Do Hummingbirds Actually Sleep?


When hummingbirds spend more energy than they consume, they go into a deep hypothermia (torpor) which, unlike restful sleep, can have physiological consequences. Professor Donald R. Powers and Isabelle Cisneros, an undergraduate researcher at George Fox University, are collaborating to understand if hummingbirds can also maintain a more shallow torpor that would conserve energy without reducing the body temperature so much that it prevents restoration. 

When studying torpid and non-torpid hummingbirds in Arizona and Ecuador, the team found that in both locations some hummingbirds had intermediate metabolic rates in between torpor, which suggests there may be a smaller body temperature reduction and a shallow torpor. While they've received support from traditional grants, they haven't received the student funding that Isabelle needs to work at a field site in Arizona. Once there, she and Professor Powers will measure body temperature regulations in the hummingbird's natural habitat. If their predictions are correct,  their research could transform what we know about hummingbird physiology.

A Prescription for Health and Fitness Based on Your Genes


In 2014, four researchers campaigned to explore the connections between exercise programs and a person's genes, and area of study known as exercise genomics. Specifically, they sought to explore if genes played a role in how patients with hypertension respond to exercise. Their new research angle was formed after their initial study in 2001, where they found that the genes that seemed the most relevant to exercise and hypertension were unknown, making them hard to analyze.

As technology progressed, so did their study, and they decided to use deep gene sequencing, which could identify more genes, to study 90 adults with high blood pressure. In their exercise study, they measured the effects of exercise on the adults' hypertension and analyzed the genes their blood samples. A couple of years later, they arrived at some interesting results that associate genetic differences with post-exercise hypotension in African Americans. This puts them one step closer to being able to pinpoint the correct exercise treatments for patients with high blood pressure.

Dear Peter,
Twice a year, billions of American birds lift up and migrate to and from their breeding and wintering homes. But these days, they find fewer rest stops and places to catch a bite along the way. Falling numbers of birds tell the story: Migratory birds are in trouble. Make a donation to ABC today to help birds lift off and travel safely.
We aim to make this year the beginning of safer travel for migratory birds. We are already working to secure safe habitats for forest, grassland, and coastal birds. But given the volume of birds on the move, the great distances to cover, and the growing number of real-time threats, we must greatly accelerate our on-the-ground actions if we are going to save the greatest animal migration on Earth.
We need to raise $1 million for migratory birds by the end of the year. All donations made by December 31 will be matched! We need your help as never before. Please donate today.
Travel is challenging whether you are a bird or a person. Wishing you safe travels this Thanksgiving, and our sincere thanks for giving a lift to birds and to American Bird Conservancy.
Best regards,

P.S. Giving Tuesday is five days away! We hope you think of ABC on Tuesday, November 29 and encourage your fellow conservationists to make us part of their charitable giving this year.
Visit us at abcbirds.org, or on Facebook (@AmericanBirdConserve) and Twitter (@abcbirds1) to get involved this #GivingTuesday.

Fwd: Take Action, New York: Say No to Gauntlet of Turbines on Lake Ontario

When it comes to wind energy and wildlife, siting is everything. Right now, a disaster is in the making on the south shore of Lake Ontario in New York, where – if plans proceed – millions of birds will be threatened by a gauntlet of up to 71 turbines, each up to 620 feet tall.

Recent studies show that the routes used by migrating birds for millennia will put them squarely in the danger zone of these turbines. Many of the species that will be put at risk are becoming rare, like Rusty Blackbird and Short-eared Owl. Can we risk putting deadly obstacles in their way?

Renewable energy is important in the fight against climate change, but proper siting is essential to avoid needless mortality of wildlife. Tell your government officials that the shoreline of Lake Ontario is NOT the place for large-scale, industrial wind energy. Thank you!
