With more cases of bird flu detected in wild and domestic birds across Michigan, the Department of Natural Resources suggests Michiganders take down their bird feeders and birdbaths out of an abundance of caution. 

Birds flock to Michigan in April and May as they migrate through the Great Lakes region after wintering in Central and South America. Migrating species, such as the colorful yellow-rumped warbler or the soaring broad-winged hawk, may seek out food sources in backyard bird feeders, causing some Michigan birders to worry about spreading the avian influenza, also known as the highly pathogenic avian influenza (HPAI), 

HPAI was first detected in the state in a backyard, nonpoultry flock of birds in Kalamazoo County in late February. Birds at the Detroit Zoo were moved indoors in response to protect from bird flu exposure. More recent cases of HPAI have cropped up across the state, including in household parrots in Washtenaw County on April 18

Megan Moriarty, DNR state wildlife veterinarian, said in a statement that bird species vary in how likely they are to die from HPAI infection. While all birds are potentially susceptible to bird flu, domestic birds — such as chickens, cockatoos or doves — are more vulnerable to fatal infection. 

In addition, some wild bird populations, like waterfowl, raptors and scavengers, are “highly susceptible and have been particularly affected by this disease,” Moriarty said in the statement. 

Songbirds appear less prone to bird flu, although Moriarty noted that testing of songbirds is limited and much is still unknown. 

“If you’re concerned about this virus and want to act from a place of abundant caution, removing your bird feeders for now makes sense, but it isn’t yet a critical step,” Moriarty said. “With warmer springtime weather on the way, too, birds will have more natural food sources readily available to them.”
