The ‘Second Wave’ Hummingbird Arrival: Why Females Show Up 10 Days After Males

Birdwatchers are always excited about Spring, hummingbirds are the first arrivals and signal the start of spring activities. The first hummingbirds are always males displaying bright colored throat feathers. The males arrive first and about 10 days later, the females arrive.

Hummingbirds are super territorial, so the earlier a male arrives, the better his chance of getting a good spot. He will spend all day aggressively defending this patch of flowers, or your favorite feeder, against other males. By establishing this territory first, he demonstrates to the females that he can offer an all-you-can-eat buffet with a safe surrounding.

The Second Wave: Why Females Wait

Female hummingbirds approach their northern trek a bit differently than their male counterparts, arriving a week to 10 days later. This brilliant delayed strategy is based on survival and conservation of energy.

Migrating takes a lot of energy, however, females have a great deal of work to do after the journey. Upon arrival to a new destination, females must build a nest, sit on the eggs to incubate them, and subsequently feed the chicks. By delaying departure a little bit longer, females create spring weather to warm up a little more. Additionally, their delay helps the native vegetation to mature.

Preparing for the Females

Use the 10-day gap between the arrival of the males and females to prepare your yard for the bird visitors. Since bully males are known for being aggressive, they often monopolize bird feeders and will guard them. A male will even sit in a nearby tree and dive bomb any females that try to access the feeder.

To guarantee the incoming females receive the energy required, adhere to this straightforward preparation checklist:

Supporting the Nesting Season

As soon as the females come and mate, they will start searching for nesting materials. You can assist them by leaving your yard as natural as you can. If there are spider webs in your garden, just leave them be. Female hummingbirds use the sticky silk from webs to hold their nests together, allowing the nests to stretch as the babies grow. sticky spider silk to bind their tiny nests together

You should also use an understanding of nature instead of chemical pesticides in your yard. Hummingbirds need to eat a large number of small insects (like gnats and mosquitoes) to get the adequate protein needed to raise their babies, so a mother hummingbird nest in your yard is exactly the type of healthy bug garden all nesting hummingbirds need.
