Although many species of weavers move about extensively during the dry season, these are local movements rather than predictable, long-distance migration. The red-billed quelea (Quelea quelea) does carry out predictable movements in many regions, and these seem to be correlated with rainfall patterns. This appears to be the only species that could qualify as a migrant throughout its range.

Although they may have a wide range of different calls, few weavers would be considered "songbirds" in the conventional sense. The songs that male weavers use to advertise their territories are often a harsh, repetitive chatter with no tuneful, musical notes. Some forest species do sing short phrases, sometimes as duets, which are more attractive to our ears. The parasitic indigobirds learn elements of the song of their host species while in the nest, and later incorporate these into the songs which they use in courtship.
