The Hawks and Eagles of Orange County


Please note that as always--unless otherwise specified--all these pictures are copyrighted by Karen McQuade, the OC Birder Girl.

Hawks and Eagles

In raptors like hawks, eagles, and owls, the female is bigger than the male.   Raptors grab prey with their feet.   The word "raptor" comes from a Latin word  meaning "to seize."  If you want to see a wide variety of raptors, go to open country--especially in eastern Orange County.   Other open areas to see raptors are large parks or wildlife areas like Seal Beach National Wildlife Refuge, Upper Newport Bay, Huntington Central Park, Bolsa Chica Ecological Reserve.   On the latter, note that Huntington Central Park and Bolsa Chica are actually connected by open space which includes oil fields not currently open to the public.  However, the birds--especially raptors--treat any area like this as one large, open area and move readily between any similar habitats.    So even though a park may be small or moderate size, it depends on the larger area around it as to what raptors it may attract.


Eagles

Bald Eagles

Bald Eagles are considered rare in Orange County, but there are regular sightings in Fall and Winter.  No nesting records.


Mature Bald Eagle in Prentice Park Zoo

Mature Bald Eagles have a solid white head and tail, dark body and wing feathers and a large, yellow hooked beak.   They are considered rare birds in Orange County, but are seen regularly over lakes, rivers, and other bodies of water

Unmistakable when mature, the immature Bald Eagle looks splotchy.  Unlike the immature Golden Eagle which has neat patches of white, the immature Bald Eagle's white looks random and messy.

Though Bald Eagles are rare, they have appeared regularly during fall and winter in Orange County in areas with open space, rivers, and lakes with fish.    There have been occasional sightings at other times of the year.    As you might expect, Bald Eagles are usually spotted near lakes and rivers.    Bald Eagles have been seen in areas such as Irvine Regional Park, Peters Canyon Regional Park, Seal Beach at the Wildlife Refuge on the marine base, the old El Toro Marine Base now the Great Park, Irvine Lake, and other areas near or on the way to rivers or large lakes.    Although they nest in many counties around Orange County such as San Bernardino, Ventura, San Diego, and Riverside counties, there have been no recent nesting records actually in  Orange County.



 

Golden Eagles


Orange County Zoo in Irvine Regional Park.

Rare, Golden Eagles are usually seen over open country in Orange County.   They have been regularly seen in the east county area in the rural areas of the City of Orange, Irvine, and south Orange County areas in addition to rarer sightings in other parts of the county.   The most frequent sightings reported over the years are at El Toro Marine Base aka now as the Great Park,  in Mission Viejo, and at O'Neill Park.

Note the that the cowlick of feather sticking out at the back of the head.  This is common to all Golden Eagles. 

Immature Golden Eagle shows patches of white as opposed to the random white splotches of the immature bald eagle.  Photo courtesy of US FWS.  Photographer Donna Dewhurst.



The immature Golden Eagle can be mistaken for a Bald Eagle with its white wing patches and white tail base.   Note though that unlike the mature Bald Eagle, it has a terminal black band on its tail.   It can also be mistaken for a California Condor by the inexperienced viewer.   See details to consider when making an identification of a California Condor under the section regarding California Condors below.

Buteos

Buteos have long, broad wings and a short fanned tail which allow them to ride  thermals up into the sky and soar for long periods of time with little to no flapping.  They ride the wind and watch the ground for tasty prey.  Extremely common in Orange County.  It seems like every park or freeway off ramp has one perched on a tree or street light.  Nests in Orange County.





Red-tailed Hawk flying with no red tail showing.  Belly band and patagial bar on the leading edge of wings are easy to see.



The same Red-tailed Hawk flying with the sun behind him or her, clearly shows a red tail and the patagial bar on the leading a edge of the wing, but the belly band is not so easy to see





Mature Red-tailed Hawk with prey at Mile Square Regional Park.

I took this shot at the lake without the island at Mile Square Regional Park just about an hour before sunset.  This Red-tailed Hawk had just killed a duck.  Red-tailed Hawks are very strong.  It actually grabbed the duck in its talons and flew off with it.  Its red tail is barely visible here--hidden under the long wings.   

Red-tailed Hawks have many morphs.   The Red-tails here are the most common Orange County variations.  For other morphs check my post Red-tailed Hawk Morphs.

