Wildlife Experts Advise on Hummingbird Feeders This Fall

Hummingbirds are a beloved sight for many, but as autumn approaches, the question arises: should you take down your hummingbird feeder in September? Wildlife experts offer insights into the migratory patterns of these fascinating birds and the best practices for feeder maintenance during this transitional season.

To understand the timing for removing feeders, it’s important to consider the migratory behavior of different hummingbird species. According to Maria Kincaid, an ornithology research specialist at FeatherSnap, the migration schedule varies based on geographical location. For instance, the northernmost breeding populations of species such as Ruby-Throated Hummingbirds begin their migration as early as mid-August, with peak activity occurring in September and October.

Understanding Hummingbird Migration

Most hummingbirds in North America migrate, breeding in the United States and Canada before wintering in Central and South America. Kincaid explains that while some species, like Anna’s hummingbirds found in California and parts of Washington and Oregon, migrate elevationally rather than over long distances, the majority travel significant distances southward.

For those wondering when to take down their feeders, Kincaid advises that the optimal time aligns with local migration patterns. “The further north you are, the earlier you should take down your feeders,” she notes. To stay informed about local migration trends, Dan DeBaun, a bird blogger at Dan’s Birds Bites, recommends consulting local resources, such as state departments of natural resources or range maps provided by the Cornell Laboratory of Ornithology.

The Impact of Leaving Feeders Up

A common concern among bird enthusiasts is whether keeping feeders up during migration might discourage hummingbirds from flying south. DeBaun reassures that this is not the case. “Migration is instinctual and determined by the amount of daylight,” he explains. As days shorten, hummingbirds naturally become restless and begin their journey south, regardless of the feeders’ presence.

Interestingly, leaving feeders out can actually assist the birds during this critical time. Kincaid describes a behavior known as hyperphagia, where hummingbirds consume large amounts of nectar and insects to build fat reserves before migration. This feeding frenzy can nearly double their body weight, providing essential energy for their long journey. Keeping feeders available can support these preparations, especially as migrating birds stop to refuel.

While it is beneficial to leave feeders out, maintenance remains crucial. Kincaid emphasizes that fresh nectar is essential, and those less active in their yards during fall should periodically check their feeders. “Regular cleaning and refilling is just as important this time of year as it is when breeding birds are around,” she advises.

As temperatures drop, Kincaid suggests caution for those in colder regions. Leaving nectar in feeders during freezing conditions can damage the feeder and lead to moldy or contaminated liquid, which can pose health risks to the birds. If you live in an area subject to winter conditions, it is prudent to remove feeders when cold temperatures are expected.

In summary, understanding the migratory habits of hummingbirds and properly maintaining feeders can enhance the experience of observing these remarkable creatures. By taking care of feeders and being mindful of migration patterns, bird enthusiasts can contribute positively to the welfare of hummingbirds during their seasonal journeys.
