The Undiscovered Country

2021 Merced County Species-to-Date (as of last checklist)
Life List = 186
Year List = 140

Whereas this title may bring to mind either Shakespeare’s Hamlet or Gene Roddenberry’s Start Trek VI, it is merely a reference to the Eastern Merced County grasslands that I had never ventured into before.

I again scoured eBird for recent reports for Eastern Merced County. I seem to be following in the footsteps of Dale Swanberg as he recently reported a couple of my target birds for this area, this time of year. Most of his reports were for areas that I had not seen before.

TARGET BIRDS FOR THE DAY

The following photos were all taken in Stanislaus County, but are the focus of my adventures today.

Ferruginous Hawk
Rough-legged Hawk
Golden Eagle
Lewis’s Woodpecker
Prairie Falcon
Vesper Sparrow

White Rock Rd. STOP #1

I started driving north and then east on White Rock Road enjoying almost zero traffic for the entire area. Almost immediately I spotted two adult Bald Eagles roosting in a tree.

A short distance later I spied another very distant adult Bald Eagle, and then an even more distant immature Bald Eagle. I reached the county line and turned back, inching along, looking at every sparrow in hopes of finding a Vesper. A very white hawk standing in the field caught my attention. I approached it carefully and noted that it was one of my target birds for the day, a Ferruginous Hawk. Unfortunately as luck would have it, a large cattle truck rumbled very noisily by scaring off my Kodak Moment. 😦

A consolation Burrowing Owl was hiding in the gravel and rock pilings. A barely recognizable photo shows the ID, but it’s not the kind of photo I would like.

ONWARD TO STOP #2

Next up was E. South Bear Creek Dr. in hopes of re-finding the Vesper Sparrow reported by Dale Swanberg. There was literally no traffic and tons of sparrows to sort through. At the end of the road along the fence line was another Ferruginous Hawk, just a bit too far away for a good photo.

Once again, the Vesper Sparrow must not have returned from vespers last night because I didn’t find one here today.

CONTINUING TO STOP #3 – Lake Yosemite County Park

Here I was hoping to find and photograph one of the continuing Vermilion Flycatchers, Mountain Bluebirds, or the Thayer’s Gull photographed by D Krajnovich. It was a sunny, cool and breezy spot, but unfortunately the only thing I succesfully photographed was a pair of Canada Geese at the entrance.

Canada Geese

There was also a nice osprey soaring overhead, but it never got close enough for a good shot.

Same thing for a distant Belted Kingfisher’

Belted Kingfisher

On the way out, I spotted a likely candidate for the female Vermilion Flycatcher so I turned around for a second pass. Unfortunately there was a lot of traffic and all I could do was slow down and shoot while driving past it. I then made the mistake of assuming it was my hoped for bird and I added “it” to my eBird checklist and closed it out. It wasn’t until I got home and had the chance to look at my images that it was painfully clear that my Vermilion Flycatcher was just a Say’s Phoebe. Oops!

Birding Between the Storms

2021 Merced County Species-to-Date (as of last checklist)
Life List = 183
Year List = 122

Seeing a break between storms, I reached out to Rich Brown and Dale Swanberg to see if they wanted to explore the San Luis Reservoir State Recreation areas. I was hoping that something unusual would show up with the unsettled weather and strong winds the day before. We met up in Santa Nella and Dale lead us to Los Banos Creek Reservoir which is a part of the recreation area that I had never visited before. I noticed a couple of new year birds that went unrecorded for the time being as I’m sure I will get them at an actual birding hotspot later (Great-tailed Grackle and Yellow-billed Magpie).

25 Jan 2021 – FIRST STOP LOS BANOS CREEK RESERVOIR

At the bridge over the Delta Mendota Canal, both Rich and I stopped to quickly photograph a female Canvasback that was swimming away.

Canvasback (female)

We quickly caught up with Dale, who was wondering what we were doing. The entrance seemed to be lacking the usual entrance sign that most state recreation areas have. There was a sign at the base of the dam though.

Los Banos Creek Reservoir Dam

After getting our parking spot assignment, we parked near the entrance, searching for roadrunners that might be hanging out. We dipped on the beep-beep, but had an encounter with a very large pig and about 20 little porkers running behind her. The skies portended inclement weather and the water was choppy.

