Sky Dancer

Sitting on a lonely fence post.
Staring down in silence.
Patient. Hunting.

Focus attack to prey.
Feet outstretched; talons sharp.
Killing. Surviving. 

Dangling legs and sharp talons.
The sky dance has begun.
Touching. Singing.

Climbing high to plunge.
Cartwheel dances in the air.
Thriving. Red-tailed hawk.

Red-tailed hawks are one of the most common raptors found across the U.S., northern Canada, and far south into Panama. Go for a ride and look for them hunting atop telephone poles, fence posts, trees—anywhere they can watch for prey and swoop silently.

Size

Adult female Red-tails are slightly larger than the males both in length (26 versus 24 inches), weight (just under four pounds versus under three), with a similar size difference in the over four-foot wingspans.

These are medium sized raptors are the largest in their genus (Buteu) with robust bodies; thick, broad wings; and relatively short, broad tails. The reddish, orange tail color is unique among North American hawks.  

Just for comparison, a similar-sized dog could
weigh 10 times what an average Red-tail might.

Color

Coloration will vary greatly but most adults have a dark brown upper head that almost looks like a hood. Feather coloration creates an imperfect “V” shape on its back. From below the bird is a light-buff orange.

Range and Habitat

Red-tail hawks are considered an American native based on fossil and current distribution studies. Some, but not all, of the birds will migrate, typically going north into Canada and Alaska for breeding.

This raptor is one of the most broadly distributed birds in the U.S. The large, year-around range for non-breeders covers the entire contiguous U.S. with no substantial gaps.

Red-tails have become habituated to almost any habitat in North and Central America. This could include tropical rainforests, to deserts and grasslands, to woodlands. Some are even found in urban areas.

In every case, they will be looking for high nesting and perching sites. Based on the area, ‘high’ may be a shrub or fence post, tall conifer, or telephone pole.

Hunting

A high perch gives the birds an advantage when hunting. Not only are they able to get a great view, but they are able to jump into an easy soar or quickly swoop down on prey almost silently. Minimizing wing flaps help to conserve energy which may be needed to get their prey back to the nest.

These carnivorous hawks are highly opportunistic feeders. It is not hard to imagine them taking small mammals, reptiles, fish, amphibians, birds, and invertebrates.

Let your imagination run a little wild. They will also take (or try at least) much larger prey carrying up to about five pounds in a load. Larger prey would be dismantled, temporarily hidden, while pieces are taken to the nest.

Remains of larger prey (such as armadillos, lambs, pigs, deer, sheep, and horses) have been found in nest sites. There are also stories of juveniles unsuccessfully trying to take adult wild turkeys and overwintering pairs hunting together.  Amazing!

Courtship

This bird has a great courtship process that can include daring ‘sky dances’ for and with their mates. These dances occur on the edge of the pair’s territory suggesting that it is also a way to designate territory limits.

Human Interaction

Red-tailed hawks are more social than other raptors and can be tamed and trained for hunting. The sport of Falconry was used in 2000 B.C. and is still practiced today. For more information see https://en.wikipedia.org/wiki/Falconry.

Note all parts of this bird are protected and regulated like eagles.

The long-term interaction with humans has created a rich record of data and images for this bird. More than a single blog could ever hold. Consider taking a little time to learn more about this amazing bird—you will be glad you did!

Tide pools offer an amazing opportunity to learn about ocean wildlife. One of the most recognizable animals is the Ochre Sea Star. Many people call Sea Stars a Starfish, even though these animals are not fish.

The Ochre Sea Star are related to sea urchins, sea cucumbers, brittle stars, and basket stars. There are approximately 1,500 known species in this animal grouping that inhabit artic, temperate, and tropical waters.

Habitat

Ochre Sea Stars prefer cold salt water and can be found in many Oregon all year round. They can be found on wave-washed rocky shores, tidepools, and amazingly out of water for limited times. Pisaster ochraceus can tolerate a loss of 30 percent of its body fluids for short periods, huge temperature changes, wave surges, and rain diluting salt water.  

Identification

These animals come in more than just ochre colors of yellow, orange, curry, and brown. This heavy echinoderm can also be reddish or purple in color. The radius of an adult Sea Star with five stout arms may be up to 18-inches in diameter. The size of the Sea Star is dependent on the food supply.

Prey

The underside has short, white spines in a pentagonal pattern. In addition, they have tube feet which help them find and capture prey.

Sea Stars are carnivores and feed on mussels, chitons, limpets, snail, barnacles, echinoid, and crustacea. They also eat zooplankton and phytoplanton. If they are so lucky to trap a prey that is too large to swallow whole, they are able to evert their stomach over the prey and digest it before swallowing.

