The Great Migration: Why Do They Leave?

  • Survival Instincts: The basic instinct to survive is the heart of their migration. As Pennsylvania’s temperatures drop, the availability of food sources, primarily nectar, diminishes. Migrating allows hummingbirds to find warmer climates with abundant food.
  • Reproductive Needs: Migration also plays a crucial role in their breeding cycle. They can find optimal conditions for nesting and raising their young by moving to specific regions.

Pennsylvania’s Hummingbird Calendar: Key Departure Dates

  • Early Departures: Breeding males, being territorial, often leave first. In Pennsylvania, they may start their journey as early as August.
  • Peak Migration: The majority of hummingbirds begin their migration in late September or early October. This is when you’ll notice a significant decrease in their numbers around feeders and gardens.
  • Stragglers: Some young birds or late breeders might linger a bit longer, but by the end of October, most have embarked on their journey south.

The Journey South: Where Do They Go?

Hummingbirds don’t just randomly head south. Their destinations are often specific wintering grounds in Central America. Some species, like the Ruby-throated Hummingbird, might travel as far as Panama, covering thousands of miles.

Supporting Hummingbird Journey - How You Can Help

Supporting Hummingbird Journey: How You Can Help

As they prepare for their demanding migratory journey, there are several ways we can assist them, ensuring they have the best chance of reaching their destination safely.

Maintain Feeders:

  • Consistent Supply: Even as the season changes, it’s essential to keep your feeders full. As flowers begin to wane, feeders become a critical source of nutrition for these tiny travellers.
  • Cleanliness: Regularly cleaning your feeders prevents the growth of mould and bacteria, which can be harmful to hummingbird birds.
  • Right Mixture: When preparing sugar water for feeders, use a ratio of 1 part sugar to 4 parts water. Avoid using honey or artificial sweeteners, as they can be harmful.

Provide Water:

  • Shallow Sources: Hummingbirds prefer shallow water sources. A shallow dish or a bird bath with a gentle slope is ideal. This allows them to wade in without the risk of submersion.
  • Clean Water: Ensure the water is fresh and clean. Change it regularly to prevent the growth of algae and mosquitoes.
  • Bathing Spots: While they primarily use water for drinking, hummingbirds also enjoy bathing to clean their feathers. Adding a few rocks or pebbles to the water source can give them a perfect perch for this activity.
Hummingbird Behaviour Before Migration

Signs of the Impending Journey: Hummingbird Behaviour Before Migration

Before embarking on their long journey, hummingbirds exhibit certain behaviours that signal their impending departure. They often become more territorial around feeders, consuming large amounts of nectar to build up fat reserves. 

This hectic feeding helps them store energy for the long flight ahead. You might also notice them checking out the same spots repeatedly, a behaviour known as “zoning”, which helps them memorise locations for their return.

The Duration of the Flight: How Long is Their Journey?

The length of the hummingbird’s migration journey varies depending on the species and the specific route they take. For many, the journey from Pennsylvania to Central America can span anywhere from a week to several weeks. 

Factors affecting the duration include weather conditions, availability of food sources along the route, and the bird’s overall health and stamina.

What Do Hummingbirds Face During Migration

What Do Hummingbirds Face During Migration?

Migration is no small feat for these tiny birds. Along their journey, hummingbirds face numerous challenges:

  • Predation: Birds of prey, like hawks, are a constant threat.
  • Weather: Sudden storms or strong winds can be difficult.
  • Exhaustion: The non-stop flight, especially over the Gulf of Mexico for some, demands immense energy.
  • Food Scarcity: Finding enough nectar sources along the way is crucial for survival.

Do Any Hummingbirds Stay Behind?

While the majority of hummingbirds migrate south for the winter, there are occasional reports of individuals overwintering in Pennsylvania. These instances are rare and often involve species not typically found in the state, like the Rufous Hummingbird. 

It’s crucial for residents who spot hummingbirds during the colder months to provide food and shelter, as natural nectar sources are scarce.

When Will Hummingbirds Be Back in Pennsylvania

The Return: When Do Hummingbirds Return to Pennsylvania?

Hummingbirds typically return to Pennsylvania in spring, around April. Their migration north is motivated by breeding requirements and the availability of food.

Following their migration pattern, the Ruby-throated Hummingbird is often the first species to make its appearance in Pennsylvania during the spring. This Hummingbird species is primarily driven back by the attraction of breeding opportunities and the blossoming of early nectar-rich flowers in the region.

Final Thoughts

As the seasons change and the colourful Pennsylvania landscape transforms, the departure of our beloved hummingbirds marks a touching moment in the natural calendar. 

These tiny birds exhibit remarkable resilience, travelling great distances with precision and determination.

Their migration inspires amazement and may even evoke feelings of sadness as we watch these stunning birds depart.

So, as you gaze into the skies, watching the last of these beautiful birds heading south, one of the greatest gifts you can offer is to prepare for their return.