Los Banos Creek Reservoir

I was amazed at the number of Aechmophorus grebes hanging out around all coves and inlets of the reservoir. Aechmophorus refers to the genus name of Western and Clark’s Grebes that used to be conspecific until their split back in the late 80s. A quick count using my telescope of the birds I could see gave me a total of a little over 300 birds with the ratio of Western to Clarks at about 10:1.

Aechmorporus Grebes

For a comparison, Clark’s Grebes have an orangish-yellow tint to their bills and their eyes are entirely or mostly surrounded by white facial feathers.

The Western Grebe lacks the orangish tone in the yellow bill and their eyes are surrounded by black facial feathers.

On the way out as we were fording the creek, off to our left was the big momma pig hiding quite effectively in the reeds.

SECOND STOP MEDEIROS AREA

The winds had picked up as we reached the boat launch area and the birds were scattered quite a ways from where we were. Dale and Rich (socially distanced of course), searched every corner for something unusual or new for the year.

Dale Swanberg & Rich Brown

As we skimmed over the rafts of Ruddy Ducks and American Coots, we could see distant Canvasbacks, Buffleheads and Common Goldeneyes with nary a Barrow’s to be seen.

Up ahead something caught my eye. It was a small grebe, much smaller than either a Western or Clark’s and it had too distinctive of a white cheek patch to be an Eared Grebe. We pulled over, jumped out and got our binoculars on a nice Horned Grebe. This would be the first of this species to be recorded in the county this year. Horned Grebes are more of a coastal wetlands and bay bird with a few spotted in the valley each year. Not rare, but certainly uncommon.

Horned Grebe
Eared Grebe for Comparison

After checking off the Horned grebe on our eBird Mobile checklist, we focused on the many Scaup flocks, hoping to ID a Greater in with the Lessers. Greater Scaup are similar to Horned Grebes in that they are more usually found along the coast. The one spot they seem easier to find though is exactly where we were.

Greater Scaup

The Greater Scaup is slightly larger, has a rounded head without any peak and a bill tooth that is relatively wide at the distal end of the bill.

Greater Scaup

We decided to give the other side of the reservoir a check to see if the winds were a little less knock your hat off.

https://ebird.org/checklist/S79887168

THIRD STOP SAN LUIS CREEK AREA

We were treated to much calmer conditions at the San Luis Creek area and were treated to a flock of Lark Sparrows as soon as we started down the trail.

Lark Sparrow

We enjoyed lots of Juncos and sparrows and some offshore Bufflehead as we walked along the shoreline. There were plenty of kinglets, sparrows and Bushtits, but nothing else unusual or new for the year.

On the way out a nice Common Raven posed for me.

Life List = 179
Year List = 99

HENDERSON PARK

Nestled next to the Merced River, surrounded by riparian trees and home to a myriad of ornamental evergreen and deciduous trees in an open setting, Henderson Park was our target for the morning.

COLLEGE CREDIT FOR BIRD WATCHING – WHAT?

Almost 36 years ago I first visited the Snelling area, (Henderson Park specifically), on a college field trip. I, along with 20 other college students, were getting credit for the requisite “Winter Term Course” for graduation and I was ecstatic that Winter Birding was an option. As a matter of random circumstance, I had to take Ornithology the previous spring as it was the only upper division science course I could fit into my fulltime working, two kid family, busy life. As a result of taking Zoology 4630 – Ornithology, I had become hooked on birding and it seemed surreal to get credit for going birding. The one thing I remember about that particular trip was seeing three species of goldfinch. I only recorded an X for the 32 species seen, so my eBird list doesn’t have numbers.

eBird Checklist Link for 2/19/1985

ABOUT HENDERSON PARK

Designed by county surveyor and architect William “Bill” E. Bedesen, Henderson Park is similar to Lake Yosemite which Bedesen also designed for the WPA. Henderson Park has a sister WPA-constructed park near Hillmar, called Hagaman Park. Both have cobble stone-faced entrances. WPA work at Henderson Park includes a clubhouse, comfort station and utility shed, as well as curved stone walls. All are built of concrete blocks with a cobblestone veneer of stones that were dredged from the Merced River. https://livingnewdeal.org/projects/henderson-park-snelling-ca-snelling-ca/

FOLLOWING FOOTSTEPS

Recent eBird reports by Dale Swanberg, Richard Brown, Sam Fellows and Gary Woods helped me set a target list, both for new species for my year list and for photos, always more photos! High on my lists were: Red-breasted Sapsucker, Chipping Sparrows, White-throated Sparrow, Golden-crowned Kinglets, Red-breasted Nuthatch, Brown Creeper, Pine Siskin and the unusual Slate-colored Junco, a sub-species of Dark-eyed Junco.

