Hunting is hard. Hunting in the snow? Even harder. A study on wild red foxes (Vulpes vulpes) in the Czech Republic indicates that these cunning hunters have an additional weapon in their arsenal—magnetic sensation! The study showed that foxes strongly preferred to pounce on their prey by jumping in the direction facing magnetic north east….

Field Frame Friday: No provisioning allowed!
When humans voluntarily feed wildlife, it is referred to as provisioning. Although this may appear a harmless and fun activity for visiting tourists, these small acts of “kindness” can have profound effects on wildlife. For example, provisioning can lead to increased aggression among individuals monkeys in a social group, as they are competing over a…

Sunday Sketch: Between a rock and a hard place
Long-tailed macaques (Macaca fascicularis) are one of the most common monkeys in southeast Asia. Some populations along the shore are found to use stones as tools to crack oysters, bivalves and various kinds of shellfish. This tool-related foraging technique is extremely rare among primates. The tool use behaviors are found only in some populations of monkey species in the same location despite sharing environmental…
Field Notes: PhD Research or Arts-n-Crafts Hour… Why Not Both?
When you’re in the business of making nearly a thousand clay caterpillars by hand, there are a few must-have investments: Spotify premium (for hours’ worth of podcasts), ludicrous amounts of alcohol wipes (to scrub your stubbornly ink-dyed hands), more Copic marker refills than you think you would ever need (so you don’t have to drive…

However, if a human has an unexpected encounter with one, it can result in an uncomfortable skin rash that can last from minutes to hours. Thankfully I found this…
Sunday Sketch: Holy Halitosis, Spiderman!
Caterpillars of the tobacco hornworm (Manduca sexta), as the name suggests, specialize on eating nicotine containing plants. Normally, nicotine is an effective plant defense against herbivores as it poisons various animals by interrupting neural mechanisms associated with muscle movement. Tobacco hornworms, however, can handle doses of nicotine that are lethal to herbivores that do not…
Field Frame Friday: PVC is marine mammal enrichment’s best friend.
This is what science looks like! That is if your science involves building enrichment puzzles for seals to help them learn how to forage for food! Enrichment and is a tool used to promote positive behaviors and provide cognitive stimulation to animals. This stimulus aims to encourage a species-typical “rock flipping” behavior in Hawaiian monk…
