I had not been getting SCBIRDCL attachments, but I received Deb's PIGR
photo, so some change apparently happened.
To respond to Deb's post, I attach a Pine Grosbeak graph that I created
from PA Christmas Bird Count data. Pine Grosbeak used to be a bird seen
annually in the state CBC, but now is rare in the state, I suspect because
winters have become warmer. It is almost hard to believe that >25% of PA
CBC sites reported Pine Grosbeak, as happened six times during the
1950s-1970s.
To summarize winter finch data, I like to use two variables: the percent of
sites reporting to assess incidence and the mean count/10 party-hours to
assess density. That is why there are two trend graphs in this figure.
I have encountered Pine Grosbeak two times in central PA, both at Black
Moshannon SP, in 2001 and 2002, but I don't think that it will happen again.
