It is time for the 2010 Christmas Bird Counts! Below is everything I can think
of for the Delta count.
Compiler: Dennis Garrison [email protected]
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.
