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 Wood-Warblers (pages 452–485), the little jewels of the American forests. Usually we cover one or two different families each week, but we’re spreading the Wood-Warblers out over two weeks because there are so many of them: about 109 in the western hemisphere (the only place they occur) and 57 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 again is the bird guide’s introduction to this week’s group, written in the customary telegraphic style:
“WOOD-WARBLERS — Family Parulidae. About half of the many species in this colorful New World family occur in N.A. [North America] Most are highly migratory; a few reach central S.A. [South America] Species: 109 World, 57 N.A.“
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? (109 worldwide.) Are there any near us? (57 species in North America, and the individual maps will give us more detail.) What are their distinctive features? (Small, colorful, highly migratory, 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, why not investigate the Common Yellowthroat (page 464), a little masked warbler with a loud voice.
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 Common Yellowthroat? (5 inches long.) What is its scientific name? (Geothlypis trichas.) 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.)
Many warbler species live high up in the tree canopy, but Yellowthroats typically prefer low brush and thickets, often near water. Their loud and repetitive call — wichity wichity wichity — is often heard long before the bird is seen. The males have the characteristic black mask that gives them away; the females are much plainer and can be difficult to distinguish from other female warblers, especially in the fall.
For a second species in the Wood-Warbler family this week, take a look at the Yellow-rumped Warbler (page 472), another species that is common across the entire United States. Yellow-rumps are highly migratory like most warblers, but they are one of the few species that will occasionally overwinter in northern areas if they have a good supply of food available — bayberries are one favorite in the northeast, as is suet at a birdfeeder.
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 is near you, or that looks striking, or that has a strange name, and explore. For a third warbler this week, instead of a common species why not take a look at one of the rarest birds in North America: Kirtland’s Warbler (page 478). Kirtland’s Warblers nest only in young stands of Jack Pine in northern Michigan, and nowhere else in the world. Current estimates put the total population at about 5,000 individuals.
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 Hercules 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. 🌎
