November 8, 2019 - Rio Grande Valley Birding Festival: Edinburg Wetlands and Quinta Mazatlán

Those of you who have been reading this narrative are aware that I have been falling further and further behind in keeping up the “blog” of my 2019 Peregrination “Big Year”.  Sadly, today marks a milestone:  I am now over one YEAR behind!  I will continue to document my birding year, catch up with my photographs and records, and so forth.  When I finally “finish” 2019, I have plans to turn this “blog” into a more informative page, regarding birds, bugs, fish, plants, geology, and whatever natural history topics rattle my cage.  Thanks for reading so far!

November 8, 2019:

I was able to sleep in for an extra half-hour, before loading up for the 6:30 a.m., Rio Grande Valley Birding Festival Trip to the Edinburg Wetlands and Quinta Mazatlán preserve.

Our trip leaders included Angelina Vasquez, a Valley native who is currently a supervisor at the McAllen Nature Center, and who was kind of quiet but was really good about getting birders on the birds.
Dave Irons and Shawneen Finnegan from Beaverton, Oregon are great trip leaders, and I really enjoy birding with them; Dave can be a welcome ‘taskmaster’ when he’s moving a group of 40 birders and trying to keep on a schedule.
John Brush is a local, the Urban Ecologist at Quinta Mazatlán World Birding Center, has done a lot of bird banding, and was also pretty darned good at getting his scope on birds for the group.
Jorge Montejo guides tours to El Triunfo and other Biosphere reserves in Mexico, was an excellent spotter, and had sharp ears.The Birding Festival has some really top-notch trip leaders!!

We stopped first at the wetlands first to walk around the ponds.  Edinburg Scenic Wetlands has large ponds and smaller water features, birding trails, feeding areas, butterfly gardens, observation platforms and an interpretative center set in some 40 acres of native vegetation and wetlands.

We had great views of a pair of Ringed Kingfishers, as well as hybrid Mottled X Mallard and domestic Muscovy-type ducks.  There was a nice bit of activity at their bird feeders.

At the feeders as well as at some planted flowers, we were treated to a view of a Buff-bellied Hummingbird for my ABA Life Bird No. 658.

Our next stop was at Quinta Mazatlán, a wonderfully restored historical Adobe hacienda.

The old building is surrounded by 15 acres of sub-tropical gardens and native woodlands with birding trails, feeding stations and water features in McAllen, Texas.

There, we searched for a Pauraque, and one of the women from our bus found one just about 10 feet off the sidewalk behind a hedge, and everyone got great looks at it.
This nightjar forages at night in open areas, including quiet roads, catching night-flying beetles, its main prey, by “jumping” from the ground into the air to snatch these slow-flying insects.
The Pauraque was my ABA Life Bird No. 659.

Besides the habitat features and the great birding here, the Preserve does a good job with their interpretive exhibits.





Back at the Convention Center, I had a quick lunch and strolled around the vendors’ booths, then caught a short nap.



This evening I went out with a Festival van driven by Erik Ostrander and Hannah Buschert who hail from Cannon Beach, Oregon to look for parakeets and parrots in Harlingen.  These trips are always popular, since the Rio Grande Valley is the only place in the U.S. where one can see "countable" populations of these two Parrots in Texas.

 We drove through the local neighborhoods and stopped at the corner of Sam Houston and 77 Sunshine Strip, where about two dozen Green Parakeets were flying around the area and were landing on rooftops and in some palm trees.


We continued to another neighborhood at North Third and Davis, where there were a couple hundred Red-crowned Parrots being watched by other vanloads of birders.



The birds were feeding on the fruits of a tree that one of the locals called the “Toothache Tree”, which appears to be Zanthoxylum clava-herculis, the Hercules' club,  or southern prickly ash.
Mixed into the flock were some Lilac-crowned Parrots and a few Red-lored Parrots, as well as an individual that had a lot of yellow in the head.  There was discussion whether this bird had some Yellow-headed genetics in it, or if it was a Red-crowned that had yellow, rather than red (or some other aberrant coloration) in its crown.
If you look at the list of my bird species seen this year, you’ll see that I did “number” the sightings of the Red-lored and Lilac-crowned Parrots.  These species are on my eBird list because I’d seen the Lilac-crowned Parrot and Red-lored Parrot mixed in with the Red-crowns, but they aren’t “ABA-countable” since they’re not yet considered “established exotic species.”  I’ve been pretty much following the somewhat arbitrary “rules” of the American Birding Association.  The TexasBird Records Committee has not chosen to give its “official” blessing on the status of these exotic species, which would lead to their inclusion on the ABA Checklist.  I’ll not add these to my “ABA Life List”, but it was pretty special seeing these birds and a challenge to identify them amongst the horde of parrots.
After we returned, I stayed to listen to Pete Dunne give a talk on the early days of the World Series of Birding Big Day competitions, and some of the ‘war stories’ he had were pretty darned entertaining.  "The World Series of Birding – Stories Behind the Story, Now It Can Be Told"

November 7, 2019 - The King Ranch

I was up and breakfasted in time to meet the 6 a.m. bus for the Rio Grande Valley Birding Festival trip to the King Ranch, led by Ranch employee Tom Langscheid with assistance from Neil Hayward, Jennie Duberstein and hawk expert Bill Clark.

From the Festival brochure:  "The King Ranch is a magical place: One of the largest ranches in the world (larger than the state of Rhode Island).  It is also private property, with limited access for birders.  The Norias Division, known for more resident Ferruginous Pygmy-Owls than anywhere else in the US, is only open to Festival participants at this time of year.  The sandy soils of Norias support extensive areas of grasslands, thorn scrub and live oak woodlands, whose mottes hold the avian treasures we seek.  Lead guides for this trip are specialists for the King Ranch and are passionate and knowledgeable about the role of the ranch and the wildlife it supports.

 
The main ‘target’ species for the trip was of course, the owls.  This is the only site where the Festival guides used recorded calls to elicit a response.  American Birding Association ethics guidelines are to “Limit the use of recordings and other audio methods of attracting birds, particularly in heavily birded areas, for species that are rare in the area, and for species that are threatened or endangered.”  Since this is a relatively ‘remote’ location as far as birders are concerned, the biologist felt that it would be safe for the owl if the tape was judiciously used.

They played a few times for the owls, and we had 2 birds respond to the playback.  One kept well hidden in the mesquite cover.
The other was found out in the open in a live oak, and the birders got great views of the owl.  The Ferruginous Pygmy Owl was my ABA Life Bird No. 592.
The “air plant” on this live oak is Tillandsia recurvata (ball moss), an epiphyte like the related “Spanish Moss” - not a parasite. It draws no nutrition from the tree, just uses it as a place to live. They are often seen on oaks, and are native to Texas and other southeastern States.

We continued around the Unit, birding and seeing how the operation managed the habitat, vegetation, and ‘livestock’.  Santa Gertrudis cattle are a tropical beef breed of cattle developed on the King Ranch in the 1920s.  They were named for the Spanish land grant where Captain Richard King originally established the ranch in 1853.

The King Ranch net wire fencing was developed in 1933 as an innovative fencing method.  There is no barbed wire on the ranch. 
Besides their cattle operations, the Ranch also maintains herds of exotic ‘wildlife’ for their hunting operations.  We did not see the touted Nilgai or ‘blue bull’ antelope Boselaphus tragocamelus, but saw several groups of Impala.

With all of the livestock on the ranch, we found a number of dung beetles Onthophagus gazella.  This species was introduced by USDA scientists in the 1970’s and is now common throughout the state. In parts of Texas, it’s estimated that they remove 80 percent of the cattle droppings.  A big job for a big State.

We also stopped at a more open area, where we got great views of Sprague’s Pipit, which I had recorded as a “Heard Only” Life Bird back in Montana in May, hearing its distinctive vocalizations on a snowy morning.  It’s always good to be able to change a Lifer from “heard-only” to a “crushed" view!

We returned to the convention center where I enjoyed seeing some of the bumper stickers of the (presumed) birders.

I had a bit of lunch, then took in a couple of talks.  The first was Sometimes it Takes a Village: Nesting Harris’s Hawks in South Texas with Andrea Gibbons:

Few birds defer their own reproduction to assist other breeding adults with the raising of their young, but the Harris’s Hawks of the Lower Rio Grande Valley are doing just that. Most nests in south Texas include at least one adult helping the primary breeders to rear offspring. Why do some hawks help? Let’s explore Andrea’s initial findings.

Harris’s Hawks, described by Andrea as “perhaps the coolest birds of prey in the South Texas region”, exhibit cooperative breeding in which more than two hawks are associated with an occupied nest. This phenomenon has been studied in Arizona and New Mexico, but results have been mixed and debated. Recent research by raptor connoisseur, Bill Clark, documented that at least 56% of the Harris’s Hawk groups in South Texas included one or more “extra” hawks attending nests. However, few of the breeding hawks that Bill observed were color marked and he was unable to determine the origin or the roles of extra hawks attending nests. With this project, we intend to employ modern science techniques and to finally solve the mystery of helper Harris’s Hawks at the nest! Importantly, understanding this mystery will provide key information in formulating conservation measures to ensure the unique social system of this very cool raptor is not disturbed by alteration of habitat or other human activities.
To solve this mystery, Bill Clark has teamed up with researchers and students from University of North Texas (UNT) and Cornell University. These researchers have begun to trap and mark hawks with coded color bands, collect blood for DNA analysis, and put up time-lapse cameras at nests all in effort to determine if the helpers are returning young or are unrelated, as well as the evolutionary basis of this unique social strategy. Your donations will greatly help these researchers cover the costs of marking and monitoring hawks, doing the DNA analyses, and obtaining more nest camera systems to closely spy on the secret social interactions of Harris’s Hawks. Any contribution to this project will be greatly appreciated!

This was followed up by:  Sharp-shinned or Cooper’s, a Perplexing Raptor Field ID Problem with Bill Clark

One of the most difficult raptor identification problems in North America is figuring out whether an accipiter is a Sharp-shinned Hawk or a Cooper’s Hawk, whether perched or in flight. Bill’s talk will point out the many differences between these hawks in flight and perched. Dazzle your friends and up your game in the field!

I realized that I’ve likely been making a Lot of ID errors with these two species over the years, and am humbled by learning (re-learning) now what I should have known 40 years ago . . .

I walked through the vendor area, and had put my name into the jar for the King Ranch, winning a bill cap, as well as a ticket to the Ranch Hand Weekend Concert with Mark Chesnutt, which is part of the November 23rd celebration in Kingsville.  I’ll end up giving the ticket to my daughter Becca, who lives in Texas and will enjoy the music.
