4/4 The good news is that Co-BreeD is an updatable resource & once we reach 140 followers, we will post an updated, more accurate estimation! So, like, share & follow!

3/4 Cooperative breeders are currently over-represented in Co-BreeD (see paper). Yet, Co-BreeD has already identified more cooperative breeding mammals than reported in previous datasets (i.e. >57). So previous estimates are likely very much underestimated. The question is how much...

2/4 This is the % of species with at least 1 population exhibiting a systematic & unambiguous form of alloparental care out of the total number of species included in the Co-BreeD dataset.
If the % of cooperative breeders looks exaggerated to you, it is not for nothing (📸 @nataliekes.bsky.social)

Not sure. Probably was trying his/her luck... Giraffe caves do this...

Right, see the alt text for these images. Also, Co-BreeD curates parental care data on all bird and mammal species, regardless of whether they are cooperative breeders or not.

Thanks! ;)

6/6 We invite field researchers to submit data on parental care in ANY wild population of ANY bird and mammal species and/or to offer corrections. We offer FAIR co-authorship for data contributors! Email Yitzchak Ben Mocha [email protected]

5/6 Using Co-BreeD’s comprehensive data, we suggest that cooperative breeding is considerably more prevalent in birds and mammals than previously estimated (illustration @nataliekes.bsky.social) @anavleitao.bsky.social @miyawarrington.bsky.social

4/6 Yes, no, maybe? Quantitative estimates enable studying cooperative breeding as a continuous trait (bottom panel), rather than a binary one (upper panel), and demonstrate the ample variation in cooperative breeding across and within species @maikewoith.bsky.social

3/6 Linkage of each biological estimate to its exact sampling period and location enables linkage to unprecedented fine-tuned climatic and environmental data @odedkeynan.bsky.social @linde-makuya.bsky.social @dustinrubenstein.com

2/6 Co-BreeD is designed to include complementary datasets (e.g. % of breeding with alloparents, allonursing). It currently includes 501 samples from 460 populations of 324 species. This sample-based structure allows examining within-species & even within-population variation in cooperative breeding

Stay tuned for the first Co-BreeD dataset that should be published in mid-2025 with state-of-the-art data on >200 cooperative breeding birds and mammals!

8/8 Last, but not least, we emphasise that HUMANS are COOPERATIVE BREEDERS and, therefore, studying cooperative breeding species is a key to understanding the evolution of our own species!

7/8 To facilitate cooperative breeding research, we provide several supporting datasets, including the prevalence of social groups with potential alloparents in 138 populations of 88 mammal and bird species.

6/8 We conclude by presenting an inclusive operational definition that considers all species with systematic and proactive alloparental care as cooperative breeders.

5/8 We analysed data on alloparental care to suggest qualitative and quantitative criteria for what type, extent & prevalence of alloparental care should be required to classify species as cooperative breeders.
