3. Presenting the Module • Technical explanations Indoor exercises

4. How to count waterbirds • Knowing how to count waterbirds is: • Knowing when to count and when to estimate • Knowing how to count a small group of birds • Knowing how to estimate a large group

5. Count or estimate? • Objectives of the Module • At the end of this Module you will be able to: • List the deciding factors between counting or estimating  • Make a quick decision whether to count or estimate when faced with a given situation

6. Count or estimate? • Indoor exercise • Procedure: working alone or in groups • One trainee examines the scenario, describes what they see and chooses whether to count or estimate, and explains the decision • The decision is discussed with the other trainees

19. Count or estimate? • Indoor exercise • Summary of parameters and choice of method • Procedure: group work • Make a summary of the scenarios encountered • Present this summary as a table of “When to estimate? When to count?”

20. Count or estimate? • The main questions to be asked when deciding whether to count or estimate are: • What time is available for this census? • What is the approximate group size? • Is the group dense? • Are the birds moving around? • Could a possible or real disturbance disrupt the count? • Is the count site extensive? • Is visibility good?

21. How to count waterbirds? • Knowing how to count waterbirds is: • Knowing when to count and when to estimate • Knowing how to count a small group of birds • Knowing how to estimate a large group
