On a recent birding trip to southeastern Arizona, I ran across a mammal I have long wanted to meet: the White-nosed Coatimundi, Nasua narica. Known as a coati for short, this attractive beast is a member of the raccoon family, Procyonidae, as suggested by its facial mask and faintly ringed tail. All of the world’s four coati species reside only in the Americas. Other species include the Eastern and Western Mountain Coatis, and the South American Coati. Only the White-nosed Coati occurs in the United States, where it is found from southern Arizona, across the southwest corner of New Mexico to south Texas from El Paso to the Gulf of Mexico. The White-nosed Coati’s range extends all the way through Central America into northwestern Columbia. Continue reading
While every corner of the globe brings its own plethora of bird species to the table, few countries attract such attention as Peru. Second only to Columbia in the sheer number of species, Peru’s vast array of climates house species from all areas of the birding spectrum. Perhaps the most intriguing species in the nation is the Andean Condor.
Heavier than all other flying birds and second only in wingspan to the Wandering Albatross, this giant scavenger has always struck awe in the entire birding community. I am certainly no exception, and I finally got to see some myself in August of 2018. Continue reading
When word broke on a Monday of a Red-flanked Bluetail found at the William Andrews Clark Library, it caused a panic. We scrambled for our field guides to see what one even looked like, and then looked up the library hours of operation. The news wasn’t good: the facility only opened during the week when most of us are working instead of birding. This whole working-for-a-living thing really puts a damper on birding! We spent an anguished week watching the reports verifying the bird was still present. Fortunately, the bird hung around, so we drove to Los Angeles to chase it. A crowd of about 100 local birders milled around by the library gate, mixing with visitors from further afield. Promptly at 9:00 am, the gates opened and people started speed-walking towards the opposite end of the property. The grounds were beautiful: lush, with mature lawns, dense hedges, and concrete walkways shaded by huge ficus and magnolia trees. Continue reading
Recently, a report of a Wood Sandpiper (Tringa glareola) up in southern Humboldt County, California, sent our pulse jumping. The Wood Sandpiper is a Eurasian shorebird, related to our Solitary Sandpiper. There are comparatively few records of this bird for North America. Wood Sandpipers stray as far as New York occasionally, though most records come from Alaska. This bird is rare enough that some North American field guides don’t even illustrate it. When the photos came through, confirming the bird, we put together a whirlwind trip to go see it. It was a 12-hour drive to the Russ Ranch Wetlands where the bird was, so we set off the night before and drove through the night to reach the marsh the next morning. Continue reading
Goodbye Eagle Optics Rangers. Hello Barska Level ED
One of the most popular low-cost binocular series in the history of Optics4Birding has been the Eagle Optics Rangers. The Ranger went through several incarnations and improved each time. So, when Eagle Optics closed, we were disappointed to lose the Rangers, and we started looking for a good replacement. In January 2018, we found the Barska Level ED Open Bridge binoculars. Even without a head-to-head comparison, we knew had found our replacement. So, we arranged an evaluation piece from Barska to try them out. Read on to find out why we feel so strongly about the Barska Level ED binoculars. Continue reading
Few subjects provoke the ire in a roomful of birders more rapidly than whether or not to count introduced species. The ins and outs of what is “countable”, what is “established”, and what is still an exotic alien has reddened faces and clenched fists among birders for decades. After that comes the discussion of which state bird records committee is loosest or tightest in their approach to exotics. By then, former friends begin to disperse faster than the young of the year.
But in the end, that is not really what matters here. When it comes to counting exotics, I find myself more and more adopting an eBird stance. That is: count them all, do it as accurately as possible, and submit your data. In the end, the importance of this goes far beyond a mere life list. What matters most is the impact that these growing populations of exotics have upon our native species and the environment in general. Make no mistake about it, that impact is huge. Continue reading
Any discussion of introduced bird species in North America would be incomplete without considering exotic parrots. In fact, parrots and their allies constitute the single largest class of exotic birds on the continent. According to Forshaw’s Parrots of the World, there are/were 356 parrot species extant in the world as of 2010. Over 20 psittacids (parrots and their relatives) occur frequently enough in North America that the major field guides illustrate them. Yet only eight species grace the official North American checklist. Of these, arguably only six became established anywhere. Those six are: Monk Parakeet, Nanday Parakeet, Green Parakeet, White-winged Parakeet, Red-crowned Amazon and Rosy-faced Lovebird. See the table of species and their status below.
The irony of it abounds. Historically, North America only ever boasted two native psittacid species: Carolina Parakeet and Thick-billed Parrot. The Carolina Parakeet is famously extinct. Thick-billed Parrot was extirpated from its tiny historical range in the United States decades ago. Moreover, they are endangered in their restricted Mexican range. All efforts to re-introduce Thick-billed Parrots in the southwest met with failure. So any parrot seen in North America is by definition, an exotic. Perhaps many species not on the official checklist are well on the way to becoming established. Continue reading
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
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
