Bolivar Flats: The World's Fastest Animal

[Bolivar Peninsula, TX. Dec 2015]

It should come as no surprise that we are so immensely proud of all our technological achievements. And rightly so -- without technology, we are easily outrun, outswum, and outpowered -- our ability to survive in the wild without the fruits of technology would be very severely limited indeed.  

In sharp contrast to the human race, our fellow animals on earth seem perfectly capable of thriving in the raw environment of their habitat -- with nothing more than their god-given appendages and faculties. 

Consider, for example, the Peregrine Falcon. Its explosive combination of speed and power makes this falcon one of the deadliest hunters in the animal kingdom. The Peregrine brings down its prey by air-diving in excess of 240 mph and, what is effortlessly accomplished by the sheer natural prowess of this raptor, can only be matched by us through our clever inventions.

The inspiration, therefore, for this post is precisely "the world's fastest animal" -- the Peregrine Falcon -- which was observed on a recent excursion to Galveston County, TX. Driving south from Houston, through Galveston and then by the Port Bolivar-Galveston Ferry to Bolivar Peninsula, we return to the Bolivar Flats Sanctuary; where, in addition to the the highlighted species, this blogger was witness to an eclectic mix of species including:

• Crested Caracara
• Loggerhead Shrike
• Eastern Meadowlark
• Great Blue Heron
• Savannah Sparrow
• Forster's Tern

We start with the falcon:

The Peregrine was observed having seagull for lunch. This falcon is an avid bird hunter and its speed and power is rightfully legendary.

The Peregrine is a global raptor and found on every human-inhabited continent. 

Three Caracara were also observed at this venue -- unlike the Peregrine, these raptors are known mainly to scavenge.

Loggerhead Shrike is also a hunter but, unlike the Caracara and the Peregrine, it is a predatory songbird and not a member of the raptor family.

Also observed were:

Eastern Meadowlark:

And closer to the water, a Great Blue Heron:

The grasslands nearby harbor sparrows such as this Savannah Sparrow:

We conclude with a Forster's Tern:

The animal kingdom harbors creatures that truly personify the Olympics motto of "Citius - Altius - Fortius" [Latin for Faster - Higher - Stronger]. From the Bar-headed Goose that flies at almost 30,000 feet over the Himalayas to the Peregrine Falcon that is the world's fastest animal at over 240 mph, we share this planet with species that inspire our imagination and earn our respect for the superlative powers they possess so effortlessly and naturally.

Estero Llano: Green Kingfisher, White-tipped Dove and Common Pauraque

[Weslaco, TX. Dec 2015]

We have already sung paeans to the spectacular birdlife of Texas. Yet, it will take another blogful of content to cover all the amazing species that were encountered on a recent winter trip to Weslaco.  

Powerless to resist the avian charms that the Lonestar state has to offer, we succumb again to profiling another installment of specialty species from the RGV (Rio Grande Valley) region (observed at Estero Llano Grande SP) -- species such as: 

• Green Kingfisher
• Common Pauraque 
• White-tipped Dove
• Sapsucker
• White-eyed Vireo
• Orange-crowned Warbler
• Wilson's Warbler
• Yellow-rumped Warbler
• Black-and-white Warbler

Kingfishers are notoriously skittish and the best way to get good views is luck:

This stunning male flew in to land on a snag just as this blogger was calling it quits at Estero Llano Grande SP. 

Pursuit is futile in the case of kingfishers and having one come to you, as was the case here, is the good fortune that occasionally will favor the patiently persistent observer.

The next species, however, far from evading the observer, doesn't even move an inch:
 

This is the Common Pauraque -- a Mexican goatsucker (or nightjar) that is also found across Mexico's Northern border into Southern Texas.

And while the Pauraque doesn't evade observation through movement, its highly cryptic plumage means it could very well be evading observation by hiding in plain sight.
 
More conspicuous species included the White-tipped Dove:

This pigeon is a terrestrial forager and its pink legs and delicate beige coloring contrast with the similar sounding, and much more widespread, White-winged Dove.

Other species observed included Yellow-bellied Sapsucker:

White-eyed Vireo:

Estero Llano Grande also harbored a handful of wintering warblers:

Orange-crowned Warbler showed well. Memorably, its namesake feature was captured in the following photo:

Wilson's Warbler:

Black-and-white Warbler:

And finally, Yellow-rumped Warbler:

A kingfisher that takes flight on the slightest pretext and a nightjar that sits stoically motionless seemingly oblivious to its surroundings -- every species in the birding world offers a study in contrasts. And, perhaps, there are few places better to observe these wonders than the RGV region of Southern Texas.

Shorebirds of the Bolivar Peninsula: Long-billed Curlew, American Avocet and Marbled Godwit

[Bolivar Peninsula, TX. Dec 2015]

The US is blessed with 4 coasts -- the Pacific, Atlantic, Gulf and Arctic coasts in descending length of coastline. However, in winter, richness of shorebird life favors the Pacific and Gulf coasts over the Arctic and Atlantic coasts. 

