I actually thought for the longest time that it was birds making that noise, @joanstewart! It wasn't until a few years ago, when I was taking a picture of one and noticed the sound was coming from him... 😂
And I completely agree - I was SO tempted to pick and pan fry those beauties, but my fungi ID skills aren't strong enough for me to feel confident enough to do so.
Hope you're having an amazing weekend!
