Northern Pintail--Anas acuta

Northern Pintails at Newport Back Bay

Northern Pintails are the Audrey Hepburn of duckdom. They have long necks and a graceful bearing. They are much more slender than the Mallard. They are not as common in parks as Mallards and American Wigeons. They are more a of a wild bird. Nothern Pintails are not endangered, but they are declining. They breed in the Alaska and in the grasslands of Northern America. Like other birds who breed in these areas, they are facing loss of habitat.

The Northern Pintail seems deceptively easy to ID. However, if you only know it from the picture in the guide book, it is easy to overlook. The Northern Pintail's white neck stripe can appear very different depending on how it is swimming, standing or flying. Sometimes you can't see it at from your viewpoint, so if you depend on the white neck-stripe alone, you will miss it often in the field.

Field Marks to Look for:






  • Long, graceful neck


  • Long, pointy tail


  • White chest


  • Dark Bill


  • Chocolate colored head


  • White line that goes up the side of the neck





Bottoms up.

A Northern Pintail is a dabbling duck, so sometimes all you see is a feathery tail sticking out of the water. This can go on for a long time as they come up quickly for air and go back down again. Note the long, pointy tail. They eat aquatic plants, crustaceans, snails, grain, insects, and lots more.



Sometimes you can't see the head or chest.

Get to know the Northern Pintail well, and you won't often miss it in a crowd of ducks.



Sleeping Northern Pintail at Bolsa Chica Ecological Reserve.

When a Northern Pintail tucks its head back to go to sleep, the white line can look like the little peak on a meringue cookie. See above and below. If you can see the tail, that is another field mark to notice. If not, you see something like the Northern Pintails below.

From behind you see two stripes like the photo above.

And sometimes, depending on the viewing angle, you may not see the white line on their neck at all.

Get familiar with how a Northern Pintail looks from different angles. Get familiar with the way its tail looks and its silhouette.

Northern Pintails are seen in marshes, estuaries, farmland, grasslands, wetlands, and inter-tidal marshes. So if you are birding in winter in one of those areas, look around. If you see a slender duck with a white chest, take a closer look, you might see a Northern Pintail.








Below is a video I took at Bolsa Chica Ecological Reserve by the footbridge.

The Birds of Bolsa Chica Versus Brightwater's Wall of Glass

Forty or more concerned people gathered to view and discuss the Glass Wall

The Meeting

On Saturday 11/24/2007, with very short notice and with very little publicity beyond a website notice, Audubon's Conservation Director Scott Thomas expected only a handful of people to show for this gathering about Brightwater's glass wall. Instead, on a holiday weekend, 40 or more people showed up to view the long, glass barrier. (I am an Audubon member, and I happened upon the announcement on the Sea and Sage Audubon Website.) Because of prior complaints, Hearthside put a chain link fence with pieces of yellow plastic tape tied to it behind the wall to try to prevent birds from flying into the glass. We all appreciate their responsiveness and applaud their first attempt to solve this problem.




It's big. It is 6 feet high and 4,400 feet long. Walk it yourself. Wear comfortable shoes.

The Problem

LA Times writer Tony Barboza wrote an excellent article entitled "Glass wall has birders seeing red." So what has us birders in such an uproar over the Wall of Glass which some people call the "Wall of Death?" This wall is part of a much larger problem which has come to light over the last few years. The problems is that we humans love a good view. Nothing wrong with that. But the problem is that birds, trying to make sense of what they see, collide with the glass windows and die by the millions every year.



Part of the Beautiful View Hearthside is selling to its homeowners.

Many tall buildings are now seemingly made of glass. We get great views in the office and don't feel all cooped up in a box. But large panes of glass, along with several other modern amenities, are having a serious impact on birds. Because glass reflects the sky and trees and everything opposite it, it looks pretty against the skyline. Birds mistake it for the sky or whatever is being reflected, or they try to fly through it to the inside. At one place I worked an American Robin drove himself crazy attacking a rival American Robin reflected in the glass every time he flew up to the building. He would throw himself at the image. At another office workers found a stunned and unconscious Rufous Hummingbird on the sidewalk by the glass windows.


