Hummingbird Nest Blocks Bridge Work

The problems are already starting with the new Trump infrastructure plan.

The massive 70$ million dollar infrastructure plan has run into a slight snag. It seems that a family of hummingbirds are nesting in a tree at the north end of the bridge and the construction team can’t start the work until the tree has been removed.

The little Nester’s are  protected under the Migratory Bird Treaty Act and the Metropolitan Transportation Commission cannot break the law by uprooting the little guys and moving the nest.

The nest — about half the size of a fist — was discovered about a week ago, when work was set to begin. The species, Anna’s Hummingbird, is protected and the law forbids the removal of the egg and offers other protections to birds.

Under the protection act, the tree cannot be taken down until the hummingbird baby is no longer in the nest. The act is to protect and manage migratory bird populations while they are in the nesting stage to make sure future populations will survive.

Hummingbird Nest Facts

Attracting hummingbirds is even more fun when
you find a hummingbird nest. Learn where to look.

Like a crown jewel, the nest of a hummingbird is one of the great wonders in all of nature. They are so tiny, yet so perfect. Few of us have ever seen a hummingbird nest. This is because they are nearly impossible to find. From the ground, they look like another bump on a branch. From above, an umbrella of leaves conceals them. And from the side, they look like a tiny knot, quilted with lichens, plant down and fibers. Though each of the 17 hummingbird species that breed in North America builds slightly different nests in various habitats, they have much in common.

Basic Hummingbird Nest Facts

Females build their nests 10 to 90 feet high, generally in trees or shrubs (with a few exceptions).

Hummingbirds build velvety, compact cups with spongy floors and elastic sides that stretch as the young grow. They weave together twigs, plant fibers, and bits of leaves, and use spider silk as threads to bind their nests together and anchor them to the foundation.

Hummingbird eggs are about the size of navy beans. Most females lay two eggs, which they incubate for 15 – 18 days.

Juvenile hummingbirds fledge (leave the nest) 18 to 28 days after hatching.

Attracting Hummingbirds to Nest

Any hummingbird lover knows that adding nectar plants to your garden is an important part of attracting hummingbirds. But these tiny creatures rely on a different set of plants for nesting materials. Add some of these to your garden to encourage hummingbirds to nest nearby.

Trees and Shrubs: Hummingbirds don’t use nest boxes or tree cavities. Instead they generally build their nests in sheltered trees or shrubbery, often in a fork of branches. Enhance your own hummingbird habitat by growing a diversity of leafy trees and large shrubs that provide shelter at varying heights. And if you want to get more bang for your buck, plant catkin-bearing trees and shrubs, which provide soft plant fibers for nesting material. Some examples of these include willows, witch hazel, alder, American elm, cottonwood, ironwood, poplar, birch, beech, mulberry and maple.

Hummingbird eggs are cradled in soft fluffy fibers that hummingbirds choose from plants nearby. Add plants with fuzzy foliage like Lamb’s Ear (Stachys byzantine), which forms dense, ground-hugging rosettes of thick, soft, woolly leaves. The silken plumes of ornamental grasses are also useful in attracting hummingbirds looking to nest. Some plants have seed heads or pods that transform into fuzzy balls of soft fiber, or are encased in soft protective casings. Examples include clematis, honeysuckle, milkweed (Asclepias species) and blanket flower (Gaillardia species). Pasque flowers offer both soft foliage with silken hairs, and mid-spring flowers followed by fuzzy seedpods.

Hummingbird Nest Characteristics by Species

While these are the basics for hummingbird nests, it is interesting to see what makes each of these species unique. Hal Harrison studied hummingbird nests for decades – here are some of his observations.

Anna’s hummingbird females build a mere platform as early as December to lay her eggs. Then she builds up the nest while incubating.

Black-Chinned hummingbird nests are deep cups, and the rim may be curved inward.

Blue-throated hummingbird nests are often built on electric wire inside or outside of cabins.

Broad-billed hummingbirds will build their loosely constructed nests on clotheslines.

Broad-tailed hummingbirds often returns to same nesting site year after year.

Calliope hummingbirds will build a series of two, three or even four nests on top of one another, often attached to a conifer cone.

Costa’s hummingbirds will colonize at favorable sites with as many as six nests in a 100-foot radius. The birds are very tame at nesting sites.

Magnificent hummingbirds build the largest and highest of North American hummingbird nests.

Ruby-throated females attach their nests with spider silk to a small twig or branch that slants downward and covers the outside with greenish-gray lichens. They may lay eggs in a second nest while still feeding the young in the first.

Rufous hummingbirds, a western species, are very pugnacious around the nest, often driving away much larger birds.

There ya go a little research into what is going on with our little hummingbird pals.
