Social networks of birds are often constructed from spatio-temporal data streams of feeder visits, but how do we define ‘connection’ and does it matter?
While common definitions yield similar patterns, do consider context of systems and research Qs!
Well led by co-first authors Alex and Jamie!
🧵👇
In this paper, we compared three approaches: (1) strict time-window, (2) co-occurrence, and (3) arrival time methods to define associations for house sparrows on Lundy Island, UK, and Broken Hill, Australia; great tits in Wytham Woods, UK; and sociable weavers in Benfontein National Park.

Age x G effects in telomere length in a wild bird! How cool is this? Another excellent paper by one of our PhD students, Janet Chik! doi.org/10.1093/evle...
Heritability and age-dependent changes in genetic variation of telomere length in a wild house sparrow population
Abstract. Telomere length (TL) and/or its rate of change are popular biomarkers of senescence, as telomere dynamics are linked with survival and lifespan.

Our study used social data from the Lundy house sparrows and found that older birds have fewer friends and less influence within their social networks -- royalsocietypublishing.org/doi/10.1098/...

We suggest this is driven by morality, and that the benefits of being social may decline with age.

We've had a paper published today in @avianbiology.bsky.social.

We demonstrated that some elements of Manx shearwater calls can be used to identify individuals. Something long-suspected, but not tested.

In future, this could be used to measure site fidelity or breeding group size. #ornithology

The awesome @yuhengsun.bsky.social showed that manx shearwater calls are individual - meaning they could use them as names! Absolutely fantastic publication from a masters thesis! @jamiedunning.bsky.social onlinelibrary.wiley.com/doi/10.1111/...
