Anti-predator behaviour in giant clams and paternal provisioning in house wrens, denning behaviour in brown bears, behavioural motivation tests in rainbow trout, predatory strategy of a venomous snake, and detection dog surveys for cheetahs.

Leadership in animal groups, how host species determines egg size in the Oriental cuckoo, how a twig-masquerading spider is seen by predators, how signalling in urine-marking domestic dogs could be dishonest and how innate behavioural traits help a lizard to adapt to an urban environment.

Parental care and begging behaviour in poison frogs, egg attendance in cave-dwelling harvestmen, how Atlantic salmon behaviour protects them from external parasites, and an experiment on foraging success in pit-building antlions.

In this episode, we are told how bird collisions with vehicles may be affected by experience, we will learn about the brain of tarantulas and whether they show left-right asymmetry, and we will hear about baiting camera traps in the Amazon.

In this special 50th anniversary issue, estimating the maximum size of giant squids and 3D modelling of lion paws and tracks, colour adaptations in a blue-tailed lizard and how human food resources affect life history strategies in brown bears.

In this episode, how butterflies appear to the eyes of their predators, how bio-logging technology allows us to analyse animal behaviour, and how ants protect seedlings from pests.

In this episode, the mystery of the ‘dead bird’ posture in dinosaur fossils, how an animal’s locomotor performance can vary between different habitats and substrates, and how lions can influence the foraging strategies of spotted hyaenas.

In this episode, we will hear about a cannibalistic salamander that lives in caves, we will learn how to mitigate conflicts between reintroduced lions and the local people, and we are told about nest site selection behaviour in peregrine falcons.

In this episode, we will hear about how European starlings colonised North America, how the burrow structure of rabbits change as they move from the countryside into cities, and why polar bears have smelly feet!.
