Otter

Bird Rookery Swamp observations
Saturday, May 23 ~ 7:15 am–1:00 pm

“It was a so-so day for birds but a great day for butterflies and mammals, River Otters especially. I saw seven– a family of five and two other individuals in separate places. The family retreated into what was probably their den in two fallen tree trunks, a nice
two-story place. Once inside, there was some grunting and huffing, and two of the juveniles peeked out, one from the second story and one from the ground level (photo). Another young otter was on its own a little past Ida’s Pond and alternated between catching fish and
watching people watch it.

The Water Moccasin was between markers 6 and 3. It was small, perhaps three feet, but it was easily irritated because it was ready to shed its skin. The milky blue eyes meant it was close to sightless, so it over reacted to any movement, sound or vibration. A couple from South
America bicycled by as I was watching the snake; the husband stopped but when his wife heard the word “snake,” she put her head down and quickly pedaled on by. He said snakes were not on her favorite critter list.

Wildfile Q& A: Do all spiders bite, and are they poisonous?

shoreline spider

Shoreline Fishing Spider (Dolomedes triton) By Dick Brewer

 

Q: Do all spiders bite, and are they poisonous?

A: There are two problems with this question: a technicality, and a set of false assumptions.

First, the technicality. “Poisonous” and “venomous” are two different things. No spider is poisonous — harmful to eat, breathe, or touch. Mushrooms are sometimes poisonous, but spiders are not. Spiders are venomous; their toxins are proteins which only work when injected.

Second, all spiders do bite, but most local spiders are harmless because they are not aggressive and will not bite indiscriminately, or their fangs are simply too small to nip through our comparatively thick skin. Just because they are venomous does not mean they are
dangerous to people.

Spider venom does not exist to harm creatures which are too large for spiders to eat, like humans. The purpose of spider venom is to subdue the spider’s prey, almost always insects. In brief, it’s an insecticide.

Nevertheless, all larger spiders with a body length of a half inch or more should be treated with caution. Avoid flicking them away from your body. People allergic to bee stings may react more strongly to the bite of a spider than an ordinary person.

Bees and wasps kill more people in the United States in one year than spiders and snakes combined kill in ten years, and dogs and cats kill or injure more people each year than bees and wasps. Yet most people like dogs and cats and fear spiders and snakes.

Book Release by Bernard F. Master

Bernie Master

IN PURSUIT OF THE WORLD’S RAREST BIRDS

Author Bernard F. Master chronicles his adventures as a medical professional, businessman and legendary birder in No Finish Line.

Yellow-throated Warbler, BRS

Bernard Master is a avid hiker of the CREW Trails, a phenomenal birder, and a great educator. We have been lucky to have him as a leader in our Strolling Science Seminar series. He lead Birding with the Master at Bird Rookery Swamp in March 2015 and will be returning in our 2015-2016 series. Below details Dr. Master’s new book.

No Finish Line, Discovering the World’s Secrets One Bird at a Time, is one man’s epic journey through life as a successful doctor, businessman, lifelong birder and internationally recognized conservationist. Readers will be mesmerized with his travel adventures spanning six continents and 105 countries. He shares his most exciting adventures searching for the rarest birds in the world. He is the first American to see a representative from each of the 229 bird families in the world, as well as Vireo masteri, a bird in Colombia named after him.

Whether he is meeting Queen Noor of Jordan to discuss birds and world conservation or attending a special dinner in his honor with Prince Bernhard of the Netherlands to receive a commendation in recognition of his world conservation efforts, there is always an interesting story to tell. His forays take him to exotic locations including Venezuela where he rediscovered a bird that had been absent for fifty years. Additional adventures include a thwarted kidnapping in Brazil. His quest to see a representative from all the bird families takes him to Rwanda, the Arabian Peninsula, Cameroon and China, providing readers with photos of extraordinary birds and accounts of his 7,800 species to date.

In between birding trips, Dr. Master was busy building two thriving companies, Health Power, Inc. and its sister company, the MEDCenters. His thirty-five year medical career begins with a tour in Vietnam as a battalion surgeon in a combat unit and a year as post surgeon for the U.S. Army’s Military Intelligence School. Obstacles and successes are the narratives he shares outlining the intricacies of founding a healthcare company and ultimately taking it public on the NASDAQ.

“My own life has been one amazing adventure after another with no finish line in sight.” Author Bernard F. Master currently resides in Worthington, Ohio.

No Finish Line, Discovering the World’s Secrets One Bird at a Time is available on amazon.com.

How to ID panthers and tracks

FWC Id panthers

With rainy season around the corner  wildlife tracks will become more visible. Not everyone will see a Florida Panther in their lifetime but they are more likely to come upon their tracks. Though spotting and identifying a track is definitely harder than identifying a Florida Panther itself. Lucky for us FWC came out with a E-Z guide on how to ID panthers and their tracks:

Some of the information you will find in this online document:

  • Florida Panther identification
  • Florida Panther vs Bobcat
  • General track knowledge
  • Panther tracks vs Bobcat tracks
  • Panther tracks vs Dog tracks
  •  Data on Florida Panther sightings

Wildflie Q&A: Florida Black Bears

A Florida Black Bear looks, listens, and sniffs the air. By Dick Brewer

Q: What should people do if they see a black bear on one of the trails?

