Dime store kites were never very expensive, but it still seemed like a luxury when I was growing up and it was a rare thing for us kids to see a store-bought kite flying over our neighborhood. An old paper grocery bag (remember those), some cotton string for the corner loops, and two dog fennel sticks cut from the back field provided the basic ingredients for us to make our own. With a little creative cutting and gluing, and the attachment of a tail made from torn strips from a worn-out shirt, it was a thing of grace and beauty and was soon aloft on the wind. On a good day, with the right breeze (not too light, not too gusty), we could run out two full rolls of kite string until the kite was just a speck in the distance. The real challenge was winding all of that string back in after the kite came down across houses, powerlines and fields.
Please forgive the digression but thinking about the topic for this article sent me on a little trip down memory lane. We are fortunate to have two very interesting avian species of kites that grace our summer skies over North Florida. Both are exceptional aerialists but one of them in particular will leave a visual image that is hard to shake. The swallow-tailed kite (Elanoides forficatus) is one of the most impressive birds on the planet with its stark white belly and under-wing coverts, outlined in bold black trim. Its deeply forked tail gives rise to several descriptive names such as split-tailed hawk and fork-tailed hawk, among others. Each spring, swallow-tailed kites migrate in small groups back to their breeding range that extends into the Florida Peninsula and sections of the Panhandle, including several North Florida counties. I’ve seen up to 21 kites flying over the Apalachicola River floodplain during this time of year. Forested swamp habitats along river corridors are particularly valuable for foraging and nesting areas but these graceful flyers are also observed over agricultural fields and pastures where they catch dragonflies and other bugs on the wing; usually dining in the air. Nesting takes place in treetops and young are fed a mixed bag of insects, tree frogs, lizards and small snakes, most snatched from the treetops in flight. Occasionally, the young of other birds are taken from their nests and added to the menu. After the young have fledged from the nest, it isn’t long before our kites head back to their wintering grounds in South America. Young birds can be identified by their less-deeply forked tail, due to the short outer tail feathers.
The other kite that graces our area during summertime is the Mississippi kite (Ictinia mississippiensis); not quite as flashy as its fork-tailed cousin but beautiful in its own right. Adult Mississippi kites are a pearly gray color with darker wings and tail. They are significantly smaller, with a wingspan of about 3 feet (swallow-tailed kites have a wingspan up to 4.5 feet). Wintering grounds are in South America also but the breeding range in the US includes several western states such as Texas, Oklahoma and even sparsely in New Mexico and Arizona. This species is known to vigorously defend its nest by dive-bombing trespassers who get too close.
I see both species flying around my house in Wakulla County and without fail, I pause to appreciate the grace, beauty and tremendous distances covered during annual flights by these long-distance migrants. Keep looking up during our summer months and you may well be rewarded by a glimpse of these two “kites over North Florida.”

This is becoming an annual summer encounter – manatees in (near) the Intracoastal Waterway of Pensacola Bay area. They have been before, it is not uncommon for them to be seen at Palafox Pier Marina, but in the last few years groups of five to nine manatees have been spotted drifting along the shorelines and hanging around docks in Gulf Breeze and the Perdido Key area.

I cannot say what this means but we are not alone with these new visitors along the Gulf coast. There are enough manatee sightings in the lower portions of Mobile Bay that manatee signs have been placed along Magnolia River and a manatee watch hotline has been set up at Dauphin Island Sea Lab. There are at least 40 resident manatees in the Wakulla River. And now, at least in the last two years, small groups have been seen in our area. Concerned whether these manatees were returning to southwest Florida for the winter during the red tide, there were plans to tag some of them – I am not sure if that was done or not.
So, what does this mean for us?
Well, your first thought is the concern over boat strikes. The manatee has actually been protected by Florida law since 1893. Their numbers have increased to 6600 animals and so their status has been changed from endangered to threatened. That said, they are still protected by both the Endangered Species Act and the Marine Mammal Protection Act.
According to an FWC report, in 2018, 824 manatees died in Florida. The top five causes were (1) Natural causes – 27%, (2) Undetermined – 20%, (3) Watercraft – 15%, (4) Perinatal death – 14%, and (5) Unrecovered – 13%.
There were 17 deaths reported from the Florida panhandle. Wakulla (7), Franklin and Escambia (3), Bay, Gulf, Okaloosa, and Walton (1).
Cold stress was the #1 cause of death (7) – Bay, Escambia, Franklin, Okaloosa, and Walton
Followed by boat strikes (4) – Wakulla (2), Escambia (2)
Unrecovered (3) – Franklin, Gulf, and Wakulla
Undetermined (2) – Wakulla
Perinatal (1) – Wakulla
Natural (1) – Wakulla
So far, in 2019 there have been 259 manatee fatalities. The top five causes were (1) Watercraft – 25%, (2) Undetermined – 24%, (3) Cold stress – 15%, (4) Unrecovered – 13%, and (5) Natural – 13%
In the Florida panhandle there have been four deaths so far. Bay County has had two due to cold stress and Wakulla has had two – one was unrecovered and the other was “other” but human related.

