Wild Bird Warning: UPDATED INFO From WILD BIRDS UNLIMITED
Tuesday, March 31st, 2009Keep an eye on your bird feeders and birds. There is an epidemic spreading among the finches and we have the poor little buggers dropping left and right out here. We’ve had to take in and sanitize all the feeders. We have also had to clean the areas where the birds congregate.
A sick bird will be lethargic and may not move away from you when you approach. Wild birds should disperse, but sick birds may even allow you to touch them or pick them up. Birds with conjunctivitis will be readily identifiable by the swelling around the eyes. If you can catch these birds and get them to a vet, they may be successfully treated. Otherwise, they will go blind and starve to death.
If you enjoy wild birds and have feeders, please take a moment to read this page at the university of Cornell.
If a sick bird comes to your feeder, minimize the risk of infecting other birds by cleaning your feeder area thoroughly. If you see several diseased birds, take down all your feeders for at least a week to give the birds a chance to disperse. Keep the feeders down until you no longer see diseased individuals. And remember that prevention is the key to avoiding the spread of disease. Regularly clean your feeders even when there are no signs of disease and prevent overcrowding by adding more feeders or setting up different types of feeders that allow only a few birds to visit at one time.
Please report any sick birds you see to the National Wildlife Health Center.
The National Wildlife Health Center has information about a recall of wild bird food tainted with salmonellosis, which has infected the birds here.
It appears the culprit may be, in part, tainted bird food, though salmonellosis occurs naturally in the bird population. And it can spread to people. Wash your hands, folks.
AN UPDATE FROM MARGARET COLLINS OF WILD BIRDS UNLIMITED:
While Wild Birds Unlimited Bird Food has been found to have been tainted with salmonella, there does not seem to be a direct link between the strain found in the dead birds and the bird food.
This was just released by the North Carolina Department of Agriculture and Consumer Services:
Test results of bird food from Wild Birds Unlimited, the retail source of the seed in question, indicated that Wild Birds Unlimited Wildlife Blend bird food with the specific manufacturing date code of 81132200 2916 08124 was positive for Salmonella. Also, Wild Birds Unlimited Woodpecker blend sold in 5-pound bags at a North Carolina store was positive for Salmonella. The bird seed Salmonella strain isolated during testing is different from the strain that is implicated in the current peanut product recall. These test results also indicated that the strain of Salmonella in the bird seed is different from the strain found in dead wild birds that have been examined by the NCDA&CS Veterinary Diagnostic Laboratory to
date.
And from the Center for Infectious Disease Research and Policy:
Nathan Ramsay of the US Geological Survey’s National Wildlife Health Center (NWHC) in Madison, Wis., said his center also has been seeing an increase in bird deaths related to Salmonella in the Southeast.
“It seems from probably around Maryland down through Appalachia we’ve been seeing an increase in Salmonella,” he said.
Like Keel, Ramsay said the reasons are unclear. “It seems like it’s a cyclical thing. Back in 1998 we had a large peak also, not only on the East Coast but also in the Midwest. It seems like every once in a while we get outbreaks that occur over a large area and in large numbers. We’re not exactly sure what causes that as yet.”
Ramsay, who is the lead necropsy technician at the NWHC, said the center has not run genetic tests on Salmonella isolates from birds this winter, but said “there doesn’t seem to be any connection” with the human outbreak.
He said he was not aware of an unusual level of Salmonella-related bird deaths in regions other than the Southeast, with the possible exception of Washington state.
Salmonellosis is a common cause of death in birds at bird feeders, according to the NWHC. The pathogen can spread from bird to bird through direct contact or through food or water contaminated with feces from an infected bird or mammal. Infected birds may appear healthy but can shed the organism in their feces.
To reduce the spread of Salmonella, the NWHC recommends cleaning feeders with a 10% solution of bleach in water, changing feeder locations regularly, and adding more feeders to reduce crowding.
I so enjoy having the birds at my window feeder every day. It has been a very sad sight to see these tiny, beautiful creatures grow sick and die, so I have taken down all feeders and sanitized everything. I look forward to being able to put the feeders up again, soon. We always keep multiple feeders on hand to clean and swap out, so we’ve always been conscientious about the health of the birds, but I have never seen anything like what we are seeing now. Even the birds in the woods appear to be ill and do not shy away when we approach.
Please pay attention to your bird feeders and the health of the birds in your area and report any signs of disease.
Thanks.
PS: Very relieved to know I didn’t poison the birds. We always shop at Wild Birds Unlimited, get great service, and I appreciate their contacting me to let me know what is up.
