According to a study by the UW, hummingbirds move their bills and tongues very quickly to drink a flower's nectar. Alejandro Rico-Guevara, assistant professor of biology at the UW and curator of birds at the UW Burke Museum, is quoted.

Whether its smartphones or sneakers, toys or tents, about 80% of commercial goods are transported to markets around the world using giant container ships. As global shipping routes grow to meet increasing demand, so too does the likelihood of fatal collisions with whale species whose ranges overlap with them. Anna Nisi, a postdoctoral scholar of biology at the UW, is interviewed.

Hummingbirds, among the smallest birds on the planet, flap their wings at as much as 80 beats a second. And scientists have been studying how they get enough nectar to satisfy that energy demand. Alejandro Rico-Guevara, assistant professor of biology at the UW and curator of birds at the UW Burke Museum, is quoted.

At first glance, hummingbird bills look like straws — long and thin, perfect for sipping nectar. But a new study reveals that this comparison is far from accurate. Alejandro Rico-Guevara, assistant professor of biology at the UW and curator of birds at the UW Burke Museum, is quoted.

Hummingbird bills — their long, thin beaks — look a little like drinking straws. But new research shows just how little water, or nectar, that comparison holds. University of Washington scientists have discovered that the hummingbird bill is surprisingly flexible.

"Imagine you are a blue whale swimming up the California coast, as you do every spring. You are searching for krill in the Santa Barbara Channel, a zone that teems with fish, kelp forests, seagrass beds and other undersea life, but also vibrates with noise from ship traffic. Suddenly, the noise gets louder," writes Anna Nisi, a postdoctoral scholar of biology at the UW.

Scientists eavesdropped on orcas and found ship sounds may hide fish from the endangered killer whales. Jennifer Tennessen, senior research scientist in biology at the UW Center for Ecosystem Sentinels, is quoted.

Ship strikes are a leading threat to large whales, with global shipping routes overlapping 92% of their habitats, a new study finds. But protecting whales in the most dangerous collision hotspots would require action over just 2.6% of the ocean’s surface, researchers conclude, potentially saving thousands of whales with minimal disruption to global trade. Briana Abrahms, assistant professor of biology at the UW, is quoted.

A new study led by the University of Washington has for the first time quantified the risk for whale-ship collisions worldwide for four geographically widespread ocean giants that are threatened by shipping: blue, fin, humpback and sperm whales. In a paper published online Nov. 21 in Science, researchers report that global shipping traffic overlaps with about 92% of these whale speciesâ ranges. Only about 7% of areas at highest risk for whale-ship collisions have any measures in place to protect whales from this threat. These measures include speed reductions, both mandatory and voluntary, for ships crossing waters that overlap with whale migration or feeding areas.

It’s not clear how the juvenile male ended up so far north, but experts suggest he was motivated by his appetite. Dee Boersma, professor of biology at the UW, is quoted.

A team led by scientists at the University of Washington and the University of Aberdeen attached tiny âbackpackâ trackers to hummingbirds in the Colombian Andes to learn more about their movements. As they report in a paper published Oct. 10 in the journal Ecology and Evolution, the tracking system will aid conservation efforts in this region by revealing the previously hidden movements of hummingbirds and other small animals.

Standing on the beach in the small town of Denmark in Western Australia on Friday afternoon was a male emperor penguin, about 2,100 miles from where one might expect to find it, in Antarctica. Dee Boersma, professor of biology at the UW, is quoted.

As Earth faces unprecedented climate change, a look into the planetâs deep past may provide vital insights into what may lie ahead. But knowledge of the natural world millions of years ago is fragmented. A 15-year study of a site in Bolivia by a joint U.S.-Bolivia team has provided a comprehensive view of an ancient ecosystem when Earth was much warmer than it is today, and changed how we look at the Andes.

Across the animal kingdom, models have vastly underestimated the energy costs of reproduction. Lauren Buckley, professor of biology at the UW, is quoted.
