I am a pro and con guy.
When our family has a big decision to make, they usually ask me to list pros and cons before we make such a decision, it is something I have done since I can remember. It is not that different from the seven-year rule. When faced with a big decision, some native American cultures discuss how this decision will impact their families and the community seven years down the road.

When I first saw the new Florida Fish and Wildlife Conservation Commission’s prohibited exotic species list, I thought of this pro-con / seven-year rule idea. For example, the Meerkat is on the list. A meerkat. Is this a good pet to start off with? Are they easy to maintain? To feed? Are they pets (as in… can you PET them)?
As I thought through my pro/con-seven-year idea, I thought not – but others obviously do. There are a lot of strange exotic pets in the United States and around the world. A species of turtle that I monitor is a pet trade target. The largest markets are China and the United States. I am guessing status is one reason why people chose pro over con. Maybe they do not think of the cons before making this decision, or maybe the pros are more important to them, so they are willing to overcome the cons – I am not sure.
Either way, FWC’s decision to prohibit this new list of species is not because they might make bad pets, rather it is their high risk of becoming invasive. Florida knows all too well how many of these exotic pets become problems in our local ecosystems. Lionfish, pythons, tegus to name a few. By definition, invasive species cause either environmental or economic problems for the communities where they become established – sometimes both. In 2014, the United States spent over 180 million dollars battling invasive species. We just completed our first statewide Weed Wrangle Event where volunteers went into the community and removed as many invasive plants as they could on a single day. The statewide numbers are not out yet, but locally the Six Rivers CISMA spent the morning removing Chinese Privet, Camphor trees, and Japanese Climbing Fern from a popular biking trail in a state park. And we all know, we will have to do it again.

Some say that spending time and money trying to control these invasive is a waste. Others know that not doing so could lead to a serious environmental or economic problem – so the weeds must be pulled, and the animals captured. All scientists and resource managers who deal with invasive species understand their best chance of eradicating them is when they FIRST appear on the scene – Early Detection, Rapid Response (EDRR). This is also the most cost-effective point in the invasion to work on them. However, most citizens do not know about certain invasive species until they are common in the landscape, and many times it is now too late for eradication – time to go into control mode.
One local species we hope we have begun working on soon enough to eradicate is Beach Vitex (Vitex rotundifolia). This plant is not that common statewide and is a potential target for eradication. Many along our barrier islands know of the plant now and, hopefully, will manage it on their property before it becomes widespread and problematic.
It was in this light that the FWC decided to approve a rule that would prohibit selected exotic animals as pets in Florida. These were considered high risk for becoming invasive if they were to escape or were released. This includes:
Mammals: Meerkats, Mongoose, Raccoon dogs, Dholes, Bushtail possums, and Flying foxes
Birds: Diochs, Red-whiskered Bul-Bul, Java sparrow, and Pink starling
Reptiles: Brown tree snake, Yellow anaconda, Beni anaconda, and Deschauensee’s anaconda
It is the hope that through this rule it will be harder to obtain these animals as pets and possible release into Florida’s landscapes. It is also a hope that people will reconsider having such creatures as pets in the first place. The pro-con / seven-year plan should be considered before buying any pet, particularly exotic ones.

The last week of February is National Invasive Species Awareness Week (NISAW). Each year we post several articles about invasive species that are established in the panhandle, and those that are potential threats.
As most of you know, invasive species can be quite problematic. By definition, they are non-native creatures that arrived in Florida via human transportation. Whether intentional or non-intentional, their arrival has caused either an environmental problem, an economic one, or both. Research shows that the most effective method (both with eradication and cost) is detect and treat them early – what we call EDRR species (Early Detection Rapid Response). However, many of these invasives that “hover” just outside of our area do not make our radar until they have become established. It is at this time we begin to recognize their harmful impacts and demand action to battle them. In many cases, it is too late, and you find yourself in a management mode trying to keep the current population under control.
Though south Florida is ground zero for many invasive species problems, the panhandle is not without its issues. The articles will begin posting Feb 25 and run the rest of the week. For those in the Santa Rosa and Escambia County, we will end the week with an invasive species workday – the Weed Wrangle. For this years’ Weed Wrangle, we will be assisting the Florida state park service by removing the invasive Chinese Privet from the Blackwater Heritage Trail in Milton. The Weed Wrangle will be Mar 2 from 9:00 AM until 1:00 PM. We will meet at the Heritage Trail Visitors Center for a brief orientation and then begin to remove privet. The address is 5533 Alabama Street in Milton FL. You can park next to the library or the playground. Please wear closed toed shoes, bring gloves, loppers, and a water bottle.

On a recent trip to Santa Rosa Island, my wife saw two bald eagles flying down the shore of Santa Rosa Sound. Wanting photos of the nest, we searched and found two individuals in a small nest (for an eagle) in a tall pine. One individual was an adult, the other a juvenile.

