Spring bird migration appears to be peaking, with a major movement of warblers and other songbirds taking advantage of the ideal wind flow north.

The Cornell Lab of Ornithology’s Bird Cast Migration Dashboard for Wisconsin, https://dashboard.birdcast.org/region/US-WI, at peak migration traffic showed almost 50 million birds in flight overnight into Friday morning.

The week already had a wave of warblers pass through at Six Mile Lake on Monday, with five species photographed within a half hour, at least one more — a male redstart — seen and a yellow warbler and a common yellowthroat heard singing. All are considered common — most, not surprisingly, were male and female yellow-rumped warblers, thought to be the most numerous warbler species in North America — but they still add some nice color when they can be spotted in the fast-developing spring foliage.

Other neotropical migrants — birds that winter in Central and even South America — such as orioles, rose-breasted grosbeaks and ruby-throated hummingbirds all have returned within the past week as well. So take the time to watch and listen, because it’s the best and easiest season of the year to see these birds.
