Early Sunday morning is the most quiet time for walking out into our local south Florida birding patch, which is adjacent to residential subdivisions. We owe the existence of the preserve to the developers who, to mitigate their damage to the original Everglades, were required to set aside the land in perpetuity as a wildlife and water conservation area.
Few people are up and about. This morning they are not hurrying to work or bringing kids to school. Operation of machinery such as lawn mowers and other power equipment is restricted on Sunday. Yes, the sounds of human activity are much reduced, but it is not truly silent.
In the spring, Northern Mockingbirds may sing very early or even all night when the moon is bright:
In the pre-dawn darkness we are surrounded by the sounds of life, from the mosquitoes humming in our ears, the songs of crickets, grasshoppers, toads, tree frogs and the sweet warbling of geckos. Most birds are not yet singing-- but listen closely to hear the Chuck-will's-widow as it repeats its name in a never-ending cadence, or, overhead... the call of a Common Nighthawk:
A nighthawk is barely visible as it suddenly zooms down and pulls up with a loud "woosh" just over my head. Is it attacking me or the cloud of mosquitoes that I have attracted? Is there a nest or are young birds nearby?
Why did I fail to identify the calls of screech-owls for the first couple of years after I started taking these early morning walks? I think I did hear them but did not distinguish their soft monotone trill from the competing ambient noise of automobiles, airplanes and air conditioners. Now, I not only hear, but also take pains to listen.
Eastern Screech-Owl:
Common sounds become background "white noise" which our brains filter out. One autumn morning shortly after returning from our second home in Illinois I heard but almost failed to recognize the calls of a species which infrequently visits south Florida during migration.
I had become so accustomed to the sound of its voice in Illinois that I did not immediately realize that this American Robin was was out of place, atop a tree along the trail:
If the Moon is bright, Mourning Doves may already be cooing, and Blue Jays calling.
The sky is lighting up. The Northern Cardinals begin their morning chorus almost exactly a half hour before sunrise. At the same time the Chuck-will's-widow stops its chant. Why? Something triggers opposite responses in two different species. Poetically speaking, is it the length of the night, or the strength of the light?
A male cardinal sings from a conspicuous perch, but listen closely...
...the female may join him in a duet:
Still well below the horizon, the sun has created a deepening red glow in the eastern sky. On this spring morning, Jupiter was still visible above the crescent Moon (March, 2019):
When I reach the shore of the lake I enjoy watching the show as the sky changes minute by minute. Photos do not capture all the colors I see: pink, rose, orange, yellow, purple, blue and green and shades in between.
The Thunder Moon of July sinks into the line of storm clouds:
Facing west towards the lake, I am conscious of riding on a sphere which is rotating backward. The shadow of the earth's horizon behind me is moving steadily over my head and falling down in front of me. First rays of the invisible sun tint the eastern sky but do not pierce the darkness of the land on the opposite shore. Reaching the storm clouds over the Everglades, the rays outline their tops before setting their upper reaches on fire.
Before the sun ever gets down to the treetops on the opposite shore, it has illuminated the entire sky.
Then the brilliance of the vegetation is revealed, and suddenly the colors of the sky fade into gray and blue tones.
Most mornings, usually around sunrise, we see one or sometimes two adult Bald Eagles, navigating a perfect course from the vicinity of their nest, located to the northwest, towards the large lake in our subdivision which has a lighthouse on a small island.
Their two eaglets have migrated north to find cooler waters, but the adults choose to stay here all summer. The lake, with its fish, ducks and herons will feed them. They will also keep watch over the nest and chase away any intruders such as Great Horned Owls, Raccoons or crows which could set up housekeeping and claim it as their own.
A young Marsh Rabbit nibbles on the grass and seems to ignore me. Hoping for a nice image, I cautiously mover closer to it, a few steps at a time, stopping to take yet another photo in case it decides to flee.
Yet it allows me to get ever so close before hopping off. Well, "hopping" is not really accurate in the case of this species. Running or, as I see it, galloping (as in "giddy-yap") better describes their mode of escape, as their hind legs are much shorter than those of other rabbit species. They also have big feet with splayed toes to help propel them through the water.
Although closely related to the Eastern Cottontail Rabbit, the Marsh Rabbit does not have white on its tail and its undersides are dull gray, as can be glimpsed in this photo:
(A reader recently asked why their ears were so short, as longer ears normally benefit rabbits and hares in hot climes by dispersing body heat. I could not find a science-based answer, but noted that they usually swim with their bodies underwater and maybe short ears provide less resistance. They also have very sparse fur, which may help keep them cool.)
As the land heats up, the rising air pulls in winds from the ocean to the east, spoiling the mirrored surface of the lake. Moisture in the air condenses into clouds which portend afternoon storms. It looks like it will be just another summer day for south Florida.
