My students and I have decided that if this project gets funded we will produce a documentary video for all the backers on how hummingbirds manage their body temperature while hovering in warm temperatures. We will address how hummingbirds might respond to warming temperatures resulting from climate change.

Do hummingbirds use cool perches so they can fly in the heat?
View comment
Thanks Amanda! I have been taking undergraduates to SWRS for 30 years, and every one of them looks back on their time in the Chiricahua Mountains fondly. Crowd funding for research support is not the typical way the undergraduates are supported, but the foundation that typically pays the expenses has had a couple bad years. This funding really makes a difference because it means they can have a great experience without having to excessively pinch pennies. Thanks again for your support!
