New paper published
Kai, a member of our raptor team, has collaborated with statisticians from Salzburg to develop a new method for measuring the niche overlap of several species simultaneously. The breeding site and habitat data of the common buzzard, red kite and eagle owl were used as a data example.
Curious? Read the paper A Novel Method for Nonparametric Statistical Inference for Niche Overlap in Multiple Species

Many congratulations to Hugo for submitting his thesis about: Microbioms in the wild: insights from avian species
Congratulations!
Svenja, a PhD student in the Galapagos Sea Lion Project, recently presented some of her results at the International Conference for Young Marine Researchers (ICYMARE) in Bremen. For this she received one of the prices for "Best Talk".
Now Svenja and her colleagues are heading back to the Galapagos for the annual field season to collect more interesting data on the Galapagos sea lions (Zalophus wollebaeki). Good luck in the field!
New paper published
Hugo and colleagues investigated the interactions between gut microbiota, immune function, and stress during early development in common buzzard nestlings (Buteo buteo). While they found no feedback between gut microbial diversity and immune or stress parameters, they identified strong relationships: immunity was negatively correlated with stress levels; stress levels were negatively associated with body condition; and microbial diversity was positively linked to improved nestling body condition.

New paper
In their study, Sabine and colleges investigated long-term consequences of the early family environment on individual differences in lifetime fitness in female cavies (Cavia aperea).
If you want to know more about how initial size differences among siblings translate to size differences in adulthood and how different litter characteristics affect maturation and reproductive output of female wild cavies, check out the paper Long-term effects of litter characteristics on reproduction in female cavies
Welcome Gaia!
Gaia recently graduated in MSc Biodiversity, Conservation and Environmental Quality. She is doing an Erasmus for traineeship after-graduation to study prevalence and abundance of Haemosporidian parasites in migratory birds, which will be sampled at a ringing camp in Bulgaria. Welcome to the VHF and buzzard team!
Welcome Simone!
Simone joined the Raptor Group to study the behaviour of birds of prey for his MSc thesis in Evolutionary Biology. He is focusing in particular on the aggression of buzzards and nest defence behaviour towards predators. To look into these aspects, he is carrying out some field experiments. Welcome to the VHF and buzzard team!
Paper published
Does the degree of sexual competition influence the gene expression profiles of the testes and two brain areas in male zebra finches? Navina and her colleagues addressed this question and present their findings in their paper: Transcriptomic changes in the posterior pallium of male zebra finches associated with social niche conformance
Review published
In behaviour, ecology and evolution, we are very interested in how phenotypes interact with their environment. The review by members of our NC3 initiative focuses on the importance of social competition.

PhD thesis handed in!
Many congratulations to Stephen for submitting his thesis about: Individual risk and reward in the wild - A study on blue tits
A deep look inside the buzzards
Hugo and colleagues have looked at the complex interplay between microbial communities, host factors, and environmental variables. Find out more in their recently published paper "Early-life factors shaping the gut microbiota of Common buzzard nestlings"

A visit to Vilnius
Two members of the raptor research team have recently been welcomed at the Parasitology Lab of the Nature Research Center in Lithuania. The research group is based in Vilnius and renowned for its work on avian blood parasites. In the course of two exciting weeks the team from Bielefeld was trained in several parasitological methods. This will help the raptor researchers tackle some outstanding questions regarding host-parasite interactions in their study population.

Happy Birthday VHF!
The VHF has turned 50!
Many former and current members of the VHF came together to celebrate.
The programme of the celebration started with a report by Fritz Trillmich on the history of the VHF. We then had the pleasure of hearing Norbert Sachser give the legendary Immelmann Lecture, followed by Oliver Krüger's report on the future of the VHF. Finally, of course, there was plenty of time for socialising and celebrating.New paper in BMC Zoology

Successful field season
© Tim Rapp 2023 was a quite outstanding year for the raptor research team at the Department of Animal Behaviour. In almost 30 years of monitoring, the number of breeding attempts has never been higher, while the number of sampled buzzard nestlings (476) matched the previous record. The team also gathered extensive footage through 15 nest cameras and equipped 30 birds with GPS-GSM transmitters!

Come January 2022, she will be carrying out research at the University of St. Andrews in the UK in collaboration with Dr. Michael Morrissey. She plans to pair newly collected micro-meteorological data with data from the long-term research project of wild Soay sheep to test the hypothesis that incorporating fine-scale, individual-based environmental conditions into multivariate trait-fitness regression models will produce more robust predictions of selection.

Wiley Online Library, CC BY-NC 4.0 Anja and Fritz investigated behavioural developmental phenotypic plasticity of juvenile cavies in response to photoperiod. Cavies are highly precocial and reproduce multiple times within a year. This makes them an ideal study species to determine whether such adjustments occur and are adaptive with respect to pace-of-life syndrome (POL).

Student project available!
© Rebecca Nagel The immune system protects individuals against pathogens and parasites, but investing into immunity is costly! Energy expenditure on immunity can vary depending on individual characteristics and environmental conditions, such as age and population density. We want to figure out what factors are most important for Antarctic fur seals. Do do this, we have blood smears from seal pups and mothers, and we want to count the number and type of white blood cells. This will also tell us something about the types of infections and diseases Antarctic fur seals are exposed to.
If you are interested in helping with this project (both bachelor and master students are welcome) or would like to find out more, please get in touch with Rebecca Nagel (rebecca.nagel@uni-bielefeld.de) or Joe Hoffman (joseph.hoffman@uni-bielefeld.de). We look forward to hearing from you!
