Re: [cobirds] Dead and Dying Geese in Thorton CO

My experience with turning birds into DPW is that, once they have documented instances of avian flu in an area, they don't really need more birds to test. That was according to the DPW office in Littleton.
 I think they still want to know if there is any kind of mass die off. So sad, I never wanna see one dying of it again, it's brutal.

During the last dieoff, a TV station reached out to Aiken Audubon to interview us on the subject. We then called another TV station for another interview to make sure folks knew what, and what not, to do if they found a dead bird.

A LTE to your local paper is another option.

I'll reach out to Michael Booth at the CO Sun.

Contact the CPW for your area if you find three or more dead wild birds in a specific area within a two week period OR if you see live birds showing clinical signs.

CPW will advise what to do once they're contacted. While the spread is not common to humans, precautions must be taken to prevent that. There is risk to domestic birds, cats, dogs to consider as well. 

Unless specifically directed by CPW, no specimens should be brought to them. They have a responsibility to interview any person that does contact Birds that have died from avian flu to assess the risk of spread.

I am not sure about DMNS, but we are dealing with a highly pathogenic strain of avian flu, so human handling of carcasses should be extremely limited and only carried on through professional instruction. 

In past years, CPW has provided a resource for Bird Conservancy Bald Eagle Watch volunteers to collect information from observers. I will check if that is still ongoing for this season and update the group.

All,

Am I mistaken or can we collect birds and take them to CPW for testing? Or DMNS?

Of course you'd need gloves and a large bag.

I'm not aware of this occurring in El Paso County.

I had the same experience at Jumbo last week. Several dead and dying white geese there as well.

John et al,

Lots of dead "white" (Snow/Ross's) geese apparent at John Martin Res/Lake Hasty two weeks ago.  This area is historically hunted heavily but my sense was the number of birds lying/floating around was more than would be a typical incidence of hunter cripples.  A few Canada/Cackling Geese are showing up at Sheldon Lake in Fort Collins City Park.

Subject: [cobirds] Dead and Dying Geese in Thorton CO

 

All:

         Several dead Canada and Cackling geese found at Hunter's Glen Reservoir and Eastlake in Thornton yesterday (12/7/25).  I'm guessing these are cases of Avian Influenza coming back to haunt us.  I haven't seen any recent state reports of the what the status of avian influenza are in the state, but there were articles about 8 months ago that it was still a danger (to birds) in Colorado.  

 

Is anyone else seeing die offs in other locations?