Stalking my Prey – As can be seen in my eBird Mobile Tracks map above, I wandered around and around, going wherever I saw or heard birds.

THE ONE THAT GOT AWAY – ALMOST

After 2 1/2 hours of searching unsuccessfully for my last target bird, White-throated Sparrow, I headed home. I was determined to go back better prepared and with an expert! Two days later, Richard Brown accompanied me back to the park and he showed me the exact brush pile that he had photographed the sparrow on 4 days before.

After a short distraction by a Phainopepla…

we crept carefully to the perfect position with the sun to our backs, moving ever so slowly and BAM! It popped up.

COVID-19 Birding – A Therapeutic Walk in Nature

Contact with nature benefits our mood, our psychological well-being, our mental health, and our cognitive functioning. For centuries outdoor enthusiasts have given testimony to the joy one can derive from a simple walk in nature.

“One touch of nature makes the whole world kin.”

― William Shakespeare
Isaac Gain

“Look deep into nature, and then you will understand everything better.”

― Albert Einstein
John Harris

“In all things of nature there is something of the marvelous.”

― Aristotle

BENEFITS OF BIRD WATCHING

Stress reduction

study from the University of Exeter in England found that people living in neighborhoods with more birds and tree cover are less likely to have depression, anxiety and stress.

The study, published in the journal BioScience, surveyed more than 270 people from towns throughout southern England. Researchers found a positive association between the number of birds and trees in a neighborhood and residents’ mental health, even after controlling for a neighborhood’s poverty level and other demographic factors.

Richard Taylor

“Evidence is there to support the conclusion that contact with nature benefits our mood, our psychological well-being, our mental health, and our cognitive functioning,”

Jonathon Gain

Improve cardiovascular health

Many may be shocked to learn that birding can count as a workout. But often, locations that offer the best opportunities for bird watching are located off of the beaten path and require a bit of a hike in order to reach. Getting your blood pumping with a moderately-paced walk is a great way to keep your heart healthy, and by taking part in an activity you enjoy, you won’t even notice you’re getting in a workout.

Harold Reeve

Hone patience skills

The payoff of bird watching isn’t always immediate, and usually requires time spent waiting for the much anticipated glimpse of the birds you’re seeking. Refining your patience skills isn’t only a practice that will improve your mental well-being, but also has physical health benefits. A 2007 study found that people that are more patient are less likely to experience headaches, ulcers, pneumonia, acne and other health problems.

Luis Gain

Obtain quicker reflexes

After a lengthy wait, a bird watcher has to be ready at any given second to grab their binoculars or camera to bask in and capture that long-awaited moment. Every birding opportunity gives you the chance to exercise your reflex speed, as well as improve upon it. Having fast reflexes not only allows you to be a successful bird watcher, but will prevent a barrage of small disasters from happening in your day-to-day life and help you better thwart off danger.

Eric Caine

SUGGESTIONS FOR PANDEMIC-SAFE BIRDING

With just a few social-distancing tweaks added to your routine, birding (ornithology sessions) can be safely practiced in most outdoor settings.

  • Don’t go with a group of your friends
  • Avoid public transportation
  • Keep at least 12 feet away from others not in your immediate family social bubble.
  • Have a mask at the ready in case others approach within the 12 foot limit.
  • Don’t share optics with others not in your immediate family social bubble
  • Have a bottle of disinfectant in your car and use it liberally as soon as you return to it.

ORNITHERAPYTAKING BIRDING TO ANOTHER LEVEL

WHAT IS ORNITHERAPY?

Ornitherapy is a portmanteau of the terms ornithology (the study of birds) and therapy. Borrowing from “Our Guide to Ornitherapy – Getting Started” by Whitehawk Birding, “Simply put, Ornitherapy is the practice of observing birds to calm the mind, to ground or center yourself, or to help focus your thoughts on the present moment. 

Harold Reeve

Ornitherapy endeavors to transform the data-intensive, species listing science that is birding, into a sensory journey of the sights, sounds, smells and species interactions of nature. Ornitherapy is more about the sensory experience as one becomes enveloped by the sphere of life.

“The question is not what you look at,
but what you see.”

― Henry David Thoreau

Connecting to the natural world facilitates streams of creativity and learning, while providing benefits such as: stress reduction, improved focus, and a more positive mindset.

