How many bird species were recorded during the 19th Sunday Bird Walk at the National Zoological Park?

  1. A.26
  2. B.36
  3. C.46
  4. D.56

Correct answer

C. 46

Explanation

The correct answer is 46. During the nineteenth edition of the walk, held from half past seven in the morning until half past ten, the eighteen participants recorded forty-six species of birds and observed more than five hundred individual birds in the area set aside for the activity. The walk was guided by an ornithologist with the support of volunteers, and the observations fed into field-level documentation of biodiversity, giving the participants a practical experience of citizen science. Options A, B and D are wrong because they do not match the count reported for this edition. The expert also spoke about the ecology and behaviour of birds, their part in keeping the ecological balance through natural pest control and their worth as indicators of the health of an ecosystem, which is the conservation lesson behind the figures.
