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 school-year’s tour began last week with an introduction to your bird guide.)
This week’s birds are the Ducks, Geese, and Swans (pages 14–53). Usually we’ll cover one or two different families each week, but we’re spreading the Ducks, Geese, and Swans out over two weeks because there are so many of them: about 160 around the world and 66 in North America.
If you’re teaching younger children, the way to use these weekly overviews is just to treat your bird guide as a picture book and spend a few minutes every Friday 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 information, the kind of book they will encounter in many different fields of study. Here is the bird guide’s introduction to this week’s group, written in the customary telegraphic style:
“DUCKS · GEESE · SWANS — Family Anatidae. Web-footed, gregarious birds, ranging from small ducks to swans. Largely aquatic, but geese, swans, and some ‘puddle ducks’ also graze on land. Species: 160 World, 66 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? (160 worldwide.) Are there any near us? (66 species in North America, and the individual maps will give us more detail.) What are their distinctive features? (Web-footed, varying in size, mostly aquatic, and as you can see from scanning the pictures, most have fairly plump bodies, short legs, and long necks.) (And “gregarious” is certainly a wonderful word — be sure to send someone to your homeschool dictionary to look that one up!) 🔎
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 one of the most familiar of all North American birds: the Canada Goose (page 20).
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 Canada Goose? (30–43 inches long — quite variable!) What is its scientific name? (Branta canadensis.) 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? (Honk-a-lonk.😊) How can you distinguish it from similar species? (The text and illustrations should answer all these questions.)
Like many other geese, Canada Geese are famous for their large “vees” — migratory flight formations — surely one of the most magnificent sights in the natural world. (Both of the above photos happen to be my own.)
And of course everyone loves Canada Geese because they honk. 🔊
You can do little ten-minute lessons of this kind with any of the species in your bird guide that catch your interest. Pick one that lives near you, or that looks striking, or that has a strange name, and explore. Take a look at the four species of Swans on page 22, for example — can your students figure out how they differ from each other? (They are very tricky to identify — you’re teaching your students to pay attention to fine details here.) Our fall term in the River Houses, just getting underway, is Cygnus Term. Where might that name come from? 🦢
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 will you be making in your homeschool this Cygnus 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, it can be made solitary or social, 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. 🌎
❡ State birds: One member of this week’s bird family is a United States state bird: the Hawaiian Goose or Nene (Branta sandvicensis). Unfortunately, you won’t find the Hawaiian Goose in your North American bird guide, because Hawaii, while part of the United States, is not part of North America! But don’t despair: the Hawaiian Goose profile on the eBird website will help you learn all about it. 🇺🇸
❡ 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!