On the Gulf Coast, Florida and Texas are both highly sought-after for their spectacular shorebirds and waders. In this post, we profile a recent trip to Bolivar Flats Sanctuary on the Bolivar Peninsula in Galveston County, TX, which illustrates precisely why this hotspot is so renowned for world-class shorebirding.

We start with the largest and most imposing of all our shorebirds -- the incomparable Long-billed Curlew:

"Long-billed" is an adjective mostly applied in a relative sense: Long-billed Thrasher has a bill longer than the Brown Thrasher; similarly, Long-billed Dowitcher exceeds Short-billed Dowitcher in bill dimension. Thus, Long-billed Curlew, while obviously accurate in an absolute sense, must also refer to bill superiority in comparison to the other curlews that were once observed in its company, namely the Eskimo Curlew and the Hudsonian Curlew. The Eskimo Curlew, once one of our most abundant shorebirds has long been shot to extinction and the Hudsonian Curlew, while still around, is no longer recognized as a full species and is now classified as a subspecies of Whimbrel. And, compared to their more modestly sized bills, the Long-billed Curlew's bill, which can be more than 8.5" in length, is awesomely massive.

Sadly, the carnage visited on the Eskimo Curlew has not been restricted to it alone. The Long-billed Curlew which in the mid 1800's was still relatively common on the Atlantic Coast in migration has now been extirpated from its former range. It is now best seen on the West Coast as well as the the Gulf Coast but in thinner numbers.    
 

A cursory glance at eBird records over the last 10 years shows that checklists on the Florida coast show sightings of one or two individuals. Compare to Texas, in similar fashion to California, where checklists show high counts of up to 30.

Another large shorebird with a similar plumage pattern:

This is the Marbled Godwit -- immediately recognizable from the curlews due its upturned bill.

Also seen were -- American Avocet:

Wintering plovers such as the threatened Piping Plover:

And Snowy Plover:

As well as common sandpipers such as Dunlin:

Western Sandpiper:

And the ubiquitous Sanderling:

Shorebirds face a dual threat -- conversion of their grassland breeding sites to agriculture and disturbance from beachgoers and their pets at their wintering grounds. Thankfully the menace of market hunting which annihilated shorebird populations in the late 1800's is now largely behind us but new threats abound including environmental degradation (eg., Oil Spills) and food depletion (eg., harvesting of horseshoe crab eggs for bait). Yet, sanctuaries like Bolivar Flats still harbor several signature species, including the incomparable Long-billed Curlew, that offer a glimpse of the former abundance of our shorebirds.

Santa Ana and Vicinity: Least Grebe, White-faced Ibis and Long-billed Dowitcher

[Santa Anna NWR, TX. Dec 2015]


In the words of the renowned actress Elizabeth Taylor: "It's not the having, it's the getting" -- a saying that sums up perfectly the thrill of the chase and how the adrenaline-infused process of acquisition outweighs the placid act of possession. 

In Birding, however, the "not getting" can sometimes be unexpectedly rewarding as well. For example, this blogger was in pursuit of a Northern Jacana (a Mexican vagrant) that had been reported at Santa Ana National Wildlife Refuge in late December. While the Jacana remained stubbornly elusive to attempts at observation, the process of "not getting" nonetheless produced other rewarding sightings including:

• Least Grebe
• White-faced Ibis (from nearby Estero Llano)
• Great Kiskadee
• Long-billed Dowitcher; and,
• Lesser Yellowlegs

 We start with the grebe:

Our smallest grebe with its piercing yellow eyes is a striking sight that lent poetic inspiration to this blogger several years ago during a Lifer moment:

This Worthy Grebe

Would it not have been wise

To recognize spirit over size

This worthy grebe would then boast

Not the prefix "least"; but "most"

Aptly named, this is the smallest Grebe not only in the US but in the entire New World and while it ranges widely across S. America, in the US, it is restricted to Southern Texas [also occasionally seen as a vagrant in South Florida].

An Ibis spied at nearby Estero Llano Grande, on the other hand, evoked a ho-hum response -- a typical knee-jerk reaction that characterizes the observation of a thoroughly familiar species -- the Glossy Ibis. 

However, and this is why bird photography is such a powerful complement to birding -- closer inspection of the image upon return to Michigan underscored the perils of misidentification that can result from perfunctory observation in the field -- for, this is a White-faced Ibis; not a Glossy Ibis! Note the reddish legs and eyes. This "western counterpart" to the Glossy has an odd distribution -- found in the lower half of S. America it is then absent until it resurfaces in Central and Western N. America.

Also seen at Santa Ana NWR were Long-billed Dowitcher:

.. and Lesser Yellowlegs:

In addition to the waders and shorebirds, Santa Ana, which has a checklist of 397 species, is particularly renowned for its birds in passage. 

In the flash visit to this fabled venue that was afforded this blogger, full advantage of the available observation options was not availed. Any trip to the RGV area requires a good 4 to 7 days to fully appreciate the various hotspots and the avian treasures they hold.

We end with Great Kiskadee:  

This blogger's first visit to the RGV area was in 2009. A return visit in 2012 underscored why Southern Texas remains a mecca for the American birding community. And, with or without the odd rarity from Mexico, venues such as Santa Ana NWR and Estero Llano Grande SP continue to enchant.
