New Brunswick’s Christmas Bird Counts

New Brunswickers have been participating in the Christmas Bird Count (CBC) since Christmas Day 1900 when William H Moore from Scotch Lake, part of today’s Mactaquac count area, became Canada’s first CBCer.

Fewer than a dozen CBCs took place in New Brunswick over the next 50 years, but in 1956, Austin Squires, curator of the New Brunswick Museum, encouraged New Brunswick naturalists to join other North American naturalists in doing Christmas Bird Counts. Dr. Squires laid out the format for doing a count and within a decade there were counts operating from Île Lamèque to Grand Manan. Perhaps 80 areas have been surveyed over time, but about 50 are regularly surveyed now.

In the mid-60s, David Christie, volunteering through Nature NB, took on the informal role of compiler for New Brunswick CBCs and for the next 50 years produced a provincial CBC summary which was published by Nature NB.

While today most CBC compilers post their data to the international database operated by Audubon, Nature NB has been by far the largest publisher of New Brunswick based CBCs. With only 30% of new Brunswick’s 2200 CBCs being available through the Audubon database, Nature NB has undertaken to provide access to every known New Brunswick CBC through its website.

Take part in a Christmas Bird Count

50 Christmas Bird Counts were undertaken in New Brunswick during the 2021 CBC season and, for the first time, all 50 posted their data to the international database supported by Birds Canada and managed by Audubon. Nature NB’s annual provincial compilation and summary is under preparation and is expected to be available shortly before the 2022 CBC.

Accessing New Brunwick’s Christmas Bird Count Data with Nature NB’s Finding Tool

Finding the results from any of New Brunswick’s 2200 CBCs is a two or three step process depending on whether you are looking for results from a particular count area or year or trying to find all the CBCs that have taken place in a certain area.

Some parts of New Brunswick have been surveyed only a few times — or even just once. Several areas have 40 to 50 years of continuous data. Cape Tormentine, including the 2020 CBC, has 60 years of continuous data that has all been published as well as posted to the free public database at Audubon.

Step One

Use the five CBC dataset profiles above (Bird Lore, Canadian Field Naturalist, etc.) to determine which dataset you wish to examine.

Step Two

Download the Excel-based Finding Tool and go to the appropriate dataset tab at the lower edge of the Finding Tool.

Step Three

Find the count area or year you are interested in and at the top of the column you will see the volume and number or date of the publication where that/those counts can be found. Note that the Audubon database has no issue numbers or dates; the database can be used to explore about 30% of New Brunswick’s CBCs by species, count area or time period independently of the Finding Tool.

Step Four

Leave the Finding Tool and, back to the Published Records section, click on the link to the appropriate dataset and proceed to the appropriate issue of the publication.

Data Commitment: Nature NB is committed to publishing the data from any as yet unpublished CBCs, whether previously unknown or up to now “lost”.

Data Caveat: Like all large datasets, there are likely errors in the data presented here. If you find things that are questionable please let us know. (Even in the data from New Brunswick’s first CBC there is a bust — Wm H Moore reported 36 individuals from 9 species, yet the results add to 34 individuals and 8 species!)

Data in Electronic Format: Digital versions of some count areas over their history, as well as some annual provincial compilations, are available in electronic format on request.
