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

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...

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...

Mapping The Dinosaur-Killing Yucatan Peninsula Asteroid Impact Site
2013-12-10 06:29:28

April Flowers for redOrbit.com - Your Universe Online An asteroid or comet crashed into a shallow sea near what is now the Yucatan Peninsula of Mexico approximately 65 million years ago. A firestorm and global dust cloud resulted, causing the extinction of many land plants and large animals, including most of the dinosaurs. Researchers from the Monterey Bay Aquarium Research Institute (MBARI) presented evidence this week at a meeting of the American Geophysical Union (AGU) that remnants...

Fossilized Toe Prints Identified As Belonging To Large Ancient Bird
2013-10-28 13:20:31

Lee Rannals for redOrbit.com - Your Universe Online Scientists, publishing a paper in the journal Palaeontology, say two fossilized footprints found in Australia are most likely the oldest known bird tracks in the country. The researchers said the thin-toed tracks in fluvial sandstone were most likely made by two individual birds that were the size of a great egret or a small heron. These ancient birds would have lived during the Early Cretaceous period. "These tracks are evidence...

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...
