Different groups of migrant birds in Michigan

I'm new to the area. Do a lot of birds winter in Michigan? ~ Lansing, MI 

That’s a very good question. In general, it's estimated that of the over 200 species of birds nesting in Michigan, about 90 percent migrate to some extent. Whether it’s from the U.P. to mid-Michigan or from our state to Mexico or Central America depends on the bird.
.
.In Michigan, birds can belong to several groups:
.
Male & Female Cardinal along with Black-capped Chickadee
Other bird species seen at the feeder year round may also be migratory. While we see American Goldfinch throughout the year, some of the ones we see in the winter may have nested in Canada. And Song Sparrows that breed in Michigan may migrate to the southeastern United States, or may remain a year-round resident.

They are obligate partial migrants, meaning only part of the population migrates annually. And sometimes circumstances such as a good breeding season followed by poor winter crops can lead to irruptions of bird species not normally seen in our area like the Pine Siskins or Redpoles.

It’s not easy getting every bird’s travel plans straight. For example one of my favorite birds, the Northern Cardinal, has expanded its range greatly since the days of John James Audubon. Originally a southern bird, the cardinal began expanding its range into northern states around the 1900’s. During the early days of the expansion, the birds would migrate back south during the winter, but in time they became a year round resident in Michigan.

Migration isn’t an exact journey. Using published literature, bird observer reports, and observations of bird watchers it has been found that many factors like the temperature changes and land development are very likely influencing birds’ migratory patterns and will continue to alter patterns in the future.