San Luis NWR–West Bear Creek Unit

As Benji and I approached the West Bear Creek Unit of the San Luis NWR, I knew it was going to be a challenge. Visibility was no more than 100 yards at best. The area had lots of water and the conditions seemed pretty good to attract wintering waterbirds.

While there were many White-crowned Sparrows feeding along the tour route and a good number of Marsh Wrens were vociferously stating their presence, there was almost no sign of waterfowl.

“I don’t know dad, I can’t see anything in this fog…”.

We left after 40 minutes with only 25 bird species observed. (On a side note, there were lots of Squirtles and Mudkips here – gotta catch them all.) Next Stop Santa Fe Grade!

eBird Checklist Link

Santa Fe Grade–Patman Grade Rd. to Hwy 165 (south end)

Santa Fe Grade is a 13 mile, mostly dirt road that runs from Hwy 165 up to Hwy 140. It is surrounded by rangelands and lots of hunting club marshes. Due to the length, eBird has a north and south separation for the two hotspots. Exploring this road on hunting days can be a bit disconcerting as the explosions of shotguns can come when you least expect it. Fortunately for me today, it was a quiet, although quite foggy cruise through the wetlands.

We were fortunate enough to see an adult Bald Eagle and a Peregrine Falcon literally on back-to-back telephone poles. Unfortunately one of the few cars to come along the entire route, happened to drive past as I was trying to get a photo of the Peregrine. The conditions were not conducive for stellar photographs, but I did get an identifiable shot of the eagle.

Merced County 2021 eBird Checklist #2 – Merced NWR

2021 Merced County Species-to-Date
Life List = 178
Year List = 76

After a delightful tour around the San Luis NWR – Waterfowl Tour Route, my next destination would be the Merced NWR. Infamous for its auto tour route that takes visitors on a loop through time with thousands of Snow Geese, Ross’s Geese, Greater White-fronted Geese and Sandhill Cranes, this refuge is a true valley treasure. At 226 species, eBird shows the Merced NWR Hotspot is tied with the O’Neill Forebay for the highest number of observed bird species reported in Merced County. The Merced Refuge actually hosts 6 separate eBird Hotspots with 4 for specific trails, one for just the auto tour route and one more general that covers the entire area.

The 4-mile auto route takes visitors through various managed wetland parcels with differing water levels. Following the route in a counter-clockwise navigation around the wetlands immerses us in an immense science lab full of ecologically-connected food webs. With the never-ending treat to life from above, the birds are usually quite nervous. Today would prove to be the exception.

With dark clouds overhead I knew it wouldn’t be long before the rain would fall. As we drove west along the north part of the tour route, a gentle rain began to wet my windshield. It was as if the dark skies and light showers calmed the birds. While the lighting made photography a challenge, the birds continued to feed as if I wasn’t there at all. A Black-necked Stilt probed first one spot, then another and another trying it’s best to stir up a morsel.

Black-necked Stilt

In between the scattered passing of light showers, I captured a few species that wandered within range of my lens.

Long-billed Dowitcher
Cinnamon Teal
Great Egret
Red-shouldered Hawk

I stopped next to a small patch of willows and a small cottonwood when I heard a small woodpecker hammering away at the trunk of the cottonwood. I could see at first glance that it was a Nuttall’s Woodpecker as it peered at me.

Nuttall’s Woodpecker

It seemed non-complused with my presence, pecking away at bark and probing each crevice it could get its bill into. As it came around towards the front of the limb, I could see that it was a female as the nape was not showing any of the bold red pattern that a male would have.

Nuttall’s Woodpecker

Continuing the journey towards the observation platform at the extreme SE corner, we came across several other interesting birds.

Gadwall – female and male
Northern Shoveler – female and male
Western Meadowlark
Ruddy Duck – male
Northern Harrier
Black Phoebe

Finally arriving at the platform that held the most expectations for me, we parked and explored the platform briefly. We both needed to stretch our legs.

I packed Benji back into the car and I went for a walk around the Bittern Trail. Of late, up to two Vermilion Flycatchers have been reported at the refuge, with the last sighting yesterday (1/3/2021). I walked slowly around the trail, taking long, silent breaks, listening and watching for the slightest movement. I noticed (squirrel moment…) a chunky sparrow doing a two-footed scrape-hop in the leaf litter and I just had to try and get a good shot of it. Fox Sparrows come in a variety of forms, or sub-species. The most likely one to be encountered here would be the Sooty Fox Sparrow and I intended on getting proof of which type it was.

