Several weaver species regularly build nests with long entrance tubes, although some individual nests have shorter tubes:
Baya Weaver
Black-throated Weaver
Nelicourvi Weaver
Dark-backed Weaver
Black-necked Weaver
Spectacled Weaver
Gola Malimbe
Cassin's Malimbe
Red-bellied Malimbe
Ibadan Malimbe
Rachel's Malimbe
Red-vented Malimbe
Red-headed Weaver

Often long tubed nests are built by solitary, monogamous weavers. This group of weavers usually consists of a pair and they build the nest together. In some malimbes, a group of birds help build a nest. The long tube probably reduces predation but does not stop some predators. In the polygnous weavers it is usually the male that builds (although the female lines an accepted nest) and males want to build many nests in a breeding season, rather than spending energy on building nests with long tubes.

A few weavers do not normally build long entrance tubes on their nests, but may occasionally do so: White-browed Sparrow-weaver, Streaked Weaver, and Sakalava Weaver.
