Every Friday we invite you and your homeschool students to learn about a different group of North American birds in your recommended bird guide (riverhouses.org/books). It’s a great way to add a few minutes of informal science, geography, natural history, and imagination to your homeschool schedule throughout the year.
This week’s birds are (once again) the Crows and Jays (pages 364–373). Usually we cover one or two different families each week, but we’ve spread the Crows and Jays out over two weeks: last week we looked at the Crows, and this week the Jays.
If you’re teaching younger children, the way to use these posts is just to treat your bird guide as a picture book and spend a few minutes each week looking at all the interesting birds they may see one day. With that, your little lesson is done.
If you have older students, one of your objectives should be to help them become fluent with a technical reference book that’s packed with dense information, the kind of book they will encounter in many different fields of study. Here again is the bird guide’s introduction to this week’s group, written in the customary telegraphic style:
“CROWS · JAYS — Family Corvidae. Harsh voice and aggressive manner draw attention to these large, often gregarious birds. Powerful, all-purpose bill efficiently handles a varied diet. Species: 126 World, 21 N.A. [North America]“
When you’re training your young naturalists, teach them to ask and answer from their bird guide some of the first questions any naturalist would ask about a new group. How many species? (126 worldwide.) Are there any near us? (21 species in North America, and the individual maps will give us more detail.) What are their distinctive features? (Loud, gregarious, varied diet, and so on.)
Pick a representative species or two to look at in detail each week and read the entry aloud, or have your students study it and then narrate it back to you, explaining all the information it contains. This week, for example, why not investigate a bird of the Rocky Mountains and the West: the Steller’s Jay (page 366).
All sorts of biological information is packed into the brief species descriptions in your bird guide — can your students tease it out? How big is the Steller’s Jay? (11½ inches long.) What is its scientific name? (Cyanocitta stelleri.) Will you be able to find this species where you live? At what times of year and in what habitat? (Study the range map and range description carefully to answer those questions, and see the book’s back flap for a map key.) Do the males and females look alike? The adults and juveniles? What song or call does this species make? How can you distinguish it from similar species? (The text and illustrations should answer all these questions.)
The two most common jays in the United States are the Steller’s Jay of the West and the Blue Jay of the East. In fact, these two species sometimes hybridize (cross-breed) in the eastern Rockies where their ranges overlap. As a good comparative exercise, invite your students to look also at the Blue Jay and see how these two species differ.
The Steller’s Jay is obviously darker, but note that both species are almost exactly the same size and shape, with similar behavior, matching crests, and even similar black and blue barring on the wings. They are what biologists call “sister species” — one another’s closest evolutionary relatives.
You can do little ten-minute lessons of this kind with any of the species in your bird guide that catch your interest. Pick a species that is near you, or one that looks striking, or one that has a strange name, and explore. For an additional species this week, why not take a look at the Black-billed Magpie (page 370), a large and long-tailed jay-like bird that’s found throughout much of the West. (Our Black-billed Magpie is very similar to the Eurasian Magpie of the eastern hemisphere, a bird well known in folklore and literature.)
In all these Friday Bird Families posts, our aim is not to present a specific set of facts to memorize. We hope instead to provide examples and starting points that you and your students can branch away from in many different directions. We also hope to show how you can help your students develop the kind of careful skills in reading, observation, and interpretation that they will need in all their future academic work.
What ornithological observations and naturalistical notes have you been making in your homeschool this Leo Term? 😊
❡ Homeschool birds: We think bird study is one of the best subjects you can take up in a homeschool environment. It’s suitable for all ages, it can be made as elementary or as advanced as you wish, and birds can be found just about anywhere at any season of the year. Why not track your own homeschool bird observations on the free eBird website sponsored by Cornell University. It’s a great way to learn more about what’s in your local area and about how bird populations change from season to season. 🐦
❡ Vade mecum: The front matter in your bird guide (riverhouses.org/books) (pages 6–13) explains a little bit about basic bird biology and about some of the technical terminology used throughout the book — why not have your students study it as a special project. Have them note particularly the diagrams showing the parts of a bird (pages 10–11) so they’ll be able to tell primaries from secondaries and flanks from lores. 🦉
❡ Words for birds: You may not think of your homeschool dictionary (riverhouses.org/books) as a nature reference, but a comprehensive dictionary will define and explain many of the standard scientific terms you will encounter in biology and natural history, although it will not generally contain the proper names of species or other taxonomic groups that aren’t part of ordinary English. (In other words, you’ll find “flamingo” but not Phoenicopterus, the flamingo genus.) One of the most important things students should be taught to look for in the dictionary is the information on word origins: knowing the roots of scientific terms makes it much easier to understand them and remember their meaning. 📖
❡ Come, here’s the map: Natural history and geography are deeply interconnected. One of the first questions you should teach your students to ask about any kind of animal or plant is, “What is its range? Where (in the world) does it occur?” Our recommended homeschool reference library (riverhouses.org/books) includes an excellent world atlas that will help your students appreciate many aspects of biogeography, the science of the geographical distribution of living things. 🌎
❡ Nature notes: This is one of our regular Friday Bird Families posts for homeschool naturalists. Print your own copy of our River Houses Calendar of American Birds and follow along with us! You can also add your name to our free weekly mailing list (riverhouses.org/newsletter) to get great homeschool teaching ideas delivered right to your mailbox all through the year. 🐦 🦉 🦆 🦃 🦅
