Wordless Wednesday: Northern Shrike

Before the shrike.



Three views of the shrike.

After the shrike.

Birding at my bird feeder tree is over because of this robin-sized predator. Everyone has disappeared. The snow is unbroken now. No silly squirrels, no chattering chickadees, not even a sad mourning dove or brassy woodpecker, redpoll or blue jay. They know how bad this little bird is. He appeared on Monday. See my Northern Shrike post for more information.

Sophie Feels Poorly

Sophie, the doggie garbage can, got into something bad and was vomiting all day and night on Sunday. Yesterday her stomach calmed down but she was tired. She spent the day on the couch, just like this, with Amelia who knit the day away. Today the vet said Sophie had "one of those things." Hope she is right.

Cats Tuesday: We Have Temptations

I finally bought Temptations for them today.
Buddy was a bit slow and kept biting my fingers instead of the Temptations.

The dogs thought Temptations were for dogs.
What a pain they were!

Possum ate them so fast I never got a photo of them on the counter.

Buddy, as always, was very persistent in order to get as many as possible.



He figures if he looks pretty, he'll get more.

Thank you for visiting.

Be Careful What You Wish For? A Northern Shrike

A Northern Shrike showed up this afternoon. It just sat in the bird tree all by its lonesome. All other birds and squirrels had run away (no doubt screaming). Why? The shrike is a predator songbird and it eats little birds and mice and hangs their dead bodies in the trees for snack time.

I have to thank Gilliam of Blossoms and Birdsong in Ottawa for her confirmation of my identification of this bird. Her comment can be read in the comments. She has also sent me an article, "Oh, No, There's a Hawk At My Feeder", which gives valuable information on what to do if a predator stops by.

According to the Cornell Lab of Ornithology site, All About Birds, "The Latin species name of the Northern Shrike, Lanius excubitor, means 'Butcher watchman.' " Very descriptive. The shrike is such a pretty bird and yet is a butcher.

I took these photos from across the living room. I was afraid to get close to the window immediately because some birds (like mourning doves and unlike chickadees) will fly away when they see you at the window. Or when the camera's green light focuses on them. I did not know how the new bird would react, so as I crept across the living room floor towards the window, I kept snapping photos. When I finally reached the window, it flew to the other side of the tree and then flew away.

The sun set soon after the shrike flew away. The only animal to return was a mouse who appeared from a tunnel in the snow to eat the seeds scattered by the morning's birds. My photos of the mouse did not come out well at all.

I am wondering if tomorrow anybody shows up. The blue jay might return, the mourning doves probably. But not the chickadees or squirrels. They know. And exactly how do they know? Can they recognize the shrike immediately? Have they had bad experiences with shrikes? I have never seen one before.

I hope my nightmare, of little dead chickadee, mice and squirrel bodies hanging from the bird tree, does not come true.

Be careful what you wish for. I had wanted new birds to show up in the bird tree because the delightful chickadees, woodpeckers, mourning doves and red squirrels were becoming boring. I didn't know that a predatory songbird would show up.

Heads or Tails: Hoarfrost

On January 10th, I took photos of what I thought was wind blown ice formations on the Missisquoi River during the January thaw. I was wrong. What I saw is more interesting than that. It is surface hoar, a type of hoarfrost. You can see it in the above photo at the edges of the snow. In the photo below, it is in the foreground and looks like diamonds in the sun.

The Guide to Frost at SnowCrystals.com describes surface hoar:
The most common form of hoarfrost is called surface hoar. This consists of ice crystals that form on top of snow banks, usually overnight. The sparkles you see coming from a field of snow are often reflections off the facets of surface hoar crystals.

Surface hoar typically forms when a snowbank warms up during the day and is then cooled again overnight. The night air cools the surface of the snowbank more than the inside, so that water can evaporate from inside the snowbank and recrystalize on the surface. By morning the snowbank is covered with a layer of faceted ice crystals, and they can be quite large. These usually melt again once the sun comes up, so the best time to find surface hoar is early in the morning.

Surface hoar is a delight for our eyes.

Favorite Weekend Feeder Photos

Some photos are good; some are not. But these are my favorites from this weekend. I love the color, light and textures in the photo above. And the snowy face.

The pattern and motion in this photo make it a favorite.

If you view the full-size photo, you will see a crystal of ice in the woodpecker's beak.

Poor framing gave me, I think, a lot of interest here.

Chubby cheeks on Popeye, above, because he is hoarding; while the little squirrel digs for food.

They got the suet feeder off the tree. But only Popeye has the privelege of raiding it.

