There is a nest nearby. I can’t see it, but I know it is tucked high in the tall Douglas-fir overlooking the river.

Most Bald Eagle nests are within one-half mile of a body of water. After all fish is one of their favorite foods. The water, in this case, is a coastal shoreline and the Coquille River. Bald Eagles will also nest near bays, lakes, farm ponds, especially if they can find large trees, an unobstructed view of the water, and few humans.

Their shadows smoothly slide across the grass. Today they hunt.

Bald Eagles will hunt over large areas soaring up to 10,000 feet. In addition to fish, they will also take other animals such as birds, turtles, and mammals (like rabbits and rodents). They are not particularly fond of mammals, but will take them or mammal carrions.

Carrion, particularly in the winter, is frequently scavenged. They are considered to be an opportunistic predator meaning that they hunt when necessary and scavenge carrion when possible.

Every once in a while, they fly back to the nest clutching a large and noticeably heavy fish. Makes a weird shadow. Scares the little birds.

These large raptors are scary. They can sport a wingspan of up to 8 feet! Their body is just a few inches short of a yard. Adult birds can weigh upwards of 14 lbs. As with many birds, the females are larger than the males.

Bald Eagles will hunt other birds (such as geese and gulls). They are known to harass other eagles and Ospreys in an attempt to steal food from them. They are also known to occasionally steal food from other mammals and occasionally humans.

Big birds need big nests.

Bald Eagles build some of the largest nests of any bird. The size will depend on the supporting tree but are often 5-6 feet in diameter and 2-4 feet tall. The nest can weigh upwards of a ton! The largest recorded Bald Eagle nest was found in St. Petersburg, Florida. It measured nearly 9 ½ feet in diameter and just over 20 feet tall.

Building a nest is serious business and can take up to three months to build. These nests may be used over many years with additional materials being added each year. Sometimes ground nests, on cliff sides may be built.

One glance and you know what the little birds see.

Feathers of the adult Bald Eagle are quite distinctive with the white head and tail, brown body, with yellow beak, eyes, and feet. The distinctive color appears when the bird reaches four to five years of age. Both sexes have similar plumages.

Bald Eagles live a long time.

The oldest recorded wild bird, killed by a car in 2015, was at least 38 years old. Birds in captivity are known to live even longer.

Attack of the Giant Green Anemone!

Anemones living in caves are not as bright green as those living in sunnier areas.

This could be a somewhat believable title for a cheesy horror movie. After all, Giant Green Anemones are carnivorous. Not to worry! The sting is harmless to humans.

These beautiful flower-shaped creatures feed on small fish, newly molted crabs, sea urchins, detached mussels, and bits of marine plants. Some fish have developed protection against the anemone’s sting by covering themselves with mucus.

Little Giants

Even though Giant Green Anemones carry the name ‘Giant’ most only measure between seven and 12-inches.

They live a solitary life, and sometimes congregate in small groups (less than 14). These small groups create what looks to be a beautiful underwater floral arrangement. They will change color depending on the amount of light they receive. Different types of anemones will have other colors.

A Deadly Crown

Giant Green Anemones sport an oval crown of six or more rows of tentacles. These tentacles have stinging cells that help protect the anemone from predators. The tentacles also stun prey and help pull the prey into the anemone’s mouth.

Predators include seastars, snails, sea spiders, and fish. Some predators feed on the tentacles and others feed on the column.

Finding Them

Giant Green Anemones stay in the same location most of their lives. They can slowly walk around and swim to escape predators or when detached. These little giants are found in intertidal zones from Alaska south potentially as far as Panama.

Intertidal zones are areas that are above the water level during low tide. Anemones prefer areas where water is present most of the day such as tidepools and relatively shallow harbors.

Low tide will sometimes expose Anemones clinging to pilings and rocks, or even on the beach. When exposed, the anemone will ‘droop’ or close up into its green and brown stem while waiting for the incoming tide.

The fragile, yet harsh Intertidal zones are a challenging place to live but does provide some predation protection. Water conditions can be challenging. While the tide is regular, the shore may not pool the water. The water may be salty one day and diluted by fresh rain the next, and hard wave action can carry one out to sea. Still, many species, like the Giant Green Anemone, thrive there.

Amazing Factoid: A compound from the Giant Green Anemone is used by the pharmaceutical industry to create a beneficial heart stimulant for humans.
