The more I write about nature, the more people identify me with the subject. Every week, I get texts and emails with pictures, links to articles and sometimes even a call to get out here NOW… there’s a huge flock of birds at the three way… referring to the intersection of Card Sound Road at Crocodile Lake in North Key Largo. From Ocean Reef, as you turn north on Card Sound Road, it is the first wetland to the right, and is a productive birding spot.

Such was the case on January 31st, about 8:00 am on a really cold morning with overcast sky when I received a call from Jeanette Rivera, naturalist at Ocean Reef, who was heading to work when she spotted a huge congregation of wading birds. She snapped a photo with her iPhone and in it were White Ibis, Great Egret, Cattle Egret, Roseate Spoonbill, White Pelican, Great White Heron, Reddish Egret and Wood Stork. It was just beautiful. Rivera said, “I was in shock that there were so many birds in that one spot! It was really magical… special…I love it!” As you can tell, Jeanette is very passionate about nature. Of the birds present on this morning, the Roseate Spoonbill, Wood Stork, White Pelican, and Great White Heron were a special treat, as they are most typically seen flying overhead, but on this day they were all here! According to Isabella Collamati, Invasive Species Biologist at Crocodile Lake National Wildlife Refuge, ‘time of day, time of year, temperature, and tide would probably be the biggest factors for why they chose to gather that day. It all lined up so that the water was deep enough to host enough prey to keep all parties interested, but shallow enough to make the hunting easier.” The birds diet consists of minnows, mullet, and killifish, and they are pickier about size than species.  Observe how the Reddish Egret hunts. They do a “Crazy Dance” using their wings to shade the water for a better view and then give chase until they can strike their prey. Reddish Egrets differ from other egret species, that simply stand and wait for food to come before they strike.     By the time I arrived, some of the birds had already left, but there were still dozens of birds. I had fun photographing the Reddish Egret and it’s distinctive hunting behavior. As it searched for fish, it would do a “crazy dance” as it jumped and hopped back and forth with outstretch wings raised over its head, peering at the water. The wings cast a shadow so they can see the prey better. The Reddish Egret is also one of the rare egrets, with only 2,000 pairs thought to be breeding in the U.S. A Roseate Spoonbill sat grooming on a red mangrove perch. Not sure it was there because the tide had risen and it’s short legs were no longer able to maneuver in the deepening wetland. Spoonbills have the broadened bill-ends full of nerve-endings, to feel for animals when mud-grubbing.

Though not a wading bird, I saw a Belted Kingfisher hunting near this shallow wetland. The Kingfisher can regularly be seen perched on the power lines along Card Sound Road. Winter and Spring is nesting season for these birds, though I am not sure where these particular birds were from. Historically wading birds nested in the small Keys and nearby mangrove islands, within Florida Bay, far from human disturbances. The Everglades supports 70-90% of all wading bird nests annually. Wading birds initiated approx 89,514 nests in the Everglades in 2021. The wading bird nesting in 2021 was the highest recorded in 80 years.  The Kingfisher often perches along Card Sound Road. Their “mohawk” style feathers on their head give the kingfisher an air of confidence. Nesting success is highly dependent on the availability of fish and waters shallow enough to concentrate the fish, and water just the right level for the birds to wade in. Wading birds are abandoning their traditional nesting grounds in Florida Bay, and are moving north, partly due to increased salinity and the resulting reduction of species of fish that thrive in brackish water. Salinity of the Florida Bay is a problem, and the Comprehensive Everglades Restoration Plan (CERP) is intended to divert more fresh water through Taylor Slough to Florida Bay to improve the bay's health by reducing salinity. On the mainland Everglades, Madeira Hammock and Paurotis Pond, are locations with a reliable amount of birds and also a short field-trip from the Keys. It is very special living near designated wildlife refuges and national parks, but birds cannot read, and can easily settle in parks and gardens with suitable conditions. Or even can be seen flying overhead… This story was told to me by an avid tennis player Pat Holbrook, about a situation that occurred in mid-serve, requiring a “do-over”. As Pat tossed the ball preparing to serve up a winner, she called “let”… there is a Roseate Spoonbill flying over the tennis court. It is rare to see a Roseate Spoonbill, but never had she seen one flying overhead. An unexpected pause, a brief delay of game… and all the players agreed, nature had served up a winner.

