Wisconsin's Hummingbird Migration Timeline: Predicting Their Return Based on Past Patterns

Late Spring Arrival (Mid-May): Ruby-throated Hummingbirds usually arrive in Wisconsin around mid-May.

Nest Building (Late May to Early June): Males typically arrive first, followed by females who start building nests.

Feeding Frenzy (June to August): During the summer months, hummingbirds feed on the nectar of flowers, as well as insects for protein.

Fall Preparation (September): By late summer, hummingbirds begin preparing for their return south.

Departure (Mid-September to Early October): Migration begins in late September, and by early October, most hummingbirds have left Wisconsin.

Weather Influence: Hummingbird migration can be affected by weather. Cold fronts or warm winds may prompt earlier departures or later arrivals.

Daylight Hours: As days shorten, their internal clocks trigger the urge to migrate. The length of daylight is one of the cues they use to determine when to start their migration.

Feeder Use: Hummingbirds often stop at feeders during migration, so putting up a feeder in spring and fall can help attract them during their journey.
