75th Pickering CBC – December 30, 2023

We held our 75th Christmas Bird Count for Pickering on Saturday December
30, 2023.  The count was sponsored by Pickering Naturalists.  A total of 80
species were tallied, well above our ten-year average.  The highest count
of the past decade was 83 species on the 2020 CBC.  This year, there were
39 field observers and 9 watchers at 8 feeders, rather high but
substantially less than our record of 51 observers in 2018.  These
participants tallied 25,187 individual birds, somewhat fewer than last
year.  Our 20 teams were birding hard all day, and put in 101 hours of
highly focused bird watching effort (including 108 km of walking in 101
hours, and 723 km of driving in 46 hours).

Conditions on the day were mild.  The ground was mostly bare with
occasional snow-covered areas under dense cover.  Temperatures ranged from
-0.9 degrees C at daybreak to a high of -0.5 at noon, then fell slightly to
a low of -1.5 at dusk. Skies were cloudy all day.  Unsheltered areas
experienced moderately strong winds from the Northwest (to WNW or NNW),
from 5 to 9 at times but mostly from 15 to 18 km/hour, with gusts briefly
to 28.  Lakeshore areas had somewhat stronger winds.  Windchill was modest,
between -3 and -7.  Creeks and ponds were open.

From the beginning of the count in 1949, a total of 154 species had been
recorded, up to last year’s CBC.  A remarkable two species were added this
year – Barrow’s Goldeneye and Red-necked Grebe.  Barrow’s Goldeneye was
previously seen during count week only (in 2022) and R.N. Grebe had never
been seen at all.

This year, we had our highest-ever counts for Cackling Goose – 30 (previous
high was 8 in 2020), Red-bellied Woodpecker – 35 (previous high was 29 last
year), Common Raven – 23 (previous high was 22 in 2019), Hermit Thrush – 5
(previous high was 3 in 1989) and Eastern Bluebird – 17 (previous high was
13 in 2006 and 2010). Of these, both the woodpecker and the corvid have
been on steady upward trajectories for at least 15 years.  Counts that
matched our previous maximum were made for Merlin – 3 (seen in 2020) and
Winter Wren – 5 (seen in 1974).

Second-highest-ever counts were made for Gadwall – 100 (highest was 118 in
2018), Northern Shoveler (highest was 13 in 2001), Common Goldeneye – 463
(highest was 730 in 1966), Northern Flicker – 6 (highest was 13 in 1970),
Carolina Wren – 4 (highest was 6 in 2021) and White-throated Sparrow – 44
(highest was 54 in 1980).  Yet another statistic for us OCD CBCers,
third-highest-ever counts were made for Trumpeter Swan – 35 (highest was
110 last year), Red-breasted Nuthatch – 32 (highest was 69 in 2020), and
Northern Cardinal – 197 (highest was 264 in 2020).  We also had our
third-highest count for American Robin – 815 (highest was 1500 in 2016).
Over half of the robins for this year’s CBC (466) were seen at dusk,
apparently flying into the same roost site as on last year’s count.

Relatively high counts also included Pileated Woodpecker – 4 (highest since
1994) and House Sparrow – 501 (highest since 2006).  Other noteworthy
species included Eastern Screech-Owl – 2 (the first since 2002 – both
calling/responding to calls during the day) and Ruffed Grouse – 1 (the
first since 2013, yet another victim of our rapidly-urbanizing watershed).
A Gray Catbird was only our third-ever (previously seen in 1979 and 2020)
and a Fox Sparrow was our 4th-ever (previously seen in 2000, 2012 and 2020).

Species seen in low numbers included Greater Scaup – 73 and Herring Gull –
65, both well below average.  Our most notable misses were Glaucous Gull
(seen on 13 of the last 16 counts), Barred Owl (seen on 8 of the 11 last
counts), American Kestrel (seen on 20 of the last 23 counts) and Snow
Bunting (seen on 17 of the last 19 counts).

Two species were seen during count week, but were not found on the CBC day
itself – Canvasback and Glaucous Gull.

The Pickering CBC was initiated by Dr. J. Murray Speirs on Jan. 2, 1949.  The
count area extends from the shores of Lake Ontario north to the Oak Ridges
moraine.  It is centred at latitude 43.902 degrees north, and longitude
79.097 degrees west.  The CBC area incorporates the neighbouring community
of Ajax, as well as portions of Lynde Shores Conservation Area, including
part of Cranberry Marsh, in Durham Region.

information on the club.

A huge thank you to all of our field counters and feeder watchers.  We also
appreciate the major contributions of Dan Shire and Karen McKillop, who
assembled the final tallies and did data entry, and those of Carolyn King,
who recruited and maintained contact with observers, checked out long-term
averages and other species information, and stick-handled our CBC
spreadsheet across the blue line and into the slot.  Any miscalculations,
omissions or commissions of gross incompetence (and tardiness) may be
blamed entirely on the undersigned.