“I see said the blind man as he picks up his hammer and saw,” is one of my favorite expressions, where “see” refers to sight or understanding. and the moment when I finally recognize what is going on. It was just a regular trip to the mailbox; on the way I’d glance at the bed of aloe vera plants with their tall bloom spikes, hoping for a hummingbird to hover on by. Surely one day I’d see a hummingbird as each Fall Hummingbirds leave their breeding grounds throughout the Eastern United States, and winter in the Florida Keys. while others take their fly-way South through Texas to Panama.  Ruby-throated hummingbird approaching an aloe vera flower. Surely they were present in my yard. Yet they eluded my vision until I took the time to sit and wait, camera in hand, for the invisible to appear. To say I'm a multitasker would be accurate, while I sit in wait for the hummingbird, the phone rings and now I’m also talking to a client about art work when suddenly I blurt out “Wait wait I gotta go… It's here…” My reaction to spotting my first hummingbird could have been likened to giving birth to my first child. But in a flash it was gone again.  Ruby-throated hummingbird male hovers in midair while sipping nectar. I silenced the phone, and waited with my strict attention on the flowers. In about 10 minutes the bird returned. I lifted my camera, pulled off some shots and I captured that amazing bird approaching, hovering, and nectaring on an aloe flower. The photograph revealed it was a male Ruby-throated Hummingbird (Archilochus colubris), its name referring to the ruby-red feathers on the male bird’s throat.  Firebush (Hamelia patens): a Florida native with orange-red flowers Having finally seen a hummingbird in action, I can truly appreciate these amazing little helicopters, as they swoop down from the treetops, hover in midair while sipping nectar, then zip away all in the blink of an eye. They are so small, about 2-1/2 to 3-1/2 inches, weighing less than a quarter of an ounce, a hummingbird could easily be missed. Perhaps you could hear them coming by the humming sound caused by the rapid beating of their wings… that’s why they are called “humming” birds. Ruby-throated hummingbirds’ wings beat at an amazing 55 beats per second. They have to keep moving since hummingbirds have tiny feet, which is great for aerodynamics, however there's a downside: these birds cannot walk. They can only perch or scoot sideways.  Firecracker plant: with red, tubular flowers, growing 3-4 ft. tall and 6 ft. wide Hummingbirds need to feed every 10-15 minutes which increased my opportunities for getting a photo. They can only feed from dawn to dusk so they must consume more than half their weight in food and 8 times their weight in water. They’ve adapted to survive darkness when they cannot feed by eating as much as they can just before dark. At night, their heart rate and body temperature drop to conserve energy, sort of like a daily hibernation, otherwise they likely would starve. Hummingbirds preferred flower color is orange, red or pink. Their needle-like beaks are specialized for feeding on tubular-shaped flowers, where they eat insects found inside, and with their tongue extending beyond their beak, drink the nectar, as if sipping through a straw.

The aloe plant is rarely mentioned as a nectar plant for hummingbirds, although the aloe bloom is pinkish-yellow and has a tubular shape. Hummingbirds learn by trial and error which flowers give the best results, so the aloe in my yard evidently has passed the taste test. They also like the red Bombax blooms which appear in late Winter/Spring.  Adult Male Ruby-throated Hummingbird o a feeder looking “back at ya”. Photo by: Ed Cox A short while later I resumed the phone call that was interrupted by the bird. Luckily I was speaking with a fellow nature photographer who understood my enthusiasm, and then shared some of his great photos of hummingbirds. I noticed some photos involved feeders which are great for viewing hummingbirds. A feeder is filled with a mixture of 1 part white sugar to 4 parts water. Boil the sugar solution till the sugar is dissolved, then cool.. Since the feeder itself is red, there is no need to add red food coloring. Be careful to avoid placing the feeder in direct sunlight, as this stimulates bacteria growth, and clean the feeder every five days. Though feeders satisfy the sweet tooth, gardening for wildlife is always a better nutritional option, especially if you have a variety of plants which are in bloom at different times.