Seeing bald eagles is like seeing bottlenose dolphins. I do not care how many times you have seen them over the course of your life, it is always exciting. Growing up here, I do not remember these animals in our area. Of course, their numbers suffered greatly during the DDT period, and poaching was (and still can be) a problem. But both the banning of DDT and the listing on the Endangered Species List did wonders for this majestic bird. They now estimate over 250,000 breeding populations in North America and 88% of those within the United States. Florida has some of the highest densities of nests in the lower 48 states. Though the bird is no longer listed as an endangered species, it is still protected by the Florida Eagle Rule, the federal Migratory Bird Treaty, and the federal Bald and Golden Eagle Protection Act.
It was shortly after Hurricane Ivan that someone told me they had seen a bald eagle in the area. My first reaction was “yea… right… bald eagle”. Then one afternoon on my back porch, my wife and I glanced up to see two flying over. Now we see them every year. The 2016 state report had 12 nesting pairs in the Pensacola Bay area. They were in the Perdido Bay area, Escambia Bay area, Holly-Navarre area, and Pensacola Beach area. Many locals now see these birds flying over our coastlines searching for food and nesting materials on a regular basis.

Bald eagles are raptors with a thing for fish. However, they are opportunistic hunters feeding on amphibians, reptiles, crabs, small mammals, and other birds. They are also notorious “raiders” stealing fish from osprey, other raptors, and even mammals. They are also known scavengers feeding on carrion and visiting dumps looking for scraps. Benjamin Franklin was in favor of the turkey for our national emblem because the bald eagle was of such low moral character – referring their stealing and scavenging habit.
The Cornell Lab of Ornithology list the bald eagle as a year-round resident along the Gulf coast, but most of us see them in the cooler months. Their nesting period is from October through May. They select tall trees near water and build their nest just below the crown of the canopy. One local ecotourism operator has noticed their preference for live trees over the dead ones selected by osprey. Eagle nest are huge. A typical one will be 5-6 feet in diameter and 2-4 feet tall. The record was a nest found in St. Pete FL that was 10 feet in diameter and over 20 feet tall! The inside of the nest is lined with lichen, small sticks, and down feathers. One to three eggs are typically laid each season, and these take about 35 days to hatch. Both parents participate in nest building and raising of the young.
Viewing bald eagles is amazing, but approaching nests with eggs, or hatchlings, can be stressful for the parents. Hikers and motorized vehicles should stay 330 feet from the nests when viewing. Bring a distance lens for photos and be mindful of your presence.

No matter how times you see these birds, it is still amazing. Enjoy them.

As we begin our wildlife series for 2019, we will start with a snake that almost everyone has encountered but knows little about – the southern black racer.
The southern black racer differs from other black snakes in its brilliant white chin and thin sleek body.

This snake is common for many reasons.
- It is found throughout the eastern United States
- It is diurnal, meaning active during daylight hours when we are out and about
- It can be found in a variety of habitats and is particularly fond of “edge” areas between forest and open habitat – they do very well around humans.
The southern black racer (Coluber constrictor priapus) is one of eight subspecies of this snake found in the United States. This local variety is a beautiful shiny black. The shine is due to the fact that they have smooth, rather than keeled, scales. It is a long snake, reaching up to six feet, but very thin – and very fast! Most of us see it just before it darts away.
They are sometimes confused with the cottonmouth. It can be distinguished in having a long “thin” body, as compared to the cottonmouths shorter “thick” body. It has a brilliant white chin and the top of the head is solid black. Cottonmouths can be mottled, usually have a cream-colored chin with a dark “mask” extending from the lower point of the chin through the eye. Cottonmouths also have the wide delta shaped head compared the finger-shaped head of the racer. They are also confused with the eastern indigo snake. The indigo is very long (up to eight feet) large bodied snake, and the lower chin is a reddish-orange color. The coachwhip is a close cousin of the racer, found in many of the same habitats. It has a similar body shape, and speed, but is a light tan color with a dark brown-black head and neck.

The juvenile looks nothing like the adult. The young racers hatch from rough covered eggs laid in late winter and early spring. They typically lay between 6-20 eggs and hide them under rocks, boards, bark, and even in openings in the side of homes. In late spring and early summer, they hatch. Their body resembles adults, but their coloration is a mottled mix of grays, browns, and reds – having distinct patches on their backs. This helps with camouflage but often they are mistaken for pygmy rattlesnakes and are killed.
They are great climbers and are found in our shrubs and trees, as well as on our houses and in our garages. Though sometimes confused with the cottonmouth, this snake is non-venomous and harmless. Harmless in the sense that a bite from will cause no harm – but it will bite. Black racers are notorious for this. If approached, it generally freezes first – to avoid detection. If it believes it has been detected, it will flee at amazing speeds. If it cannot flee, it will turn and bite… repeatedly. Again, the bites are harmless, but could draw blood. Cleaning with soap and water is all you need.
They are opportunistic feeders hunting a variety of prey including small mammals, reptiles, birds, insects, and eggs. They also hunt snakes, including small venomous species. Unlike the larger venomous snakes, black racers stalk their prey – many times with their heads raised similar to cobras. When prey is detected, they spring on them with lighting speed. Despite the scientific name “constrictor”, they do not constrict their prey, rather pin it down and wait for it to suffocate.
They do have their predators, particularly hawks. When approached they will first freeze to avoid detection, they may release a foul-smelling musk as a warning, and sometimes will vibrate their tails. In leaf-litter, this can sound very similar to a rattlesnake – not helping with the juvenile identification confusion. One paper reported finding a dead great horned owl with a black racer in its talons. Apparently, the owl grabbed the snake too far back. It killed the snake but not before the snake was able to strangle the owl.
They are hibernating this time of year but will soon be laying another clutch of eggs and we will once again encounter this most common of snakes.
