As pointed out by several people, the posting that you received from Lynn
Purcell's email address is spam. I mentioned a similar one from another
email address recently, and both of them used "hello" as the subject. The
Audubon server usually is good about filtering these out before they are
distributed to us subscribers, but some manage to get through. In the case
of each of these two emails, the "sender" is a subscriber whose address book
likely has been hacked, so these subscribers are not to blame. In all
instances such as these, as well as any other listserve-sourced postings
that only contain a link and no mention of birds, I would recommend deleting
them. Clicking on the link in the email might take you and your computer to
places where you don't want to be (including being the next person whose
address book is hacked). Better paranoid than sorry. I will contact the
person who oversees all of the Audubon listserves and mention this to her.
Oddly, neither of these two postings appeared on the Nevada page of
birdingonthe.net, the listserve compilation website.
