Birdology: 30 Hands-on Activities for Kids

For STEM Friday we’re going to the birds again with a new middle grade book, Birdology: 30 Activities and Observations for Exploring the World of Birds (Young Naturalists) by Monica Russo and photographs by Kevin Byron.

If you are already familiar with Chicago Review Press books for kids, you will recognize the format. Each section reveals information about a topic, such as feathers, and then provides suggestions for making observations and for appropriate hands-on activities to reinforce learning.

Birdology gives an introduction to many aspects of bird biology, such as their anatomy and special characteristics, where to look for them, what they eat, bird migratory behavior, etc. In the final section it explores common careers that involve working with birds.

The author is very careful to point out that it is illegal to collect or possess feathers, nests or eggs of wild birds. All the activity suggestions keep this important consideration in mind.

Educators will be interested in the Teacher’s Guide and Resources in the back matter. Monica Russo is an experienced teacher, which is evident because the Teacher’s Guide includes suggestions for how to accommodate a student who is afraid of birds. That is not something a beginning teacher is likely to have encountered.

Kevin Byron’s photographs are inspiring (see activity suggestion below). You almost wish more space had been devoted to them, although that might have left less room for the fabulous activities. See what I mean by checking out the barn swallow in flight on page 76.

Birdology is a must have book for beginning ornithologists, and basically any older child interested in science and nature. It would be wonderful paired with a citizen science project such as the Great Backyard Bird Count. Educators will also want a copy for ideas for quick projects that are appealing and well-designed, and that could work with multi-aged groups.

1. Anting by birds

Imagine you are watching some big black birds called crows. Suddenly one spies an ant mound, runs over to it and starts flopping around on it while ruffling its wings. Then it grabs some of the ants and starts thrusting them up into its feathers. What is wrong with this crow? Has it eaten some bad food? What is it doing?

In fact, the bird is using the ants’ defensive chemicals as a personal bug killer. Birders call this behavior “anting.”

Birds can be host to various itchy lice and mites. Scientists have long thought that by anting birds kill these parasites, but few are willing to do the experiments to prove it. However, one man actually took the lice off several birds he had observed anting and compared them to the lice on some birds that hadn’t anted. He found many of the lice from the anting birds died, but only a few from the non-anting birds.

When the birds actively pick up the ants and wipe their wings with them, it is called active anting. Other birds simply squat or lie on an anthill shaking their wings and tails, and stirring up the ants. This behavior is called passive anting.

You can see an example of passive anting in the following video (there is background music):

Doesn’t the behavior look odd at first?

When you are watching birds, be sure to keep your eye out for birds that are anting. Document your observations in a nature notebook, sketchbook, with photographs, or with video and then share them with others.

2. Bird Photography

Birds are often small and active, but with patience and experience, children can learn how to photograph birds.

Tips:

With any camera, start with larger birds that are easy to spot and are not likely to fly away. Water birds might be a good choice.

mallard-duck

Think about the background. Again, water birds make this easier because the water is generally uniform and gives good contrast.

heron background issuesSee how much easier it is to spot the mallard in the top photograph, where the heron gets lost in the second photograph?

heron-headNo pesky background in this photograph.

goose-head

Add interest to a photograph by concentrating on the head and eye of the bird. If  you study Kevin Byron’s photographs, you will see he does this.

Encourage your budding photographers to keep records of what kinds of birds they photograph, where and when the photograph was taken, what the birds were doing, etc.

Talk about the photographs, too. Compare the beak of the heron versus the goose. Do you know what each kind of bird eats? (Herons eat fish whereas geese graze on vegetation.) Who knows what else you might discover!

Insect Senses Activity Answers

Did you find the parts associated with insect senses from the previous post? Here are the labelled photographs to check.

Remember:

The following are public domain photographs taken by the USGS Bee Inventory and Monitoring Lab.  Name links will take you to the image in Flickr. Note:  For the squeamish, there are a few photographs of dead birds in their photostream (preserved specimens).

flower-fly-labelled-head

(Syrphid or flower fly, face view)

Flies have very interesting antennae. They are shorter and smaller than the antennae of many adult insects. Fly antenna also have a hair-like structure sticking out called the arista. A few kinds of flies, like mosquitoes, can “hear” when sound vibrations cause the arista to move.

