I have not seen any this year at our feeder, and I not recall not
seeing any last year either.

At first glance at my data, it seemed that Pine Siskins are always
common in fall. However, a year-by-year breakdown shows a rather
Some years are good and some years are bad.
By the end of November in 2004, I'd had 8 weeks of solid Pine Siskin
sightings. But in 1997, as with this year, I've had none.
Here's a quick look at the monthly sightings by year from my data
(showing the number of weeks in that month that I recorded PISI):
Oct Nov Dec
1995 3 2 2
1996 1 1 0
1997 0 0 2
1998 2 4 3
1999 0 2 5
2000 2 3 4
2001 4 3 4
2002 2 4 4
2003 1 3 5
2004 4 4 5
2005 0 0 -
This data includes my weekly Marymoor visits (so I'm certain to have had
at least 1 trip per week per year), plus observations at my feeders,
plus any other birding trips I went on. Simply looking at whether I
found siskins anywhere, anytime during each week should help mask
differences in "observer effort" - that is, even if I had multiple
siskin sightings within a particular week, it only gets 1 "point" above.
So, this looks like a bad year. Are they dead, or elsewhere?
