An understanding of diet selection in animals requires knowledge of not only what animals eat in relation to what is available, but also how they perceive the foods available to them. Birds use auditory, visual, olfactory and possibly vibrotactile cues to find prey, but vision is the predominant mode of prey detection. In a series of controlled experiments in an aviary, four American robins, Turdus migratoriusfound buried mealworms in the absence of visual, olfactory and vibrotactile cues…

Predatory attacks by prey-naïve subjects directed to video cues when only visual prey stimuli were available demonstrated that snakes can identify prey visually without prior experience.

BARK-FORAGERS MAY USE ARTIFICIALLY CREATED HOLES IN TREES AS A FORAGING CUE

Little is known about cues used by insectivorous bark-foraging birds to locate prey. Because vision is thought to be the primary sensory system used by many avifauna to perceive the environment, we

Sunbirds increase foraging success by using color as a cue for nectar quality

It is demonstrated that sunbirds forage more efficiently with cues, which may lead to increased fitness and a reduction in foraging costs when cues allow for location of rewarding feeders.

Avian predation on a parasitic fly of cervids during winter: can host-related cues increase the predation risk?

It is demonstrated that pupae are predated by a number of tit species, and the ability of tits to use this host-derived cue seems to be dependent on the prevalence of L. cervi and the period of invasion history, which suggests that it may be a learned behavioural response.

Remote touch prey-detection by Madagascar crested ibises Lophotibis cristata urschi

The ibises were reliant on remote touch for prey detection – the first time this sensory system has been demonstrated for this group of birds, while hearing or chemical senses/olfaction did not appear to aid in prey detection.

Overwintering Coots Fulica atra atra were observed in January 2006, in Keoladeo National Park, India. Here they fed on aquatic plants, which they exploited in strictlymaintained dense flotillas;

Sensory Mechanisms and Environmental Clues Used by the American Robin in Locating Earthworms

The familiar sight of the American Robin (Turdus migratorius) foraging for earthworms on a lawn has not prompted a detailed investigation of the sensory mechanisms and environmental clues employed by

Locatable and Nonlocatable Acoustic Signals for Barn Owls

Physical parameters of sound that affect acoustic location in the barn owl were studied and differences in locatability between the two classes of signals are not due to the reasons given by Marler for predators in general.

This chapter discusses the evolution of hearing in the Mammals and the structure and function of the Avian Auditory System, as well as the nonlinear properties of the Peripheral Auditory system of Anurans.

Variation in singing behaviour between males can involve fixed differences such as the song type composition of repertoires, as well as more flexible effects such as matched counter‐singing, differences in bout length and changes in strophe length.