A Florida Black Bear looks, listens, and sniffs the air. By Dick Brewer
A Florida Black Bear looks, listens, and sniffs the air. By Dick Brewer

A: Florida Black Bears are the only bear species that inhabit Florida. Safety tips are different with different species of bears due to their varying life histories. The following safety tips refer to black bears and not necessarily brown bears, Grizzly bears, or other bear species.

Think of a black bear as a large, stray dog in your neighborhood. Precautions you’d take with a stray dog apply to black bears too. Don’t make direct eye contact (a threat gesture), don’t run, and don’t turn your back to it.

First, make some noise (clapping hands, bell, whistle) so the bear knows that you are there. Surprising any wild animal is not a good thing.

Stand tall and make yourself look larger by raising your hands above your head. Adults should pick up and hold small children.

Then, back away slowly and get a safe distance away from the black bear. Just like dogs, black bears have a chase instinct and will go after something running from them even if they do not mean any harm. Once you are at a safe distance, you can snap a few photos and enjoy the moment.

Black bears in the wild are shy animals and generally not aggressive towards people. Exceptions would be a black bear that is strongly food conditioned and smells any food you are carrying, and a female black bear who is protecting her cubs. If you see a small cub seemingly by itself, back off immediately. The mother black bear is somewhere very close, and she is watching her cub and she is watching you.

A black bear is a large, powerful, wild animal. It pays to be cautious and to not provoke it, so know a little about black bear behavior before meeting one.

If a black bear stands on its hind legs, it’s not a threat; it just wants to get a better look and smell of the situation.

However, stamping its front legs, jaw popping (snapping its jaws together to make a popping noise), huffing (blowing air out of its nose and mouth quickly), or bluff charging (rushing toward a person but stopping before physically making contact) means it is nervous, and you need to back away from the black bear. Allow the black bear plenty of room to escape, which is all it really wants to do.

If a black bear does approach you and attack, hold your ground and fight back.

If camping at CREW, never store food or any heavily scented items (toothpaste, deodorant, etc.) in your tent. Always store it in a hard topped vehicle, hung from a tree at least 10 feet off the ground and 5 feet away from trees, or in a bear proof container that can be purchased at an outdoor recreation store. Food coolers are not bear proof containers. Click here to camp at CREW.

Strolling Science Seminars 2014-2015

We had a great Strolling Science Seminar (SSS) series this season (say that 5 times fast). The SSS series started in 2011-2012 to provide adults with scientific knowledge from local experts. The experts engaged the participants in outdoor scientific study and enabled them to conduct citizen science as part of local, national, and global projects. Each event is filled with laughter, science, and new knowledge.

This year we were lucky to have:

  • Mad Batters of CREW- Kathleen Smith, FWC Biologistbat sss
  • Mosquitoes of the Marsh: The Good, the Bad, and the Ugly- Neil Wilkinson, FGCUmosquito
  • Fire & Water: Primal Forces Shaping CREW Wildlife Habitats- Jim Schortemeyer & Joe Bozzo, SFWMD

010[1]

  • The Gopher Tortoise: How Protecting One Species Actually Protects Hundreds- Dr. John Herman, FGCUjohn herman and group
  • Birding with the Master- Dr. Bernie Master & Tiffany Thornhill, FWC

Birding with the master 2015

We will start planning the 2015-2016 series of strolling science seminars this summer. If you have any ideas, comments, or contacts that you would like to share  for a SSS event please email Jessi Drummond at education@crewtrus.mystagingwebsite.com, or call 239-657-2253. All ideas are welcomed!

Wild File Q & A: Why do owls turn and bob their heads so much?

Q: Why do owls turn and bob their heads so much?

A young Barred Owl watches activity below.
A young Barred Owl watches activity below.
By Dick Brewer

 
A:     Owl eyes are very large. They are so large that they cannot move in their sockets. Imagine having a pair of binoculars up to your eyes and looking straight ahead. If you hear a sound to the side, you can’t see what made it unless you turn your whole head so the binoculars are pointed toward the sound. That’s how an owl sees all of the time.
Without binoculars, you can roll your eyes up or down and move your eyes left or right without moving your head, but an owl can’t. And even when looking forward, owls have a smaller field of vision than people do.

To see what your visual field looks like try this experiment. Hold your arms out with both of your index fingers in front of your nose. While you stare straight ahead, move your arms in an arc toward your sides, still staring forward. When you can no longer see your fingers
stop moving your arms. The arc that your arms made is your visual field and measures approximately 180 degrees.

An owl’s visual field is only about 110 degrees. For an owl to focus well, it must turn its head to get an object into its visual field. In addition, owls often bob their heads up and down to judge distance.
