flightless
Wings but earthbound
Flightless describes birds and insects that cannot fly, despite belonging to groups that typically can.
Penguins, ostriches, and kiwis are flightless birds—their wings have evolved for other purposes or atrophied.
The dodo was a flightless bird native to Mauritius.
The term sometimes extends figuratively to anything grounded or unable to take off.
