Category Archives: Spotting Scopes

Spotting scopes are terrestrial telescopes that pick up where binoculars leave off. They have much larger magnifications and are usually mounted on a tripod or other support device. In these configurations, potting scopes make it easier to share a view with others without having to give complicated directions about where to look.

Kowa TSN-EX16 Extender Review

Kowa TSN-EX16 Extender

Kowa TSN-EX16 1.6x extender.

Kowa America recently released the TSN-EX16 Extender. The extender is placed between the body of a Kowa TSN-880 or TSN-770 spotting scope and the eyepiece and multiplies the standard magnification by 1.6x. This is analogous to photographic lens extenders that mount between a camera’s lens and body. With the current 25-60x zoom eyepiece (Kowa TE-11WZ) that fits these spotting scopes, the resultant magnification becomes 40-96x!

But what about the historical downsides of extenders? How does the optical quality hold up? Is there much loss of light? What about sharpness and clarity? I took out my trusty TSN-884 and Panasonic Lumix G6 to find out. An accommodating Peregrine Falcon stayed long enough for me to get some test shots. Continue reading →

American White Pelicans Feeding Behavior

American White Pelicans preening

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.

Vermilion Flycatcher

Male Vermilion Flycatcher, Mazatlan, Mexico

The Vermilion Flycatcher (Pyrocephalus rubinus) is a small tyrant flycatcher in the family, Tyrannidae. Vermilion Flycatchers live in the New World, ranging from central Argentina and covering much of South and Central America. Ornithologists recognize at least 12 sub-species of Vermilion Flycatcher. Some experts think the Galapagos Island Vermilion Flycatchers may be a full species on its own.

In the United States, we find Vermilion Flycatchers mostly in the desert southwest, where their range extends to southern Nevada. Their California range includes much of the Mojave Desert, in San Bernardino County. Additionally, it extends across most of Riverside and Imperial Counties and into Los Angeles, Orange and San Diego counties. In coastal California, we see Vermilion Flycatchers increasingly often though more likely as winter visitors. However, their range is expanding and there are indications that their breeding range is expanding towards the coast. Here in Orange County, Vermilion Flycatchers often use edge habitat like golf courses and athletic fields. Continue reading →

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

Olive-backed Pipit, Yorba Regional Park, 01-NOV-14

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 →

Rufous-backed Robin

The Rufous-backed Robin at 29 Palms Inn

Last weekend, we drove out to Twentynine Palms, CA to look for a Rufous-backed Robin previously reported there. The bird had been present for at least a week on the lush grounds of the 29 Palms Inn resort. This resort is a 70-acre oasis of greenery and water for wildlife in the middle of the Mojave Desert, and the owners and operators of the inn are very birder friendly. Thus, it consistently draws in wildlife of all kinds from the surrounding desert. The 29 Palms Inn sits close to Joshua Tree National Park, in extreme south central San Bernardino County, CA.

Lincoln’s Sparrow

Lincoln’s Sparrow in shadows

The Lincoln’s Sparrow (Melospiza lincolnii) is a smallish member of the same genus as the familiar Song Sparrow (Melospiza melodia). Lincoln’s Sparrows have nearly as broad a distribution as Song Sparrows. Lincoln’s Sparrows only appear in southeastern states like Virginia, the Carolinas, Georgia and Florida during migration. They are migratory, breeding in far northern Canada and at upper elevations of the Rocky and Sierra Nevada ranges. Thus, Lincoln’s Sparrows abandon much of their listed range except as passage migrants.

Here in southern California, we see these beautiful little sparrows primarily in winter. Lincoln’s Sparrows do breed as nearby as the San Gabriel and San Bernardino Mountains. The winter range of Lincoln’s Sparrow stretches almost all the way south to Panama. Sometimes you can find upwards of 20-30 Lincoln’s Sparrows in a large, loose winter flock.

Red-throated Pipits Return to SoCal

Red-throated Pipit

Migration of Red-throated Pipits

One of the most amazing migratory flights is that of the Red-throated Pipit Anthus cervinus. This pipit breeds primarily in eastern Europe and Asia, almost completely above the Arctic Circle, and on the Kamchatka Peninsula. There are also some breeding grounds in Alaska’s northwest coast, Bering Sea islands, and possibly also in the Yukon.

Most Red-throated Pipits migrate down the western Pacific and winter in China and as far south as Australia. Some of the more eastern breeders take a more easterly route. These 6-inch passerines fatten up on the islands in the Bering Sea and then head off on a 3,000 mile flight across the Pacific Ocean to the California coast. While annual each October in southern California in small numbers, mostly on sod farms, Red-throated Pipits are almost unheard of much north of the San Francisco Bay Area. This tells us that they rarely follow land and fly straight across the ocean. The Red-throated Pipits that migrate through SoCal winter in Baja California. eBird records show them wintering near La Paz, Baja California Sur, Mexico. Continue reading →

Variegated Meadowhawks

The Variegated Meadowhawk (Sympetrum corruptum) is a large North American dragonfly. Typically, Variegated Meadowhawks range across Canada from British Columbia to Ontario, and most of the U.S. from California to Florida. Averaging 1.5 – 2 inches in length with a wingspan of 2.5 – 3 inches, scientists classify Variegated Meadowhawks as medium-sized dragonflies. These highly migratory dragonflies sometimes turn up on Caribbean Islands and even in eastern Asia. Typically, they often cruise over dry land as often as in the vicinity of ponds and streams. Variegated Meadowhawks are “sally hunters”. That means they launch on feeding sorties, and return to the same spot, much like a Western Wood-Pewee. Thus, sally-hunting makes these dragonflies much easier to photograph than many subjects. And well worth it. Continue reading →

Wandering Skippers

Wandering Skipper nectaring on Heliotrope Flowers

The Wandering Skipper (Panoquina errans) is a small butterfly that lives only in coastal saltmarsh. They range from Santa Barbara County, California south to northern coastal Baja and the Sea of Cortez. Their range is a narrow band close to the ocean. This is because this butterfly’s larval food plant, saltgrass, only lives in coastal salt marsh. Wandering Skippers fly in late summer and fall, usually in two broods.

Finding Wandering Skipper

As it happens, one of the largest Wandering Skipper colonies is right here in Orange County at Upper Newport Bay. References said that they were present in the highest density in the vicinity of Big Canyon. So we started to look for them in late July. They weren’t easy to find! It wasn’t until August that we found a single individual, nectaring on the tiny purple flowers of European Seaheath (Frankenia pulverulenta). We went back several weeks later and found a fair few more of them, again feeding on the Seaheath. Continue reading →

Dance of the Reddish Egret

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 →
