Fairy-wrens are more likely to help a mate in the harsh of winter Superb fairy-wrens are more cooperative during winter and are more likely to respond to calls of distress from other birds when the weather is at its harshest, according to Australian research. Superb fairy-wrens are social songbirds who live in distinct breeding groups, are the researchers were keen to see how their level of cooperation changed as their environment changed. The study looked at how individual superb fairy-wrens respond to distress calls from other superb fairy-wrens, and found that at the beginning of the breeding season, calls were met with aggressive, territorial song, however, birds exhibited more cooperative behaviour when the same calls were played during winter. The authors suggest fairy-wren communities reorganise to favour cooperation in challenging environmental conditions.
