Hummingbirds are resilient birds, but extreme heat can put them at serious risk of dehydration, overheating, and exhaustion. As temperatures rise, these tiny birds struggle to find cool shelter, fresh nectar, and water sources. Here’s how you can help hummingbirds stay safe and hydrated during extremely hot weather.
1. Keep Nectar Fresh and Cool
Why It’s Important:
High temperatures cause hummingbird nectar to spoil quickly, leading to fermentation and harmful bacteria growth. Spoiled nectar can make hummingbirds sick or dehydrated.
How to Help:
- Change nectar daily when temperatures exceed 85°F.
- Keep feeders in shaded areas to slow fermentation.
- Use glass feeders instead of plastic, as they retain cool nectar longer.
- Rinse feeders thoroughly with warm water (no soap) before refilling.
2. Provide Shade and Shelter
Why It’s Important:
Hummingbirds lose energy quickly in extreme heat and need cool resting spots to recover.
How to Help:
- Place feeders near trees, shrubs, or covered porches to provide shaded feeding areas.
- Hang a sunshade or umbrella near feeders in open areas.
- Encourage natural shelter by planting flowering trees and dense shrubs.
3. Offer a Water Source
Why It’s Important:
Hummingbirds get moisture from nectar, but in extreme heat, they need extra hydration. Unlike other birds, they rarely visit deep birdbaths.
How to Help:
- Use a shallow birdbath with gently moving water.
- Add a fine mist sprayer or dripper, as hummingbirds love flying through mist to cool off.
- Place smooth stones in a birdbath to create a safe perch for drinking.
- Keep water sources in the shade to prevent overheating.
4. Plant Heat-Tolerant Flowers for Extra Nectar
Why It’s Important:
Extreme heat can reduce flower nectar production, making it harder for hummingbirds to find food.
How to Help:
- Plant heat-resistant, nectar-rich flowers, such as:
- Trumpet Vine
- Salvia
- Bee Balm
- Hummingbird Mint (Agastache)
- Water flowering plants early in the morning or late in the evening to keep them healthy.
5. Reduce Reflective Surfaces
Why It’s Important:
Bright, reflective surfaces increase heat and can confuse or disorient hummingbirds.
How to Help:
- Move feeders away from metal railings or glass windows that reflect sunlight.
- Use dull-colored or wooden feeder mounts to reduce glare.
- Apply window decals to prevent accidental collisions.
Extreme heat can be dangerous for hummingbirds, but with simple steps like providing fresh nectar, shade, water sources, and nectar-rich plants, you can help them survive and thrive during hot weather. Small changes can make a big difference in keeping these beautiful birds cool, hydrated, and safe.
FAQ’s
How does extreme heat affect hummingbirds?
Extreme heat can cause dehydration, overheating, and exhaustion in hummingbirds, making it harder for them to find fresh nectar and water.
How often should I change hummingbird nectar in hot weather?
In temperatures above 85°F, nectar should be changed daily to prevent fermentation and bacterial growth.
Do hummingbirds need water in hot weather?
Yes, hummingbirds need extra hydration during extreme heat. Providing a shallow birdbath, mist sprayer, or dripping water source can help.
Where should I place hummingbird feeders in summer?
Place feeders in shaded areas, near trees or covered porches, to keep nectar cool and provide shelter from the sun.
What flowers provide nectar for hummingbirds in hot weather?
Heat-tolerant flowers like trumpet vine, salvia, bee balm, and hummingbird mint (Agastache) provide essential nectar during summer.
