For April Fools’ Day I couldn’t resist a little quiz about the amazing talents of pigeons.
Are any of these statements true?
- During World War II electronic missile guidance systems were not yet reliable so the NDRC funded a project to use trained pigeons to guide missiles.
- Pigeons can hear distant thunderstorms and far-away volcanoes that we cannot hear.
- Pigeon nests are cemented with pigeon poop.
- Google uses “pigeon clusters” to enhance its search technology.
- Some pigeons can fly 600 miles a day.
- Pigeons can rescue people capsized at sea.

And now for something completely different (not about peregrines).
I found this understory tree “blooming” in many places along the North Shore bike trail at Moraine State Park on Sunday. It drew my attention because of its long, yellow catkins.
Do you know what it is? Here are some hints:
- The plant grows in clumps like a shrub.
- The clumps are on average about 10 feet tall.
- Its long yellow catkins indicate it’s in the birch family.
- Many of the catkins sprout alone instead of in bunches.
- The catkins are as long as — or longer — than my fingers.
- The leaf buds are alternate on the branches.
- The bark is smooth and speckled.

I can usually identify this plant in a heartbeat, but I was stumped when I saw this photograph. Maybe you will be too, so I’ve made it a quiz.
Here are some clues:
- The plant is a perennial native of Asia.
- It’s invasive in North America wherever it’s found.
- The stems are hollow and stand over 10 feet tall, persisting through the winter.
- The plant spreads by wind-borne seeds and rhizomes.
- The rhizomes are particularly difficult to eradicate and result in dense stands of this plant.
- It was originally brought here as an ornamental because it’s flowers are arranged in pretty cream-colored sprays above the stems. (This is the flower stalk in winter.)
- The young stems are edible and taste like rhubarb but Americans don’t like it well enough it to reduce its population by harvesting.

If you recognize this flower in August it also looks familiar at this time of year.
Tall or Canada Goldenrod is a native perennial that maintains its shape, even in winter. It still stands two to six feet tall, it still carries alternate leaves on a rough stem and it still holds up a plume-like spire where the flowers used to be. The spire was a dense cluster of golden flowers in August. Now it’s a dense cluster of seeds.
You’ll find goldenrod in open areas, often in large patches because the rhizomes (roots) spread underground.
Goldenrod species are notoriously difficult to identify. I listed two names for this plant because I’m not sure which one it is. It might be Tall Goldenrod, maybe Canada Goldenrod, maybe something else. It doesn’t matter. My excuse is that the plant isn’t in good condition.
And here’s a Quiz: Can you identify the tall plant on the left edge of this photo? I discussed it in an earlier Winter Weeds blog. Remember?
p.s. Today is Groundhog Day. Check here for news from Punxsutawney Phil. Rumor has it he did not see his shadow so Spring is near.

Whose curly-headed baby bird is this?
Here are some hints:
- He is on an island in the Pacific Ocean.
- His species is critically endangered because 99.9% of them nest this island only.
- His parents built no nest. His mother laid his egg on bare ground.
- It took two months for this baby to hatch, then six more months before he can fly.
- His parents feed him regurgitated oil derived from fish, squid and crustaceans.
- Sometimes he must wait a long time between feedings because his parents travel 6 to 60 miles to find food.
- He is one of 22 species in this family of birds (species count from BirdLife International).
- A famous poem tells us it’s very bad luck to kill this type of bird.
Do you know who he is? Leave a comment with your answer.
UPDATE at 9:45am: Most of you guessed the family of birds correctly. Can any of you guess the exact species? Hint: This is a tropical island.

Quick! Name an animal — not a bird — that can fly like this. Here are some clues.
- This animal doesn’t flap, but it does fly.
- It has better lift and less drag than many insects.
- It’s lift ability is the same as for hawks and wood ducks.
- The longest time it’s been recorded aloft is 45 seconds.
- It can travel as much as 1,300 feet in one flight. That’s more than 4 football fields!
- And, with the help of the wind, it can speed along at 43 miles per hour.

Today’s quiz is something I’ve been wondering about.
In spring, summer and fall rabbits were everywhere and easy to find. Now that the ground is snow covered, I haven’t seen any and I’ve found only one set of tracks in all my travels.
So where did the rabbits go? Are they hiding? Or sleeping?
My reference guides make it sound like the winter life of rabbits is barely different from summer’s except that they change their diet from leaves to twigs. I find it hard to believe that that’s the only difference.
If you know what rabbits do and where they go in the winter, please leave a comment to let me know.
I’m sure many of us will learn from it!

Guess what bird this is.

Now that the trees are bare I’m sure you’ve noticed large ball-shaped nests in the bigger trees.
Do you know whose nests these are?
Here’s some information that may help you answer the question:
- The nests are round and about the size of a beachball.
- They’re as much as 70 feet above the ground. Click on the nest photo to see what they look like from a distance.
- The outer layer is often covered in leaves.
- The inside is lined with moss, grasses, shredded bark, etc.
- The opening of this nest is not on top. Instead it faces the tree trunk. Can you guess where the opening is on a nest that has no trunk near it?
- Believe it or not, this nest is water resistant.
So, whose nest is this? Leave a comment with your answer.

Today’s quiz should be easy for anyone who lives in Pennsylvania.
I found this damaged hemlock in Moraine State Park last weekend.
- What happened to this tree?
- Who did this? And why?
- Does this happen to trees of any size?
- Does this normally happen to hemlocks?
- Hardest question: What significance does tomorrow, November 29, have for this particular tree?
