Winter Wildlife Part 2 – Bald Eagles

Winter Wildlife Part 2 – Bald Eagles

Six months ago, they were predicting a colder than normal winter.  In January that seemed to be the case.  We had multiple fronts with high winds and temperatures dropping into the 20s.  But February has been different.  As I type this, it is 62°F and we have had some of the nicest days we have had in a while.  Sunny, low humidity, really nice.  AND THE GROUNDHOG SAW HIS SHADOW!!! So… maybe an early spring? 

With the warmer temperatures I thought we might encounter some of our ectothermic friends (amphibians and reptiles).  On days like we have seen, snakes and turtles will come out from their winter hiding spots to bask in the sun.  Since our early winter article, two cottonmouths have been seen on Santa Rosa Island.  They were both reported as being very sluggish – but that is to be expected – it is still winter, and the temperatures are still low in the mornings.  With that thought in mind we did our February mid-winter hike at Ft. Pickens.

The hike was on February 6.  It was a beautiful sunny day, the temperature was 49°F, light wind from the north.  I will say, in the wind it was a bit chilly, but behind the dunes it was very pleasant. 

Along the trail I noticed a lot of green plants, but nothing was in bloom.  Often the change in temperature can fool flowering plants into blooming early.  However, the pine trees were full of male and female cones.  They were definitely getting ready for pollen season.

I began in the middle of the island in the hardwoods, moving slowly hoping to find a basking snake.  I did not, but I did see numerous woodland songbirds.  I am not a good birder, but I believe there were varieties of warblers, titmice, wrens, and the always present mockingbird.  I did spot a great blue heron on a nest.  Birds are endothermic – and this is their time – a great time to do some birding if you like that.

I took another trail heading towards the beach.  This crossed through more woodlands before reaching the dunes and the shore.  It was in the woodland area I came across a bald eagle nest.  Many of us remember a time when we never saw bald eagles around here.  Now they are becoming more common and nesting all around the bay area.  These awesome birds are similar to dolphins, sea turtles, manatees, and the Blue Angels – you never get tired of seeing them.  It is always an exciting moment when one flies over.

There was no wildlife on the beach that day but there were plenty of tracks.  Mammals, even in the winter, still prefer to move around under the cover of darkness.  I found the tracks of armadillo and raccoon, common mammals on our island, but there was another set that was harder to identify.  The paw had the imprint of a cat (no claws visible) but the track was quite large for a feral cat.  If it was, it was a big cat.  I have seen bobcats in the Gulf Breeze area, and you cannot rule them out, but the pattern of the stride appeared more like an otter.  Otter tracks would be webbed – these were not – so… I am not sure what it was.

Most encounter island mammals by finding their tracks. Photo: Rick O’Connor

Leaving the beach, I returned to the inland trail heading back to the truck.  On this portion of the trail, you cross over ponds just outside the walls of the fort.  As I glanced across the water – hoping for a swimming snake – I saw something else.  It surfaced briefly and then dove again.  At first, I thought it was a diving bird, such as a cormorant or loon, but when it resurfaced, I saw that it was not.  It was an otter.  I had seen otters before in this area, and other pond areas on the island, but – like the bald eagle and dolphin – it is always exciting to see them again. 

Based on this hike, it is still the time of the “warm-blooded”.  Birds and mammals were the creatures most visible.  We will see if this warming trend continues.  Maybe during the late winter hike in March, we will see some of the “cold-bloods” come out.  Maybe it WILL be an early spring. 

Get out and hike – the weather is fine! 

Poor Food Plot Performance – 3 Simple Solutions to Common Problems

Poor Food Plot Performance – 3 Simple Solutions to Common Problems

For many of us in the Florida Panhandle, managing land for and hunting deer are two of the pastimes that we’ll spend the most time and money on each year.  I greatly enjoy spending time in the woods and value the opportunity to fill the freezer with high-quality protein and occasionally hang a trophy rack on the wall.  Managing a deer herd isn’t without its annoyances though.  One of the main complaints I hear each winter from hunters is regarding their food plots not performing as well as they’d like.  While all manner of things could be at fault, there are three common reasons for poor food plot performance and a few possible solutions to each – let’s take a look.