Ducking down into the snow tunnel.
Good timing.

The sweet little girl squirrel who seldom drops by for a visit.

Popeye is hoarding here. I wonder where he is stashing those cheek-fuls?

No comment needed.

Crafty Green Poet: Domesticated

On October 16, 2007, the geese began to fly south. It was, for me, a sad moment
This photo will open, full-sized, in a new window when clicked.

Crafty Green Poet: Domesticated:

Imprinted at birth by a human,
you never learnt to be what you are.
Flightless and petted, you enjoy comforts
of home and hearth,
insulated from the harsh
rules of nature that made you.

Winter air fills with honking
geese in joyful formation
high in unthinkable sky.
You look up, an ache in your bird’s brain
before waddling indoors
to be hand fed choice grain.

Later you puzzle over dreams
of endless blue and the steady beat of wings.

Book Review: The Geese of Beaver Bog by Bernd Heinrich

On April 22, 2007, I noticed a pair of nesting geese on the beaver ponds across the road. I was disappointed that they choose to nest here because I had been told they were aggressive and would make the ponds their own, chasing out other water fowl. That seemed to be confirmed when I saw that no mallards, wood ducks or mergansers nested here as they had before. I decided that I may as well take advantage of the presence of these birds and photograph their young when they hatched. These photos in this review were taken at 10x zoom.

I saw the three goslings soon after they hatched (but was never able to photograph them), but only for a day or two. The family quickly disappeared. I was concerned that they had been eaten by fox or coyote. Then in July, Wingnut and I went to Crystal Lake State Park to swim and there was my goose family. They had integrated into life at the park and were eating and pooping very well. The goslings were nearly as big as the parents.

The park staff was asking people to not feed the geese, but were ignored. A ranger told me that they had to clean fifty pounds of geese droppings a day and it was becoming tiresome. It was impossible to walk barefoot as we usually do. But the geese were pleasant, not aggressive, and enjoyable to observe, especially since I knew that they were "mine."

I have always wondered how the family got to Crystal Lake, a mile down the road and over at least one beaver dam and a huge falls at the Barton Waterworks. Why did they leave? Was the water at the beaver pond polluted in some way? Did the food supply in the ponds suddenly become scarce? Did the goslings walk or were they carried?

Heinrich wrote the amazingly personal and engaging book, The Geese of Beaver Bog, about his observations of a group of geese from 1997 - 2003. Heinrich is a professor of biology at the University of Vermont. I have read his book Mind of the Raven: Investigations and Adventures with Wolf-Birds (after observing ravens rolling in fresh snow) and have heard him talk about bees and other topics on Vermont Public Radio and National Public Radio.

This book is a wonderful resource for me. Heinrich's experiences with his geese and beaver pond are remarkably similar to mine. We are both in Vermont, so the plants and animals are the same, and the bird populations are similar. Reading this book was like sharing experiences with a friend who doesn't only know the pond, but understands the excitement and sadness that I see here. He would feel as badly as I did when a crow stole a young redwing blackbird. Or when I heard the killing of a deer one night. He would chuckle at the scene of the coyote meeting a beaver face to face on the ice.

Canadian geese are precocial: they are able to be independent after hatching. The goslings are not fed by the parents. They mimic the parent's behavior and quickly learn what wisdom they need to continue surviving. And the parents do take the goslings to other ponds and lakes after hatching. The beaver pond, with its mink, weasels, foxes and coyotes, is not safe for the youngsters. Heinrich's geese walked two miles through cow pastures to a new pond. Mine walked through the woods where there were many dangers from predators that could not be easily seen by the parents.

Geese will try to return to nest where they are born. So I will most likely be seeing geese here for some years to come. Geese pairs do not necessarily mate for life. They tend to be monogamous but life interferes with our plans: mates are killed, or are chased away. I learned about different groups of geese in North America ("races") and about their migration.

We tend to categorize animals as cute, smart, companions, pests, killers, unimportant — there is no end to how we judge which animals are worthy of living. But once we understand their complex behaviors and how they interact, we begin to identify with them and judge them worthy of living on earth with us. We are now concerned about the survival of mountain gorillas, wolves and other animals because of books and movies that personalize their lives. The Geese of Beaver Bog personalized the natural lives of geese for me. It demystified their behaviors, asked questions that I would like answered, and removed the "pest" stigma from them.

I believed geese were nuisances but now that I know them better, I will protect their right to survive in the beaver ponds. I won't be hoping that they never return. I will be re-reading this book in the spring so that I am prepared to better observe, and enjoy, the behaviors of the geese.
