I am getting emails from birders seeking advice on whether they should take down their feeders in light of the latest outbreak of avian flu.

Here's what the Cornell Lab of Ornithology advises:

https://www.allaboutbirds.org/news/avian-influenza-outbreak-should-you-take-down-your-bird-feeders/

In a nutshell:

"There is currently very low risk of an outbreak among wild songbirds, and no official recommendation to take down feeders unless you also keep domestic poultry, according to the National Wildlife Disease Program. We do always recommend that you clean bird feeders and birdbaths regularly as a way to keep many kinds of diseases at bay. We will update this page as the situation develops."

(Thanks, Cornell!)
