Authorities received reports of an emu on the loose on Interstate 10 near Phoenix, Arizona, at around 10am on Friday.
Arizona Department of Public Safety spokesman Quentin Mehr says a responding trooper found the bird in the median.
Mehr says a second trooper arrived and both officers drove alongside the animal to keep it from entering traffic lanes.
An officer from the Arizona Department of Agriculture then used a lasso to wrangle the emu into a trailer.
Authorities say it is still unclear how the emu came to be in the area.
