Babies vs Alligators


I am often asked if I worry about alligators. As a hiker and an Everglades tour guide I see them often. In fact we guarantee guests that they will see them on our tour. I never take for granted that we have massive reptilians that can grow more than fourteen feet in length. I understand them and I respect them. I do not worry about them.

Recently my wife and I took our baby for a stroll on a trail next to a marsh near our home. As she pushed the stroller through a muddy portion of the trail I noticed the stroller tracks bisecting an animal’s tracks. There was no mistaking it. A large all­igator had recently crawled from the river, climbed the muddy berm and descended into the pond on the other side. The large webbed feet made deep impressions in the mud and the sinuous trail of its heavy tail drew a perfect impression of an animal walking with a side to side gait.

The alligator was nowhere in sight, nor was it lurking in wait to snatch our baby. It was a hot day and no doubt it simply wanted to get from one body of water to another. Fish, birds, turtles and other prey that are easily chomped and swallowed are typically on the menu. American Alligators (Alligator mississippiensis) often take to the water at the sight of a person and while attacks do happen, there have been only 568 reported in Florida since 1948. Males were involved in 86% of attacks and unsurprisingly, many of those were provoked.

Feeding an alligator often results in an alligator losing its natural fear of people and they are more likely to approach. Swimming in rivers, canals and ponds, especially at night can mimic the sound of injured prey which draws the attention of an alligator. Water hazards on golf courses can be literal hazards as well.  

Having said all of that, the number of fatalities caused by alligators since 1948 is twenty three. The number of babies in strollers chased by alligators? Zero. Am I careful? Yes. Am I worried? There are more important things to worry about.

Willet stay? Willet go?


Willets are seemingly inconspicuous shorebirds that are easily ignored by the general beach going populace. Chances are if you’ve seen a wedding photo on the beach there is probably a Willet skirting the shoreline behind the bride and groom.

Willets (Tringa semipalmata) are often the bird that some kid on the beach is throwing shells at because the bird ignored the bread thrown at it. (Don’t do it kids, especially if my sister is around. She will throw shells back at you.) Willets have more class than to beg like gulls. Come on kids. They eat tube worms, aquatic insects, mollusks and fish.

To most people a Willet is just a drab-colored shorebird, but when it takes flight it has a striking and very obvious white and black color pattern on the underwing that makes identifying and enjoying a bit easier. The pattern isn’t just for our benefit, a flash of wing helps Willets indentify each other from other shorebird species. The preening Willet in the photo is showing a bit of the black and white in the lower right block.

Willets are monogamous during the breeding season. They split time between the Atlantic coast of South America and the east and west coasts of North America. While they grace our beaches, the males and females tend to nest in the vegetation near the shore. The nest is a well-hidden/conspicuous nest which is to say the nest itself is hidden among the reeds and grasses while a tunnel to the nest is more obvious.

The onomatopoetic name Willet is just one of the various calls the bird makes. It sounds very much like the soothing white-noise “ocean” sounds on my baby’s mobile. Will Will Willet. Will Will Willet.

Males help incubate the eggs and feed the young. Despite their mate fidelity, the females take off two weeks before the chicks fledge, leaving the last of the rearing to the male. I don’t know why this is, but with my own 6 month old at home, the thought of it makes me nervous.
