It is time for the 2010 Christmas Bird Counts! Below is everything I can think of for the Delta count. Compiler: Dennis Garrison dennisgarri...@hotmail.com Date: 18 December 2010 (Saturday) Time: Meet at 8 am at City Market parking lot in Delta. Schedule: Bird until we get the circle done, freeze to death, or run out of daylight. Owlers contact me beforehand for some planning. Fee: $5 per adult, under 18 free. Please bring cash, I won't be able to make change. This $ goes to national Audubon for compilation of the CBC data and publishing of the report. Any additional donation $ collected goes to BCAS general fund unless specified by donor. Bring: warm clothes, snack and/or lunch, drinks, binoculars (I will have a pair to loan if needed), spotting scope, bird books. Provided: Map of CBC circle, slightly closer-up map of each group’s piece of the circle, checklist of birds which might be seen (and for you to keep count on), instructions. The plan: Meet at 8, sort ourselves out into groups that will fit in vehicles, divide up the circle appropriately, and go birding! Meet at the west parking lot of Confluence (the dead end around the back) at dusk to drop off data forms and see what might be on the lake. It would be helpful if participants could email Dennis and let him know they are planning to attend, for planning purposes. Data collected needs to get back to Dennis at the end of the day if possible, and if not, needs to be sent to him as soon as you can practically do it. Some statistics about the Delta count from the past ten years: The earliest count was on December 14, the latest on December 22. The fewest count participants was 7, the most was 19. The lowest # of species counted has been 71, the highest, 93. The coldest it has been has been -10, the warmest, 50. Snow has only been recorded once in the last ten years. Birds seen on only one count in the last ten years: Mute swan Common peafowl Wild turkey Common loon Eared grebe Great egret Northern goshawk Bonaparte’s gull Short-eared owl Steller’s jay Pinyon jay Pygmy nuthatch Hermit thrush Chipping, vesper, fox, and Lincoln’s sparrows Evening grosbeak (and one count week bird) Birds seen only in the count week in the last ten years: Tundra swan Varied thrush Gray catbird Black-headed grosbeak The ten most common birds (and average count for the past ten years) Canada goose 1934 European starling 1830 Red-winged blackbird 1186 Mallard 1052 Dark-eyed juncos 587 Song sparrow 318 Mountain bluebird 298 American robin 289 House sparrow 286 White-crowned sparrow 241 Last year’s results: 13 participants, 81 species, including two never-before-documented on the count, and roughly 7700 individual birds. Again, email me if you have any questions, or call (but I might not answer immediately).
