Intestine seaweed

There’s a species of seaweed that grows along the coast here in Cohasset with the scientific name Ulva intestinalis; so named because it looks like intestines. A common English name for it is Gutweed, though I’d rather call it Intestine seaweed.

Anyway, it’s one of my favorite seaweeds. How could I not like something that looks like little green intestines?

Jack-in-the-pulpit

Today while walking in the Attleboro Springs Audubon Sanctuary, I saw Jacks-in-the-pulpit (Arisaema triphyllum) in bloom. The dramatic striped spathe shelters a spadix on which the flowers are born. This is one of my favorite native flowers — we used to grow them when we lived in the rental share in Concord center — and seeing their blooms today prompted me to learn a little more about them.

According the Extension service of North Carolina State State University, individual Arisaema triphyllum plants can change between male and female from year to year: “This unique plant, which is pollinated by flies and gnats, has the ability to change gender.  A plant that starts out as male can spontaneously change to female the next year and vice versa. …”

Or, according to another source, first year plants only produce male flowers; then the plant becomes hermaphroditic, producing both male and female flowers. In any case, as is so often true, our stereotypical human norms around gender and biological sex being determined from birth do not apply to all organisms (the stereotypes don’t even always apply to human organisms).

A fascinating plant. Makes me want to start growing Arisaema triphyllum again.

Natives

Over the past year and a half, I’ve slowly been learning a little about botany. One of the most amazing things I’ve learned is that somewhere around one third of all plants in the wild are not native where I live here in Massachusetts. And along suburban streets, most of the plants I see are not only non-natives, they are cultivated by humans. The problem with non-native plants is that they do not fit into the existing ecosystem — they may not support native pollinators, or feed native birds, or provide food or shelter for mammals and other animals. The suburbs may look like a green landscape, but in many ways it’s a sterile green landscape.

So I was pleased to discover the “Grow Native Massachusetts” website, which provides resources for people who want to grow native plants. The tag line of the website sums it up: “Every landscape counts.” If you plant your tiny little 1/8 acre yard with native plants, you’ll be helping pollinators and birds. Heck, if you plant a container garden with native plants on the balcony of your apartment, you’ll be helping native pollinators.

Whales

Carol and I went for a day trip to Cape Cod. The first place we went was Sandy Neck in Barnstable. As we walked from the parking lot to the beach, someone said, “Are you here for the whales?”

About 80 North Atlantic Right Whales have been hanging out around Cape Cod. The Cape Cod Canal has been closed once or twice because one or more whales have entered it — a primary cause of North Atlantic Right Whale mortality is vessel strikes. Since there are only about 370 of these whales left in the whole world, it’s worth closing the canal to keep them safe.

We didn’t see any whales, so we walked up the marsh side of Sandy Neck, where we saw the carcass of a pilot whale that had died on the bay side and had been hauled over to this side to rot. After an hour of walking, we crossed back over to the beach. When the ocean came in view, I got my binoculars and started to scan for whales. Almost immediately, I saw two — no, three of them — just at the limit of visibility, where the ozone started to blur things.

Just as I told Carol, one of the whales breached. Given the visibility and the distance, mostly what I saw was the huge black mass of its body coming up out of the water, the water foaming white around it, and what looked like white patches on one side of the animal’s body — right whales do have white markings on their bellies. Carol got her binoculars up in time to see the huge splash it made when it re-entered the water.

We watched for a while longer. We could see the surging water around the whales, and maybe we glimpsed a sight of the black heads. Then they disappeared. Maybe we saw them for 60 seconds, or even two minutes — not a long time, but a very memorable time.

Young owl

I was out for a walk at dusk in nearby Wheelwright Park, and heard a strange sound coming from a nearby tree — a sort of whiny “cheep” kind of sound. I looked up, and there was a juvenile Great Horned Owl about 10 meters up.

The fading light made it hard to see much, but the bird appeared to have well-developed flight feathers. The prominent ear tufts which are characteristic of adult Great Horned Owls were just starting to form. And the plumage was a lighter color than adult plumage. So my guess is that this was a young owl out for one of its first forays from the nest.

As I stood watching it — and trying to take photos with my smartphone — I thought I heard another owl cheeping from a tree farther away. It seems like there were two young owls out trying out their new wings.

Turkeys on the Common

The Parish House of First Parish in Cohasset is directly opposite Cohasset Common. I’ve seen small groups of two or three Wild Turkeys skulking around in the bushes at the edges of the Parish House grounds. But today I saw about fourteen Wild Turkeys making their way across the common, out in the open, as bold as brass.

At least one male was gobbling. They were definitely aware of me, but they seemed to have little or no fear. Breeding season does that to many animals: reduces their level of fear, so they do stupid things.

Come to think of it, male humans are always in breeding season. Which explains so much about Homo spaiens.

Spring chorus

On Friday when I went for a walk in Whitney Woods here in Cohasset, the marshes were silent. On Saturday, I heard a chorus of frogs calling from a couple of marshes and one vernal pool. When I returned on Sunday, the temperature had dropped 20 degrees, from about 54 degrees to the mid-30s. There were a lot fewer frogs calling on Sunday, but some were still singing away. They sounded like a bunch of ducks gabbling together.

Whenever I tried to get close enough to see them, all I ever saw was a circular ripple where a frog slipped underwater. Nevertheless, identification was relatively easy. Here’s the description of the voice of the Wood Frog (Rana sylvatica) in the Peterson Field Guide to Reptiles and Amphibians: “A hoarse clacking sound suggesting the quack of a duck.” Another source says: “from a distance, a chorus [of Wood Frogs] sounds like a gathering of miniature ducks quacking.”

I’ll let you decide if they sound like ducks or not. Here’s my lo-fi audio recording:

Signs of spring

Salix sp.

On my Sunday afternoon walk, I came across a small tree covered with little gray catkins just coming out on some of the twigs. We always called these Pussy Willows, presumably because the trees look like willow trees (Salix sp.), and the small emerging flower clusters, true to their name, look like small furry cats. This is the second native plant I’ve seen in bloom this spring.

As to what type of willow tree this is, I have no idea. Flora Novae Angliae states, “Salix is a difficult genus that displays tremendous phenotypic plasticity.” Meaning it’s hard to identify. Not counting hybrids, there are something like 19 species of willow that grow in Massachusetts, one of which is known by the common name Pussy Willow (S. discolor). But when I tried to follow the “Key for carpellate reproductive material” in Flora Novae Angliae, I got stuck at terms like “Decorticated wood” and “Ovaries glabrous.” If I spent enough time, I could look up all these terms and follow the key. But I think I’ll just call this Salix sp. until I learn more of the technical terms in botany.