More of the wall

The US Fish and Wildlife Service has a great brochure called "The Danger of Plate Glass: Understanding and Avoiding That Painful Thud" . This article mentions the incredible toll that panes of glass have on birds each year: An estimated 100 million to 1 billion birds a year. The Audubon Society Magazine article Clear and Present Danger talks in depth about buildings and the steps developers around the world are making to minimize the impact of structures on birds. The New York and New Jersey Port Authority in their article PORT AUTHORITY TAKES STEPS TO PROTECT MIGRATORY BIRDS AROUND WORLD TRADE CENTER stated that in about a two-month period, in 2000 the New York City Audubon Society documented almost 500 dead or injured birds found in the area of the World Trade Center and nearby buildings in the year before 9-11. As small as that is compared to the awful act of terrorism that occurred there, it is evidence of the problem of glass for birds. In addition, the City of Toronto is so concerned about the problem of development affecting birds that they have come out with a lengthy brochure that includes a large section on plate glass and how to protect birds from flying into it: "Bird Friendly Development Guidelines." Pages 7-18 has a long and detailed discussion of solutions for glass windows killing birds. The site Birds and Buildings lists many details about the problem and some of the many solutions that are being tried worldwide. This brochure is part of the City of Toronto's Green Development program. New York Audubon has the Bird-Safe Building Guidelines. Daniel Klem, Jr. of Muhlenberg College in Pennsylvania has studied this phenomenon See his paper BIRD-WINDOW COLLISIONS and
COLLISIONS BETWEEN BIRDS AND WINDOWS: MORTALITY AND PREVENTION and CNN coverage "Glass windows an 'indiscriminate' bird killer."



Walking the wall.

That glass and birds don't mix is a fact, and that glass near a wildlife sanctuary with thousands of birds is an extremely dangerous mix is obvious. There are two endangered species at Bolsa Chica: the California Least Tern and the Belding's Savannah Sparrow. Hearthside has lots of money invested, and with so much at stake, one can understand and empathize with their desire not to overreact needlessly. However, Sea and Sage Audubon and others are not imagining a problem or exaggerating one, or pulling one out of their hat. It is a problem to build a wall of a material that--depending on the time of day and weather conditions either disappears or reflects the sky and plants outside the glass.--and to build it near thousands of animals with a documented problem of being injured by flying into just such glass. It's not rocket science. The Cities of Chicago (Chicago Bird Collision Monitors, The City of Chicago's A Bird's Eye View Website), New York, Toronto, and others world wide recognize the problem as does the US Department of Fish and Game. It is a problem. And that's a fact--unpleasant though it is after so much money was invested by developers in Brightwater's glass wall.

Just a small portion of the wall.


Obviously, the chain link is not the permanent solution. Is the building of the homes going to prevent birds deaths as Ed Mounford, the Senior Vice President of Hearthside, hopes? I wish, it were, but I do not think so. In my humble opinion, and the opinion of many others, here is why:


Reflection of trees out in the Bolsa Chica Ecological Reserve in the Brightwater Wall of Glass.


The Problem of Reflection

As many people have said a lot of the problem is what's outside, not what's inside. The reflection of habitat outside the glass confuses birds into flying into the glass. If you walk along the path that borders the glass wall, it's obvious reflection is a problem. Building homes inside the glass won't change the way the lighting causes reflection of the Bolsa Chica habitat outside the glass. When the light is right, it will become a mirror. In the picture above, you can clearly see that these trees are not behind the glass as they appear to be because the image stops when the glass stops.


Inviting trees being planted in the yards of model homes behind the Glass Wall.



The Problem of Transparency


If you walk the path outside the glass wall, you will also notice that you can see through it. No big surprise, since glass is made to be seen through. But it is when you get to the models and look into the yards that you realize there is a whole other problem. These yards are going to be landscaped. That means trees and shrubs and nice places to perch. And water from sprinklers and people watering their lawns. So yes, when the light is right, the birds will see the houses, shrubs, trees, lawns, water, and nice places to sit. And then they will attempt to reach those attractive things through the glass and collide with it.




