  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
