Antarctic Albatross Displays Shift In Breeding Habits
2012-04-30 08:34:58

A new study of the wandering albatross — one of the largest birds on Earth — has shown that some of the birds are breeding earlier in the season compared with 30 years ago. Reporting online this month (April) in the journal Oikos, a British team of scientists describe how they studied the breeding habits of the wandering albatross on the sub-Antarctic island of South Georgia. They have discovered that because some birds are now laying their eggs earlier, the laying date for the...

6.8 Million Birds Die Each Year At Communication Towers
2012-04-26 06:38:56

More than 6 million birds die every year as they migrate from the United States and Canada to Central and South America, according to a new study published Apr. 25 in the open access journal PLoS ONE. The birds are killed by the 84,000 communication towers that dot North America and can rise nearly 2,000 feet into the sky. "This is a tragedy that does not have to be," said lead author Travis Longcore of the University of Southern California. The taller the tower the greater the threat, the...

Ravens Remember Relationships They Had With Others
2012-04-19 11:49:38

In daily life we remember faces and voices of several known individuals. Similarly, mammals have been shown to remember calls and faces of known individuals after a number of years. Markus Boeckle and Thomas Bugnyar from the Department of Cognitive Biology of the University of Vienna show in their recent article, published in Current Biology, that ravens differentiate individuals based on familiarity. Additionally, they discovered that ravens memorize relationship valence and affiliation....

Bats Save Energy By Drawing In Wings On Upstroke
2012-04-12 04:15:23

[ Watch the Video ] Whether people are building a flying machine or nature is evolving one, there is pressure to optimize efficiency. A new analysis by biologists, physicists, and engineers at Brown University reveals the subtle but important degree to which that pressure has literally shaped the flapping wings of bats. The team's observations and calculations show that by flexing their wings inward to their bodies on the upstroke, bats use only 65 percent of the inertial energy they...

Ornithology
2013-10-09 12:32:30

Ornithology, a branch of zoology, is the study of birds. The term ornithology is derived from the ancient Greek words for bird and rationale or explanation. This study differs from other sciences because amateurs often take part in studies and because birds are commonly seen. It is thought that ornithology developed in the same manner than biology developed. Drawings from the Stone Age show the earliest interest in birds and the remains of over eighty bird species have been found at excavated...