Lots of nice patio cover to perch on. Flying up to it could be fatal.




The Problem of Lights at Night

There are few prettier city sights at night than the lights of the city. When the homes are built, the lights at night will be pretty for them as they look through the glass wall toward the sea. However, for the birds, the lights from Brightwater will be a deadly beacon. The City of Chicago discusses it on their website. Click here to see the article. See the article in Audubon Magazine The Dark Side of Light for more detailed discussion of similar problems. The lights on in the homes of BrightWater will shine through the glass wall and may well cause migrating birds and other birds problems.





One of the many places you can see a significant change in elevation of the wall compared to the surroundings.


Change in Elevation

Problems with the Change in Elevation

The wall is much higher than the surrounding land in some areas. It was pointed out by Audubon Conservation Director Scott Thomas that this may be a problem. Birds, flying above the ground straight across at an elevation they think is safe, will in fact be flying too low and hit the glass.


More Inviting Foliage to fly into.


In Conclusion

When a developer moves in next to a treasured ecological reserve, it is incumbent on the developer and all government agencies to ensure that the development is a responsible neighbor. All planning should start with a concern for the environment that they are abutting. I would hope that as the development is annexed to the City of Huntington Beach the city will make sure all plans consider the well-being of the Bolsa Chica Ecological Reserve and that all discussions include, not exclude local environmental groups. Many developers and businesses do take the environment into consideration and are the better for it. Hearthside would be in good company if it would listen to and learn from the experts in the Bolsa Chica and the environment. The experience of cities worldwide should show us that neither a chain link fence nor a home with a backyard full of trees and shrubs are the solution to the Wall of Glass. After you look at the evidence, it is clear that much more needs to be done. Let's all work together to find a solution that benefits us all.

If you find any injured birds at the Wall, please contact the Wetlands and Wildlife Center. For more detailed instructions regarding dead or injured birds, see Sea and Sage Audubon's page on the Glass Wall. Take photographs of any dead or injured bird and include the wall. To reach the wall, take Warner to Bolsa Chica, and turn south. Park on Bolsa Chica or a side street. Walk down Bolsa Chica Street away from Warner and through the Brightwater arch. Continue until you enter the Bolsa Chica Ecological Reserve trail. Bolsa Chica Street actually becomes the trail. The wall will be on your right. You can't miss it.

Update 12/02/2007: Hearthside has pledged to take a new step to ensure the safety of birds. Decals, 1,500 of them. Is it enough? Stay tuned for more informaton. See the article below under Newspaper Articles.

You can check their current meeting agenda to see if any issues of concern are on it. Or check past agendas for areas of concern. Here is a link to a 2005 Sierra Club analysis of the Commission and its voting record. Very interesting.

We are the South Coast Area. Here is a list of organizations concerned with coastal issues in Orange County listed by the Commission: Marine, Coastal & Watershed Resource Directory

Here is a list of the Commissioners. Please note two things. One, there are no commissioners from Orange County. There are some from Los Angeles which is part of our South Coast District, but none from Orange County. Two, there are strict rules for communications with the Commissioners. Scroll down to the end of their page after the list of commissioners to read "EX PARTE COMMUNICATION REQUIREMENTS."

California Coastal Commission and the BrightWater Project

Here is the meeting in which the wall was approved and the document regarding the glass wall which is referred to as "plexiglass material"--it reads:

"Rear yard walls on the residential lots abutting the Eucalyptus Grove and burrowing owl ESHA buffers shall not exceed a total height of six feet above finished grade shown on the approved final grading plan. The lower two feet of the rear yard wall shall be on concrete
material
and the upper four feet shall be of plexiglass material. Future development shall conform to these heights and setbacks unless such heights are changed by an amendment to this permit, unless the Executive Director determines that no amendment to this permit is required."
APPLICATION NUMBER: 5-05-020 (Brightwater) page 45 item 21b (Note that the italics are my emphasis.)

