males arrive 2 or 3 days before the females and begin claiming their territories. Singing from treetops in their effort to attract a mate. Their singing is almost constant until they mate with a female. Unlike the Northern Mockingbird though, these birds do not sing at night.
Generally, any singing late in the season is from unmated or immature birds. Once the birds have found a mate they defend their territory and begin nesting. Once the female selects a male a nest site is chosen that is within the males territory. Building a hanging nest made from plant fibers and suspended from a branch 6 to 90 feet above ground.
While it's quite common for them to return each year to the same territory, it's rare that they will use the same nest itself. They often take parts of old nest to build a new one, so you may see them at the old nest site. Eggs and young birds are especially vulnerable to predators such as squirrels, owls, large birds , and domestic cats. Adults put up a fight by sounding alarm calls and mobbing predators. Baltimore orioles primarily eat insects in the summer, but switch to nectar and fruit in the fall, preferring to eat dark-colored fruits.
Males court females with songs and visual displays. An interested female responds by fluttering her wings and calling back to him. The nest of the Baltimore oriole is quite extraordinary—it's sock-shaped, woven with a number of materials, and hangs from a slender tree branch.
These hanging nests are built many feet above the ground and must be sturdily built to support the weight of the three to seven eggs a female will lay. After hatching, the young are fed by their parents for about two weeks, until they leave the nest. Baltimore orioles can live up to 11 years in the wild and even longer in captivity. Overall, Baltimore oriole numbers are stable.
There is a small decline to their population in the eastern United States, but this is compensated for by an increase in the western part of their range. These birds are threatened by deforestation and pesticide use on trees. They can easily be enticed into a backyard with native fruit and nectar-producing plants or hanging feeders of sugar water. The Baltimore oriole was named because its coloring is similar to the colors on the heraldic crest of Lord Baltimore.

May is the peak month for nest-building. Bullock's orioles finish their migration up the coast, and most reach their interior mountain and plains breeding grounds.
Nesting peaks in May and early June. June This is the month most baby Baltimore orioles hatch. Parents are busy incubating eggs and raising babies. Bullock's orioles are busy with eggs and babies. Baby-rearing peaks this month.
July As Baltimore oriole babies become independent, parents begin molting their body and flight feathers, and some are already starting to migrate at the beginning of the month! Bullock's orioles are still busy with babies in parts of their range, and also starting to molt their body feathers. Ornithologists are still collecting data about the molt of their flight feathers.
They leave the drier areas of Washington and California by the end of the month. Birds are steadily molting their body and flight feathers. Bullock's oriole migration peaks this month--few birds remain in the northern part of their range past August.