Sooty Fox Sparrow

As I searched for over an hour, I spotted a distant Great Horned Owl that flushed as I tried to get closer.

Great Horned Owl

I never did find my target Vermilion Flycatcher so I will have to come back again. As I was approaching the last leg of the auto route along Sandy Mush Rd., I remembered that a Lark Bunting had been reported last month along here. I was fortunate to find it after a short search as it was feeding at the edge of the road with other sparrows.

Lark Bunting
Golden-crowned Sparrow

I ended up doing a complete second tour around the refuge, enjoying the calming feeling that it gave me.

The Quest Begins – 1/4/2021

THE FOCUS IS SET
Part way through last year’s San Joaquin County Birding Push, I began to consider what I would focus on for 2021. The answer was simple, focus on the southern adjacent county to Stanislaus, MERCED COUNTY. A quick check in eBird showed that I had a lot of work to do to get my species list up to a respectable number.

WHERE DO I BEGIN?
As happens frequently when I set out to go birding, the most difficult questions to nail down is where? There are so many options on where to go birding that just setting a starting point can be daunting. I always check the latest posts in eBird and on the listserves to see if something really unusual had been observed, but then it’s just a guessing game.

A CHOICE IS MADE – OWL HUNTING IT IS
As I headed down Hwy 99 enjoying the rousing chords of “Born to be Wild” by Steppenwolf, I decided to try and nail down a Short-eared Owl at the San Luis NWR. I thought the conditions were perfect as the weather was cloudy with rain in the forecast. If I couldn’t find one there, I was pretty certain I would be able to find Tundra Swans. Tundra Swans aren’t particularly rare at the refuge, but… who doesn’t like to see Tundra Swans?

SQUIRREL!
I think that I have something in common with many of my other naturalist friends, there’s always lots of “SQUIRREL” MOMENTS. Yes, I was focused on finding that Short-eared Owl, but who can resist Tule Elks posing in the low dawn sunlight?

TULE ELK

Oh, and also I might have forgotten to mention that I had my birding buddy along. Benji is my Bird Dog 2.0, replacing my BEST BIRD DOG EVER TOBY. I think we’re going to make a great team together!

BENJI

PLAN B – TUNDRA SWANS
Well, the Short-eared Owls were staying hidden from me today, so it was off to the Sousa Marsh at the extreme southeast corner of the refuge.

A … COOT MOMENT?
There was another squirrel moment (or should I say coot moment) along the way as a small flock of American Coots decided to ignore me and just swim right up to the side of the pond they were feeding in.

AMERICAN COOT

Soon we were off again, racing (not really…) to the Sousa Marsh were there were almost 100 TUNDRA SWANS were calmly swimming, feeding and flying across the Sousa Marsh.

TUNDRA SWANS

MOVING ON … ANOTHER SQUIRREL MOMENT
After enjoying the swans and other waterfowl for an hour I decided that I was off-schedule and needed to pick up the pace. I needed (wanted?) to get over to the Merced NWR next to try for the Vermilion Flycatchers that had been reported there. I quickly raced down the roadway at a blazing-fast speed of 20 mph, when my mind told my foot to press REALLY HARD on the brakes because another squirrel moment was unfolding. (It’s a good thing my bird buddy was strapped in securely in the back seat.) EGRETS & HERONS – How could I NOT stop and add more images to by collection of probably 3,000 egret and heron photos? But digital images are free (anyone remember the cost of Velvia slide film?) so why not?

Cassin’s Kingbirds, Lawrence’s Goldfinch and Avian Eponyms

HUNTING FOR PHOTOGRAPHIC DOCUMENTATION

The chase began, as they usually do, with a rare bird email report from ebird on 3/14 by Emilie Strauss about a sighting of a pair of Cassin’s Kingbirds. Cassin’s Kingbirds are rare to uncommon in the county with a pretty limited distribution, mostly along the creeks that feed down from the east side of the Coast Range. In addition to being somewhat rare in the valley, they are also very similar in appearance to the much more common Western Kingbirds. As it turns out, Cassin’s Kingbird also happens to be a species that I clearly needed better photos of, so it became my target bird for this morning’s adventure.

