Excellent tips, Josiah!
I would like to add that if you have been covering the same area for
multiple years, it is best practice to use the same protocol as used in the
past so that trends will not be influenced by changes in the way birds are
counted or estimated. After all it's the year-to-year trends that are most
important in long-term projects such as Christmas counts.
My opinion, FWIW.
