Also agree. I have taken a few images of birds in nests, always with conservation principles in mind. This owlet was actually from a relatively close distance (17 m according to the EXIF) – the nest was at
Mt. Auburn Cemetery, America's first landscaped garden cemetery and a well-known spot for birdwatchers (especially during the spring warbler migration). In this case, the Audubon Society had taped off an area around the nesting site to keep people away, important because although it's a quiet area there is ample foot and vehicle traffic through the cemetery grounds.

Although no longer listed as endangered in Massachusetts, there are estimated to be only <80 pairs of bald eagles in the state. A few years ago, a fellow birdwatcher and Audubon Society member took me to the location of a nesting site. In this case, we were quite distant – 150 m according to the EXIF, and on the opposite side of the Merrimack River.
