ABSTRACT Diving birds can spend several minutes underwater during pursuit-dive foraging. To find and capture prey, such as fish and squid, they probably need several senses in addition to vision. Cormorants, very efficient predators of fish, have unexpectedly low visual acuity underwater. So, underwater hearing may be an important sense, as for other diving animals. We measured auditory thresholds and eardrum vibrations in air and underwater of the great cormorant (Phalacrocorax carbo sinensis…

The audiogram was comparable to that of other birds of similar size, thereby indicating that puffins have fully functioning aerial hearing despite the constraints of their deep-diving, amphibious lifestyles.

Underwater hearing in sea ducks with applications for reducing gillnet bycatch through acoustic deterrence.

As diving foragers, sea ducks are vulnerable to underwater anthropogenic activity, including ships, underwater construction, seismic surveys and gillnet fisheries. Bycatch in gillnets is a

Pavlovian conditioning of gentoo penguins (Pygoscelis papua) to underwater sound

ABSTRACT Penguins are known to react to underwater noise, but it is unknown if they make use of sound cues while diving. We tested whether captive gentoo penguins (Pygoscelis papua) can pair

Great cormorants (Phalacrocorax carbo) can detect auditory cues while diving

In-air hearing in birds has been thoroughly investigated. Sound provides birds with auditory information for species and individual recognition from their complex vocalizations, as well as cues while

These data show sensitive in-air hearing, and supports concerns about coastal noise which could have clear ecologically relevant consequences.

Amphibious hearing in spotted seals (Phoca largha): underwater audiograms, aerial audiograms and critical ratio measurements

The hearing data reported herein are the first available for spotted seals and can inform best management practices for this vulnerable species in a changing Arctic.

In-air hearing of the great cormorant (Phalacrocorax carbo)

The great cormorant is more sensitive to in-air sounds than previously believed and its hearing abilities are comparable to several other species of birds of similar size.

Specialization for underwater hearing by the tympanic middle ear of the turtle, Trachemys scripta elegans

Turtles, like other amphibious animals, face a trade-off between terrestrial and aquatic hearing. We used laser vibrometry and auditory brainstem responses to measure their sensitivity to vibration

Amphibious hearing in ringed seals (Pusa hispida): underwater audiograms, aerial audiograms and critical ratio measurements

Psychophysical experiments with trained ringed seals show acute hearing abilities in both air and water, which are comparable to those of other phocid seals and considerably better than previously reported for this species.

Low-frequency amphibious hearing in pinnipeds: methods, measurements, noise, and ecology.

Comparisons of each subject's aerial and underwater thresholds revealed the sea lion is adapted to hear best in air; the harbor seal hears almost equally well in air and under water; and the elephant seal's auditory system is adapted for underwater functioning at the expense of aerial hearing sensitivity.

Comparative assessment of amphibious hearing in pinnipeds

Auditory sensitivity in pinnipeds is influenced by the need to balance efficient sound detection in two vastly different physical environments. Previous comparisons between aerial and underwater

Vision and Foraging in Cormorants: More like Herons than Hawks?

It is concluded that cormorants are not the aquatic equivalent of hawks, and their efficient hunting involves the use of specialised foraging techniques which employ brief short-distance pursuit and/or rapid neck extension to capture prey that is visually detected or flushed only at short range.