  1. Not doing your soil homework.  Crops of all kinds, winter food plot forages like small grains, clovers, and ryegrass included, perform best when their pH and nutrition needs are met.  The only way to ensure that your food plot plants’ needs are being met is to perform a soil test well before planting.  Soil tests show the actual levels of various nutrients (N, P, K, and other essential elements) and pH in your food plots.  It is important to remember that even if your soil fertility is adequate or you plan to get it there through fertilizer applications, those nutrients are only available for plants to uptake if your pH is correct (a pH of around 6.5 is ideal for winter grasses and legumes).  If your pH is low and needs adjusting, make sure to apply lime several months in advance as it takes time to change your soil’s chemistry.
  • Not harvesting enough deer.  Even when hunters do all the above correctly, forage performance sometimes lags.  This can be a strong indication that too many deer are using the food plot.  Stocking rates for deer are difficult to determine because there are many variables involved (native vegetation in your area, hunting pressure around you, etc.).  However, if exclusionary cages show quality forage growth, food plots are adequately large, and your forage still struggles, it is likely as simple as too many deer using the forage available. Harvesting only a buck or two a year and no does isn’t going to solve the problem either.  In this situation, the solution is often as simple as taking advantage of Florida’s anterless deer harvest periods (doe weekends) to harvest some does, applying for antlerless deer permits if your property meets the qualifications for that program, and filling your freezer with more tasty, nutritious venison. 

While there can be many causes for poor winter food plot performance, most hunters can improve their forage situation by simply soil testing and amending accordingly ahead of planting, enlarging food plots where possible, and harvesting a few more deer than they have previously.  For more information about winter food plots and any other wildlife management topic, contact your local UF/IFAS Extension office.  Happy Hunting!

Overcup Oak – The Best Native Landscape Tree You’ve Never Seen

Overcup Oak – The Best Native Landscape Tree You’ve Never Seen

Haunting alluvial river bottoms and creek beds across the Deep South, is a highly unusual oak species, Overcup Oak (Quercus lyrata).  Unlike nearly any other oak, and most sane people, Overcups occur deep in alluvial swamps and spend most of their lives with their feet wet.   Though the species hides out along water’s edge in secluded swamps, it has nevertheless been discovered by the horticultural industry and is becoming one of the favorite species of landscape designers and nurserymen around the South.  The reasons for Overcup’s rise are numerous, let’s dive into them.

First, much of the deep South, especially in the Coastal Plain, is dominated by poorly drained flatwoods soils cut through by river systems and dotted with cypress and blackgum ponds.  These conditions call for landscape plants that can handle hot, humid air, excess rainfall, and even periodic inundation (standing water).  It stands to reason our best tree options for these areas, Sycamore, Bald Cypress, Red Maple, and others, occur naturally in swamps that mimic these conditions.  Overcup Oak is one of these hardy species.  It goes above and beyond being able to handle a squishy lawn, and is often found inundated for weeks at a time by more than 20’ of water during the spring floods our river systems experience.  The species has even developed an interested adaptation to allow populations to thrive in flooded seasons.  Their acorns, preferred food of many waterfowl, are almost totally covered by a buoyant acorn cap, allowing seeds to float downstream until they hit dry land, thus ensuring the species survives and spreads.  While it will not survive perpetual inundation like Cypress and Blackgum, if you have a periodically damp area in your lawn where other species struggle, Overcup will shine.

Overcup Oak is also an exceedingly attractive tree.  In youth, the species is extremely uniform, with a straight, stout trunk and rounded “lollipop” canopy.  This regular habit is maintained into adulthood, where it becomes a stately tree with a distinctly upturned branching habit, lending itself well to mowers and other traffic underneath without having to worry about hitting low-hanging branches.  The large, lustrous green leaves are lyre-shaped if you use your imagination (hence the name, Quercus lyrata) and turn a not-unattractive yellowish brown in fall.  Overcups especially shine in the winter when the whitish gray shaggy bark takes center stage.  The bark is very reminiscent of White Oak or Shagbark Hickory and is exceedingly pretty relative to other landscape trees that can be successfully grown here.

Finally, Overcup Oak is among the easiest to grow landscape trees.  We have already discussed its ability to tolerate wet soils and our blazing heat and humidity, but Overcups can also tolerate periodic drought, partial shade, and nearly any soil pH.  They are long-lived trees and have no known serious pest or disease problems.  They transplant easily from standard nursery containers or dug from a field (if it’s a larger specimen), making establishment in the landscape an easy task.  In the establishment phase, defined as the first year or two after transplanting, young transplanted Overcups require only a weekly rain or irrigation event of around 1” (wetter areas may not require any supplemental irrigation) and bi-annual applications of a general purpose fertilizer, 10-10-10 or similar.  After that, they are generally on their own without any help!

