All:
I just called *Denver office of Parks and Wildlife.* They told
me that if 3 or more birds were seen dead, within 24 hours, to report them
in to the Division in your area. See phone number lists in this link:
They also mentioned that you could bring dead birds in - but get full
instructions from the local office before doing this - and use extreme
care! (gloves, masks, garbage bags, ect.)
Yeesh, this is sad. I was hoping we wouldn't be seeing die-offs like we
saw last year.