I don't see an amendment to that permit--perhaps I missed it--and after seeing the wall, I wonder if it actually is "plexiglass material" and actually meets the height requirements. What is the legal definition of "plexiglass?" I don't know, but most definitions I have seen say plastic or acrylic. The material the wall is made of seems to be safety glass and the height of the glass seems to be 6 feet all along the wall not 4 feet at in any section. I wonder what permits other than the Coastal Commission permit they were required to get. Also, exactly what do the environmental impact reports say? There must be an Orange County Building permit filed for the grading, the retaining wall, and the glass wall. What do the OC planning staff reports actually say? Does the permit from OC have to match the one from the Coastal Commission and any other documents filed? Does one superscede the other? I think all the county documents must be on file at the county. I also wonder what the requirements the City of Huntington Beach will have before the annexation of the land. I hope they will be addressing any aspects of the project that are a danger to the wildlife of Bolsa Chica. I think all the documents filed so far should be examined carefully by as many people as possible.

Turkey Vultures--Cathartes aura

Turkey Vulture in flight courtesy of the US Fish and Wilflife Service

When my big brother was a boy, he had to write a report about a bird. Being a boy, he could not pick a warbler or hummingbird. Nothing pretty would do. No foo-foo birds. He had to pick a manly bird, and if it were gross, all the better. He picked the Turkey Vulture. It fit all the requirements.


Turkey Vulture at the Orange County Zoo in Irvine Regional Park

Turkey Vultures are related to storks according to scientists. They have a 6-foot wingspan and look mighty big when you are hiking and see them looking down at you. They soar so high that you generally need binoculars to get a good look at them. Even so, it is not a very close look. If you see them perched in a tree, you might get a closer view. The shot above and others from the Orange County Zoo in this post are photos that I took on a recent visit. It's not often you can see a Turkey Vulture so up close and personal. I took these pictures with a 12x zoom.



Turkey Vulture at the Orange County Zoo in Irvine Regional Park

Vultures are the janitors of the bird world. Something dies, and they clean it up. They can eat the grossest things and not get sick. They are specially designed for this job. First, they are good at spotting carrion (dead animals.) They have the best sense of smell in the bird world. They can smell carrion from a long way off. In addition, their eye sight is excellent.






Turkey Vulture at the Orange County Zoo in Irvine Regional Park

Their digestive systems kill bacteria and by the time it comes out, it is much cleaner than when it went in. This also why they can eat rotting meat. They are like a large, ugly disinfectant. Pretty amazing, really.





Turkey Vulture at the Orange County Zoo in Irvine Regional Park

In flight, the Turkey Vulture is beautiful. Its wings are large and two-toned. The trailing edge is light gray. It soars with its wings in a slight v-shape. It tilts from side to side at times. The Turkey Vulture reaches speeds of 60 miles an hour when soaring, looking and smelling the air for food. It is often confused with hawks by people who are not familiar with the Turkey Vulture.

Turkey Vulture at the Orange County Zoo in Irvine Regional Park

Where can you find Turkey Vultures in Orange County, California? Just about everywhere. Over the freeway, over open fields, nature centers, ecological preserves, parks, and anywhere there are places to soar and things to clean up. I have seen them over Bolsa Chica, Central Park, San Joaquin Wildlife Sanctuary, Santiago Oaks, Newport Back Bay, the 405 freeway, Crystal Cove, Irvine Park, Mason Regional Park, over an industrial business area in Cypress, along many places along Pacific Coast Highway, and many, many more places. Look up in the sky for the two-toned wings held in a shallow V. I am sure you will see it soaring near you sometime soon.

Marbled Godwit--Limosa fedoa

Marbled Godwit at Bolsa Chica Ecological Reserve

The things that I really like about the Marbled Godwit are its two-toned pink, black tipped bill, and the intricate brown-and-white pattern on its body. It's a very interesting looking bird. It winters on here and come breeding season heads to the center of the United States and Canada to breed in grasslands and prairies.
Marbled Godwit at Bolsa Chica Ecological Reserve.