If you’ve been looking for an attractive, low-maintenance tree for a pond bank or just generally wet area in your lawn or property, Overcup Oak might be your answer.  For more information on Overcup Oak, other landscape trees and native plants, give your local UF/IFAS County Extension office a call!

How to Become an Expert Naturalist

How to Become an Expert Naturalist

Have you ever been on a walk, passed a beautiful flowering bush, and wondered what it was?  Well, wonder no more!  You can become an expert naturalist by using an easy smartphone app, iNaturalist.  With one easy download, you can connect with others to identify species and document their occurrence.

iNaturalist is a community of naturalists, citizen scientists and biologists working together to share observations of biodiversity and map the occurrence.  Parents need to know that iNaturalist is an online community that allows users age 13 and older to share pictures and locations of the living things they see around them. While considered very safe, like any online network, teens should be cautious with sharing.

Getting started is easy.  All you need to do is create an account at iNaturalist.org and download their free iNaturalist app to your smartphone (Android or iOS). You can then start making your own nature observations, upload them to iNaturalist where you can share your discoveries with others, and also let other iNaturalist users help identify what you have seen.

iNaturalist is a great way to connect with nature and generate scientifically valuable biodiversity data.  You can use it for your own personal fulfillment, or as part of a group.  You can even use the project feature which allows you to have a central page that displays all the observations made within a location, or all observations made by a group. Why not organize your neighbors, club, or friends and challenge them to post their observations?

Black Skimmers and Least Terns, state listed species of seabirds, have returned along the coastal areas of the northern Gulf of Mexico! These colorful, dynamic birds are fun to watch, which can be done without disturbing the them.

What is the difference between a seabird and shorebird?

Among other behaviors, their foraging habits are the easiest way to distinguish between the two. The seabirds depend on the open water to forage on fish and small invertebrates. The shorebirds are the camouflaged birds that can found along the shore, using their specialized beaks to poke in the sandy areas to forage for invertebrates.

Both seabirds and shorebirds nest on our local beaches, spoil islands, and artificial habitats such as gravel rooftops. Many of these birds are listed as endangered or threatened species by state and federal agencies.

Adult black skimmers are easily identified by their long, black and orange bills, black  upper body and white underside. They are most active in the early morning and evening while feeding. You can watch them swoop and skim along the water at many locations along the Gulf Coast. Watch for their tell-tale skimming as they skim the surface of the water with their beaks open, foraging for small fish and invertebrates. The lower mandible (beak) is longer than the upper mandible, this adaptation allows these birds to be efficient at catching their prey.

Adult breeding least terns are much smaller birds with a white underside and a grey-upper body. Their bill is yellow, they have a white forehead and a black stripe across their eyes. Just above the tail feathers, there are two dark primary feathers that appear to look like a black tip at the back end of the bird. Terns feed by diving down to the water to grab their prey. They also use this “dive-bombing” technique to ward off predators, pets and humans from their nests, eggs and chicks.

Both Black Skimmers and Least Terns nest in colonies, which means they nest with many other birds. Black skimmers and Least Terns nest in sandy areas along the beach. They create a “scrape” in the sand. The birds lay their eggs in the shallow depression, the eggs blend into the beach sand and are very hard to see by humans and predators. In order to avoid disturbing the birds when they are sitting on their nests, known nesting areas are temporarily roped off by Audubon and/or Florida Fish and Wildlife Conservation Commission (FWC) representatives. This is done to protect the birds while they are nesting, caring for the babies and as the babies begin to learn to fly and forage for themselves.

Threats to these beautiful acrobats include loss of habitat, which means less space for the birds to rest, nest and forage. Disturbances from human caused activities such as:

  • walking through nesting grounds
  • allowing pets to run off-leash in nesting areas
  • feral cats and other predators
  • litter
  • driving on the beach
  • fireworks and other loud noises

Audubon and FWC rope-off nesting areas to protect the birds, their eggs and chicks. These nesting areas have signage asking visitors to stay out of nesting zones, so the chicks have a better chance of surviving. When a bird is disturbed off their nest, there is increased vulnerability to predators, heat and the parents may not return to the nest.

To observe these birds, stay a safe distance away, zoom in with a telescope, phone, camera or binoculars, you may see a fluffy little chick! Let’s all work to give the birds some space.