HISTORICAL PERSPECTIVE

Going back to when I first started birding the Central Valley over 30 years ago, Cassin’s Kingbirds were only known to be found at a handful of locations between Fresno and San Joaquin Counties with most observations coming from Panoche Valley and the Tracy Golf Course. My first sighing in Stanislaus County was along the lower entrance of Del Puerto Canyon and my dismal photograph barely shows the identifying field marks.

Cassin's Kingbird

In recent years, in Stanislaus County, they have been seen at more locations and a little more frequently with multiple sightings along Orestimba Rd between Interstate 5 and the Orestimba Creek Bridge. It was in this general area that Emilie reported finding them 3-days prior and it was where I told my car’s GPS that I needed to go. I have visited the Orestimba Creek area before and it is a beautiful riparian setting with one of the largest groves of California Sycamore I know of.

THE CHI-VRRRR GOT MY ATTENTION

The drive over there, on a spectacularly pleasant Spring Morning, had me enthralled with the green scenery and lulled into a peaceful state-of-mind as I listened to some Enya song and I enjoyed a slow drive with my windows down. I wasn’t quite to the spot I expected to find the target birds, but suddenly, my ears yelled to my brain “PAY ATTENTION, THEY’RE CALLING RIGHT NEXT TO YOU”! As I stopped quite suddenly, in the middle of the road, I could hear, not one, not two, but 4 Cassin’s Kingbirds earnestly calling back and forth, giving their rapid CHI-Vrrrr, CHI-Vrrrr, CHI-Vrrrr calls. In fact, there was one on the fence line about 40 yards away, behind me! Yes, I had driven right past it in LaLa land. I knew that given the light conditions, I was going to have to make a U-turn, go well past the birds, and then make another U-turn to get back facing the right direction.

Cassin's Kingbird

Cassin’s Kingbird

KINGBIRD FRATERNAL TWINS

As I had mentioned before, Western Kingbirds, the most expected kingbird for our area, is very similar, at a glance to the Cassin’s Kingbird, both in appearance and in behavior. They both are frequently seen sitting on barbed wire fence lines or electrical/phone lines where they sally forth to snag passing moths and other flying insects. They both sport a sunny yellow belly with grayish heads and backs and longish dark tails. But, as they say, the devil’s in the details. The gray on the Cassin’s Kingbird is darker, with a clearly visible white chin.

Upon further inspection, the tails offer a different combination of buffy edging. While the Western Kingbird has a bold edge along the sides of the tail, the Cassin’s has the buffy coloration at the tips of the tail feathers. Oh, and as my ears pointed out to my brain, the Cassin’s offers a chi-vrrrr, chi-vrrrr, chi-vrrrr rapid call which is quite distinctive and different from the squeaky pidik pik pidik PEEKado call of the Western.

Cassin's Kingbird

A ROSE, BY ANY OTHER NAME…

As I was photographing the kingbirds, a pickup drove up to me and asked what was special about the bird I was photographing. I casually mentioned the kingbirds and how they were similar and different at the same time (avoiding the “Rare” term), and he asked why the one was called “Cassin’s.” And I thought, “What a great question”! I got to thinking about the other “Cassin’s” birds I could think of… Cassin’s Finch, Cassin’s Vireo, Cassin’s Auklet and Cassin’s Sparrow.

Cassin's Finch

Cassin's Vireo

I knew that species were never named by the person that first discovered and wrote up the description of a new species, so that meant the folks in the field finding these “new species” must have had a reason to name their finds after John Cassin. So who was he and what did he do. I went to the interwebs and Googled “John Cassin”

AMERICA’S FIRST TAXONOMIST – JOHN CASSIN

I found an excellent article posted on the California Audubon’s Audublog called, “John Cassin: America’s First Taxonomist.” It is actually a reposting of an article from the Mount Diablo Audubon Society’s newsletter, The Quail. It gives a fascinating account of all the species that bear his name and how he became established as America’s First Taxonomist in the mid-1800s. In short, he was made the honorary curator of the Philadelphia Academy of Natural Sciences where he “discovered” nearly 200 species from the Academy’s collection of specimens.

A LESSON IN AVIAN EPONYMS

When George Lawrence discovered the yellow-bellied, white-chinned, very noisy flycatcher (Tyrannus vociferans) he gave it the vernacular name of Cassin’s Kingbird after his esteemed colleague, John Cassin. John returned the favor by naming a new Goldfinch he “discovered” at the Academy after George, the “Lawrence’s Goldfinch.”