Predators

Sea Stars have few predators such as sea otters, sea gulls, and human visitors to tide pools and collectors.

If I only had a brain

Sea Stars are a simple organism that does not have a brain. Nerves coordinate activities through nerves that extend around the mouth and through each arm. Each arm has light sensitive cells which help support visual perception. Other perception channels used to communicate include tactile (touch) and chemical.

More than just a pretty face

Sea Stars serve as a keystone species in some communities as a keystone species. They help control mussel populations which will expand to quickly exclude other species.

Sea Stars, through their predation of mussels, balance structure and species diversity in specific communities. Not all communities are affected by Sea Stars.

Next time you see a Sea Star in a tidepool you will know that it is more than just a beautiful unique animal, but also a hard working one as well.

The great wanderer

Peregrine Falcon (Photo courtesy of ODFW)

The word “peregrine” means wanderer or pilgrim. Peregrine is a perfect name for this falcon that lives on several oceanic islands and every continent except Antarctica.

Humans and Peregrine falcons have history. Humans have trained falcons as a hunting partners for thousands of years.

This knowledge and experience became critical between 1950-1970 when populations were wiped out by DDT poisoning. Populations in captivity and handling techniques were used to help re-establish populations and save this species.

After significant recovery efforts, Peregrine Falcon populations have rebounded with an estimated global breeding population of around 140,000.  They are now regularly seen in many large cities and coastal areas, reside in Oregon, and the species was removed from the Endangered Species List in 1999.

Super Bird

Peregrine falcons have such amazing skills they dwarf comic book super heros. To start with they are, without a doubt, the fastest bird alive.

SPEED: General traveling flight is only around 25-34 mph, In pursuit, these numbers dramatically change to nearly 69 mph, with spectacular skydives reaching speeds of 240 mph.

These skydives, called stoops, begin 300–3,000 feet above their prey. The falcon tucks its pointy wings tightly to the body to maximize speed. It then either strikes or grabs the prey hard enough to stun or kill.

HUNTING TECHNIQUES: Other hunting techniques include selecting birds out of a large flock, level pursuit, and ground hunting. If you see a sudden eruption of a peaceful flock, a Peregrine is most likely nearby. Some of the flock may be trying to mob the Peregrine and drive it off.

FLEXIBLE DIET: Prey predominantly includes primarily birds, but can include bats, rodents, fish and prey pirated from other raptors.  Falcons consume over 450 North American species. Worldwide diet choices can run upward of 2,000 choices worldwide.

This can include birds ranging from a large Sandhill Crane to a tiny hummingbird. More typical prey species include shorebirds, ptarmigan, ducks, gulls, pigeons, and songbirds.

FEW PREDATORS: Predators include eagles, Great Horned owls, Gyrfalcons, and other peregrines.

SHARED CHARACTERISTICS: All falcons have some shared characteristics that includes: a conspicuously toothed and notched bill, a nasal cone, and pointed wings which may span over 44 inches.

Nesting

It is not unusual to find a 24/7 camera poised on a Peregrine falcon nest perched on a tall building in the city.  Peregrines will perch and nest on any open tall structure such as a skyscraper, water tower, power structures, bridges, rim of the Grand Canyon, in trees on steep slopes, and more.

They typically create a nest about one-third down the cliff face anywhere from 25 to 1,300 feet high. The nest itself is pretty minimal ‘scrape’ about nine inches across and two inches deep. 

In a pinch, falcons will select abandoned nests created by other birds such as, Bald Eagles, Osprey, Red-tailed Hawk.

Superstar Chicks

At birth, this baby is entirely helpless with closed eyes. Yet, the tiny falcon chick will work up to 36 hours to peck free of it shell. This amazingly, difficult process has been the focus of many morning  falcon-cam programs. 

Juveniles have many vertical bars on their breasts. Adults also have the barred under breast, with blue-gray feathers above and a dark head with thick sideburns. This barred look is standard across all ages and geographic variation.

Where to find them

Peregrines inhabit open landscapes from tundra to deserts when not nesting. Areas include coastlines, barrier islands, lake edges, mudflats, and cliff sides. They may also be found near concentrations of prey, such as Rock Pigeons.

Peregrines in the Arctic tundra will migrate to South American earning their high mileage discount by covering as much as 15,500 miles in one year.  Their sharp homing instinct will lead them back to favored nesting spots which may have been in continuous use for hundreds of years, by successive falcon generations.
