With bird flu in Delaware, is it safe to fill bird feeders? What to know
First severe case of bird flu reported
Just days after the CDC reassured people that the risk of contracting bird flu remains low among humans, the agency reported the first case of severe illness caused by an infection in the United States.

Despite the detection of avian influenza in Sussex County snow geese and Kent County broiler chickens, the Delaware Department of Agriculture says you can continue filling your bird feeders – unless you also keep chickens or live near some.
Anyone who owns poultry, including backyard flocks, should remove their birdhouses, feeders and baths, Delaware Department of Agriculture spokesperson Stacey Hofmann said. People who live near poultry should do the same to reduce the risk of the virus spreading from wild to domesticated birds.
The general public, however, can continue using bird feeders, Hofmann said. Delaware bird feeders typically attract cardinals, chickadees, titmice and other songbirds, while bird flu is usually found in waterfowl, raptors and vultures.
The department’s advice comes after the highly pathogenic H5N1 avian influenza was found in sick and dead snow geese at Prime Hook National Wildlife Refuge last week, marking the first detection of H5N1 on Delmarva since May 2022. On Thursday, the department announced presumptive positive testing in a Kent County poultry flock.
How to prevent the spread
Regardless of the prevalence of bird flu, backyard birders can prevent the spread of all bird illnesses by following a few simple steps, according to various agencies.
- Clean bird feeders once a month with a solution of nine parts water to one part bleach. For wooden bird feeders, use regular soap or a solution of three parts water to one part vinegar.
- Change bird bath water every two or three days.
- Never touch wild birds and always wash your hands after handling bird feeders and baths.
If you find a dead bird, wear gloves, a mask and safety glasses to handle it, the Delaware Department of Agriculture recommends. Double-bag the bird and secure the bags with a zip tie before putting it in a trash can.
If you see a sick or dead bird, call the Delaware Department of Natural Resources and Environmental Control’s Wildlife Section at 302-739-9912 between 8 a.m. and 4:30 p.m. Monday through Friday. After hours, report sick and dead birds here.
What to know about bird flu
Avian influenza is a highly contagious airborne respiratory virus that spreads quickly among birds through nasal and eye secretions and manure, Hofmann said.
The virus also has been detected in U.S. mammals, including foxes, wild and domestic cats, bears, seals, dolphins and cattle, according to the U.S. Department of Agriculture – but not in Delaware specifically.
Bird flu has occasionally infected humans, but continuous testing of people in close contact with infected animals indicates humans are at a low risk of contracting it, Hofmann said.
Since April 2024, there have been a total of 61 reported human cases of H5 bird flu reported in the United States, according to the Centers for Disease Control and Prevention. In Delaware, one person has tested positive this year, with the source of exposure unknown.
