Friday the 13th, an unlucky day for some people, happened to be a lucky day indeed for my friend and fellow birder Warren Roske. Warren saw a northern goshawk on Friday at Evergreen Lake. This is one of the few sightings of a goshawk at the lake. But it was no accident that Warren was birding there, as he, my friend Loie Evans and a few other birding friends try to keep a daily tally of the birds at Evergreen Lake. They post which birds, and how many individuals, they see on a bulletin board on the Lake House side of the boardwalk.
