The mystery revealed: Owlets
Thanks to everyone who ventured a guess. It was fun reading through all the responses, which fell into four main groups: spongy moth egg masses, mammal fur, some sort of filamentous fungus, or owlets. Cue the drum roll...
Mystery photo!
While out at Rock Point this morning, I stumbled across a strange "thing" attached to/growing out of/clinging on to the trunk of a big-toothed aspen trunk. The clump about the size of a large grapefruit and about 15' up the trunk. So what is it?
Big Night(s)!
In like a lion, eh, Spring? The weather has been totally fantastic here in Burlington. We've got garlic shoots coming, grackles moving through in big numbers, house finches with nesting material see image below), and buds starting to green up on our lilacs. But of all the spring phenology events, my favorite is amphibian migration. My friend Ian sent me photos from some Eastern newts and spotted salamanders moving last night by North Beach. And it looks like we could be in for another early Big Night this year. The weather looks perfect at this point for a big movement of amphibians tomorrow night (Friday, March 26)!! Read on for more.
Shrinkadees: What is a species?
When I was writing about chickadees last week, I kept thinking to myself: “What really is a chickadee?” Yes, I know what they look and sound like, but do our diminutive black-capped chickadees really have the same “black-capped chickadee-ness” as those slightly larger 19th century chickadees? And if our Vermont chickadees continue to shrink, at what point do they reach that critical morphological/genetic tipping point where we no longer classify them as Poecile atricapillus and instead mark them as some novel new species, perhaps P. minimus or P. anthropocenii?
Shrinkadees
This morning there was a chickadee in my backyard singing, “Hey Sweetie”. It had fluffed up its feathers, so it looked just slightly more intimidating than it would otherwise. Puffed or not, this was still a small bird, likely weighing about as much as a AAA battery. More than just being small relative to this naturalist, this early morning chickadee was about as small of a chickadee as you’ll find during the year.
Nesting smallmouth bass
I finally got back in the water for some early summer snorkeling. The surface of the lake was rather murky from all the pine pollen that's in the air right now, but the water was relatively clear below and so visibility was somewhat decent. And now that the water's above 60º, the smallmouth bass have all come up for the spawn and so I got to spend some time with my old friends!
Nesting Carolina wrens
A few years ago I enclosed my front porch and built some cubbies to store my running shoes. It wasn't long after that the Carolina wrens discovered the cubbies and started building their nests tucked away in my shoes. This happened three years in a row, but the nests never had any eggs in them. While my shoes don't smell particularly nice, wrens don't have a well-developed sense of smell and don't seem to respond much to the scent of predators (and I don't think my shoes smell any worse than mink urine and feces: source). The behavior always struck me as odd - why go through all that trouble and put in such a big investment of energy to build a nest and not even use it? Here we look at some of the adaptive reasons a bird might build multiple nests.
That’s a lot of fur
A friend game me a challenge a bunch of years ago of finding any spot in the woods, sitting down, and not getting up until a I found a wild animal hair’s within arm’s reach. It was a great challenge, and on my first attempt took me about an hour to complete (it’s possible that the hair I found may have been one of my own). I often think about the ubiquity of lost hairs when out tracking animals in the woods, especially in the spring when some fur bearers molt. This weekend I came across a trail of deer tracks littered with fur and wondered just how hard this challenge is. So this week I’ll describe your odds of finding a deer hair in the woods and next week I’ll describe why deer hair is amazing.
Should You Pee When You’re Cold?
I felt cold yesterday while out at the Field School. It was a different kind of cold from today’s cold, wetter, less biting, but cold nonetheless. We were talking with the kids about ways to stay warm in the cold, and one of the suggestions that came up was that peeing would help you stay warm. This made me curious about the relationship between pee and cold weather and other creative ways I might be able to stay warm.
Orange Balls On Powerlines
Everytime I drive I-89, I notice those bright orange balls attached to the power lines that cross the interstate to the Bolton Falls Hydro Station (map). It seems an odd marker as there are plenty of other places where power lines cross the interstate or other major roads but aren’t adorned with these plastic orange ornaments. Not surprisingly, the visually obvious orange balls, called power line marker balls, are intended to make power lines visually obvious to pilots, particularly in places where airplanes and helicopters tend to fly at low altitudes (like around airports, mountain passes, deep valleys, or even on larger bodies of water where a float planes might land). The balls were invented in the early 1970s by Arkansas governor, Winthrop Rockefeller, who noticed their potential danger during the landing of a flight with Arkansas’ head of the Department of Aeronautics.
