Crops & Clips: Red-shouldered Hawk

The most common diurnal raptor seen on our local Wounded Wetlands is the Red-shouldered Hawk.

When I see a Red-shouldered Hawk in its typical hunting pose it seems to be deep in thought, reminding me of "The Thinker."



Actually this posture provides the best view of its favored prey, which consists of small creatures often hidden in the grass and sedge, only visible from above.


It simply waits until a reptile or small mammal reveals itself. It also takes birds and insects. In our neighborhood I most often find it at the edge of an open wet prairie. This is the north wet prairie in the Wounded Wetlands, after a rain shower:

In riparian areas, frogs, snakes and salamanders are important food items. This adult exhibits its namesake red shoulders as it joins its mate, which is finishing off a frog's leg:

Adults in south Florida exhibit a range of depth of coloration. Most of our local birds are quite bright:

At Corkscrew Swamp in southwestern Florida we saw some very pale specimens (note the leg band):

This past week, I was walking back to my auto after visiting the local Bald Eagle nest when the cries of a Blue Jay alerted me to the presence of an immature Red-shouldered Hawk on a power line a short distance ahead of me. The young bird has brown plumage for its first 18 months of life:

The hawk seemed to be undisturbed by my presence as I moved closer. Although I could not fit the entire subject in my prime lens, I obtained some very nice portraits :

The immature bird lacks the red in its shoulders but shows a distinctive wing pattern. Its outer primaries are light at the base with dark tips, creating a band near its wing tips:

On January 5th we will be leading our next South Florida Audubon "First Saturday" nature walk at Chapel Trail Nature Preserve in nearby Pembroke Pines.

Crops & Clips: Snowy Christmas in Florida

Oh Deer, Christmas is here:

Deer Christmas Card

Deep snow on Miami Mountain in the middle of May, 2010? I looked up and, for a moment, thought I was in Oregon or Washington State!

Snow on Miami Mountain? 20100524

No, the image has not been photo-shopped. This mountain of coral rock was mined from the bottom of a deep flooded quarry about 1 1/2 miles to the south of our home in Miramar, Florida. I'd never before or since seen the stone piled this high. Demand must have been down and they were stockpiling it.

The rocks are rich in phosphate which formed millions of years ago on the floor of the ocean from the shells and skeletons of sea creatures.

Over 15 square miles of wetlands in nearby NW Miami-Dade County have been permitted for rock mining. In addition to the threat to the Everglades ecosystem, groundwater pollution of several nearby water wells is a concern of conservationists. 

The phosphate comes from sediment that was deposited in layers on the sea floor. The phosphate rich sediments are believed to have formed from precipitation of phosphate from seawater along with the skeletons and waste products of creatures living in the seas.

Phosphate rock and its by-product of phosphoric acid are valuable in fertilizer and industrial applications. It is also a source of gypsum for building materials (drywall), but the phosphogypsum produced in Florida is contaminated with radioactive uranium and thorium (and other isotopes including radium) and its use is prohibited domestically. It is thus stacked up indefinitely in dozens of locations. See: The Clock is Ticking on Florida's Mountains of Hazardous Phosphate Waste


We lack snowy mountaintops, but we have dancing Snowy Egrets:

Small discoveries

When I am out in the Wounded Wetlands of western Broward County, Florida, I do not have high expectations that some rare bird will suddenly brighten my day. 

Actually, working a "patch" might seem boring, yet I have recorded ("officially" per eBird) 171 bird species here since I started regularly posting trip reports in October, 2009. All but a handful were also photographed on-site. A number of species were seen rarely or sometimes only once.

An immature Reddish Egret appeared in the spring of 2011 and remained for only two weeks. This species prefers brackish estuaries and rarely wanders inland:

Another "one-off" species was actually represented by two captive-reared juvenile Whooping Cranes from Wisconsin which overshot their normal wintering grounds in northern Florida:

Whooping Crane 12-15 at 0849AM  20130207

A flock of 15 American Goldfinches, a species which winters in south Florida irregularly, arrived once on December 9, 2015 and departed the same day:

American Goldfinch 4-20151209

To date I have submitted a total of 1,307  eBird checklists, of which 860 have been from my local patch, a hotspot officially known as the West Miramar Water Conservation Area (WCA).
My eBird West Miramar WCA Life List

New additions to the list have decreased over time. I had seen a total of 80 species by the end of 2010, added 27 more in 2011, 13 in 2012, 14 in 2013.  8 in 2014, 15 in 2015, 6 in 2016, 3 in 2017, and only four species (Gray Kingbird, Royal Tern, Chipping Sparrow and Yellow-throated Vireo) this year to date. ADDENDUM (December 13) Only an hour after posting this I added a fifth new species at 6:30 AM, when we heard an  Eastern Whip-poor-will calling just as we started our walk!


Am I succumbing to the Law of Diminishing Returns? Is the "gain not worth the pain?" Time to quit and stop wasting energy?

If my walks were only about counting birds I might certainly get bored. More importantly, they are a time to observe and enjoy the beauty and mystery of nature.

No two sunrises are alike... Pink clouds and fog on November 25, 2018:

Behaviors are interesting and sometimes unexpected. There is the thrill of the sudden appearance of a Bobcat, deer or even a Coyote...

...and of finding beauty in the commonplace and the smallest of things.

Who would have known that there is a moth which resembles a wasp? Polka-Dot Wasp Moth-Syntomeida epilais:

The smallest of our dragonflies also imitates a wasp, waving its wings slowly in a very menacing manner.  Eastern Amberwing - Perithemis tenera:

I bumped into a wild pea plant with seed pods which rattled with a sound like pebbles rolling in a paper cup. I learned that is is quite poisonous. Flowers and fruit of Smooth Rattlebox, Crotalaria pallida:

Later I found an unusually beautiful red patterned moth which requires that same plant to host its larvae, which themselves are protected by the noxious substances they ingest. Bella or Rattlebox Tiger Moth -Utetheisa bella:

I admire the delicate beauty of the flowers of the Bent Alligator Flag, a plant related to members of the Arrowroot family: bananas, cannas and the Bird of Paradise. Their zig-zag stems reach up as high as 8 feet.

Tiny insects are lured to their blossoms and are momentarily trapped and dabbed with pollen before being released so they may cross-fertilize other flowers. 

The insects attract Palm Warblers:

Purple Gallinules eat the flowers and seeds:

I learned that this plant serves as host to a particular butterfly species, the Brazilian Skipper, whose leaf-rolling caterpillars also  inflict great damage to cultivated cannas and other members of the Arrowroot family:
