"What a thousand acres of Silphiums looked like when they tickled the bellies of the buffalo is a question never again to be answered, and perhaps not even asked." -Aldo Leopold
Located in south-central Kansas, Quivira NWR lies within the overlap of the ranges of both Eastern and Western Meadowlarks. We had observed both species (mostly Eastern) in a past trip or two to western Missouri, but Steve and I were immersed in an almost 50/50 mix of the two at Quivira. According to the literature, these guys participate similarly in their respective habitats, although Westerns prefer things a bit drier. Visually, the two species are quite similar and depending on the season may be difficult for even the most experienced birder to be certain of their ID based on solely visual cues. I believe the two images presented here do represent some of these subtle visual differences. The Western appears to be less contrasty and lighter in color overall than the Eastern. Pay close attention to the sub-moustachial area in the two birds pictured. In the western, the yellow from the chin spills over into this area, but remains a clear and distinct white in the Eastern. Lastly, the head stripes of the Eastern are darker than those of the Western.
Western Meadowlark
Advertisement songs and calls are quite distinct between the two species and should always be sought for best identifications. I was quite confident in this knowledge and sure that I had this down until I read recently, that because these are songbirds after-all, and songbirds learn their songs, there may be some similarities – especially where the two ranges overlap. So, maybe the calls are the only true tool we have?
Today’s “From the Garden” spotlight is on another insidious predator, the Minute Pirate Bugs, or Flower Bugs. These true bugs, classified within the Family Anthocoridae, specialize in piercing and sucking the contents of any soft-bodied insects that are roughly their own size or smaller. These prey insects, such as thrips, aphids, caterpillars and their eggs, are important insect pests. I believe the insect pictured in this post falls within the genus Orius.
Ask the average gringo about their perception of Puerto Rico’s climate and habitats and I am sure most would describe heavy rains associated with tropical rainforests. However, due to rain shadow effects from the central mountain chain known as the Cordillera Central, much of the southern coastal regions receive very little direct rainfall. On my first day of exploring southwestern Puerto Rico, I found myself a 20 minute drive west of Ponce in the Dry Forest of Guanica. Guanica receives about 30″ of rainfall per year, which is very close to the annual average for the state of Missouri. However, with the harsher tropical suns, coastal winds and rocky/sandy soils, this amount of precipitation does not go nearly as far in Guanica. This coastal habitat is much more dry-adapted than the comparatively lush Ozark forests of Missouri.
Welcome to Guanica
Typically dense and developed as Puerto Rico tends to be, the entrance to this reserve was literally on the edge of a subdivision, which is where I found myself with an hour to wait near sunrise before the gates where opened. No worries, I grabbed the camera and the binocs and did some of my first real birding on the island. With about 12 named trails of who knows how many total miles, Guanica (~10,00 acres) offers a lot to see, including a Guayacan tree estimated to be over 700 years old. The photo below shows a monument I was to see elsewhere on the island. These identification markers were carved by FDR’s Civilian Conservation Corps (“Las Tres C” in Puerto Rico). I had never given a thought about the CCC’s presence in U.S. territories like Alaska and PR, but it turns out they were quite active in PR – not only building roads and other structures but replanting forests as well. Applauds to these guys for replanting so many trees and helping to set up these reserves. However, along with the National Forest Service the CCC unfortunately participated in bringing exotic, “desirable” trees like mahogany, teak and eucalyptus. Many of these trees were chosen for their fast-growing ability and their tendencies to suck up a lot of water in order to dry out the island. Consequently, in Puerto Rico’s protected natural areas, a significant amount of the forests’ composition is Australian or Asian and completely altered.
CCC-Puerto Rican Style
I parked at the visitor’s center, which is located on the site of an old sugarmill ruins. I was unable to find a single trail sign. I had read the park ranger on duty spoke English, but if the attendant on this Saturday morning did, maybe he was hesitant to do so with the sweaty, ginger gringo who wielded no more than a dozen words of Spanish (see below).
Pathetic Gringo
Always a good idea while out in wild areas, but definitely a good idea in PR is to use a GPS device. Every map I could find was deficient in more ways than one. The GPS unit I found to be the best during my visit was the map app on my iPhone. Also, as you might have guessed, the Guanica Dry Forest is DRY. Bring plenty of water. I thought the three liters I brought on this hike was a bit of overkill. However, at the end of my ~ eight miles of hiking up and down these coastal hills under extreme heat and sun, I was completely dry. I decided to head out on the most promising of the retired forest road trails and it wound up being the one I hoped it was, leading me to the coast where I was to find Fort Capron that was built by Americans in 1898 and is really more of a lookout tower. There is also a lighthouse nearby, but not all that interesting either.
Fort Capron
Okay, enough with the tour guide stuff. Early in the day, I made my first acquaintance with what would turn out to be my favorite bird of the trip – the Puerto Rican Tody. Check it out…
Puerto Rican Tody
I would find these guys all over my travels in southwestern PR. They are related to and behave somewhat like the Kingfishers, are slightly larger than a Chickadee, are nearly as bold as a Kingbird and as brilliantly colored as a Parrot. I captured the one below as it tackled a stick insect.
Puerto Rican Tody
Much of the trails of Guanica are old forest roads that cut through the habitat, mostly along hilltops. Along most of my hike I was faced with thick walls of scrubby vegetation about 10- 20 feet high, often so thick that I was faced with a mere meter or two of visibility. Even though I could hear bird vocalizations, I was often at a lost to see or identify the species. With patience, however, views can be had. Near the fort, where the hillside slopes got steeper and the coast loomed near, I heard what I immediately knew to be cuckoo on their way up to intercept the trail – the Puerto Rican Lizard Cuckoo. These birds were at first so close, I couldn’t possibly get one in the frame without cutting off significant portions.
Puerto Rican Lizard Cuckoo
Towards this end of the reserve I was presented with more open views.
Guanica Hillside
I was quite fortunate to find the quiet and shy Mangrove Cuckoo during this hike.

Abundant in Puerto Rico and across Caribbean coastlines, the Magnificent Frigatebird is a seabird that feeds by catching fish on the wing. This is a long-lived species. The one pictured below is a juvenile.

It seemed that the closer I was to the coast, the drier the habitat became. The Caribbean Sea is just behind me where I stood to take the picture below.
Cactus Scrub
Well, that covers my trip report for the first of three days. Southwestern PR is a great place for the birder-naturalist. Of the approximately 17 or so endemic birds on the island, all but the Puerto Rican Parrot can be found here. Also, highly varied habitats can be visited within short driving distances. Stay tuned for my next day’s trip-log where I will be summarizing my day spent at Cabo Rojo NWR and Salt Flats.
Planthoppers and Leafhoppers are groups of insects collectively found within the insect Order Hemiptera. Both groups have piercing and sucking mouth parts and feed primarily on plant saps and tissues. These groups are highly diverse. I have been able to capture a few of these fascinating creatures with the camera in the backyard, but these are generally the more common species. The insect pictured above is known as a Spittlebug – named for the behavior of encasing themselves as nymphs in a spittle-like mucous for protection.
The Stormtrooper
I’ve said before that there is no such thing as an original idea in fantasy or sci fi. I’ve found that almost every creature or effect you can find to celebrate in these films or books has been taken (consciously or not) from nature, most often from invertebrates or the deep sea.
Planthopper Nymph
This ultra-tiny guy posted above is a planthopper nymph. Often members of this group will have long, colorful waxy lengths of fibers extruding from their tail ends that are used for multiple purposes, including predator avoidance.
Candy Stripers
Many folks who have spent any time in the backyard have surely seen the Candy-striped Leafhoppers, one of the most abundant species in this group. Gorgeously colored and quick to disappear, the two pictured above are busy making more.
I look forward to sharing more photos of members of these groups in the near future.