Quote from an a pertinent article at this link: How bird-watching could be incredibly beneficial for your mental health
"Perhaps one of the most interesting results of the studies was the fact that even if people rated their depression/stress/anxiety levels high in the mornings, several hours of bird-watching were seen to consistently raise these feelings and helped people to feel much happier in themselves and the world around them.... What’s more, it didn’t matter what kind of birds were spotted; whether these were native birds or all different species and varieties or lots of the same species, the benefits seem to remain the same."

Halloween Pennants and their enemies
We have had a bumper crop of Halloween Pennant dragonflies (Celithemis eponina) here in south Florida. This colorful species is found in most of the eastern 2/3 of the lower 48 States. It flutters almost like a butterfly and is an important food source for many predators up the food chain.
As do other members of the Celethemis (Pennant) group, they typically perch on the top of a stalk or twig, looking like a flag or pennant:
MaryLou looked out of the back window of our home and saw this immature Green Heron next to the lake, stalking furtively through our lawn. At first I was not sure what it was doing and then realized it was catching and eating Halloween Pennants:
This dragonfly lays its eggs in the water amid floating vegetation in our lakes and canals. Here is a pair of Halloween Pennants copulating:
Grackles are especially fond of these creatures, as are many other birds. A female Boat-tailed Grackle chases after the dragonfly:
She rushes over to feed the prize to her hungry fledgling:
This Cattle Egret was capturing and eating Halloween Pennants:
To the north, the Halloween Pennant is active during the warmer months, but it is present all year round in south Florida.
Our small falcons feast on them. Merlins and American Kestrels visit us during the winter and specialize in plucking them out of the air with their talons.
Here, an American Kestrel, eats one:
Spiders catch many Halloween Pennants:
Loggerhead Shrikes also partake in the feast:
Halloween Pennants seem to have expressive faces as they turn their heads and look about. Depending upon how the light catches their compound eyes, they can look green or red or a combination of both:
Looking at our world with a wider lens, this is the canal which separates our populated subdivision from the Wounded Wetlands:
A quiet corner of the canal is a favored place for the dragonflies to deposit their eggs...
...and where this adult Green Heron pursues them:

Distant raptor! Reach for the...
My Kowa spotting scope has been gathering dust the past few years since I started photographing birds with a DSLR camera and long lens. Before I ever considered buying a big camera, I tried digiscoping, shooting photos with my pocket camera through the lens of my scope. At the time, I lived in New Mexico and obtained most of my images through the front windows of our home.
This Ash-throated Flycatcher raised a family in one of my nest boxes:
A Blue Grosbeak perched atop a juniper tree in the front yard:
Am Evening Grosbeak devoured sunflower seeds from our feeder:
My simple digiscopic photo equipment consisted of the spotting scope, a point-and-shoot 2 MP (yes, that 's right only 2 megapixels!) Canon PowerShot A40 camera, and a Durkee's spice bottle with the bottom cut to the size of the camera lens housing.
Our house, at 7000 feet elevation in the Sandia Mountains east of Albuquerque, had a great view of the wooded front yard:
This contraption worked well when deployed in a stationary location with birds that flew in nearby and settled down. However it was a clumsy arrangement in the field, so I usually settled for binocular and scope views without photos. The scope itself is quite heavy, but this was not a problem when I could drive up into the mountains and set it up along the road.
After we moved to Florida I learned the hard way that lugging such a heavy piece of equipment several miles in midsummer heat was very difficult. Then I started using a telescopic lens and DSLR camera. The scope is still useful on the boardwalk during our nature walks, or for viewing the nearby Bald Eagle nest.
The long lens has been a very convenient replacement for my spotting scope. This is the approximate binocular view of a large raptor roosting about a half mile away across the lake in the Wounded Wetlands (420 mm lens on Canon 80D DSLR corresponds roughly to the view through 8-9x binocular):
I was not certain whether this was an Osprey or a Bald Eagle, or maybe a vulture. Blown up on the camera's LCD screen or back home on the computer it was clearly an Osprey. The cropped image is poor, but good enough to identify it as an Osprey:
Binocular view of a small falcon about 1/4 mile away. Is it a kestrel or a Merlin?:
Long lens confirms the ID, a Merlin:
Enough of this long distance stuff. I have gotten some nice close shots these past couple of weeks. Is this Loggerhead Shrike trying to tell me something?
OK, he has my attention!
Gray Squirrel freezes as I walk up:
I think I can see my reflection in its eye!
Butterflies are scarce, but Halloween Pennant dragonflies are numerous:
A birder from The Czech Republic contacted me and wanted to walk in the Wounded Woodlands. I tried to explain to him that they are not very productive, especially at this time of year. I suggested other places he should visit to make better use of his limited time in the US.
He came anyway and seemed to enjoy identifying the local birds. He too is a "patch" birder and has found over 40 species in a small area there over the years. We discussed the value of learning about the habits of common species and the thrill of seeing the occasional unexpected visitor. I shot this photo of a rainbow just as he was identifying a bird very familiar to him, a European Starling:
This White-tailed Doe has a small antler next to her right ear:
The doe reflected nicely as she walked across the flooded prairie:
