2 Types of Orioles in Maryland: How to Identify and Attract Them
September 21, 2026
Nine oriole species live somewhere in the United States, but only two of them raise their young in Maryland each year. Blackbird family members through and through, these orioles bring a jolt of color to backyards from spring through late summer, and knowing the difference between the two types of orioles in Maryland can turn a fleeting glimpse into a confident identification.
One species is impossible to miss once it settles into a shade tree. The other is quieter, rarer, and often overlooked by anyone not specifically watching for it. Below is a breakdown of both birds, including how to tell them apart, where they nest, and what to put out if you want either one visiting your feeders this season.
Baltimore Oriole
The Baltimore Oriole (Icterus galbula) is the state bird everyone in Maryland recognizes, even people who couldn’t name another local species. It earned that title officially, as Maryland’s state symbols page notes, the Baltimore Oriole is the official Maryland bird under Chapter 54, Acts of 1947. The name itself predates the designation by centuries, coming from the black-and-orange coat of arms of Lord Baltimore, the colonial proprietor for whom the city was named.
Adult males are unmistakable. According to the Maryland Department of Natural Resources, male Baltimore Orioles are flame orange and black with a solid black head and orange sides, while females and immature birds are brown above and burnt orange below with two white wing bars. Older females can develop a partial black hood, which occasionally confuses birders expecting a clean split between the sexes. In terms of size, the Chesapeake Bay Program reports that Baltimore orioles are between 6.5 and eight inches in length and weigh one to 1.5 ounces, making them slightly smaller than a robin.
Pro Tip: Look up before you look around. Baltimore Orioles spend most of their time high in the canopy, so scanning treetops rather than shrubs will save a lot of frustrated searching.
Timing matters for anyone hoping to spot one. Maryland DNR advises that birders should look for the migrating orioles to return to Maryland in March through April. They stay through the breeding season and largely disappear by late summer, since most orioles start to migrate south in August, wintering in Central and South America.
Diet drives a lot of Baltimore Oriole behavior. Maryland DNR lists their food sources as caterpillars, beetles, scale insects, woodborers, aphids, sawfly larvae, and grasshoppers, supplemented with fruit. Anyone who has read up on caterpillars found in Maryland or the state’s beetle species will recognize a good chunk of the oriole’s menu. On the fruit side, the birds are surprisingly picky. The Chesapeake Bay Program notes that orioles prefer dark, ripe fruit like mulberries, cherries and purple grapes and will ignore lighter fruit like green grapes.
Nesting habits are just as distinctive as the plumage. Maryland DNR describes how the oriole breeds throughout Maryland in large trees in open areas along country roads, in towns, or edges of woods near streams, favoring maples, sycamores, birches, apples, black cherry, and oaks, where the male builds a sturdy pendulous pouch nest. That woven, sock-shaped nest is one of the easiest ways to confirm a Baltimore Oriole has been in the area, even after the birds have moved on.
- Best attractants: orange halves, grape jelly, and sugar-water nectar feeders
- Habitat to watch: open woodland edges, shade trees, and orchards near streams
- Peak viewing window: late March through July, before southbound migration begins
The nectar-feeding habit surprises a lot of new birders. As one longtime Maryland backyard birder puts it, Baltimore Orioles, similar to hummingbirds, love drinking nectar from flowers, which is why the same sugar-water setups used for hummingbird species that visit Maryland also work well for orioles, provided the feeder ports are large enough. The Cornell Lab of Ornithology recommends cutting oranges in half and hanging them from trees, noting that special oriole feeders filled with sugar water supplement the flower nectar that Baltimore Orioles gather.
Important Note: Maryland DNR reports that Baltimore Orioles have declined significantly in the eastern U.S., with the decline in Maryland approaching a rate of 2% annually. Providing reliable food and nesting habitat helps support local populations.
Orchard Oriole
Maryland’s second oriole is easy to miss if you’re only picturing flame orange. The Orchard Oriole (Icterus spurius) trades that bright color for something more subdued, and it nests in far smaller numbers statewide than its Baltimore cousin. Bedford Audubon Society describes it as a bird that has an extraordinary, though subtler, beauty of its own compared to the more familiar Baltimore Oriole.