The large eyes are made up of facets or ommatidia. Can you see the patterns they make in the eye?

They aren’t labelled, but did you spot the sensory hairs around the ocelli and those just above the antennae? They are longer and thicker than hairs in nearby regions. They might help the fly figure out how fast it is going.

bee-antenna-labelled-head

The antenna of this bee looks very different from that of the fly.

bee-labelled-head

The  Eucera dubitata bee has smaller compound eyes than the flower fly.

The mouthparts are complicated, consisting of tube-like tongue to suck nectar but also biting jaws to dig nests in the soil. The long, whitish hairs at the top of the mouthparts are sensory hairs. They might help position the tongue in flowers.

The other hairs on the bee’s body may not be not primarily sensory. They may help keep the bee warm and also to trap pollen. The bee scrapes the pollen off its hairs and bundles it into bee bread for the larvae to eat.

moth-labelled-headThe velvetbean moth has a thinner, more flexible moth for sucking nectar.

The antennae of male moths are often bushy and thicker than those of female moths.

Moths, which are active largely at night when it is cooler, have hairs on their body to help insulate them and keep them warmer.

Some moths also have tympana on the sides of their abdomen, which allows them to hear the echolocation signals of bats and avoid them.

Because there are so many different insects, there are of course many different insect senses. Please feel free to leave a question if you a curious about an insect we didn’t mention.

 

 

Insects Book and Insect Senses Activity for Kids

For STEM Friday we are sharing a Smithsonian Little Explorer nonfiction title:  Insects (Little Scientist) by Martha E. H. Rustad.

Young children are often fascinated by insects and this book will give them a good foundation in the basics of insect science. In addition to explaining metamorphosis and insect senses, it covers eight main insect groups from ants to grasshoppers. Each section is a two-page spread with bright color photographs throughout. Some of the photographs are edge to edge, giving a feeling that you are actually seeing the scene first hand.

In the back are suggestions for thinking more deeply about insects, as well as a glossary, book recommendations for further reading, and a portal to Internet Sites through FactHound.

Insects will thrill budding entomologists. It is also a useful resource for libraries and classrooms.

Let’s celebrate the book with an activity.

Related Activity:  Exploring Insect Senses

The following are public domain photographs taken by the USGS Bee Inventory and Monitoring Lab.  Name links will take you to the image in Flickr. Note:  For the squeamish, there are a few photographs of dead birds in their photostream (preserved specimens).

Animals need to be able to detect or sense information about their environments in order to survive.

1. Brainstorm about human senses.

Read a book about human senses, such as My Five Senses by Aliki (as seen read in this video).

Ask the children about what senses humans have and why they are important (like avoiding danger or finding safe food to eat).

(Extension:  You are likely to have been taught in school, as in the book, that humans have five senses. This is a simplification. Think about other senses we have, such as the ability to sense pain or the ability to tell which way is up in relation to gravity. We can also tell when our stomach is full via stretch receptors. Some scientists think we may have up to 20 senses!  How Stuff Works has more about this.)

2. Find out about insect senses.

Insects have senses as well, but theirs don’t look the same and work in different ways than ours do.

Human-vs-insect-senses-graphic

Can you believe that mosquitoes hear with their antennae and that crickets hear with tympana (strips of membrane stretched tight) found on their legs?

Many insects can detect chemical odors via their antennae, which work in a similar way to how our noses detect smells.

Look at the photographs below and try to find the parts the insects are using to see, hear, smell, taste and touch things around them.

Parts to look for:

  • Antennae
  • Compound Eyes
  • Ocelli (simple eyes)
  • Mouthparts

Bonus:  see if you can spot any special sensory hairs.

Once you have examined these insect photographs closely, go to the answer post for labelled photographs and more information.

Isn’t it amazing that even though they look and work in different ways, insects have senses just like we do?
