Sunbirds use a feeding trick that has never been seen before
A hummingbird darts up to a flower, slips in its long, thin beak and drinks. The whole visit lasts a fraction of a second, and for years scientists assumed the bird simply sucked the sweet liquid up and swallowed. Alejandro Rico-Guevara, associate professor of biology at the UW and curator of birds at the UW Burke Museum, is mentioned. -

Another mammal discovered that lived alongside dinosaurs
The history of life on Earth often feels like a story about giants. Huge dinosaurs, powerful predators and massive plant-eaters fill our imagination. But that is only part of the picture. Gregory Wilson Mantilla, professor of biology at the UW and curator of vertebrate paleontology at the UW Burke Museum, is quoted. -
Tiny fossil may have just rewritten the origin story of weasels
A single fossil jaw is forcing scientists to rethink the timeline of one of natures most agile hunters. Found in Spain, the tiny bone suggests that the ancestors of modern weasels were already on the move more than six million years ago far earlier than expected. Chris Law, a principal research scientist of biology at the UW and an affiliate curator at the UW Burke Museum of Natural History and Culture, is quoted. -
April research highlights: Sunbird tongues, Seattle fault, inbound asteroids, more
Explore recent research from the University of Washington: how sunbirds sip nectar through straw-like tongues, why the Seattle Fault might not pose as great a risk as previously thought, how to gauge landslide dam risk in the PNW, what marine microbes use for making meals and when the Simonyi Survey Telescope at the NSF-DOE Rubin Observatory will spot small inbound asteroids.

Researchers discover the fossil of a new hamster-sized mammal that lived alongside dinosaurs on the Pacific Coast
A research team led by the UW has identified a new species of an ancient rodent-like creature. The new species, named Cimolodon desosai, was about the size of a golden hamster, the researchers said. It likely scampered on the ground and in the trees and ate fruits and insects.

Watch these birds use their tongues to suck up nectar
New research published in Current Biology reveals sunbirds use their long tongues as a kind of makeshift straw to hoover up nectar in flowersthe first vertebrates known to do so. Alejandro Rico-Guevara, associate professor of biology at the UW and curator of birds at the UW Burke Museum, is mentioned. -
A fossil of a new carnivoran species effectively doubles the evolutionary history of the weasel family
A new study doubles the evolutionary history of the weasel family. Researchers, including Chris Law, a UW principal research scientist in the biology department, have determined that a fossil that was discovered in Spain belongs to a new species dating back to around 6.5 million years ago. This new species was likely similar in size to the smallest living weasel species today, the least weasel.

Ancient crocodile Sonselasuchus cedrus walked on four legs as a baby before switching to two
Scientists have unearthed a "peculiar" ancient crocodile that walked on two legs after beginning its life on four. Named Sonselasuchus cedrus, the creature roamed the Earth during the Late Triassic period, approximately 225 to 201 million years ago. Elliott Armour Smith, graduate student of biology at the UW, is quoted.

Ancient 'weirdo' reptile graduated from four legs to two in adolescence
An early relative of crocodiles spent its juvenile years walking on all fours, then stood up on two legs as an adult. Its arm and leg bones grew at different rates to enable this transition. Elliott Armour Smith, graduate student of biology at the UW, and Christian Sidor, curator of vertebrate paleontology at the Burke Museum and professor of biology at the UW, are quoted.

This ancient reptile started life on all fours then it stood upright and started walking on two legs instead
Roughly 215 million years ago, an unusual-looking reptile traipsed around what is now Arizona. About the size of a poodle, the creature had large eye sockets, a toothless beak and short arms. During the early part of its life, the animal seems to have walked around on all fours. But as it grew, it stood upright and began striding around on two legs instead. Elliott Armour Smith, graduate student of biology at the UW, and Christian Sidor, curator of vertebrate paleontology at the Burke Museum and professor of biology at the UW, are quoted.