The demure, upturned bill, the black and white striped pattern and the gorgeous warmly colored head and neck make the American Avocet in breeding plumage unmistakable.
American Avocet
The Avocet is adapted at finding its bread in a variety of scenarios. It can fish by probing the shallows with its needle-like bill tip, but it is equally comfortable at being in over its head and using its bill as a scythe to collect its prey, sometimes while literally swimming.
American Avocets Hard At Work
I have seen no more than four of these guys at a time in winter plumage in Missouri. During four days at Quivira Steve and I observed dozens.
American Avocet
In the above image you can see the large strides in deeper water this bird’s blue, stilt-like legs afford it.
Ants and most flies that are abundant around my milkweed are nectar robbers – providing no pollination services for the plant. I do see flies from time to time that might carry a pollinia, and sometimes a lightweight like the housefly pictured above will get a leg or two stuck and be unable to free itself. That’s what these ants are waiting for. Here we see the ants beginning to dissect their prey while it struggles to free itself.
In nesting season, the Dunlin (AKA Red-backed Sandpiper) is the most strikingly colored of the calidrid sandpipers; however, as the name suggests, in winter this bird is downright plain, grayish-tan. Dun.
Red-backed Sandpiper
This species is considered to be one of the most abundant shorebirds in the world, but they are relatively infrequently seen as migrants in the Mississippi Flyway. Steve and I saw barely a handful this spring in Kansas.
The Dunlin are in the air and all,as by an invisible broom,
are swept into a perfect unison of movement . . .
thousands of leadership birds with the cohesion of one body,
supported from one pair of wings.
At nearly 1300 described species in North America alone, the Long-legged Flies (Dolichopodidae) are ubiquitous, under-studies and totally unappreciated. Little is known about most of this group’s life histories and habits, especially as larvae. These guys are under appreciated because few know or applaud their function as key predators in backyard and agricultural habitats. Both larval and adult forms of dolichipodids eat a wide variety of pest insects, including other flies, mites, aphids, scale insects and beetles.
Dolichos (long) Podis (foot)
I have discerned three Long-legged species in the backyard and have been able to photograph the two pictured in this post. The most well known and common have the multi-colored, metallic luster of the insect in the first photograph, while the other is more earth-toned and with a pair of dark spots on its wings.
Long-legged Fly
Many species in this family are known for elaborate mating dances, equipped with colored flags on their front legs that they use to seduce and entice potential mates. Sexual selection is even at work on the insects. No one escapes…
One dream I have is to visit the tundra nesting grounds of the shorebirds in the arctic of northern Alaska and witness the territorial displays and nesting activities of these fascinating creatures. Probably the species I am most keen on observing would have to be the Pectoral Sandpiper.
Pectoral Sandpiper
The “Pec” looks like a larger, slightly better dressed Least Sandpiper, and are relatively common to see during migration in Missouri. It is when on the nesting grounds when this “pre-lek” species shows its true colors. Watch this video and this video. Their “thunder booming”, reminiscent of a Prairie Chicken, while in flight display is truly impressive and can be heard here:
As the above photo suggests, this is a species more comfortable with its feet in grass than on the sand or mud, such as typically found with other calidrids.
Time Flies Like an Arrow… Hover Flies Like a Flower
Anyone who has spent any amount of time studying flowers in the backyard garden has at some point noticed Syrphid flies. Known as hover flies, flower flies, bee flies and other names, this group is most well known for mimicking bees and wasps (Batesian mimicry). This small guy was captured feeding on my Ohio Spiderwort this spring.
Bee Fly
This is quite the important group of insects. The Syrphids are major pollinators for numerous flowering plants, potentially as important as native bees in this service. Larvae in this group may feed on rotting vegetation and many species will feed on aphids and other plant pests. The rather large bee fly pictured above was found feeding on a Common Milkweed in the backyard.
Syrphid Sensuality
Eating and making baby Syrphids… If it isn’t already on a T-shirt, it should be. I often find these guys doing the Diptera 12-step in my backyard. If we did that, we’d be thrown in jail!