Broad-winged Hawk

Occasional sightings in Orange County in the fall and winter.

Harris's Hawk

Rare in Orange County.




This is a photograph I snapped during a bird show at the San Diego Wild Animal Park.    Rare in Orange County.   Note rufous shoulders, and tail with white base, black stripe, and terminal white band.

Note that Harris's Hawks travel in pairs or groups, and often hunt together.  National Geographic calls them "the wolf pack of the air."

Red-shouldered Hawk

Fairly common in Orange County in wooded areas such as Santiago Oaks, Irvine Regional Park, and Huntington Central Park.   Nests in Orange County.

Red-shouldered Hawk I snapped in Crestline.


Same Hawk, spotted wings showing.   The thick stripes on the wings show up as spots when the wings are folded.



Stuffed Red-shouldered Hawk at Irvine Regional Park Nature Center shows stripes in partially extended wings.

Although a blurry shot, you still can see the broad, black-and-white stripes in the tail and the wings and the rufous breast.  No thin barring like the Cooper's Hawk, but bold, thick stripes.  Taken at Irvine Regional Park.


Red-shouldered Hawks, though Buteos, are hawks of the forest and oak woodlands.  They are also one of the noisiest hawks we have.  I usually hear them before I see them.   They are reddish brown with a thickly striped black and white tail and wings.   With wings folded as they perch, they have rusty shoulders and spotted wings.  You can see them in parks with lots of trees like O'Neil Regional Park, Irvine Regional Park, Huntington Central Park,  Santiago Oaks Regional Park, and others.



Sometimes called the "fish hawk," Osprey live almost exclusively on fish, but do on rare occasions eat smaller birds, lizards, or amphibians.    Very common in Orange County.  Even stocked ponds and small lakes in Orange County city parks get a bit of attention from Osprey.  Several nesting pairs in Orange County.



One of two nesting Osprey at San Joaquin Wildlife Sanctuary



Osprey at Tewinkle Park a few years ago.  They often take advantage of small lakes at Orange County parks such as Tewinkle ParkHuntington Central Park, Mile-square Regional Park, Carr Park, and other parks with fish in their relatively small lakes.  They can also be seen at wetlands and along Pacific Coast Highway where they have a choice between the ocean and several wetlands.

 I took this picture at Mile Square Regional Park.  Notice that there is a bend in the wrist of the wing.  This is a good field mark for identifying Osprey

Again, from Mile Square Regional Park.  Notice the bend in the wing.  
 

Northern Harrier

Uncommon, but regularly seen in Fall and Winter in Orange County in areas near water such as Bolsa Chica Ecological Reserve, Upper Newport Bay, and Crystal Cove.


 The Northern Harrier female is brown with a white spot on the rump.   This female Norther Harrier above sits out in the marsh at Upper Newport Bay.   The Northern Harrier commonly sits on the ground to eat or rest.   The male is gray and white with a white spot on the rump.

Northern Harrier female.  The white at the base of the tail is an easy field mark to spot in either male or female.  Courtesy of Wikicommons.  Photographer Dan Pancamo.


The Northern Harrier is often first seen hunting over a marsh or wetlands or near the ocean.   The white spot at the base of the tail is the most obvious field marking.    The female is brown and the male is gray.   They have round disks on their faces that are very like an owl with the same purpose--to direct sound to their ears.  They hunt by sound and by sight.  Their long legs hang down as they fly.





White-tailed Kite

Regularly seen year round, uncommon, but sightings are increasing.  Nests in Orange County, but nesting numbers went down for a few years.  Seems to be recovering slowly.   Seen at Bolsa Chica Ecological Reserve, Santiago Oaks Regional Park, San Joaquin Wildlife SanctuaryHuntington Central Park, Mason Regional Park, and Orange County regional parks, open areas, the Santa Ana River, and freeway off ramps.  Nests in Orange County.


White-tailed Kite hovering over parking lot at Bolsa Chica Ecological Reserve.   Seen in the open country, but also in parks and by freeways exits and entrances.    This is a common hunting method for White-tailed Kites.

Falcons


Merlin

Uncommon in Orange County, but there are some regular sightings at Bolsa Chica Ecological Reserve, San Joaquin Wildlife Sanctuary, and some of the regional parks in the area.

