Mist nets serve the purpose of capturing birds and insects for population monitoring. Although the tally of individuals caught in the nets can provide insights into the population figures of certain species, this method carries several drawbacks. On one hand, using counting points tends to yield more precise abundance estimates because the net captures are limited to a select few points over time. For studying canopy species, selecting days with minimal fog is ideal to fully view the species and the remarkable vegetation from high above; however, for capturing certain species for research, foggy days may be more appropriate.
