We conclude that considering the costs of extra-pair behaviour can improve our understanding of the drivers of (variation in) this behavior.
Females can experience loss of parental care (although this is still poorly understood!), STDs, harassment, divorce etc. However, there are also costs for males, including reduced paternity, search costs, STDs and mate guarding.
… When I took my masters on EPP in house sparrows, I wondered a lot about this. So did @j-dunning.net, who took his PhD on EPP at that time, also on house sparrows! So, together we reviewed what is already known about the costs of EPP.
New paper out in Biological Reviews📝🚨
When trying to explain why female birds engage in extra-pair copulations/paternity, we mostly focus on the benefits.
But what about the costs? Should we not consider the downsides of the behavior we try to understand? 🧵

🎦 I’ve had the pleasure of working with Chris Perrins lately. He has been a monumental figure within avian ecology for nearly 70 years. He is also a very nice and pleasant person. So, I sat down and chatted to him about his life in science. Here is the result. ⬇️

🎥🎞️The last EGI seminar of the term (but don’t worry, we will have one extra seminar in April), given by Jennifer Morinay on what determines helping behavior in long-tailed tits is now uploaded to our YouTube-page!

In our new paper, published yesterday, we use the long-term data set of Wytham Woods to show that great tits have maintained stable temperature at breeding despite the almost 2ºC increase in Spring temperature. w. E. Cole, C. Regan & @sheldonbirds.bsky.social Link -> www.science.org/doi/10.1126/...
Planning a nestbox temperature manipulation experiment in birds? We’ve just published a preprint that may be useful! 🪺🪶
We review 46 studies and also share our own blue tit pilot experiment from Wytham Woods, highlighting some very real practical challenges doi.org/10.32942/X25387
Very pleased to welcome Dr Alexandra Cones (LMU Munich) for an EGI seminar in @biology.ox.ac.uk at 4pm this Friday 17 April. Alexandra will speak on "Embracing Complexity: Untangling sources of phenotypic variation across scales using birds" - also live-streamed: joining details below: ⬇️
Scarcely into June, and already more or less completed this year's tit field season in Wytham, marked with the now traditional group photo. Great teamwork once again led by @mcmahok.bsky.social with excellent support from @ellafcole.bsky.social & Sam Croft. Will update with some data summaries soon!
