Business – Contact us – with sightings, photos, comments, concerns whatever. This is the place to share – vinalhavensightings@gmail.com . Hey – you can even write your own stuff - more below

 

Tiit trick – click on the photos to make them huge
maybe you want to write something
about ice

 

 
 
 
Idea - Why don’t you write something…or….aren’t we lucky! – Hey, if you have some knowledge*   (and we know you do) or do some research in an area of nature observation feel free to write a paragraph or two about a topic/sighting that you have made and send it in. We’ll print it (or blog it or whatever) and you will get the glory that you deserve! You can use your own words and I can avoid the “you made me sound like an idiot” complaint that I have received twice over the years.  In truth both people made themselves sound like idiots, I was just the messanger. (*editor’s note - passion does not necessarily equal knowledge)

 

 
 
Anyway, (and speaking of writing) we are lucky enough to have some words sent in from the Javier Penalosa on the hot topic of  Skunk Cabbage and the photo placed prominently in a recent  VSR post. Javier’s writing, of course, was inspired by his complaint that I “didn’t write enough spraint” about the darned plant (or something like that), to which I replied “why don’t you write something” (or something like that). Whatever the inspiration, or truth of the matter/story, we are excited to receive writings that others send in – as long as they are not too fluffy.

 
Enough already – here’s some stuff on Skunk Cabbage “in the words of Penalosa”…enjoy

 
the Skunk Cabbage photo
 from earlier this month

The thing punching though the snow in your nice photograph is the inflorescence or flower containing structure of the plant (skunk cabbage, Symplocarpus foetidus). In late winter, responding to signals that are poorly understood (soil temperature? day length? internal clock?) the inflorescence begins to generate heat and grows upward, melting its way through frozen soil and snow so that is can be displayed to insect pollinators.  This  "inflorescence thermogenesis" is known in a few plant species, especially many members of the Araceae or Aroid family.  The Araceae is a family of over 3700 species, mostly occurring in the New World tropics -- the familiar houseplant Philodendrum is a member.  Besides skunk cabbage, we have two other members of the family on Vinalhaven: Jack-in-the-pulpit (Arisaema triphyllum) and wild calla (Calla palustris).  If someone finds duckweed (Lemna) on the island, that would be an additional member of the family.  So, a tropical family with a few temperate zone outliers.

"Goldenrod Ball Gall" - bulbous gall cause by
the larvae of the spotted-winged fly
(Eruosta solidaginis)

 
An amazing amount of heat can be generated by Aroids. A couple of examples: Arum maculatum generates more heat (per gram of body weight) than a flying hummingbird.  A 125g inflorescence of Philodendrum selloum generates more heat than a 125g rat.  The heat in these plants is generated by the exact same mechanism as in animals: respiration or oxidation of food reserves.   It's easy to understand the benefits of inflorescence thermogenesis in skunk cabbage as the plant is thereby able to get an early start on pollination and seed production, but why would it benefit a tropical rain forest Aroid to heat up its flowers?  There has been much speculation about this, but one attractive idea is that the warm flowers of tropical Aroids benefit large insect pollinators (beetles) who need to get their body temperatures up to be active.  The ancestor of our skunk cabbage was undoubtedly a tropical Aroid, so this is yet another example of an adaptation arising for one function to be turned to another.

Oh, the smell of skunk cabbage -- it's supposed to attract pollinating insects, but it's not clear which ones are involved.  Seems like this should be pretty easy to determine, but from what I've read, apparently not. - JP

 
 
 
 
 
 
 

Hot damn that was packed with good wholesome info! Thanks for the words Javier, we hope to get more from JP and others in the future. Here’s a little of what I was able to find about skunk cabbage pollinators – from “Swamp and Bog” by John “who the heck is John” Eastman.

