Canada Geese

You might be able to ignore the increasing amounts of leaves falling from trees, or the suddenly sinking nighttime temperatures. But when you hear the noisy, distinctive honking of a v-shaped flock of Canada geese as they migrate above you, there is no denying that autumn has arrived.

When children visit Irvine’s exhibit hall, they are often most excited to see our lively snakes. They can meet any of the 4 species of native snakes we have, from the corn snake to the leucistic black rat snake. Immediately, these kids step forward and want to get up close. And they have so many questions: “How big does it get? What does it eat? Where does it live? What animals eat it?”

But when adults visit, they often see a snake and quickly take one big step back. And they only have one question: “Is it poisonous?”

Of Maryland’s 27 species of snakes, only 2 are dangerous. But none are poisonous. Not one. And worldwide, few slithering species are poisonous. That’s because the small, select group of non-constrictor snakes that are dangerous are venomous, not poisonous. And it’s an important difference.

Dragonflies

Flying insects are usually annoying. Mosquitoes can bite, leaving itchy red welts. Bees and wasps can sting. Flies are quick to invade your meal at a picnic. But there’s something really magical about dragonflies.

Barred Owl

The rich baritone hooting of my favorite owl species is a characteristic sound in our listening area, where breeding pairs often call back and forth to one another.

Bird enthusiasts quickly learn this easy-to-recognize rhythm with the mnemonic “Who cooks for you? Who cooks for you all?” It is, all bird watchers will tell you, the sound of the magnificent barred owl.

 


We have long been fascinated with the history of the wild birds in our country, so we're excited to get writer and educator Margaret Barker in the studio for a conversation. Margaret is a Chesapeake Bay native with an interest in watching birds. She and her colleagues Paul Baicich and Carrol Henderson published a book called Feeding Wild Birds in America: Culture, Commerce and Conservation

Marsh Rabbits

Aug 9, 2017

A childhood friend of mine once sent me on an official snipe hunt. He lead me out into the woods with a set of ‘magic’ snipe-finding rocks and encouraged me to knock them together while I searched. I wandered around aimlessly for hours just to return to him laughing hysterically at my naiveté. There was no snipe, of course.

So when that same friend told me just last week that he’d seen something called a marsh rabbit swimming in Virginia, I instinctively believed he was ‘pulling my leg.’ I wasn’t even sure I should Google it, lest I realize it was another elaborate practical joke.

But it turns out that searching for information on marsh rabbits was no fool’s errand. They do exist! They do swim. And they even live in our Chesapeake Bay watershed!

As elementary school students, we all learn that leaves contain a pigment called chlorophyll, which colors leaves green. And shortly after, we middle-school scientists usually discover that through a process called photosynthesis, plants can use chlorophyll and energy from the sun to turn carbon dioxide, water and minerals into food.

So it took me by surprise when a recent nature center visitor asked me if plants can eat anything else. “Are there,” he asked me earnestly, “other ways for plants to feed themselves?”

Perhaps surprisingly, the answer is: yes.

On our planet, there is a diverse type of plants that have evolved a very different strategy than the one we learn about as children. These plants, alien as it may seem, can actually eat animals.

One of the greatest things I have from my grandfather is a collection of wooden duck decoys. There are about a dozen different-sized, hand-carved duck pairs. My kids – who often visit my office where the decoys live on a bookcase – like to mismatch all the pairs, placing a bufflehead with a canvasback, a blue-winged teal with a common goldeneye. After the kids leave, I put all the pairs back together, and this time as I placed the male and female mallards side by side, I wondered: why is it that the male duck gets such elaborate, colorful plumage? While the female duck is nearly all light brown, and, frankly, rather drab? At a quick glance, these two look drastically dissimilar, and the untrained eye could think they were not the same species. 

It turns out that differences like these in the same animal species are known scientifically as “sexual dimorphism.” Sexual dimorphism is the condition where the two sexes of the same species, like the boy and girl mallard, exhibit different characteristics – beyond just the differences of their sexual organs. The condition occurs in many animals, insects, birds and even some plants.

Cicadas

Sitting outside on my patio this weekend, my attempts at reading the Sunday paper were thwarted by an unmistakable, buzzsaw-like song.

I could hear, but not see, the culprit. With my kids at my heels, I ascended a nearby pine tree to pinpoint the noise and locate its source. Just a few limbs up, my son found a stout, one-inch long, black-and-green insect loudly calling out. My daughter knew it instantly. It was a cicada.

Red Foxes

There is a very clever animal that lives near my house. It’s so cunning, it knows to wait until my 3 Labradors are inside the house before coming onto my property. And it has a penchant for my chickens.

I could be quick to say that this fox has become my nemesis, with its maddening habit of sneaking in and stealing my egg layers. But the shrewdness with which this fox has outsmarted my chickens, my dogs and even me makes me hold his ingenuity and abilities in high regard.
