Some weavers often nest in exotic vegetation, especially tall trees in man-modified habitits. This includes eucalypt trees (Eucalptus), which are otherwise not frequented by many indigenous birds. Smith 1974 (The utilization of gum trees by birds in Africa, Ibis 116:155-164) compiled a list of birds, including the weavers below. Additionally records are also listed.

For the Southern Masked Weaver and Cape Weaver there are particularly many records. For several species, there are PHOWN records, showing nesting in Eucalypts.
