Hummingbirds are some of the smallest birds in the world, yet they can migrate more than 5,600 miles (9,000 km) a year. To do so, they need energy from the nectar of flowers. But the location of wildflowers on their journeys is changing due to climate change and land use. So sometimes they have to go into short hibernation periods overnight - called torpor - to conserve energy for the next day's journey. This month, researchers from the University of New Mexico said they've found specific fat levels and fat reserves the hummingbirds need to go into hibernation and then resume their journeys in the morning. • Read the full article: • https://earthsky.org/earth/hummingbir... • Producer: Cristina Ortiz, EarthSky's defender of animals • https://earthsky.org/author/cristinal... • #earthsky #hummingbirds #birds #nectar #flowers #migration #tiny #animals #nature
