I went on my first Evanston North Shore CBC in 1962 when I was 13 years old, and I continued for 13 years until I moved.  I am now in Philadelphia at the Academy of Natural Sciences of Drexel University and remain a birder but as a scientist I focus on fish so my tabulations of (tribulations with?) both groups continue. Some may even say I count obsessively. Population assessments are vital in understanding species and how best to manage them. Illustrated through personal anecdotes, this talk will explore different methodologies, illustrate how population numbers obtained for one purpose can be used or misused for other purposes, and will look at specific examples of population assessments.
