This month, animal arithmetic from a research group in Italy who investigated how chickens order numbers – I put Naked Scientist Graihagh Jackson through her paces. Also in the episode, Leanne Grieves from McMaster University tells me what Smooth-billed anis do in response to different types of predators. And Niels Dingemanse, from the Max Planck Institute for Ornithology tells me about his Scientific Spark.

This month I meet some very polite deer who have a special way of asking for food. I discover why some plant nectars contain poisonous toxins. And in the scientific spark, I talk to Iain Couzin from the Max Planck Department of Collective Behaviour. Iain tells me what sparked his interest in becoming a scientist, and how, if his teachers had had their way, he might have been doing something entirely different.

Oct 17: Iain Couzin's Scientific Spark, why do deer in Japan bow, and why are some plant nectars bitter?

This month I find out that animals should be careful when choosing a mate, picking a partner that matches them in quality, else they might face an early grave! I discover that a mutation in a taste receptor gene has helped macaques in Japan to become thieves. And in the scientific spark, I talk to Kate Umbers from the University of Western Sydney, who works on a variety of topics, mainly related to understanding the mechanisms, functions and evolution of biological colouration. She tells me what sparked her interest in becoming a scientist.

This month I hear how a wildlife park in Yorkshire is providing the perfect retirement setting for an old polar bear. I discover that social insects make trips to natures pharmacy to fight infections. And in the scientific spark, I talk to Patricia Brekke from the Zoological Society of London, who tells me about her research on the endangered new Zealand bird the Hihi, and what inspired her to become a scientist.

This month I find out about sea ducks who enjoy a rather sophisticated fast food diet of mussels. I discover that horses horse around with lots of different facial expressions. And in the scientific spark, I talk to Johan Nilsson from the university of Lund, who researches the physiology and evolutionary ecology of birds.

In this episode I discover that some species of coral reef fish change colour, and they do this to grab a sneaky meal! I also find out how moths find flowers in the dark. And in the scientific spark I talk
