Less Diversity Found In Bird Species Of 125M Years Ago
2014-05-28 11:10:57

Brett Smith for redOrbit.com - Your Universe Online While the typical American wetland hosts a range of birds with different physiologies and behaviors, bird diversity in prehistoric times was significantly lower, according to a new study published in the journal Proceedings of the Royal Society B. "There were no swans, no swallows, no herons, nothing like that. They were pretty much all between a sparrow and a crow," said study author Jonathan Mitchell, an evolutionary biologist at the...

Evolution Of Smaller Dinosaurs Helped Their Lineage Survive As Birds
2014-05-07 09:53:08

Brett Smith for redOrbit.com - Your Universe Online While dinosaurs may have disappeared from the face of the Earth, their lineage has survived in the form of birds and new research published in the journal PLOS Biology has found that both dinosaurs and birds evolved into smaller and smaller sizes – potentially contributing to their success. “Dinosaurs aren't extinct; there are about 10,000 species alive today in the form of birds,” said study author Roger Benson, a paleobiologist...

asteroid impact
2014-04-10 08:39:56

Brett Smith for redOrbit.com - Your Universe Online Earth was irrevocably changed when the dinosaurs were wiped out about 65 million years ago by a massive asteroid, but a much bigger asteroid that struck the Earth nearly 3.3 billion years ago is thought to have shaped parts of Africa. Now, a new study published in the journal Geochemistry, Geophysics, Geosystems has outlined the details surrounding that massive impact, such as the creation of a crater about 300 miles across and...

Researchers used brown and black chicken feathers for their study
2014-03-06 07:01:57

April Flowers for redOrbit.com - Your Universe Online It has been proposed by paleontologists who study fossilized feathers that the shapes of certain microscopic structures found inside the feathers might tell us the color of the ancient birds. If these structures are melanosomes, that could be true. A new study, led by North Carolina State University, however, demonstrates that it is not yet possible to tell if the structures are melanosomes, or remnants of ancient bacteria. Found...

Swimming Birds Evolved Rudder-like Tail To Dive For Food
2014-02-27 15:43:42

PLOS The convergent evolution of tail shapes in diving birds may be driven by foraging style, according to a paper published in PLOS ONE on February 26, 2014 by Ryan Felice and Patrick O'Connor from Ohio University. Birds use their wings and specialized tail to maneuver through the air while flying. It turns out that the purpose of a bird's tail may have also aided in their diversification by allowing them to use a greater variety of foraging strategies. To better understand the...

Microraptor Paraves Fossil
2014-02-24 05:41:20

University of Bristol The key characteristics of birds which allow them to fly – their wings and their small size – arose much earlier than previously thought, according to new research from the Universities of Bristol and Sheffield into the Paraves, the first birds and their closest dinosaurian relatives which lived 160 to 120 million years ago. Mark Puttick and colleagues investigated the rates of evolution of the two key characteristics that preceded flight: body size and...

Revision To Rules To Decipher Color In Dinosaurs Suggests Connection Between Color And Physiology
2014-02-13 12:36:46

University of Texas at Austin New research that revises the rules allowing scientists to decipher color in dinosaurs may also provide a tool for understanding the evolutionary emergence of flight and changes in dinosaur physiology prior to its origin. In a survey comparing the hair, skin, fuzz and feathers of living terrestrial vertebrates and fossil specimens, a research team from The University of Texas at Austin, the University of Akron, the China University of Geosciences and four...

Active Nightlife Of Birds Driven By Desire To Reproduce
2014-01-23 10:04:09

University of Illinois College of Agricultural, Consumer and Environmental Sciences For a non-nocturnal bird, the yellow-breasted chat spends a significant amount of time visiting other birds' territories during the night. A University of Illinois researcher who was studying birds' movement during the day noticed that males were active almost every night, while the females were active at night but particularly during the window of time when they were fertile. "We were studying the...

Bird-B-Gone received excellent remarks from the DPR as a four hour Continuing Education (CE) credit in Bird Control training. Irvine, California (PRWEB) January 15, 2014 Bird-B-Gone University, a bird control training course offered by Bird-B-Gone, was recently audited by the Department of Pesticide Regulation. The course covers many things commercial...

Giants Of Earth's History Still Pose A Wealth Of Riddles
2014-01-14 10:32:20

Johannes Gutenberg Universitaet Mainz Sauropods, the largest land animals in Earth's history, are still mightily puzzling the scientists. These plant-eating dinosaurs with their long necks and small heads could reach a height of 10 meters or more and dominated all other land vertebrates in terms of size. They could weigh up to 80 tons, more than any other known land vertebrate. One question that has been intensely debated is how these giants of the animal kingdom regulated their own body...

John Harold Ostrom (February 18, 1928 – July 16, 2005) was an American Paleontologist who was greatly influential in the revival of scientific research on Dinosaurs. He is best known for demonstrating that Dinosaurs were less like contemporary reptiles but more closely related to large, flightless birds like the ostrich – a theory that holds its ground in the paleontological community to this day. John Ostrom was born and raised in Schenectady, New York. His father was a physician, and...

Robert Thomas Bakker (born March 24, 1945) is an American Paleontologist known for his contribution to the “Dinosaur Renaissance” and his support of his mentor Ostrom’s theory that some dinosaurs were warm-blooded. He specializes in the ecological context and behavior of dinosaurs. Bakker was born in Bergen County, New Jersey. As a young boy, he developed an interest in dinosaurs following his first trip to the dinosaur exhibit at the American Museum of Natural History – he was...

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...
