What is the collection of scientific data through observation in the field such as observing the behavior of birds?

The collection of scientific data through observation in the field is known as field research or field studies. This approach involves systematically observing and recording behaviors, interactions, and environmental conditions in the natural habitat of the subjects, such as birds. Field research allows scientists to gather real-world data that can provide insights into ecological patterns, species behavior, and conservation needs. It is essential for developing a deeper understanding of biological and ecological dynamics in their natural context.
