NASA Captures “EPIC” Earth Image (click on photos to enlarge)
Has mankind really driven the planet to the edge of a catastrophic crash of life? Is greed blinding us to what is right in front of our faces? Some would say maybe these claims are a little too reactionary. Okay, so a bit of Florida gets wet, and maybe some people will have to move inland. Can’t science just come up with new technologies to solve the dilemmas we face? Does industry just need to develop a practical and economical electric car? What would happen if we just did “business as usual”? The claims of doom are a bit extreme and, if we accept them at face value, they are really inconvenient to living our lives. What is science telling us about what is happening right now, what we face in the very near future, and what can be done to avoid it?
Earth really is exceptional. From our naturalist point of view, this planet’s life is unimaginably beautiful and breath-takingly diverse. But it doesn’t take a genius to see that Earth’s abundance and diversity is disappearing. There is a point at which this decline becomes mass extinction, and that point is much closer than you may think. Our own survival is indeed inextricably tied to the health of our world. If we expect science to save us, then we need to listen to what science is telling us. Continue reading →
Today the buzz is the solar eclipse. Although here in Southern California we did not get the full solar eclipse, it was still a pleasure to see the partial occlusion. Of course, having a store full of spotting scopes and a solar filter for a spotting scope we snuck out briefly from our work to take a couple quick photos at the peak of the event, out in the parking lot.
The Optics4Birding store is located about 45 miles south of downtown Los Angeles. The peak of the eclipse happened at about 10:20 AM. It really was quite interesting. Although without filters to look through you would never know it was happening. The sun is so bright that from our vantage point and even with about 60% of the sun being eclipsed, with the naked eye you didn’t notice any difference. Contrary to this, wearing solar filter glasses it was quite interesting. Looking at this through a spotting scope was really interesting.
On the Kowa 88mm TSN 884 we used a Panasonic Lumix G-6 Micro 4/3 camera with an Olympus 14-42 zoom lens. We attached this using the Kowa TSN-DA10 digiscoping adapter. Both setups are very simple to take pictures with. Normally we would be taking nature photos. Of course, this was a natural event! Typically, though, most of us are photographing birds or animals with our spotting scopes.
It did make for a fun morning and a nice break from work. The weather cooperated and we had nice clear skies. Certainly, many people will have gone out to see this today. Having the right stuff to enjoy these type of events is always a pleasure.
The amazing story of Eureka, the Western Snowy Plover, began with an unexpected event on Memorial Day weekend of 2017. I do quarterly surveys for Western Snowy Plover (Charadrius nivosus nivosus), an endangered species along the west coast of North America. We survey a 2.2-mile stretch of Huntington State Beach in Orange County, CA. With my teammates, Doug and Chuck, we’ve surveyed this beach every January, March, May and September for four years. Huntington State Beach is a crucial roosting and feeding area for Western Snowy Plover, and we see some on every January, March or September survey.
Surveying takes three of us because the beach is quite deep at about 500 feet from the parking lot to the water’s edge. Our team walks in parallel, zig-zagging down the beach to cover everything. Snowy Plovers, with their pale, wet-sand plumage, can be hard to spot. They make it harder by crouching down in little divots on the beach, hiding until danger is right on top of them. May is the boring survey because it’s the only time we don?t see the plovers on our beach. By May, the plovers have migrated to their breeding areas elsewhere. Continue reading →
Just when you think you understand things a little, along comes an event that puts you in your place! The rainfall here on the west coast of the United States in 2017 has been a bit odd. Very welcome, to be sure, but a bit odd. We greatly exceeded expected rainfall this winter and spring. From Washington down to northern California, experts declared an official end to a drought that lasted about a decade. This refilled reservoirs and lakes in that region to capacity.
In southern California, the rain didn’t erase that long drought as completely, but it still had staggering effects locally. One factor that makes the rain so odd is that it occurred completely outside the Pacific oscillation cycle. The El Nino and La Nina events govern these oscillations. These rains at Anza-Borrego State Park produced a huge wildflower super-bloom. That greatly benefited White-lined Sphinx moths and their predators. Continue reading →
The highly sought after Unspotted Saw-whet Owl inhabits the cloud forest mostly above 8,000 feet in elevation. In this photo, light dew is visible on the owls head from the mist in the forest. In this photo, light dew is visible on the owls head from the mist in the forest.
After 15 years, I finally got brave enough to go back in search of the Chiapas owls. Chiapas is the southernmost state of Mexico that borders Guatemala. This was pretty much a mandatory destination to complete our sister owling.com website. There is no other state in Mexico with as many owl species as Chiapas. This area is also crucial to our current understanding of owl taxonomy. New divisions and more accurate classification of the owls are slowly becoming known and being clarified by science.
