What does Count Week mean and how do I record Count Week birds? 

Key Facts:

  • Definition: Count Week = 3 days before + your official count day + 3 days after (7 days total).

  • Purpose: Documents species presence when NOT seen on count day—serves for local count record-keeping only.

  • Notation: Included in the CW section of the CBC data entry platform (no numbers, no dates recorded).

  • Does NOT count: Count Week birds don't add to your species total or count tallies. Only birds seen on your official count day contribute to count totals.

In Summary: Count Week records are not required. Count Day numbers always take priority. Only those species seen on Count Day are included in your count total.

Examples:
Example 1 - Species seen on Count Day:

  • You see 11 Great Blue Herons on Count Day → Enter 11 on your count checklist.

Example 2 Species NOT seen on Count Day:

  • You see Great Blue Heron 1 day before Count Day, but not on Count Day → Enter on CW on checklist.

Example 3 Higher numbers during Count Week:

  • You see 11 Great Blue Herons during Count Week, but only 4 on Count Day → Enter 4 on your count checklist.

Count Day observations are what matter, regardless of Count Week numbers.
