What makes nests in trees

Like other yellowjackets, baldfaced hornets build papery nests. While yellowjacket nests are mostly in the ground or in voids in buildings, baldfaced hornet nests hang mostly in trees or shrubs, but can also be found under eaves, in attics, or attached to a building. Nests in trees are usually hidden in vegetation and not noticed until late fall after leaves are gone. A single, overwintering queen began building that nest in the spring.

She laid eggs and tended the first batch of larvae that developed into workers. Those workers tend new larvae and expand the nest throughout the summer. They chew the fibers and mix them with saliva to make a pulp which is painstakingly put into place mouthful by mouthful to form the envelope. Nests are pear-shaped and can grow to be up to 14 inches in diameter and 23 inches long, with the larger end at the top and an entrance hole near the bottom.

Osprey prefer trees with a broken top, which give them a clear view of the area around the nest. Red-tailed hawk nests are smaller than eagle or osprey nests, and can be as deep as or deeper than they are wide.

They have a fairly tight construction, and the sticks that compose the nest tend to be smaller than those used for eagle or osprey nests sticks generally inches in diameter. Nests tend to be in the crown of tall trees that give the hawk good visibility. Red-tailed hawks may also nest on transmission line towers and billboards. Red-tailed hawks may being nesting in late February, although in the upper Midwest they may not lay eggs until mid-April.

Red-tailed hawks build much smaller nests than eagles with smaller sticks. The photo on the right shows the relative size of the hawk nest; this nest is not large enough to support eagle chicks once they are larger.

Crows can be found year round throughout the Midwest. Ravens, although not as common as crows, can be found nesting in northern Minnesota, Wisconsin, and Michigan. Ravens tend to nest on cliffs. They are similar in size to squirrel nests drays. Crow nests usually measure less than 2 feet in diameter, and can be up to a foot deep. They tend to have a fairly tight construction.

Crows will begin nesting as early as March and as late as June. Photos courtesy of Kaeli Swift, Corvid Research. A small crow nest in spring showing fairly loose construction left ; a larger crow nest with a tight construction and incorporating human-made materials right.

They may use nests made by Red-tailed Hawks, crows, herons, squirrels, or even eagles. Owls begin nesting in late February - April.

Owls will typically nest in tree cavities or will use nests of other birds. It is difficult to tell if a nest belongs to an owl without direct observation.

This nest is too small and flimsy to support eagles. Heron nests are almost always near water. Heron nests are composed of sticks, flat and broad, and resembling a thin platform. Herons begin nesting March or April. Heron nests are almost always found in groups; they are flat and flimsy. These nests are too small and shallow to support bald eagle chicks. Squirrel nests or drays can reach basketball size or larger. Squirrel nests lack the structure of a raptor nest; there is no bowl for chicks and would not support much weight.
