Why Africa's smallest raptor has helpers to raise its chicks

https://www.news.uct.ac.za/news/research-office/-article/2019-02-25-why-africas-smallest-raptor-has-helpers-to-raise-its-chicks

Abstract: Helpers improve fledgling body condition in bigger broods of cooperatively breeding African pygmy falcon

https://link.springer.com/article/10.1007%2Fs00265-018-2630-3


The researchers found that about 25% of the helpers in a pygmy falcon nests were female, which contrasts with other raptor species where female helpers are relatively rare.
