Explore Outdoors ~ Look closer
Even when drying out, rosehips add a splash of color to the landscape: bright red against the white snow. But when you look closer you discover real treasure. The stem has thorns, but also hairs. As the hip ages, it becomes wrinkled. And sometimes, when you look even closer, you find tiny treasures. In this case it's snowflakes stacking on each other.
Look closer at the winter weeds and plants in your neighborhood. What do you notice?

Explore Outdoors ~ Make a bird feeder
Here’s what you need:
- A plastic water bottle, soda bottle, or other liquid - with lid
- sharp scissors or a craft knife
- 2 wooden spoons
- wire, string, or twine for hanging
- optional: small eye-screw
- bird seed
Here's what you do:
1. Take the label off the bottle. Then wash it and let it dry.
2. On the side of the bottle, not too far from the bottom, cut a semicircle arch (a bit bigger than an inch) but leave the plastic uncut at the bottom of the arch. Pull the flap out and down.
3. Push the handle of one wooden spoon through this hole. Mark where the handle hits the opposite side of the bottle. Cut an X at that mark and push the spoon handle through. It should fit snuggly. Turn the spoon so the scoop is facing up. This is a perch where birds will find seeds.
4. Turn the bottle so that when you look at it, the wooden spoon is going from left to right. Half way up the bottle, cut another semicircle arch. Push the handle of the second wooden spin through this hole – it should cross the first spoon at a right angle (doesn’t have to be perfect).
5. Mark where the handle hits the opposite side of the bottle. Cut an X at that mark and push the spoon handle through. Then turn the spoon so the scoop is facing up.
6. Use a funnel, or roll a piece of paper to make a funnel, to fill the bottle with bird seed. Some seed should spill out of the semicircle arches into the spoons.
7. Put on the lid. Then tie wire or string around the top of the bottle to hang it. Option: screw an eye-screw into the lid and then put wire or string through that to hang the feeder.
8. Hang your feeder from a tree or clothesline or somewhere that birds will find it and you can watch it.
If you make two feeders, you can do an experiment. Paint the bottom part of one feeder (below the bottom spoon perch) red and the other green. Paint the lids matching colors, too. Then see if birds like one color better.
Here’s a video that shows how to make a feeder, and here are some pictures of a bottle feeder. Check out these “Make your own feeder” activities from Cornell Lab of Ornithology. At the end are some fun ways to recycle yogurt containers into bird feeders.

Accidental Bird Science
A week or so ago, my friend and romance novelist Carol Henry shared an observation. She hung a number of feeders around her house and noticed that the red feeders ran out of seeds before the others.
Do birds like the red feeder more than the green one? she asked her Facebook friends.
So she hung a green feeder outside her office window right next to the red one. And the red feeder emptied faster. “Just to be sure, we traded places and put the red feeder where the green one was, and the green where the red one was.” She refilled both feeders with seeds and the same thing happened: the red feeder emptied much, much quicker. Then, she replaced the green feeder with a red feeder and refilled them with seeds. This time both feeders emptied within the same time frame.
My friend is not a professional scientist, but she is curious. To me, that curiosity is the core of being a scientist: question-asking, doing an experiment, noting observations, sharing information with others, and encouraging them to explore those same questions. Carol isn’t the first person to ask whether birds prefer different feeder colors. A few years back, the Royal Society for the Protection of Birds asked a similar question: Do different colored feeders attract different birds? They found that some birds preferred silver feeders, others preferred blue, and still others would rather visit red feeders. And that this color preference changed with the season.
But back to my friend’s question: do the birds in her yard prefer the red feeders over the green feeders? I asked my ornithologist friend, Tom Sherry, what he thought. Tom is a Professor in the Dept. of Ecology and Evolutionary Biology at Tulane University and he noted that, while hummingbirds are definitely attracted to red colors, he had not heard about color preference for seed feeders.
“I’d want to know exactly how close the feeders are to each other,” he said, “because slight differences in position, such as how windy and distance from vegetation cover, can make a huge difference. Even slight differences in seed mixtures could matter, or whether birds have equal access to seeds, or perch, at both feeders. You want to be sure it’s just the color, and not some “hidden” variable that’s causing the difference.”
Needless to say, Carol’s question generated a bit of discussion between a few of us who feed the hardy feathered souls that overwinter in upstate New York. I’ve got a green feeder, but now I’m wondering whether I ought to head to the hardware store and buy a red feeder?
Drop by on Wednesday to find out how to recycle a plastic bottle into a bird feeder so you can do your own backyard bird science.
