The tag alias #61075 spread_wing -> spread_wings has been approved.
Reason: Alias a less-common singular (3) to a more-common plural (12,000+).
They mean almost the same thing. It's possible for a creature with two or more wings to only extend one of them, but I suspect this may be a case of "we don't want to cut it that fine". Of the 3 images tagged spread_wing, two of them show a character with two wings extended anyway.
Normally I would propose it the other way around (plural to singular), but I proposed it this way since the plural is so much more common.
EDIT: The tag alias spread_wing -> spread_wings (forum #355994) has been approved by @gattonero2001.
