The webbird first appeared in first edition Advanced Dungeons & Dragons in the original Monster Manual II (1983).
The webbird appeared in the third edition of Dungeons & Dragons in Dungeon #148 (July 2007).
A webbird is a feathered creature found in semi-tropical lands, usually inhabiting the fringes of woodlands so it can seek prey in nearby open ground. A webbird appears to be a beakless bird, about raven-sized, with long-feathered wings and a long spikey tail; it is not actually avain, but might be some form of insect or arachnid. It has a slitted mouth with hard, sharp ridges for biting and a drooping 4-inch long chest appendage. A flock of webbirds can take to the air, then gather over the heads of victims, emitting a strand of sticky, inflammable web. A webbird will alight with immobilzed prey, inserting its chest appendage in exposed flesh and injecting eggs; grubs hatch from these eggs after a few minutes and eat the host from within, causing excruciating pain.
