The South Carolina Department of Natural Resources (SCDNR) will conduct an annual Baltimore Oriole Winter Survey Feb. 15-18 in conjunction with the Great Backyard Bird Count. The state natural resources agency is interested in the status and distribution of these colorful songbirds that have begun wintering in the Palmetto State.

Survey participants count and record the largest number of Baltimore Orioles they can see at one time, on one, two, three or all four days of the survey period. Even if you are not able to participate during the count period, we would still like to collect your numbers. You can participate in the survey by either requesting an SCDNR survey form, or if you are a Great Backyard Bird Count participant, you can e-mail a copy of your checklist submission to SCDNR. For more information and to receive survey materials, contact Lex Glover at For more information on the Great Backyard Bird Count, visit

Baltimore Orioles usually winter in South and Central America, and historically it was unusual to see one in South Carolina during the winter. However, during the last few decades, they have been wintering along the East Coast and Southeast in greater abundance. Last year’s Great Backyard Bird Count results had sightings ranging along the east coast from Massachusetts to Florida, with the bulk of the birds wintering from Virginia, south to Florida, There were a scattering of reports from the Gulf States and as far west as California. South Carolina Winter Baltimore Oriole Survey data combined with the Great Backyard Bird Count data had South Carolina with the largest numbers of orioles in 2018. South Carolina had 64 reports (28 percent of the total number of reports in the country) and 228 orioles tallied, (28 percent of the total number of orioles reported). South Carolina had orioles as far inland as Lexington County and along the coastal plain from Myrtle Beach to Hilton Head Island.

Though SCDNR is not sure why these birds have begun overwintering in the state, they are responding well to the popularity of backyard bird feeding. Orioles by nature have a “sweet tooth” and will eat nectar from flowers and wild fruits. Their favorite bird-feeding food by far is grape jelly. Orange halves can be used to attract the orioles into your yard, but grape jelly will encourage them to return. Other items they will eat are suet products (homemade, cakes, bark butter, logs, etc.), sugar water (they will drink from hummingbird or oriole nectar feeders), seed mixes (seem to prefer nut and fruit mixes), sliced grapes, mealworms (live or freeze-dried), sweet cornbread and pound cake.

During the winters from 2009-2015, SCDNR trapped and banded Baltimore orioles that frequented feeders around the state. SCDNR trapped a total of 1,148 birds at 41 sites; banding 990 and recapturing 158, representing 142 individuals. But the most exciting find was when one of the orioles banded in Myrtle Beach on March 8, 2011, was recovered on Sept. 23, 2015, in British Columbia. This is at the extreme western edge of Baltimore orioles’ known range.

The survey will enable scientists to learn distribution and abundance of Baltimore Orioles wintering in South Carolina. Information from the survey and Great Backyard Bird Count can provide a “big picture” about what is happening to Baltimore Oriole populations. SCDNR appreciates the public’s support and efforts with helping collect the valuable information in this survey.