There is a whole program called Godwits on the Go that tracks the Marbled Godwit to see where it is spending its time. There is lots of concern about the Marbled Godwit with both loss of wintering and breeding habitat. It is hoped that by tracking them that information will be found that will help us ensure that Marbled Godwits survive and thrive in the Americas.


Marbled Godwit at Bolsa Chica Ecological Reserve.


The Marbled Godwit is one of many shorebirds, but its pink-and-black bill set it apart from rest. With its pretty, just slightly upturned bill, it eats many squiggly and squishy things like worms, aquatic insects, crustaceans, and other things it finds in the grass, mud or wet beach sand. In addition to seeing them at Bolsa Chica Ecological Reserve, you will see Marbled Godwits across the street at Bolsa Chica Beach and other Orange County Beaches.




Marbled Godwit in the wet marsh vegetation at Bolsa Chica.

Although the sexes look almost the same, the female Marbled Godwit is larger than the male. The intricate pattern on the back resembles several other shore birds, but none has the black tipped pink bill of the Marbled Godwit.



Marbled Godwit concentrating on the buffet at Bolsa Chica Ecological Reserve.

You can find Marbled Godwits in shallow water, mud, in grass, or on the beach. Next time you are birding, look for a Marbled Godwit and watch it probe the mud or sand with its sturdy bill looking for squiggly, squishy treats.

Eared Grebe--Podiceps nigricollis

Red-eyed, bushy-tailed and ready to rumble with some fish.


Eared grebes are common in fall and winter. In spring, we don't see them so much as they head off to the breeding grounds. Eared Grebes are fluffy-looking grayish black-and-white water birds with red eyes and a slight upward lift in their bill.


Eared Grebe at Bolsa Chica, Copyright Karen McQuade, OC Birder GirlEared Grebes are small black-and-white birds that swim in the water and dive rather suddenly.


Eared Grebe at Bolsa Chica, Copyright Karen McQuade, OC Birder Girl Eared Grebe cruising at Bolsa Chica in low-key, winter plumage.


Notice how high his fanny rides in the water. That is characteristic. According to "All About Birds," it likes to sun its fanny and warm up that way.







Characteristic of my early shots of Eared Grebes.

For the longest time, the only shots I got of eared grebes were of ripples in the water where they had been seconds before. It takes timing and patience--especially when eared grebes are on a diving roll. An Eared Grebe comes up from one dive and then dives down again faster than a birder can blink. What you do is find some grebes. Then you wait, snapping away until you get the right shot.

Sometimes you can catch them after a long session of diving when they just cruise along and rest up for the next diving set.



















Underwater footage of unidentified grebe by Thomas Lockie.



Here from You-Tube member Thomas Lockie is a great video of an unidentified grebe diving. Notice the way his feet are set back on his body and act as a kind of propeller powering him through the water.

Eared Grebes eat brine shrimp, aquatic invertabrates, crustaceans, and I have seen them chase small fish at Bolsa Chica.

Their feet are set way back on their body so they can power paddle under water when they dive.





Eared Grebe in winter plumage copyright Karen McQuade, the OC Birder GirlEared Grebe is non-breeding plumage. This is how they usually look in the OC.


A low-key bird in fall and winter that draws attention by diving, not looks. Changes a lot when spring comes. Take a look below.

Eared Grebes are kind of like Clark Kent and Superman. They can look very mild mannered and nondescript, but then they don their breeding plumage, and they are flashy and eye-catching. Don't expect to see much of them in this plumage, because they don't breed in Orange County.

Wilson Bulletin: Conspecific Collisions Can Precipitate Mortality in
Migrating Eared Grebes


According to the article, Eared Grebes are nocturnal migrants and not very good navigators. They crash into one another and into stationary objects at fairly low elevations when disoriented by poor weather such as winds, snow, and rain. They are very disoriented by lights. When these conditions exist, collisions increase.