There is plenty of room for common ground with this discussion… after all who doesn’t want to be healthy? Getting started is half of the problem. Often we place too much emphasis on how disciplined we must be, and set unrealistic goals which become more of a chore than a healthy habit.

Birdwatching has surprising health benefits, and is good for the body and soul. First it is widely accepted that getting out in the fresh air and sunshine is good for your mind, and your body benefits from absorption of Vitamin D. Birdwatchers walk a lot, but not at a fast pace, since there are breaks when you stop and listen and look for birds. The excitement of the search for birds inspires you to walk farther than you normally would. A fitness expert told me that for every 45 minutes of walking, you earn an additional day of life… longevity earned one step at a time!  Female American Redstart in a Seagrape Tree - Blue Hole, Big Pine Key. Photo by: Isabella Collamati My first bird watching experience came two-and-a-half years ago in May during Spring migration. I was helping survey for butterflies, when someone spotted a Cape May Warbler. I took a photo which I later used to confirm the identity, and learn the bird.  American Redstart blends in with the mulch. Spring and Fall are the major times for bird migration. Songbirds fly South in autumn by the millions, including many young birds, some less than three months old. Their sheer numbers are staggering, and it is a great time to get to know a vast number of birds, in both mature and immature development. The Spring migration however is more popular, as the birds have had time to develop adult plumage and work on their repertoire of songs.  A Black and White Warbler probes for insects in the roots of a fig tree. For centuries man wondered about the seasonal movements of birds. Migrating birds move at night guided by the stars, orienting themselves by landmarks and sensing the earth’s magnetic field. Basic information such as how many birds, how high they flew, and where they were going remained a mystery. The earliest researchers extrapolated numbers by viewing the sky and counting how many bird silhouettes were defined when they passed in front of the full moon.  Male Prairie Warbler. Blue Hole, Big Pine Key. Photo by: Isabella Collamati In the last 80 years, thanks to the end of World War II and the donation by the Navy of 25 radars to the National Weather Service, scientists have used weather radar to track migration. Using radar they can now “see” millions of birds cross over the Gulf of Mexico on a non-stop flight of 600 miles. For migratory birds, their life is short and full of perils. Many songbirds live less than two years and 85% of them die during migration. Our role as caretakers of this fragile planet is more important than ever before, to ensure the survival of migratory birds. They need a reliable source of food and water, and lots of it. Though migratory birds may come to bird feeders, their preferred food is found growing on native trees and plants. It is not just the fruit and seeds, but also the insects that are found amongst the leaves and branches. As I write this journal, I am sitting under the large ficus tree… just outside my door… my special place for “wildlife” inspiration.  Cape May Warbler series for insects in a Wild Tamarind tree.

Add to that a pair of binoculars and a field guide, or an app on your phone like Merlin Bird ID (https://merlin.allaboutbirds.org/) and you are well on your way. The best place to start birding is close to home. It may only be for 10 minutes at a time in your backyard or local park or nature area, but you will get to know a few birds that you see frequently. Once you are comfortable with that you can join a birdwatching group which would have knowledgeable participants familiar with good birding spots. The Annual Audubon Christmas Bird Count (CBC) is a great time to start birdwatching. Often times newcomers think they are not knowledgeable enough to participate in the CBC; this is simply not true. What is great about the CBC is that the organizers create teams of individuals having a variety of experience and skill level. There are always participants willing to teach newcomers.
