Terns at Bolsa Chica

Elegant Terns galore! In late spring and early summer, one of the birding spectacles in Southern California is the colony of terns at Bolsa Chica Ecological Reserve in Huntington Beach, Orange County. The pretty estuary (as its name translates from Spanish) has been host to twelve species of terns, with Common, Royal, Caspian, Gull-billed, Black, breeding Black Skimmer, Forster’s, Least, and Elegant, and rarities Sooty, Sandwich, and Bridled.

The American White Pelican (Pelecanus erythrorhynchos) is one of two species of pelican in North America, along with the Brown Pelican (Pelecanus occidentalis). While occasionally seen in the same locations, American White Pelicans and Brown Pelicans prefer different habitats and their manner of feeding is as different as their plumage.

Olive-backed Pipit

Christmas arrived early in Orange County this weekend. Jeff Bray, a local birder, made the find of a lifetime: an Olive-backed Pipit (Anthus hodgsoni). Jeff found this bird at Yorba Regional Park. It may not sound like much, but it’s a really big deal.

Olive-backed Pipit – Previous Continental Records

For starters, there were only 3 previous records of this species in North America away from Alaska. (Here, we define North America geographically as including Mexico – not the birding definition). Washoe, Nevada hosted the first continental Olive-backed Pipit in 1967. Subsequent records came from Baja in 1996, and on the Farallon Islands in California in 1998. So the take-home message is, these guys don’t show up very often! Whenever a call like this goes out, birders do their version of a ‘flash mob’! The Yorba Regional Park mob on Saturday was very impressive!

I was among the first 20 birders there, but soon birders began arriving from all over the map in minutes. And soon it was a who’s who of southern California birders. And why not? This little Olive-backed Pipit really put on a show! It led us a merry dance at first, flying from place to place within the park. Frequently, it landed in heavy cover and skulked around. Sometimes the only visible indication it was there was movement of the vegetation it was walking under. But eventually, it came out on the lawn between the picnic tables and fed calmly for about an hour. Everyone there got crippling looks! In fact, the bird was remarkably cooperative, seeming oblivious to the camera shutter whir and quiet conversation of excited birders. Continue reading

Dance of the Reddish Egret

Reddish Egret preening

Reddish Egret preening

When people find out I’m a birder, one of the most frequent questions is “What’s your favorite bird?” Sometimes I’ll give a flippant answer such as “My next life bird.” Other times, I’ll say that I love all birds and can’t pick a favorite – that each is special in its own way. I do have an affinity for Magnificent Frigatebirds, because seeing an adult male flying fifteen feet over my head while standing on a dock on Key West was the experience that triggered my choice to actively pursue the hobby of birding. But there are in fact some birds that are definitely cooler than others, be they prettier, uglier, sweet singers, or just plain quirky. One of these is the Reddish Egret (Egretta rufecens).

Reddish Egrets, once rare in Southern California, have been moving gradually up the coast. They now inhabit estuaries from San Diego through Ventura. Recently, they are visiting Santa Barbara. At Bolsa Chica Ecological Reserve, they are breeding. Birders frequently report sightings of 2 or 3 individuals. Continue reading

Wildlife Photography is Full of Surprises

Female Flame Skimmer

Female Flame Skimmer

To paraphrase Forest Gump’s mother, wildlife photography, especially video, is like a box of chocolates – you never know what you’re going to get. Animals do things on their own volition, so it always pays to wait and watch.

After looking at shorebirds along the Los Angeles River last fall, we walked back to the car through a park along the river. It was late morning and butterflies and dragonflies were quite active. Although we are primarily birders, we are interested in all of nature. So, we stopped to see what we could find.

Dragonfly Feeding Behavior

Dragonflies have two main methods of getting food: hawking and patrolling. In hawking, the dragonfly perches on the end of a branch, stump, or rock and waits for its prey to come flying by. In patrolling, the dragonfly flies up and down an area, often a path or road, and searches out its prey. Patrolling dragonflies are notoriously difficult to photograph because they are hardly ever stationary.

The Wildlife Photography Surprise

As we walked along, I noticed a Flame Skimmer. It was sitting perched on a stick in the middle of a planted area. Fortunately, Flame Skimmers are hawking dragonflies, so I decided to digiscope some video through my Kowa TSN-884 spotting scope with my micro four thirds camera. I set up, zoomed in, and started recording, waiting for something interesting to happen. The first few times the skimmer flew off its perch, I stopped recording, but it kept returning. Interested in showing that behavior, I started a new clip and decided to let the video run until it came back. Was I ever surprised and happy.

Letting the video run really paid off. When the Flame Skimmer returned to its perch, it was chewing away on a gnat! I never expected that. What a surprise! Isn’t wildlife photography fun?

Gone Fishin

We can learn a lot by watching animals. Unlike humans, they remain focused on their task at all times. This Green Heron, gone fishin at San Joaquin Wildlife Sanctuary in Irvine, California was no exception.

Green Herons, like most members of the heron and egret family, fish and crustaceans for a living. They have to get good at it to survive. Of the family members that occur in North America, the Great Blue Heron and the Cattle Egret eat land-based critters. The Great Blue Heron will eat anything it can fit in its mouth including rodents and birds. The Cattle Egret eats mostly insects, but also frogs and worms.

Season of Shorebirds – Summer 2011

The summer of 2011 is shaping up to be a fabulous season of shorebirds in California. The season kicked off with the appearance of the Lesser Sand-Plover in Orange County, CA, a cooperative bird that stayed a total of 8 days in late June, delighting many observers.

Shorebirds to the North

Little Sting season of shorebirds

Little Stint

July has been even better with the appearance of two Little Stints, both in northern California. On the 23rd, Kimball Garrett discovered another one at Piute Ponds on the grounds of Edwards Air Force Base in norther

n LA County. On the same day, a Wilson’s Plover was found at the Carpinteria Salt Marsh Reserve in Carpinteria. Unfortunately it was in a restricted area where only a limited few could get access.

The Little Stint was too good to pass up, so a group of us got up before dawn the next day and made the trek north, arriving on the site by 7:15. The bird was re-found within minutes of our arrival and we began watching this rather reddish adult shortly after. After about an hour of digiscoping pictures and video, one of the observers got a phone call saying that Guy McCaskie had found an adult Curlew Sandpiper on the salt basin at Imperial Beach, south of San Diego. You could look at the birders around you and just see the wheels turning as they all began calculating time and distance, or perhaps gauging spousal approval. Continue reading

Unusual Vagrants in Southern California

Unusual vagrants made the first half of November, 2012 extraordinary for mega-rarity bird sightings in southern California. From the 4th-7th of November, an Ivory Gull visited Pismo Beach. Then on the 8th, a Black-tailed Gull appeared in Long Beach. On the 9th, someone found a Taiga Bean Goose at the south end of the Salton Sea. The Ivory Gull was only the second one seen in California. The Black-tailed Gull was a third state record and the Bean Goose is a first. Of these unusual vagrants, the latter two are normally found in east Asia. Are these just random occurrences or are they part of a larger pattern, perhaps resulting from climate change?

Ivory Gull

Ivory Gulls are native to the far arctic where they live on pack ice and feed mostly on the carcasses of dead mammals such as seals. As the name implies, the adults are almost pure white. The only coloration is their black legs, feet and eyes, and their bill, which is greenish with a bright yellow tip.

In the 20th Century, Ivory Gulls reached the US in the Lower 48 and southern Canada in only 20 of 100 years. Few of these years had more than one bird, and most were first winter birds. Since then, Ivory Gulls have “vagrated” to the Lower 48 and southern Canada in 8 consecutive winters, and most were adults. In fact, the Pismo Beach bird was the 8th for 2010 alone, and ALL of them were adults. The vast majority of North American records are from the northeast, but recent records from Tennessee (1997), the Alabama/Georgia border (2009) and Pismo Beach are unusually far south. The Pismo Beach record is the earliest fall/winter sighting ever – typically, sightings occur between December and March with the bulk of those in January and February. See “Patterns from E-Bird” at eBird.org for more complete sighting details.

Ivory Gull

Ivory Gull

Ivory Gulls normally stay close to the Arctic Circle and are quite comfortable in that harsh environment. They have long claws, adapted for traction on the ice, but the claws are of little use on a beach where people wade barefoot in the ocean. The availability of multiple seal carcasses along the beach certainly helped keep this Ivory Gull fed. While we were there, it spent most of its time feeding.

Vagrancy among juveniles can be attributed to a successful breeding season, but among adults, it is more difficult to explain. Perhaps because Ivory Gulls rarely see humans, they are often relatively tame. At Pismo Beach, birders frequently surrounded the gull. Joggers and dog walkers passed by, but the gull seldom flew in response to close approach. The dramatic changes in vagrancy patterns may be cause for concern about this already endangered population of Ivory Gull. Seeing one this far from the pack ice was incongruous, but delightful.

Black-tailed Gull

"<yoastmarkBlack-tailed Gulls are native to eastern Asia but are casual visitors to coastal Alaska and northeastern North America. They are accidental in California. Neither of the two previous records were chase-able. The first bird visited San Diego Bay in 1954. It was collected. A visiting birder photographed the second one at a public beach in Half Moon Bay (12/29/2008). Many birders searched, but never refound the gull.

Black-tailed Gulls are larger than Ring-billed Gulls and smaller than California Gulls. Adults have a bright yellow bill with a red spot followed by an uneven black ring and a bright red tip. The face shows bright white eye crescents above and below the yellow eyes with their red orbital ring. They also have yellow legs and feet. Despite the name, the tail is not completely black, featuring a broad black sub-terminal band between a white rump and narrow white terminal band. The mantle is slate gray, and their wing tips have much smaller white mirrors than other medium to large white-headed gulls.

The Long Beach Black-tailed Gull remained through at least the afternoon of the 10th. It stayed in its general location all day, moving only between the beach, the water, and some buoys. The bird was absent when we arrived pre-dawn on the 9th and only a few gulls were on the beach, but it flew in at 6:15 AM to the delight of about 30 birders, some of whom came from as far away as the Sacramento area. While on the beach, the it spent much of its time preening in the midst of a flock of Ring-billed, California and a few Western Gulls.

Taiga Bean Goose

In 2007, the AOU split Bean Goose into Taiga Bean Goose and Tundra Bean Goose, based on breeding habitat: forest bogs in the subarctic taiga or on the arctic tundra. The Taiga Bean Goose has a black bill with a yellow-orange tip. It lacks the white at the base of the bill of the Greater White-fronted Goose (which has an orange bill).  A longer bill, and narrower at the base, distinguishes it from Tundra Bean Goose. Bean Geese have a habit of grazing in winter bean field stubble, hence the name. Bean Geese are native to Eurasia, and the Taiga is the largest species.

This individual showed up at the south end of the Salton Sea at Unit 1 of the Sonny Bono Salton Sea National Wildlife Refuge on Vendel Rd. This Taiga Bean Goose is of the Middendorf race from eastern Siberia, which may merit separate species status itself. There are only about 5000 Middendorf’s Taiga Bean Geese. This goose associates with a huge flock of mostly Snow and Ross’s Geese that also includes three Greater White-fronted Geese. Other North American Bean Goose records were mostly from coastal Alaska, along the Aleutians or in the northeast (US and southeast Canada). There are also two 2003 records from the state of Washington.

Why the Vagrancy?

The question many California birders ask is: why are we seeing these mega-rarities all in southern California in early November? Could these occurrences be due to climate change? Some evidence may support that conclusion in the case of the Ivory Gull. However, there is as yet no causal connection between climate change and the vagrancy of the other two birds. Regardless of the reasons, it sure is an exciting time to be birding in southern California!

Digiscoped Video – American Oystercatcher

On Saturday, May 22, 2010, I followed up on a report of an American Oystercatcher at a few locations in Laguna Beach. I tried Crescent Bay first, and was fortunate to find five Oystercatchers on the rocks below the point. There were three Black Oystercatchers, while the other two looked pretty good for Americans.

What are they?

Black and American Oystercatchers interbreed and their hybrid offspring can be anywhere on a cline from pure Black to pure American. We had to evaluate these birds for purity. J. R. Jehl, Jr. developed a rating system used by ornithologists to determine where on the cline a given bird falls. Because there are several genetic variations that are involved, we use ten different characteristics to judge the birds. Nine of them have a score between 0 and 4. The belly coloration goes from 0 to 6. A bird with a score of 0 to 9 rates is a pure Black Oystercatcher. One scored from 30 to 38 is pure American, and everything in between is a hybrid.

I took this video with a Nikon CoolPix P6000 attached to a Kowa TSN-884 spotting scope at a distance of 96 yards measured by a Zeiss Victory PRF laser rangefinder.

Is Either an American Oystercatcher?

The Oystercatcher in the center of this video has white upper tail coverts (Jehl’s score 4), basal half of all retrices were white (4), chest sharply delimited black to white on upper chest (4), belly entirely white (6), undertail coverts entirely white (4), thighs entirely white (4), greater secondary coverts 6-15mm (3), white present on some of inner primaries (3), underwing coverts entirely white (4), axillaries entirely white (4). The Jehl’s score for this American Oystercatcher is 36 out of 38.

The hybrid Oystercatcher, seen on the left as the video starts, has upper tail coverts black (Jehl’s score 0), retrices mainly black with some white in the vanes (1), black chest bordered by jagged edge on upper chest (3), belly entirely white (6), undertail coverts mainly white (3), thighs entirely white (4), greater secondary coverts 6-15mm (3), white present on secondaries but not primaries (2), underwing coverts mainly white (3), axillaries entirely white (4). Jehl’s score is 28 out of 38, so close, but not close enough.
