For STEM Friday we are featuring the new middle grade nonfiction book Crow Smarts: Inside the Brain of the World’s Brightest Bird by Pamela S. Turner and photographs by Andy Comins, which chronicles Dr. Gavin Hunt’s intriguing research into tool use and learning by New Caledonian crows.
Why New Caledonian crows? It turns out they have a lot going for them. They are pretty smart. Not only can they use sticks as tools to pry their food- in this case large beetle larvae – out of wood, but also they can fashion new tools by shaping and modifying twigs and stems. As more sophisticated experiments have shown, they have a remarkable ability to solve problems (see some of the videos below). They also have bigger eyes than other species of crows and their eyes are closer to the front of their head, which means they have better depth perception.
Although the special crows are fascinating enough, author Pamela Turner’s discussion of Dr. Hunt’s research is written with just the right touch of humor to keep young readers fully engaged. For example, she notes one of the crows is named “Crow we never got around to naming.” Many of her observations are highly entertaining.
Andy Comins’s amazing birds-eye-view photographs (see the one on the cover above) help us see the crows as individuals. It isn’t easy to photograph active birds in the wild, and he makes us feel like we are right there studying the birds, too.
Whether you have read all of books in the Scientists in the Field series or none of them, you are going to want to pick up this one. Perfect for anyone interested in learning, animal behavior, birds, tool use, or science in general.
Below are some bird science activity suggestions that could be used to accompany the book.
Activity Suggestion 1: Building a Bird Blind
Dr. Hunt knows he might change the crows’ natural behavior if they knew he was watching them, so he uses shelter to observe the crows unnoticed. The camouflaged shelter is called a “hide” or a “blind.” In the field he uses a portable tent as a blind (photograph page 12 of the book), but children can design and build their own bird blind.
Gather:
- Sheet, large piece of cardboard, or cardboard box
- Twine, cord, rope or painter’s tape
- Twist ties
- Paints in camouflage colors (optional)
- Paint brushes (optional)
- Scissors (craft knife for adults only)
- Markers
- Birdseed (optional)
- Birdwatching supplies:
- Notebook
- Pens and pencils
- Field guide for identifying birds
- Binoculars (optional)
- Clock or watch
- Find a location to set up the blind, either indoors or out depending on the weather and other factors. If you already have a bird feeder near a window, setting up a blind inside the window would be ideal. Outside, look for areas where birds are active on a regular basis, such as in shrubs, trees, or near a food source.
- If you choose to, paint the sheet or cardboard with camouflage colors (investigate what colors birds can see and plan accordingly). Allow to dry.
- If you are setting up inside, cover the window with a cardboard box with the bottom facing out or tape up the sheet with painter’s tape. Outside, tie the twine or cord between supports such as poles, fences or trees. Drape the sheet over the cord, or lean the cardboard against the cord, and fasten with clothespins or twist ties.
- Have the children stand or sit in a comfortable position. Using the markers, mark where the eye holes should go. The holes should be a small as possible so they aren’t obvious to the birds, but large enough to allow for comfortable viewing. Cut out the holes.
- If you choose, sprinkle some birdseed in the viewing area or feed the birds to attract them (optional). Sit or stand quietly behind the blind and view the birds. Younger children may simply draw a picture of a bird they see. Older children may want to keep a more detailed record of what kinds of birds visit, what time of day, how long they stay, which direction they go, etc.
- Suggestion for experiment:Â Do blinds really work? Design an experiment to test whether birds behave differently when observed through a blind versus when viewed from similar distances and circumstances without a blind.
Activity Suggestion 2:Â Watch some videos/bird cams of the behavior of crows and other birds.
Even if you don’t have the opportunity to observe bird behavior in nature, learn more about birds by watching videos like the one below and/or by visiting bird cams online (The Lab of Ornithology has a number of ongoing bird cams to get you started.)
Check Pamela S. Turner’s website for many more videos of crows doing funny and amazing things.
