If you see mostly sky, this is characteristic of a clearcut or non-forested habitat such as a meadow with scattered trees present. If you see mostly treetops and very little sky, this is considered closed canopy forest. Large acreage of closed canopy forest is essential habitat for forest interior-dwelling birds, such as the scarlet tanager, the ovenbird, and the American redstart as well as many other species of warblers and vireos. Exposed perches add to the structure of habitat. High perches, in the supracanopy level, are dead or live perches on trees above the surrounding forest canopy.
Pasture trees are high perches above the herbaceous level.
These high perches are frequently used as hunting perches. The belted kingfisher is an example of a species that uses several habitat levels. For its nest site, it makes a burrow three to six feet deep in a bank of sandy clay or gravel, within a mile of water. Their preferred feeding habitat is the shallow borders of bodies of water. Here they must have perches at shrub level or midstory to sight prey in clear water and to use as feeding sites.
