This could be a general nature question, but I am putting it in general instead of in nature talk, because I am thinking specifically about observing to take records for this website.
How much physical effort and strain is observing for inaturalist?
To me, it is a difficult thing, when I am going out to get many diverse observations and to really survey an area. Obviously, if I am taking pictures of birds in a city park, less so. But when I go out to get observations of mammals, birds, plants, insects, fungi from an area? It is a lot of effort. I also ride my bicycle and spend a lot of time outside, but really observing is a lot more effort than that.
Some of the things that can make observing difficult to me are: kneeling, stooping, and in general contorting myself to take pictures from the right angle, moving over rocks or uneven ground, and lifting up and shifting rocks and logs. Staying still, and moving slowly, to take photos of birds is also pretty difficult. Sometimes I get eyestrain from trying to see birds or other animals in light and shadow.
So I would say that for me, observing is pretty physically difficult. What has been your experience?
