The Portland CBC feeds into a data set that encompasses over 1,000 CBC count circles across North America and as far south as Brazil. This was the 120th year for the CBC, making it one of the longest running large-scale data sets in existence. Hundreds of studies have been published using CBC data, and findings have been used to inform climate change science as well as important management and conservation decisions that have helped protect birds across their flyways.
On Portland’s count, Lori Hennings documented a Townsend’s Solitaire in the Beaverton sector, winning this year’s coveted “eagle eye” award. Congratulations, Lori! Other notable birds this year included Ring-necked Pheasant, Black-crowned Night-heron, Rough-legged Hawk, Northern Pygmy Owl, Tree Swallow, American Dipper and Swamp Sparrow. High numbers of Lesser Scaup, Brown Creeper and Lesser Goldfinch were observed, and a record six Black Phoebes were recorded on the count! The five species sighted most included Cackling Goose, American Robin, American Crow, European Starling, and Lesser Scaup.
Heartfelt thanks to all the area leaders, field counters, and feeder watchers for making this year’s Portland CBC another outstanding success. We look forward to seeing you again next year. In the coming months, stay tuned for a report of 80-year wintering bird population trends using long-term data from the Portland CBC. Read more about this on-going effort in the December 2019 Warbler (pages 13-14).
