What's On:

Spring means the song and antics of woodcocks and snipe

Woodcocks042210Mixdown.mp39 MB
Some of the most interesting mating rituals among our northern birds are the flights of the woodcock and snipe. WTIPs Jay Andersen talks with a local naturalist about “peenting” soaring, freefall and the mysterious warble in the lowlands.
Chel Anderson is a botanist and plant ecologist for the Minnesota Department of Natural Resources. She lives here in Cook County and joins us periodically to talk about phenology or what’s going on in the woods right now. Welcome, Chel.
Hello, Jay.
Let’s talk about birds. Birds are mating, too. Now, of course, there’s lots of birds, but what I’d particularly like to talk about, which is, I think, pretty interesting to most people, and that is the courtship rituals of the snipe and woodcock.
Yeah. These are some of earliest returning birds, and they are very interesting birds altogether. And, as you say, their courtship rituals are quite elaborate. I know Molly had a really nice broadcast recently of the call of the woodcock. We’ll start with the woodcock, which is kind of a “beaam” sound.
Very good!
So, they’re very busy. For their mating rituals, the males like to stalk around on kind of slightly open, brushy, maybe the edge of a field or could be even at the edge of an old gravel pit or any kind of opening in the woods. Part of the reason they like to be more or less in the open is that their courtship, in addition to stalking around and doing that “beaam” call, is to leap into the air and circle ever greater, wider spirals, up into the air about 300 feet. If you’re watching, they really just about disappear from view. When they get to the top, they start singing, and they’re singing this very distinctive, kind of liquid chirping song and they’re singing as they go up, and the they hover at the top of that spiral for awhile, singing away, and then they just tuck their wings and they dive down towards the ground, but they do it in this pattern like a leaf fall. So, if you’ve watched a leaf fall out of a Maple tree or a Birch tree, it’s kind of a zigzag pattern. And so they do these swoops and turns and swoops and turns, back and forth, singing all the time as they drop to the ground. Then, they hit the ground and pretty quick start up their intermittent “peenting” call again, and if there’s a female right there, they’ll kind of do this stiff-legged walk towards her. But, that aerial display and singing is what they’re using to make their mark with the female.
Now this usually happens right around dusk, doesn’t it? Or early in the morning?
Yes, that’s exactly right. Both the woodcock and the common snipe or Wilson snipe are what we would call crepuscular species. So, they primarily do all their courtship displays and interactions with eachother and feeding from just before dawn through first intense light of the day, and then starting at dusk and into the night. In the case of both species, they will do this courtship during the night, especially if there’s a moonlit night; that will be very popular for doing their courtship displays. The snipe has a little bit different take on the whole courtship thing. They like wetter places, so they’re going to be right out in the marshes or near the edges of swamps. Again, more open, shrubby or grass- and sedge-dominated places, not so much in the forested swamps. Their courtship display is very mysterious in the sound that they make, because they take off and fly very fast and incorporate these swooping dives into the circles that they make around their nesting territory. And, as they do the dives, they do the dives with their tail feathers expanded. At the base of their tail there are two feathers that are a little bit different from all the others, and they extend kind of perpendicular from the body. It’s those two tail feathers that, in the dives, the air going past them vibrates them, and it makes this “wooowooowooo” kind of sound. So, if you go out especially at dusk in most any marsh right now, you can listen to that just, very magical and mysterious sound of the snipe. They’re hard to see doing it. If there is still some light and you’re good with your binoculars and with your visual cues, you can pick them up and try to follow them as they go, but they are flying very fast, and there isn’t anything else that sounds like that.

Time for spring singing in the marshes and blooming in the woods

ChelAmphibians041910Mixdown.mp310.22 MB
This is the time of year to hear frogs in the lowlands and start to see wildflowers in the forest. WTIPs Jay Andersen talks with a local naturalist about amphibian songs and a small sweet smelling flower often overlooked on a woodland stroll.

Marsh marigolds

Spring flowers are coming out and so are the beavers

ChelSpring6BloomsBeavers030410Mixdown.mp37.47 MB
This is the time of year we see pussy willows along the roadsides and marsh marigolds blooming in the wetlands WTIPs Jay Andersen talks with a local phenologist about early flowers, migrating birds and the return of ducks to the lakes. It’s also time for beavers to emerge and bask in the sun.

Ruffed grouse

Buds, birds and drumming grouse signal spring

Catkins, tiny flowers and sweet smelling Balm of Gilead are all strong signs that spring is on the way. WTIPs Jay Andersen talks with a local phenologist about changes in familiar shrubs, activity at the bird feeder and drumming grouse.

Red Squirrel

Feeder birds and chasing squirrels – spring is here

Things are changing at and under the bird feeders. Some birds are arriving, some leaving, some changing color. Then, of course there are the red squirrels with their stunning aerial acrobatics.  WTIPs Jay Andersen talks with a local phenologist about goings on at the feeder.

We can’t feel it, but trees give off energy that melts the snow from their bases, creating tree wells. Early spring is also time for wolf mating. WTIP's Jay Andersen talks with local phenologist Chel Anderson about tree wells and courting wolves.

Aspen tress produce sunscreen

As spring approaches we begin to notice subtle changing colors on the hillsides and along roadways. Trees and shrubs are responding to the longer days. WTIP's Jay Andersen talks with a local phenologist Chel Anderson about aspen sunscreen and chemistry in trees.

In late winter the land warms, but the big lake ices up

ChelSpring1_030110Mixdown.mp311.31 MB

Why does the North Shore seem warmer this winter? Temperatures in February were some of the highest in the state. If that’s the case, why is there so much ice out on Lake Superior? WTIP’s Jay Andersen talks with Chel Anderson, a local phenologist, about the interesting ins and outs of late winter and early spring.

Life under the snow

In winter plants may be dormant, but their chemistry works overtime

Dormancy021510Mixdown.mp310.19 MB

We all know animals have various ways of dealing with winter. Some hibernate; some stay active under the snow. Much the same is true for seeds and plants. It’s called dormancy and it has a lot to do with chemical changes, both in the plants and in the rodents that eat the plants. WTIP’s Jay Andersen spoke with a local phenologist about the dormant plant world under the snow.

The winter world beneath our feet

While most of us are skiing, snowmobiling and snowshoeing on top of the snow, there’s a whole world of activity under our feet. This is the subnivean environment. Small rodents and some insects live in this very special place – and the snow below can be a lot different from the snow on top.  Jay Andersen spoke with a local phenologist Chel Anderson about the mysteries and activities of the subnivean world.
