A wide spectrum of wildlife, both local and migratory, depend on the rich, natural environment of the Florida Keys, but for most of us, their presence goes largely ignored. Small discoveries, usually while in the presence of “naturalist” friends, led to my interest in writing about nature and often I get alerts regarding wildlife from neighbors. Late February I got an email from a former photography student Mary Lou Krause: "Carol... there is a Great White Heron nesting on the island near our condo. At this time she has her babies. Might be a nice picture.” The island Mary Lou was referring to is a native outcrop of mangroves next to protected mangrove forest. It lies a hundred yards offshore of Pumpkin Cay condominium complex. Though it has no official name. the neighbors call it “Pumpkin Cay Island” because of where it is located. Her condo is a great perch for viewing marine life such as bottlenose dolphin, sting-rays, turtles, brown pelican and this pair of Great White Herons and three babies in their nest. Pumpkin Cay Island checks all the appropriate boxes for ideal nesting bird habitat; it has sturdy branches to build a nest made of sticks, and is surrounded by water, with a seagrass bottom full of fish and crustaceans. Nesting birds feel safe there because of the distance created by the channel between the mangrove island and the sea-walled shoreline. There is some human traffic… small boats tied to cleats, a few fishing stations. the occasional dog walker… but this doesn't seem to bother the herons. The tidal flow from the ocean through Pumpkin Creek provides clear clean water essential for wading birds, who very slowly forage in the shallow water, waiting for a fish to spear with their sharp bills. Herons will hunt during day or night, the most important factor is the varying tidal depth of the water. Mindful not to get too close, for fear of disturbing the birds, I set up my camera with long lens a hundred feet behind the seawall. There was one very large adult heron visible in the nest. It was late afternoon and the soft light lit up it’s feathers in contrast to the green mangroves. I didn’t see the babies right away, but soon noticed yellow beaks and black eyes popping up from beneath the adult’s long light yellow legs. First I saw one rather bold baby, climbing up to the rim of the stick nest, it’s fluff feathers lit by the sun, then a second came into view, and the finally a third, clearly the most elusive, occupied the lowest portion of nest. For the next few days I visited the herons during morning and late afternoon, and was fortunate to get photographs of both adults, in their natural environment, going about their everyday duties. This Great Blue Heron (white morph) nest on Pumpkin Cay Island is in the northernmost range for these birds, exclusively found in the Florida Keys and the Everglades. One morning I could see momma heron patiently waiting on the nest for her partner to return with food, and get a break from tending the nest. Moments before he arrived, she rose up in the nest, stretching her long neck. Soon her mate swooped in and they stood close with necks and chest touching. After a little “mutual appreciation” time, the female flew over to the seawall. As she perched on the seawall, she turned her head in the direction of the camera, with one leg raised, outstretched claws, and looked straight at me, as if to say “Can’t I get a moment of peace?” I loved this photo so much that I printed it life-size, and placed it where I would frequently walk by it, make eye-contact and say “Hi!” This is the largest heron in North America, 39”- 52" tall with a wingspan of 5’10”. The heron made me smile, and it needed more of a name than “big bird.” What better way to get a name than display the heron at an event full of children and adults? I held a contest at the Eco Fair at Ocean Reef, where I was doing a book signing for “Critters in our Midst”. From more than 50 entries, the winner was Katherine Yalamanchilli, age 10. The name suggested was “Pumpkin”, and the three babies: Casey, Lola and Trey. The entry name stood out because it referred to where the heron lives - Pumpkin Cay. Katherine has a room at home decorated with stuffed animals, and she is excited to read “Critters in our Midst”.
Despite the vast changes made by man to modify and occupy the coastline, most species can live nicely in proximity to humans as long as their most basic ecological needs are met: food, shelter and nesting sites. Habitat loss accompanying human development poses a great threat to wildlife, and water quality degradation is harmful particularly for wading birds.

On the way to her boat in the marina, my friend Denise and I we were stopped in our tracks by a large white bird standing motionless on the dock as it scanned for prey. It seemed un-phased by our approach. Even my movements to remove my camera from the bag did not ruffle it's feathers. The bird was watching us, since its eyes are on the side of its head, but also far enough forward, to peer into the water. When Denise began singing I was sure the bird would depart; she defended her actions by declaring “Do you know of any singing predators?” Despite the glare, the surface motion, the mix of seagrass and plastic on the water's surface, the bird knew that two feet below it's perch on the floating dock there were fish. Herons have binocular vision that gives them excellent depth perception, and their eyesight is about three times more detailed than that of man. Their visual field covers 180 degrees in the vertical; a bird standing with its bill horizontal can see fish swimming near its feet. Their stealthy, quick reactions and spear-like bill rewards them with fish which are swallowed whole. This familiar “crane”, which I later identified as the white form of the Great Blue Heron, known as the Great White Heron, or as the “experts” say “White Morph Blue”, is America's largest heron, measuring 46”, and is found along the coasts of southern Florida, the Yucatan Peninsula, and in the Caribbean. The other large white wading bird we see in the Keys is the Great Egret. It has a slightly smaller bill and always has black legs compared to the typical yellow/greenish/pink legs on the white morph blue. At distance with a scope the legs are the best field mark. There are Great Blue Herons in the Keys, and their range extends from Canada south to Mexico and Florida, and even as far as the Galapagos Islands. They are sometimes overlooked simply because they are not as conspicuous as the whites. There is another even less common form of heron, the Wurdemann morph. It’s also known as the intermediate morph where the dark and white forms overlap in Florida, They have the body of a Great Blue Heron, but the white head and neck of the Great White Heron. Many Great Blue Herons have lost their fear of humans, walking on lawns and expecting castoffs from fishermen. Fisherman should make sure they stay clear of the heron’s piercing bill, as well as be responsible for securing their fishing gear, lines, hooks, and lead sinkers. Injuries due to fishing line entanglement are very common in wild bird populations. as birds can get tangled up in that junk while wading and foraging. Broken wings, poisoning, electrical wires, and bald eagles can also cause injuries or death to these birds. So much so, that wildlife rehabilitation emerged as a profession in the late 1980’s. These organizations are made up of professionals, but most rehabbers are volunteers. Laura Quinn, the “Bird Lady” who founded the Wild Bird Center in Tavernier, is seen in these photos taken in 2009, along with philanthropists Barbara and Bob Gintel, releasing a Great White Heron on the edge of the mangroves in N. Key Largo. According to their website, “Our past, present, and future are the direct result of one woman embracing her passion and caring for the environment and wildlife in the Florida Keys.” As human populations grow and more wild habitat is lost, it becomes increasingly difficult to find adequate release sites.
Singing predators? My friend Denise is correct in her theory that man is not a concern for a direct assault, unless in the rare case some idiot decides to shoot a bird. It is the unintended consequences of our actions that pose a threat, Consider the wedding event hosted on a spit of land, formerly mangrove habitat, surrounded by water on three sides. The sounds of singing, and music fill the air, drowning out the bird’s ability to hear a potential predator, and at the same time plastic utensils and wrappers, cups and party balloons are dancing into the sea. Reality check: the plastic junk floating in the water does not come from offshore; it comes directly from the island we live on. Wildlife rehabilitators know the health of our wildlife is a barometer on the health of the environment. Policy makers as well as merry makers, need to consider how their actions may impact wildlife, including pollution of the environment and habitat loss.
