Remember the days when hummingbirds were regular visitors to our backyards, flitting around like nature’s little miracles? If you’ve noticed their sudden disappearance, you’re not alone.

Here are nine surprising reasons these tiny wonders might have vanished from your garden, and how you can coax them back.

1. Seasonal Migration

The main force behind changing bird migration is the seasonal fluctuation of food supplies, climate, predation, and competition for resources. Because hummingbirds rely heavily on nectar, it stands to reason that their migration patterns are connected to plant species that are in bloom.

2. Natural Food Sources Abound

Planting flowers and shrubs give hummingbirds more sources of food. Instead of depending on your feeder, they can find plenty of colorful, nectar-rich blooms and sources of insects.

3. Predator Presence

Praying mantis are often attracted to feeders initially by the presence of smaller flying pollinators—like bees or wasps. So keeping these flying insects away should reduce the chances of a praying mantis being drawn to a feeder, and keep hummingbirds safe.

4. Dirty Feeders

Dirty feeders are a deterrent to hummingbirds. Mold and mildew can make them sick, and nectar that is spoiled or ant-filled is going to make hummingbirds avoid your feeders.

Hummingbirds are very particular about their feeders and will leave a feeder that is too often dirty or empty. Leaving a dirty hummingbird feeder in your yard is a guaranteed way to send the hummingbirds you want to see to find somewhere else to eat.

If you can’t commit to regularly filling and washing your hummingbird feeders, it’s best to plant lots of nectar-producing flowers and let those do the work of attracting hummingbirds.

5. Competition From Other Birds

Larger birds may be crowding out the hummingbirds at your feeders. If you notice other species taking over, consider placing additional feeders in different locations.

This can help reduce competition and ensure your tiny visitors have a peaceful place to feed.

6. Lack of Shelter

Remember, too, that hummingbirds need more than just a meal to feel at home in your garden. They need places to perch and water to bathe in and cool themselves down in summer.

Where possible, you should include plenty of trees and shrubs in your space to provide hummingbirds, other birds, and other wildlife with shelter and habitat throughout the year. Plant some shrubs or small trees in your yard to provide shelter for the hummingbirds.

The birds will use these as perches and nesting sites. You can create a backyard oasis that attracts these fascinating creatures by following these simple tips.

7. Weather Changes

Finally, extreme weather can also be a threat to hummingbirds. Extreme heat or cold can kill these birds, and severe storms can damage their nests, destroy food sources, and throw them off their migration routes.

Additionally, weather events can affect when hummingbirds depart. They are unlikely to travel during a significant tropical storm, so the weather in Central America and the Gulf of Mexico can affect the arrival of hummingbirds to Michigan’s yards and gardens.

8. Lack of Consistent Food

If the hummingbirds return and the feeders are not out, they will be forced to look elsewhere for food. They must feed sometimes as often as every five minutes to keep up their amazing flight speed.

While planting nectar-rich flowers will attract neighborhood hummingbirds, you can further entice them by setting up feeders. Adding clean, well-maintained feeders to your yard ensures that visiting hummingbirds have a consistent food source, even if there aren’t a lot of blooming flowers nearby.

9. Changes in Habitat

Urban development or changes in the local environment can affect hummingbird populations. Loss of natural habitats may force them to relocate.

Supporting conservation efforts and creating a bird-friendly garden can help mitigate these impacts and encourage hummingbirds to return.