So, statewide watercraft are still a big concern. Two of the three deaths in Escambia were boat related. The manatees tend to stay out of the boat channels, so it is recommend boaters remain in the navigable channels while heading to a destination and, when leaving the channel to reach that destination, go idle speed and have a lookout.
Manatees have actually benefitted the management of invasive hydrilla in the Wakulla River. FWC no longer has to treat it – the manatees are eating it all. Pensacola Bay is currently experiencing a bloom of epiphytic (attached) drift algae on the seagrass beds. Maybe, just maybe, the few manatees we see will consume as much algae they can.
I can understand the concern some boaters may have with manatees in the area. However, they do provide some benefits and are the highlight of the day for any local or visitor who may see them. We should welcome them and do what we can, within the law, to keep them safe. If you spot a manatee, please report it to the Dauphin Island Sea Lab hotline: 1-866-493-5803. Or email manatee@disl.org.

I am writing about this animal because, though it is rare to see them, our terrapin volunteers saw two this past week; and maybe you will too.

The Gulf salt marsh snake is one of those, like the eastern coral snake, that is actually common – just rare to see. It is rare to see because (a) it lives in muddy salt marshes, where we rarely venture, and (b) it is mostly nocturnal – and even fewer of us venture into muddy salt marshes at night.
It is in the genus Nerodia, which includes the common water snakes like the banded water snake (Nerodia fasicata). It is a harmless nonvenomous snake. However, because of where it lives, it is often confused with a cottonmouth and is killed. A common name for this snake in Alabama is “bay moccasin”.
Their name is Nerodia clarkii, but it is a subspecies of this group – so the actual name is Nerodia clarkii clarkii. The other two subspecies are found in Florida. The Mangrove salt marsh snake (Nerodia clarkii compressicauda) is found from central Gulf coast of Florida, around the Keys to Indian River County on the Atlantic coast. The Atlantic salt marsh snake (Nerodia clarkii taeniata) has a very small range. Originally reported in Volusia, Brevard, and Indian River counties – due to the northern expansion of mangroves, it is believed to only be in Volusia County now. It is listed as THREATENED both federally and with the state. Our Gulf salt marsh snake is found from central Florida to Texas.

It is a relatively small snake, only reaching a length of around 15-20 inches, though some have been reported at 30 inches. They possess two long yellowish-tan stripes running laterally the length of its body, the only species of Nerodia to do so. Again, they move at night feeding on small crabs, shrimp, frogs, and small fish. During daylight hours they hide beneath the wrack or other vegetation avoiding herons, egrets, and larger blue crabs. Lacking the needed glands, they cannot desalinate seawater the way sea turtles and terrapins can. All of their freshwater comes from their food and from rainfall.
They breed in the spring, possibly why we are seeing them now, and give live birth to about 10 young in midsummer. They are of moderate conservation concern in Alabama due to the loss of salt marsh. The loss of salt marsh habitat and rise of sea level are their major concerns at this point.
I do need to warn you, though it is a small, nonvenomous snake, they will bite. If bitten, soap and water will do the job. For me, and others, it is actually exciting to see them because of their reclusive nature. If you see one while exploring our intracoastal waters, know that you are not in any danger but rather lucky to see this “mystery of the marsh”.

There are five species of sea turtles that nest from May through August on Florida beaches, with hatching stretching out until October. The loggerhead, the green turtle, and the leatherback all nest regularly in the Panhandle, with the loggerhead being the most frequent visitor. Two other species, the hawksbill and Kemp’s Ridley nest infrequently. All five species are listed as either threatened or endangered under the Endangered Species Act. Due to their threatened and endangered status, the Fish and Wildlife Conservation Commission/Fish and Wildlife Research Institute monitors sea turtle nesting activity on an annual basis.
A group checks out a recently hatched sea turtle nest on the dunes in south Walton county in Florida.
Annual total nest counts for loggerhead sea turtles on Florida’s index beaches fluctuate widely and scientists do not yet understand fully what drives these changes. From 2011 to 2018, an average of 106,625 sea turtle nests (all species combined) were recorded annually on these monitored beaches. In 2018, there was a slight decrease in nests with only 96,945 nests recorded statewide. This is not a true reflection of all of the sea turtle nests each year in Florida, as it doesn’t cover every beach, but it gives a good indication of nesting trends and distribution of species.

