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.

Age Range: 7 and up

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!

Bug of the Week: Poplar Petiole Gall Aphid

Have you ever wondered about the lumpy growths you see on leaves or stems?

cottonwood-petiole-gall-122

In this case the lumps are galls formed on the petioles of cottonwood leaves. This tree was covered with them.

cottonwood-petiole-gall-055

A lot of different insects and mites cause the plants to form galls, so I was eager to take an example home and see what was inside.

inside-cottowood-petiole-gall-060

Inside the gall I found numerous tiny insects covered with a waxy powder. Looking under a microscope, it became clear these were nymphs of the poplar petiole gall aphid, Pemphigus populitranversus.

The poplar petiole gall aphid (also known as the poplar petiolegall aphid in scientific literature) has a complex life cycle. The aphids overwinter as eggs on cottonwood twigs. When the leaves unfurl in the spring, the aphids hatch and begin to feed on the leaf petiole. The plant responds to the feeding by producing a localized growth, which becomes the gall. The aphid nymphs move within the gall and continue feeding.

When the aphids complete their life cycles, the galls split open and winged adults fly to plants of Brassica spp. There the aphids feed on the plants’ roots in the soil. In this stage, they have a second common name, which is “cabbage root aphid.” Eventually, at the end of the season, winged forms fly back to cottonwood trees to lay the overwintering eggs.

There are more to aphids than you might think. Many have similar complex life cycles, where they live on annual plant hosts in the summer and fly to woody, perennial hosts in the winter.

Have you ever spotted a gall on a plant? What kind?

Bug of the Week: Shield-backed Bug

After so many years of taking photographs of insects in the immediate area, it is still possible to find something new. Take for example this brown bug I found on the petals of a Mexican hat flower.

shield-bug-good-3-089

It turned out to be a shield-backed bug, family Scutelleridae.

shield-bug-face-on0095

Shield-backed bugs are relatives of stink bugs, and in fact they used to be in the same family. However, the scutellum (a part of the thorax) is much larger and covers the entire abdomen, including the wings. This structure resembles the hardened elytra of beetles and at first glance shield-backed bugs do look like beetles.

Like some of the more familiar stink bugs, shield-backed bugs feed on plants, particularly members of the family Asteraceae, to which Mexican hat plants belong. They have sucking mouthparts that they use to suck plant juices.

Also like stink bugs, shield-backed bugs have defensive glands that release a pungent scent if the insect is threatened or disturbed.

Discovering a whole new (to me) family of insects this week is quite exciting.

Have you seen any interesting insects this week?

Have you ever seen a shield-backed bug before?
