2015 Christmas Bird Count Report

History of the Christmas Bird Count
  
Prior to the turn of the 20th century, hunters engaged in a holiday tradition known as the Christmas "Side Hunt." They would choose sides and go afield with their guns—whoever brought in the biggest pile of feathered (and furred) quarry won.
Conservation was in its beginning stages in that era, and many observers and scientists were becoming concerned about declining bird populations. Beginning on Christmas Day 1900, ornithologist Frank M. Chapman, an early officer in the then-nascent Audubon Society, proposed a new holiday tradition—a "Christmas Bird Census" that would count birds during the holidays rather than hunt them. So began the Christmas Bird Count.
Count Day
2nd January 2016
It was the perfect winter day: sunny, crisp and calm. Forty three Bowen Islanders set out at the crack of dawn or settled in front of their feeders for a day’s birding with the intention of counting each bird seen throughout the day. This activity forms part of the annual Audubon Christmas Bird Count (CBC), now in its 116th year, and conducted all over North America by citizen scientists like our own Bowen Islanders. The data collected over the past century allow Audubon researchers, conservation biologists, wildlife agencies and other interested individuals to study the long-term health and status of bird populations across North America.
Collectively, we spent 93 hours in the field and tramped an impressive 98 km, recording a total of 3595 individual birds from 61 different species. A fantastic total that just goes to show what a rich and ecologically significant place this island and surrounding waters is that we call home. The most abundant bird was the Surf Scoter. The Surf Scoter is a sea duck that breeds on the lakes and ponds of the Arctic during the summer, but spends most of its time on the sea. The Pacific Northwest is a particularly important area for the Scoter, where it feeds on the clams and mussels of our coastline before following the herring spawn back north in the spring.

Results
Many great birds were recorded, no rarities but an excellent diversity of species nonetheless. Very good sea bird numbers were seen around the southwest side of the island, including four Grebe species (Horned, Western, Red-necked and Eared) and many Marbled Murrelets.
A healthy flock of Red Crossbills were recorded at Cape Roger Curtis and four Surfbirds were observed in the Tunstall Bay/Sealy Park area.
There were a fantastic number of Bald Eagles recorded with 52 adults and 53 immatures in all. It is highly likely many of these were duplicate sightings; however I witnessed a constant stream coming in from the North West throughout the day.
One surprise for me was the number of Pileated Woodpeckers, 23 in total – who knew there were so many on Bowen!
The densest area for birds was the southwest, due predominantly to the good numbers of sea birds. The species count was more evenly spread across the island with all areas having good numbers, the exception being Grafton Lake which yielded only 6 species, although one was a beautiful “Sooty” Fox Sparrow.
I’d like to thank everyone who participated in what was a wonderful day!
