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.

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

to Lucy Nash, who is commissioning editor for science at Oxford University

This month I’m joined by special guest James O’Hanlon from the Australian museum in Sydney for a deception and disguise special. James tells me about his PhD research on mantids that trick bees by mimicking flowers - or do they?! And we discuss a new paper showing that butterfly eyepsots might really be mimicking the eyes of a predator’s own predator. In the Scientific spark I talk to Marie Herbenstein, from Macquarie University in Sydney, who tells me that things might have not gone the way they have if she’d chosen a different research project!

This month I discover what black field crickets do when predatory lizards get too close. I find out how humans bond with

their canine chums. In the Scientific

spark I talk to Tristram Wyatt, from the University of Oxford, who tells me how

he became fascinated in all things pheromone-y.

This month, I discover that a preference for a particular colour of food can be heritable, and I also have a chat with Niels Dingemanse from the Max Planck Institute for Ornithology about how you test animal personality. In the Scientific spark, I talk to Shaun Killen, from the University of Glasgow, who tells me about his inspiration to become a scientist.

This month, I find out that penguins can’t tell the difference between savoury and sweet. I also chat with Sonia Van Wijk from The Université de Sherbrooke in Quebec, Canada, about what makes a male tree swallow attractive to a female who's on the look-out for more than one partner. And in the Scientific spark, I talk to social network whizz Damien Farine, from the University of Oxford, about his path into science.
