Subject: [NHBirds] November County Challenge: Final Results
Greetings all,

The dust has settled, I finally took a look at the eBird review queue, and
am hereby presenting the final standings for the 2025 NCC (sorry about
the extra columns).

County MAX 2025 end end % rank








Belknap 138 87 63.0 3








Carroll 152 73 48.0 10








Cheshire 165 96 58.2 8








Coos 139 94 67.6 2








Grafton 166 101 60.8 6








Hillsborough 169 106 62.7 4








Merrimack 191 104 54.5 9








Rockingham 273 171 62.6 5








Strafford 188 112 59.6 7








Sullivan 137 95 69.3 1









Perennial contender Sullivan started off strong, dropped to third at the
first turn, but came back in fine form to win the contest for the third
year (we've done this six times). Both Belknap and Coos started slow but
ended up medalling, Coos for only the second time. The middle of the pack
consistently consisted of Grafton, Hillsborough, and Rockingham, with
Hillsborough barely eeking out an edge over Rockingham at the wire (62.7%
vs. 62.6%!). Merrimack choked, as usual, after a good start (#2 to #9), and
was joined this year in this regard by Cheshire (#3 to #8). Poor Carroll, a
champion as recently as 2023, trailed throughout. The final standings for
all six years are presented below.

County 2020 2021 2022 2023 2024 2025 Ave Rank
Belknap 9 3 2 1 2 3 3.33 1
Carroll 3 4 1 2 10 10 5.00 4
Cheshire 2 8 6 9 8 8 6.83 9
Coos 7 6 7 3 7 2 5.33 5
Grafton 10 5 5 5 4 6 5.83 6
Hillsborough 4 2 3 8 5 4 4.33 3
Merrimack 5 10 9 10 9 9 8.67 10
Rockingham 8 7 4 7 6 5 6.17 7
Strafford 6 9 10 6 1 7 6.50 8
Sullivan 1 1 8 4 3 1 3.00 1

Several folks have asked this year about scoring, so I'll summarize
briefly. A county is ranked by the percentage of its ALL TIME species list
(in eBird) that is seen in the month. for example, Cheshire County has 165
species listed for November and birders reported 96 species in November
2025 - or 58.2%. I did this to give counties with fewer species and/or
birders a fighting chance, since we all know that if total species was the
metric Rockingham would win hands down every year without even trying. It
turns out that this handicapping system flips the bias completely
towards counties with lower overall species lists (typically those that are
small, farther north, and/or with fewer birders). If one of the more
populated and diverse southern counties does well it's usually because
someone (e.g., Robyn in Strafford in 2024) goes absolutely bonkers trying
to find new species, and even then a similar effort in a county like
Belknap can still result in a strong showing. As Steve said, it's probably
simply not possible for Rockingham to win this thing using the current
system..

Over the years, I've experimented with different ways to score this game,
including but not limited to:
1) only looking at the species lists over the last 5-10 years (this would
theoretically weed out some of the list-building rarities in
heavily-birded counties like Rockingham and Merrimack)
2) not counting species found fewer than 5 times in a county (same
rationale as above)
3) using as the denominator a number based only on the duration of the NCC.
I tried this in 2024 using the average, max, and cumulative November counts
for each county from 2020-2023.

In the end, NONE of these worked any better, and all of them took a lot of
time on my part to update. This year I saved myself a lot of time by not
updating as frequently, not checking the eBird review queue until the end,
and not trying any new scoring systems. I also spent most of the month
moving and settling into a new house, and dealing with the minutiae of the
NCC was not high on my priority list.

As others have noted, the NCC is a great way to get people out birding
during the "shoulder season" between fall migration and the Christmas Bird
Counts. It's been great to see folks showing their county pride (or
bemoaning their dismal showing), but I'm wearing thin on coordinating it
unless a couple of things happen:

1) Someone figures out a different way to score the contest
2) Other people step up to help - perhaps something like a county
point-person who can wrangle the data. The latter would ideally include
eBird review, although that's not the way this happens in NH at present so
might be hard to implement.

Any statisticians or county team leaders out there willing to lend a hand?

Good birding to all,
Pam Hunt
