When it is over 90 degrees Hummingbirds struggle with overheating just like we do. They seldom die of heat exhaustion itself, but from their inability to maintain their eating requirements. Hummers need to eat every 10-15 minutes to keep up with their extremely high metabolism.
The heat makes them seek out shady areas to avoid direct sunlight which quickly raises their body temperature. However, most of their food source is in the sun, and they overheat while searching for nectar and are forced to return to the shade before getting full.
The plants hummingbird’s feed on are also negatively impacted by the heat. Many will produce significantly fewer flowers in hot weather which equals less nectar for the hummers. They are forced to spend more time looking for food which increases their chances of overheating.
Many natural water sources also disappear. Decreasing nectar and water combined can lead to a hummingbird’s death.
This summer has been a scorcher with record high temperatures. Please help our hummingbird population by hanging a feeder and maintaining it properly. Not only will you help save them but you will enjoy seeing them zoom around.
