Examples of Animal Behavior Research
Animal behavior research can involve a wide range of animal species and research subjects. In ethology, animal behavior is studied under natural conditions. Ethology has its roots in the scientific work of Charles Darwin (1809-1882), as well as Dutch biologist Nikolaas Tinbergen (1907-1988).
Ethology combines laboratory and field science, and also has strong relations to other disciplines, such as neuroanatomy, ecology, and evolutionary biology. Researchers in this field of study are interested in understanding the functions, causes, development, and evolution of animal behavior.

Observing monkey behavior and their use of tools
We already know some monkeys display above average intelligence. Behavioral studies have shown that capuchin monkeys use tools suck as boulders and logs as anvils upon which they can crush nuts. Fragaszy et al. studied a group of wild capuchin monkeys in Brazil, specifically the placement of nuts prior to striking them. An interesting detail: they studied this same behavior in humans as well.

Interactive enrichment for great apes
There is growing empirical support demonstrating improved welfare in captive animals when they can exert control over their environment. Research shows that great apes can successfully interact with digital media devices and can demonstrate behavioral changes when presented with digital enrichments.
Nicky Kim-McCormack and her colleagues from Australian National University studied the effects of digital enrichment on animal welfare. They included Seoul Zoo’s six orangutans and four chimpanzees in their study.

Neuroscience research with guinea pigs
According to Kiera-Nicole Lee and her colleagues, guinea pigs differ from mice and rats, and that just might make them more suitable for some neuroscientific studies. This is due to the fact that results from studies with guinea pigs are more easily translated to humans.

Domesticated vs wild animals
Not many studies have compared the behaviors of wild and domesticated animals. When they do, such as with guinea pigs, they mostly compare adults.
Zipser et al. were curious to find out whether the differences in behavior between domesticated guinea pigs and the wild cavies were also found earlier on, and so they compared these species during the early and late phase of adolescence.

Chicken welfare
There are almost 100 million chickens in the Netherlands — that's about 17 times as many chickens as people. Their welfare has improved enormously in the past few years, but there is still plenty of room for improvement.
In the ChickenStress project, we work with different partners to improve chicken welfare and reduce problems like feather pecking.

Spatial behaviors in sheep
The study of movement, activity, and behavior is valuable in research on animal health and welfare, specifically in livestock research. Understanding animal behavior in different environments provides insights that can help improve their living conditions.
There is still a lot to learn about the behavioral and social patterns in sheep. At the Aberystwyth University in Wales, UK, researchers used TrackLab for tracking and detailed analysis of spatial behaviors in sheep.

A rat model for Parkinson's disease
Parkinson’s disease is a neurodegenerative disorder that affects mobility in a life-changing way. Slow movement, shuffling of the feet, and difficulties initiating movement are all impairments we recognize as typical for this disease.
Researchers Jordi Boix and his colleagues, from the University of Auckland in New Zealand, used two rat models to investigate a number of gait parameters. Their aim was to find resemblance to human symptoms, and to specifically find them early on.

How to monitor rat social behavior
Monitoring and analyzing the social behavior of group housed rodents is something that many researchers find extremely challenging. It can also be very time consuming. However, including social behavior as part of a phenotypic screen has important benefits, and eventually leads to better translational value of rodent models. During her PhD research, Suzanne Peters developed an automated analysis that allows for the monitoring of socially interacting rats.

How fruit flies find your food (and mates!)
Those tiny flies that take over your garbage cans in the summer? They are called fruit flies for a reason! They have a fantastic sense of smell. Drosophila melanogaster (or fruit flies) are a popular animal model for researchers, because they have a fairly similar genetic makeup to our human genome, and they are easily manipulated to create genetically different strains. For neuroscientific studies, this makes them a really good model to learn about the effects of genes on behavior.
Find out what researchers discovered about fruit flies and their smell.
Zebrafish studies
The zebrafish has become an important vertebrate model to study (developmental) neurobiology and behavior, not in the least because of recent improvements in transgenic, optogenetic and imaging techniques, and behavioral assays.
More and more studies with zebrafish are conducted. Some examples:
- A new zebrafish model for ALS-related gene mutations
- How to measure complex exploratory behavior in larval zebrafish
- How optogenetics is used to study the stress response in zebrafish larvae
- Social buffering in zebrafish
- Strain differences in zebrafish behavior and physiology