Cornell’s All About Birds guide sums up the color difference simply: the Orchard Oriole swaps the typical flame-orange of other orioles for a deep, burnished russet. Size is another giveaway. Cornell’s species-comparison page notes that Orchard Orioles are noticeably smaller than Baltimore Orioles, and male Orchard Orioles are rich chestnut, never bright orange like Baltimore Orioles. Females can be trickier, but Cornell points out that female Orchard Orioles never show any orange tones like female Baltimore Orioles, and they have unmarked grayish-yellow backs while female Baltimore Orioles show streaking.
Bedford Audubon offers a useful field description of the male, noting that the adult male is almost identical in pattern to an adult male Baltimore, but the underparts are a rich, dark chestnut with an entirely black tail, while the female is mostly greenish yellow with a light gray back and dark gray wings marked by white wing bars. If you’re comparing colorful species around the yard, it’s worth also checking a guide to purple birds in the region or green birds found in Maryland, since misidentified silhouettes and lighting can make orioles look like something else entirely.
Habitat preference is where the name comes from. As the Bedford Audubon Society explains, Orchard Orioles are found in habitats similar to those occupied by Baltimores, but are much more sparsely distributed and seem especially fond of locations near bodies of water such as streams and lakes. That fondness for open, semi-wooded ground near water lines up with a description from Birds & Blooms, which notes that the orchard oriole favors short trees and semi-open areas, such as orchards or the edges of woods, rather than deep forest canopy.
Orchard Orioles are also more social than you might expect. Cornell’s overview notes that Orchard Orioles are relatively easygoing toward each other or other bird species, nesting in close quarters with Baltimore Orioles, Bullock’s Orioles, Eastern Kingbirds, Western Kingbirds, American Robins, and Chipping Sparrows. That tolerance even benefits the birds directly, since the aggressive kingbirds may be useful neighbors because they ward off predators and cowbirds that would otherwise lay eggs in the oriole’s nest.
The species also has a documented longevity record tied directly to Maryland. Cornell reports that the oldest Orchard Oriole on record was a male at least 11 years old when he was recaptured and rereleased during banding operations in Maryland in 2012. If you can’t spot one, listening might help, since the Orchard Oriole’s song, a rich, jumbled warble, is the one area in which it might be said to outdo the Baltimore in flair.
| Feature | Baltimore Oriole | Orchard Oriole |
|---|---|---|
| Male color | Flame orange and black | Deep chestnut and black |
| Relative size | Larger, robin-adjacent | Noticeably smaller |
| Preferred habitat | Shade trees, woodland edges, towns | Orchards, open edges near streams |
| Abundance in Maryland | Most commonly seen oriole statewide | Sparser, more localized |
| Arrival timing | March through April | Slightly later than Baltimore Oriole |
Baltimore Orioles are the most commonly seen oriole in Maryland, which explains why Orchard Orioles get overlooked even by experienced birders. Timing your feeder setup matters for both species, but especially for the less common one. Duncraft’s feeding guide notes that Baltimore Orioles begin arriving in spring during migration, often between April and May depending on location, while Orchard Orioles may arrive slightly later. Once the season winds down, the departure follows a predictable pattern too, with females beginning to leave by mid-August and males remaining on territory into mid-September.
- Feeder foods that work for both species: grape jelly, fresh orange halves, and diluted sugar-water nectar
- Recommended nectar ratio: oriole nectar mixed at one part sugar to four parts water, plus mealworms during nesting season for extra protein
- Setup timing: have feeders ready by mid-to-late April in northern regions so they’re in place before the birds arrive
Because Orchard Orioles nest near water and favor smaller trees, checking areas along creeks and pond edges gives better odds than scanning a typical suburban shade tree. Anyone already tracking backyard insect activity for Maryland’s butterfly species has a head start here, since caterpillars that feed local butterfly populations make up a share of the oriole diet as well.
Spotting either oriole in Maryland comes down to patience and preparation. Getting feeders out early, planting fruit-bearing trees and shrubs, and knowing what separates a flame-orange Baltimore Oriole from a chestnut-toned Orchard Oriole will make the short window each summer far more rewarding. Between the two species, Maryland backyards get a genuine, if brief, taste of some of the most striking songbirds in the eastern half of the country.