 
SC “...is probably the first pollen source in spring for honeybees (Apis mellifera). Honeybees do not fly well below 65 degrees, but they are sometimes seen inside skunk-cabbage plants when air temperatures drop as low as 42 degrees. The warmth in successive spathes, it is theorized, serve as “heat stops” for the bee, allowing it to restore energy for flights between spathes and to and from the hive. Other pollinators are chiefly flesh flies (Sarcophagidae) and carrion or blow flies (Calliphoridae). These early-season scavengers are attracted by the plants liver-colored streaks and fetid odor, some botanists site this as an example of dung mimicry, which may have evolved as and attractant for these pollinators”
 

 

 
I’m just happy I got to type “dung mimicry” – ain’t that the spraint!

 

 
And speaking of sharing….

Skin Hill Sally – it would be nice to chalk it all up to “location, location, location” but let’s face it Sally Conway has earned all her great sightings over the years by being so nice. She’s good with the feeders and great with the camera, and that’s a winning combination. In-between recent storms Sally had some Bohemian Waxwings in her yard….

And as she feeds the birds she also feeds the predatory…birds. Couple more sharpies showed up in Sally’s yard recently – you know you are onto something when the predators show up – nice ecosystem Sally!
so cute this little dude with the extra spots

John Drury sent in this photo of a Ring-billed Gull and reports a Red-tailed Hawk (2/3) in town and a male Green-winged Teal at the Millrace.

Tip-toe times, good times, otter times
 
 
 
 
 
 
 
 
 
 
 
(2/8) Tip-toe otter -this big guy came cruisin' thru the Tip-toe scene, from the shore, thru the woods and the heart of the cattail marsh and back.
 
 
 
 
running up the hill
It ran up one hill just to mark it's zone, a week later this was presumedly buried in snow.
 
 
 
 
 
 
 
 
 
 
 
Fun to follow it thru the woods, where it went under logs and made some impressive belly slides along straightaways.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
hardy group!

impressive mink belly slide
(2/14) - Tip-toe snowshoe - Red-tailed Hawk, Common Goldeneye, Bufflehead, mink, otter, snowshoe hare, deer tracks. Bubble Rocks.





the mink bounds were pretty close
together - sign of tough bounding
conditions





So after little to no debate, the VLT/MCHT/GMOW snowshoe group opted to snowshoe at Tip-toe Mountain instead of Fox Rocks. The road is plowed to the parking area and that was a major part of the decision.  It was a great walk, with lots of mink trails and slides, otter slides by the coast and bubble rocks (Rhyolite?) in the ledges. Very cool!









not a true belly slide - more of a mink
downhill bound.

"bubble rocks" were like treasures in the snow





no snowshoe is complete without the scope

basin ice
















Basin - (2/17) - When the Basin freezes over - Barrow's Goldeneye, Bufflehead, Black Guillemot, Old-tails, Bald Eagle, Mink tracks, Harbor Seals -

Good morning in the Basin with John, snowshoeing and skiing in to catch some views of a chilly basin.
john at the scope
















frozen basin
deer have been spending lots of time close to shore



tracking from the ferry - one of our favorite parts of winter ferry riding. otters and deer on this crossing...somewhat quiet on the bird front...






otter action on Lairey's
here the otter came out of the water, rolled,
probably marked and then head to the left....

spraintloads of loons are out there











... and then continued to run along the tree line
before banking and belly sliding into the ocean 







deep snow means cool sets are being
developed...














...and that efforts made to traverse require some high energy
who is that masked man?
and that dramatic rescues are made
 Editor’s note – while some folks have been commenting on what a tough winter it must be for deer (not that  anyone seems too overlly concerned for their wellbeing), most have commented on how little wildlife they feel they are seeing. Tough winter for those of us with houses (and refrigerators), the "other species" out there are certainly feeling it as well. There's life under the snow, but there's also life that has to search elsewhere to survive. That said, Great Horned Owls should be just about sitting on eggs any day now!  Woodcocks in about a month! Salamander migration at the end of March! Spring is in the air, or a month to go on the calendar! "11 more hours to go!". Not really sure why this was written.
and lots of laughter can be heard
thank you spiderman! see you out there!