Chiapas is spectacular for wildlife and has an extraordinary history, but suffers from terrible pollution and horrific habitat destruction. While the natural wealth is immense, the population is poor, and traveling there can be dangerous. Having done this before, my plan was to mitigate risk, so I invited a friend and hired a guide. We documented nine species of owls in nine nights (video, recording, photograph, etc.) along with over a hundred eighty species of birds and mammals in the daytime. I will cover more of this in an upcoming article. Continue reading →
The Sea and Sage Audubon chapter winter pelagic trip ran recently on a February day following strong winds and storms from the southwest. A fairly large swell kept people on their toes for most of the day (going airborne while on a boat is bad!!). It was by turns rainy, windy, drizzly and sunny. For those who braved the weather, however, the returns from this trip were spectacular! Every pelagic trip begins with a sense of hope: maybe you’ll see something rare, like an albatross. But realistically, you never really expect one to show up. As it turned out, they weren’t long in coming, and in this case it was an unprecedented one.
A Laysan Albatross soars past the boat at close quarters.
The boat left Dana Point harbor and headed straight out into the California Channel. Four miles out, a call of “Albatross!” went up from the back of the boat. The usual stampede ensued! The bird in question, a spectacular adult Laysan Albatross, Phoebastria immutabilis, provided a first record for Orange County. This particular individual was a handsome adult bird. The distinctive dark wings and all-white body, nape and crown are distinctive. And the grayish shadow to the auricular and large pinkish bill with a pale bluish tip seal the deal. The bird made several passes by the boat, found nothing that interested it, and sailed off, leaving us all wishing for more. Alas, it was not to be as we never saw this bird again during the entire trip. But it sure woke everyone up! Continue reading →
The brackish and salt marshes of California are an important and globally-threatened ecosystem. At this point, a century of “civilization” has filled, polluted or destroyed over 95% of California’s coastal salt marshes. These estuaries and marshes are incredibly important. Biologically speaking, they are some of the most productive acres of habitat anywhere. They host tremendous species diversity, and act as vital nursery grounds for many ocean species. They serve as feeding and breeding resources for a variety of species. Endangered species like the California Least Tern, Western Snowy Plover and Light-footed Ridgway’s Rail all use coastal saltmarshes. They also provide wintering or year-round habitat for a number of interesting bird species. The focus of this article is three such species: Belding’s (Savannah) Sparrow, Large-billed Savannah Sparrow and Nelson’s Sparrows. Continue reading →
This Black-capped Chickadee was a regular visitor to the yard of the guest house where we were staying.
Seven chickadee species regularly occur in North America: Carolina, Black-capped, Boreal, Mountain, Chestnut-backed, Mexican and Gray-headed Chickadee. Chickadees form a closely-related group, all belonging to the same genus (Poecile). Chickadees are members of the family Paridae, which also includes the titmice. European birders call chickadees “tits”, and tits include some of the largest and most colorful members of the family.
Chickadees are small birds with big personalities. Chickadees get their name from their songs, which sound as though they are saying “chick-a-dee-dee-dee”, or variations on that theme. They are small birds (the largest are just 5.5 inches long) with proportionately large, round heads, variable amounts of white in prominent cheek patches, and always a black throat. All of our chickadees have short, sharp bills well-adapted for hammering open seeds or grabbing bugs out of crevices. Chickadees are gregarious, flocking birds except when nesting and fledging young each year. Then the flocks break apart and birds set up breeding territories. Chickadees frequently visit bird feeders across the continent, making them some of North America’s best known and most beloved birds. Continue reading →
A sub-adult Black Skimmer close-up over a pond at San Joaquin Wildlife Sanctuary in Irvine, California
The Black Skimmer (Rynchops niger) is a wonderful weird bird that breeds across the southern half of North America. Black Skimmers live and forage almost exclusively at coastal locations or within about 20 miles of the shore. They are primarily year-round residents here, though some winter as far south as the Yucatan. A large population of Black Skimmers resides year-round in a range roughly corresponding to the entire Amazon drainage basin.
Black Skimmers are easily recognizable by their bizarre asymmetric bill, longer below than above. Black Skimmers have clean white underparts, throat, neck collar (non-breeding only) and around the bill. Their feet and the inner bills are bright orange; the tips of both mandibles are black. Juvenile Black Skimmers are more brownish-gray on the upper surface, and have relatively dull orange feet and inner bill parts. At birth, juvenile skimmers mandibles are of equal length. But by the time they fledge four weeks later, the lower mandible is a centimeter longer than the upper one. Continue reading →
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.