With spring upon us, the mighty monarch butterflies have begun their long trek to the north from Mexico, looking to time their migration with growth of the milkweed plants in the southeastern United States. Mated monarch females lay hundreds of eggs along their journey, but only two percent of these eggs will survive to become mature caterpillars to carry on the next generation.

Monarch larvae rely exclusively on milkweed for nutrients, so it is of upmost importance that the plants are available to the offspring at the correct time. If the adult monarchs arrive too early, the milkweeds may not have had enough time to grow after late frosts. If they arrive too late, the milkweed vegetation may not support the nutrient needs of the caterpillars. In addition, the milkweeds contain a poisonous toxin, cardiac glycoside, that stays within the caterpillars’ bodies once consumed. This does not harm the larvae, but actually helps them, as it makes the young and adult butterflies taste terrible and makes them poisonous to potential predators.
For these reasons, it is important that we all do our part to support the growth of native milkweed species. Locally, the Monarch Milkweed Initiate at the St. Marks National Wildlife Refuge educates the public about milkweed and monarchs and grows and transplants native milkweed to support the monarchs on their migration.
When planting milkweed, be aware that there is a popular commercialized non-native tropical milkweed species that is not appropriate for the monarchs in our area. This species, Asclepias curassavica, can flower year-round, luring the monarchs to stay and breed in the winter when they should be on their way back to Mexico to escape freezing temperatures. Staying and breeding too long can make the monarchs susceptible to a protozoan parasite, Ophryocystis elektroscirrha (OE for short), that infects the caterpillars when feeding, reducing their lifespan, body mass, mating success rate, and ability to migrate.

Luckily, there are about 21 native milkweed species in Florida. Many native milkweeds in the Florida Panhandle require specialized care when grown for transplanting, as different species have adapted to a range of habitats. The Asclepias tuberosa, commonly referred to as butterflyweed, is considered easiest to grow as they transplant well and thrive in full sun. Others, such as Asclepias perennis, or aquatic milkweed, and Asclepias incarnata, swamp milkweed, must be grown using trays without drain holes, as their “feet” must be kept wet. The Asclepias humistrata, or sandhill milkweed, requires a drier, heavier soil.

Soon, two important ecological surveys will begin in Gulf County, concerning both diamondback terrapins and mangroves.
Florida is home to five subspecies of diamondback terrapin, three of which occur exclusively in Florida. Diamondback terrapins live in coastal marshes, tidal creeks, mangroves, and other brackish or estuarine habitats. However, the diamondback terrapin is currently listed as a Species of Greatest Conservation Need (SGCN).
Diamondback terrapin populations, unfortunately, are nationally in decline. Human activities, such as pollution, land development and crabbing without by-catch reduction devices are often reasons for the decline, but decades ago they were almost hunted to extinction for their tasty meat. The recent decline has raised concern of not only federal agencies, but also organizations and community groups on the state and local levels. Diamondback Terrapin range is thought to have once been all of coastal Florida, including the Keys.

Mangroves, a shoreline plant species of south Florida, are migrating north and are now being found in the Panhandle. Both red and black mangroves have been found in St. Joseph Bay. Mangroves establishment could be an important key to a healthy bay ecosystem, as a factor in shoreline restoration and critical aquatic life habitat.
Currently there is a significant data gap for both diamondback terrapin and mangrove populations. Therefore, there is a great need to conduct assessments to learn more about their geographic distribution.

The Forgotten Coast Sea Turtle Center is partnering with UF/IFAS Extension & Florida Sea Grant to assist in surveying and monitoring diamondback terrapins and mangroves in St. Joseph Bay, and we need your help! UF/IFAS Extension & Florida Sea Grant Agent’s Rick O’Connor and Ray Bodrey are providing a training workshop for volunteers and coordinating surveys for St. Joseph Bay. Terrapin surveys require visiting an estuarine location where terrapin nesting sites and mangrove plants are highly probable. Volunteers will visit their assigned locations at least once a week during the months of May and June and complete data sheets for each trip. Each survey takes about two hours, and some locations may require a kayak to reach.
If you are interested in volunteering for these important projects, we will hold a training session on Monday, April 22nd at 1:00 p.m. ET at the Forgotten Coast Sea Turtle Center (located at 1001 10th Street, Port St. Joe).