Peregrine Falcon 

Uncommon in Orange County as a whole, but may be seen regularly in certain spots like Bolsa Chica Ecological Reserve and regional parks, the Santa Ana River and other areas.

American Kestrel

Fairly common in certain areas.  Nests in Orange County.

 American Kestrels are tiny hawks that eat insects, lizards, small mammals, and birds.  Here, a male eats a large insect in a tree on the Bolsa Chica Ecological Reserve mesa.   



 Colors really showing on a male American Kestrel .   Photo courtesy of US FWS.  Photographer unknown.


 The female American Kestrel is browner without the slate-blue wings and cap and does not have a bright rufous tail like the male.  They tend to hover in flight looking for prey.    It is not uncommon for them to be perched on a dry branch scanning the ground for prey.  This one looks down from the mesa at Bolsa Chica Ecological ReserveYou will also see them at San Joaquin Wildlife Sanctuary, Upper Newport Bay, Santiago Oaks Regional Park, and many other locations.   I saw one in Cypress, CA swooping down onto a lawn in a business area, and in a residential area in Costa Mesa. 





Accipiters

Unlike buteos, accipiters do not soar, but instead zip among trees in the forests and woodlands and neighborhood foliage in pursuit of prey.  These hawks are built for maneuverability and speed.   I recently was walking down a path at Mile Square Regional Park Nature Center when an accipiter came barrelling down the narrow, shrub-lined path about two and a half feet off the ground.  It quickly swerved around me and sped down the narrow trail.  The first two accipiters listed here are are almost impossible to tell apart because even though the female Cooper's Hawk is bigger than the female Sharp-shinned, the smaller male Cooper's Hawk and the female Sharp-shinned are much closer in size.    Both mature Cooper's and Sharpies have slate gray heads and red eyes.  The Sharpie has skinny little legs compared to the bigger, thicker legs of the Cooper's.  Like all Accipiters, they have short, rounded wings and long tails. 



The Cooper's Hawk is very common in Orange County year round.  Nests in Orange County.





Adult Cooper's Hawk seated in the trees above the ducks and coots at Huntington Central Park near the old Alice's Breakfast in the Park.   He was selecting his or her own breakfast.





Mother Cooper's Hawk watching over her rather partly downy covered fledglings.    The smaller Dad was not far away.

Juvenile Cooper's Hawk snapped by me in the fenced garden behind the Huntington Central Park.   Notice the eyes have not yet turned red like the adult Cooper's Hawk.

Uncommon.   Very similar to a Cooper's Hawk, but smaller.  However, the male Cooper's Hawk and the female Sharp-Shinned may be a bit closer in size.   The Sharp-shinned has very skinny, frail-looking legs compared to the more substantial legs of the Cooper's Hawk.  The Sharpie's tail has square corners and a thin white tip while the Cooper's has round corners and a thick white tip.  To tell the difference between Cooper's Hawks and Sharp-shinned Hawks, check out this excellent link from Cornell Lab of Ornithology's FeederWatch pages Identifying Cooper's and Sharp-shinned Hawks.

Other Raptors or Vultures

Owls


 


Vultures






Turkey Vulture in flight with classic two-toned wings.   The trailing edge of their wings is very light gray or white.     They have a large wingspan.   They have a bare, red head.




Turkey Vulture cooling off at the Orange County Zoo in Irvine Regional Park.





Turkey Vulture in cage at the Orange County Zoo Irvine Regional Park.


Turkey Vultures are very common in Orange County soaring over the parks, wilderness areas, open spaces, and freeways.   They are pretty much everywhere ready to clean up the county of dead animals.  




California Condor



Endangered and rare, California Condors have not had any verified sightings in Orange County, but there have been a two very recent unverified claims to have seen California Condors in Seal Beach and Costa Mesa, and so I am including them for assistance in differentiating the California Condor from other similar birds in Orange County.

California Condor stretches its wings in its cage at the San Diego Wild Animal Park.



Unlike the Turkey Vulture who has a skinny, red head, the California Condor had a multicolored, puffy head.  Also unlike the Turkey Vulture, there is a patch of white toward the leading edge of the wings. 



Close-up of the puffy multicolored head.







Mature California Condor in flight.  The white is on the leading edge of the wing near the body.  The tail is dark.  Photo courtesy of Wikicommons.  Photographer Phil Armitage.  Here is his website  http://www.philarmitage.net/zion.html.     

Compare with the immature Golden Eagle which shows patches of white further back on the wing and away from the body.   The white tail has a terminal black band.  Notice also the difference in the color, shape and size of the head.  Photo courtesy of US FWS.  Photographer Donna Dewhurst.





 Turkey Vulture in flight.  Note the extremely small head.   The primaries and secondaries of a Turkey Vulture's wing are grayish white.  The tail is dark.  Photo courtesy of Wikicommons.  Photographer Dori.  Altered by Snowman Radio.

Please note that the Golden Eagle is smaller and has a large, dark head, and a white tail with a terminal black band.    The Bald Eagle is also smaller, and  has a larger white head and a white tail.   The smaller Turkey Vulture is dark with a smaller black or red head and two-toned wings seen from below--not patches.  The trailing half of a Turkey Vulture's wing is grayish white as opposed to the California Condor's clean, white patch in the leading area of the wing near the body.   So pay attention to color and where on the wing the light color is and size.  Also note that the California Condor is much larger than the Turkey Vulture.  The California Condor's wingspan is about 9.8 feet as compared to the smaller wingspan of the Turkey Vulture which is 5-6 feet.   

A California Condor will look huge and almost certainly will be tagged because they are endangered and very closely monitored.   However, remember a large vulture with a tag could also be a Turkey Vulture.  Turkey Vulture populations are being monitored by tagging them as well.   So that should not be a deciding factor.    A tagged vulture could be either, but an untagged California Condor should be carefully observed, and the details noted to verify your sighting because an untagged condor would be extremely unlikelyTake pictures of any California Condor sighting if you can.  Make notations as to the location and time.   Since there are no verifiied sightings in Orange County, California, your sighting will be looked at with skepticism until verified.

Great blog I stumbled upon it while searching for info about Bald Eagles in Orange County. In March of 2012 I was lucky enough to see one while out on a hike near Irvine Lake. Got to see the nest and what appeared to be 2 young juveniles in the nest. It was an awesome sight

Thanks for stopping by and commenting. I hear Irvine Lake is a great place to see Osprey and the occasional Bald Eagle.

What a great blog! While hiking on the Red Rock Canyon Trail in Whiting Ranch (Foothill Ranch) I saw a huge nest up high on the red Rock Cliffs. I tried to zoom in on it with my camera, it was up pretty high. It was a very large nest and appeared abandoned. I'm trying to identify it. Googled pictures and it looks like an eagles nest, but I'm not sure. Any suggestions for identifying it? I'm not even sure if Eagles are seen in this area.

Thank you for stopping by, and the kind words. As to your question regarding nest identification, that can be tricky. Golden Eagles nest in remote areas of Orange County. There are no records for Bald Eagles nesting in Orange County in recent years. Many non-birders mistake Osprey for Bald Eagles. Bald Eagles nest in trees of high up on cliffs or similar sites. Here is an article you might find helpful from the OC Register http://www.ocregister.com/articles/golden-497465-eagles-bloom.html
You will notice that the article mentions that there are Golden Eagles in the area in Modjeska Canyon. Golden Eagles will nest on cliffs as well as in trees. Nests are made of branches, sticks, and twigs with the inside of the bowl covered with more comfortable things like leaves, grass, and other soft vegetation. Red-tailed Hawks prefer nesting in a tree among other trees, but will build on cliffs, ledges on buildings (as Pale Male in New York City). Tree twigs, sticks, leaves may be part of a Red Tail's nest. The Osprey usually builds very near water on a tree or if safe, a flat surface and even nesting platforms constructed for them. Their nests are made also of sticks. Turkey Vultures nest in the nests of other raptors, or build their own messy nests of leaf and other litter. Mainly just a pile of litter with a depression. They can nest on a cliff among the rocks. Thanks for stopping by.

Excellent blog... thank you for this! :) We were sure that we continue to see a California Condor, feeling very special to see such an endangered bird. We now learn that it is a golden eagle (identical to the picture you provided.) Thank you for setting us straight! :)

Take care!
