Thanks so much, Sophie ☺️ Really lovely to see you too!

7/7 Huge thanks to @thomasbodey.bsky.social @bescott-abdn.bsky.social Ana Payo-Payo, Al Baylis, @raorben.bsky.social Amandine Gamble, @isotopesuk.bsky.social @ronamcgill10.bsky.social @jasonisotopes.bsky.social @quadratdtp.bsky.social @saerifi.bksy.social @uniofaberdeen.bsky.social

6/7 Key takeaway: it’s important to remember that all populations are made up of unique individuals & this ultimately affects the results & conclusions of our research; we especially need to consider this when making inferences from studies at the population or even species level.

5/7 Repeatability is really useful for comparing populations & addressing wider Qs, & indeed, we found specialists within our generalist spp. But only when considering multiple traits at the individual level can we start to identify nuance in variation, even for colonies with little repeatability.

4/7 Using Kvalseth’s Coefficient of Variation to study individual repeatability, we found evidence of repeatability & variation among individuals & traits at all colonies.

If only studying one colony/trait we'd reach different conclusions about how repeatable individuals are within a population.

3/7 We deployed GPS & TDR tags to explore foraging behaviour & collected feather & blood samples to explore diet through stable isotope analysis (d13C & d15N).

We extracted metrics & analysed repeatability using rptR, finding differences in repeatability both among & within colonies.

2/7 By studying breeding #FalklandsShags at several colonies we asked: Are specialist birds consistently specialist across a range of traits such as diet & foraging behaviour, or does it simply depend on the trait being studied?
