 Orchard
Oriole
During the breeding season, Orchard Orioles
range from the southern parts of the Canadian Prairie
provinces, southern Ontario, central New York, and
southern New England south to northern Florida, the Gulf
coast, Texas and central Mexico. They are most common,
however, in the Midwest and Southeast. They occur in open
woodlands, areas of open second growth, orchards,
suburban streets, in riparian areas, and in scattered
groves of trees. They show a preference for nesting near
water, often along the shores of lakes and rivers.

Oriole Range Map
Orchard Orioles spend most of the year on their wintering
grounds in Central America and northwestern South
America. Northbound migrants leave the wintering grounds
in March and begin arriving in the southern United States
as early as late March, reaching the northern parts of
their range by mid- to late May. Some migrants journey
across the Gulf of Mexico. Orchard Orioles spend only
enough time on the breeding grounds to raise a single
brood before beginning their southward migration.
Nests form a deep, hanging cup, although not as pendulous
as those of Baltimore Orioles (I. Galbula), and
are invariably woven of grass fibers. They are usually
hidden within dense foliage, often in a dense cluster of
trees. In the South, nests are frequently located within
clumps of Spanish moss. Sometimes Orchard Orioles nest
near Eastern Kingbirds whose aggressive defense of their
nesting territory also benefits neighboring birds.
The male Orchard Oriole sings more to attract a mate than
to defend territory. They are only weakly territorial and
defend just a very small area around the nest. One song
type is short, lasting approximately two seconds, and
sounds similar to the song of a Purple or House Finch. A
second song type is longer, lasting three to five
seconds, and consists of clearer, robin-like whistles,
ending in a distinctive down-slurred note.
The young leave the nest 11 to 14 days after hatching.
Once fledged, the brood may disperse, the parents caring
for groups of fledglings separately. As soon as
fledglings are independent enough to care for themselves,
Orchard Orioles begin moving south, as early as mid-July.
During migration they may be found in a wide variety of
open habitats, but avoiding coniferous woodlands and
forests with closed canopies. Unlike most songbirds,
which undergo a molt before leaving the breeding grounds,
molt is suppressed in Orchard Orioles until they arrive
at their tropical lowland winter home. Once there, they
forage and roost in flocks that can number in the
hundreds. While in the North, they feed primarily on
insects; in winter nectar, flowers and fruit are
important to their diet.
Description: Orchard Orioles are
comparatively small orioles, only six to seven inches in
length (compared to Baltimore Orioles, which are 8 ¼
inches). Males have a color pattern superficially similar
to that of the Baltimore Oriole except that they are deep
chestnut (the only icterid that is largely chestnut)
rather than orange on the underparts and rump. The head,
back, and tail are black. There is a chestnut
"epaulet" on the shoulder, and wings are black
with a single broad white wingbar and white edges on the
flight feathers.
Adult females have olive-green upperparts and yellowish
underparts. There are two white wingbars. First summer
males are similar to females but have a black bib and
face. Some show a variable amount of chestnut feathers on
the breast. First summer males sing and may mate
successfully.
While adult male Orchard Orioles are distinctive, females
may be mistaken for a number of birds, including
warblers. They are most similar to female Hooded Orioles,
a larger, southwestern species with longer tail; longer,
more curved bill; and gray rather than olive tones on the
back.
The Fuerte's Oriole is currently considered conspecific
with Orchard Oriole. It occurs in coastal and edge
habitats along the Mexican Gulf coast in the breeding
season and winters on the Pacific coast. It has been
reported from south Texas. In male Fuertes Orioles, the
chestnut color is replaced by ochre, and females are
somewhat paler.
Where common, Orchard Orioles sometimes nest colonially.
There are records of as many as 20 nests in a single live
oak tree in Arkansas, and as many as 114 nests made up
one colony on 7 acres in Louisiana. In the Northeast,
however, they are usually solitary and local.
