We chose to visit Michigan in early June to see one of the rarest birds in North America, the Kirtland's Warbler. The Kirtland's Warbler breeds only in Northern Michigan and Wisconsin, and relies on a very specific habitat of young Jack Pines, 5' - 20' tall. Loss of this habitat and increasing parasitism by Brown-headed Cowbirds landed the Kirtland's Warbler on the Endangered Species List in 1973, with its numbers having fallen to around 400 birds.
Preservation of the Jack Pine habitat, including regular controlled burns to maintain trees in the preferred height range, along with aggressive trapping of Brown-headed Cowbirds has led to a spectacular recovery of the species, with the current population estimated to be around 4000 birds.
Early June is the best time to see these birds, as the males are singing to attract females and establish breeding territories. We signed up for a Michigan Audubon sponsored trip, which run daily from late May to the end of June. We met our group and leader at 7:00 at Hartwick Pines State Park, and after a short introduction caravanned in our own vehicles to a site about 30 minutes away.
The best locations for Kirtland's Warbler changes based on the age of the Jack Pines, but our trip leader Baxter knew exactly where to take us, and we were hearing and seeing warblers within a minute of getting our of our vehicles.
It's getting pretty tough for Teri and I to find life birds (birds that we've never seen before) in North America, but this one was easy! The group walked up a gravel road for about a mile, and then returned to the cars. Along that stretch we saw and heard around a dozen Kirtland's Warbler males singing.
We headed back to Hartwick Pines State Park after the walk, and birded around the visitor center and on the trails for an hour or so.
We saw another nice Rose-breasted Grosbeak male, and I couldn't resist taking more pictures!
Congratulations on a new life bird. Cool that you didn’t have to go to great lengths to see this one with your own eyes.
ReplyDeleteGlad it was easy - after going all the way to Michigan of course!
ReplyDeleteIt was nice to get a good look without having to search all over the place.
