Noise pollution is one of the leading environmental health risks in humans. In zebra finches, noise affects their health and the growth of their offspring: Researchers at the Max Planck Institute for Ornithology in Seewiesen found that traffic noise suppresses normal glucocorticoid profiles in the blood, probably to prevent negative effects of chronically elevated levels on the organism. In addition, the young chicks of noise-exposed parents were smaller than chicks from quiet nests. more

A new joint research centre of the Max Planck Society and Yale University will promote the study and protection of biodiversity more

Bats do not only use the information of their echolocation calls for foraging but may also simultaneously analyse acoustic signals from their potential prey. Researchers of the Max Planck Institute for Ornithology in Seewiesen found that Greater Horseshoe bats use such combined acoustic stimuli to considerably extend the limited reach of their echolocation calls. more

In populations with an unbalanced adult sex ratio, male plovers take care of the young more

The colour of bands attached to the legs of birds for individual identification does not have an effect on the birds’ behaviour, physiology, life-history or fitness. This result of a study from the Max Planck Institute for Ornithology in Seewiesen contradicts long established text-book “knowledge” and questions whether ornaments play a major role in mate choice of monogamous species. more

In the evolutionary arms race between bats and their insect prey, some moths have developed ears to detect echolocating bats and avoid being caught. Conversely, barbastelle bats are known to counter moth hearing by using quiet, 'stealthy' calls to search for prey in the dark. Recording the hunting behaviour of this intriguing species, researchers have now found that barbastelle bats sneak up on unsuspecting moths by gradually emitting even fainter calls as they come closer. more

Parents need to synchronize the care for their offspring. This leads to extreme and unexpected diversity in how parents attend their nest in shorebirds. Some pairs switched duties 20 times a day, while in others one parent sat on the nest for up to 50 hours. The key factor underlying this variation is risk of predation, not risk of starvation. more
