Discovering Birds with South Knoxville Elementary Students!

On November 7th, Discover Birds volunteers paid a visit to after-school students at the South Knoxville Elementary School to present the Discover Birds program and help students find birds that live around their school yard.

Learning to use binoculars to get better looks at the birds, was the first activity students experienced before going outside for their bird walks on the sidewalks of the campus.
Students learned to adjust the binocular focus for their vision, to focus on stationary objects and to bring the binoculars up to their eyes while still looking at the object or bird in order to get the binoculars on the object.  
Jerry Ledbetter suggests students focus on the words on a sign in the lobby for practice.
Below, Lynn Davis talks with students about using their ears to listen for birds.  The presence of birds is often noted first with our ears because they make many vocalizations while foraging and flocking.  Being quiet increases the chances of hearing a bird and reduces the chances of scaring the bird away.  
Once outside, the students watched for movement and listened for the sounds birds make while feeding or flying.  There were several types of berry producing shrubs near the school grounds that attracted birds.

Above, Jerry Ledbetter helps a student get his binoculars on a bird.  Once the bird is in view, students took note of the bird's characteristics.  What markings are on the face?  What is the bird's overall size and shape, the overall color?  What color is the beak?  
Look closely to find the bird in the image above.  Sometimes leaves and limbs get in the way of seeing the entire bird at once, but we can often see enough to identify the species.  A small flock of Cedar Waxwings was feeding on the ripe, red berries found in this honeysuckle shrub.  Normally, the waxy tips of a Cedar Waxwing's tail are yellow, but if the bird eats many of these honeysuckle berries while the feathers are developing, the red content in the berries turns the tail tips orange or reddish-orange!
A female Downy Woodpecker, above, was another big hit and easy to see as she foraged on insects on a tree's bare limbs and trunk.  
Marikay Waldvogel and Lynn Davis pass out Tennessee Birds--Naturalists Pocket Guides, to help students identify the birds they see.  Students also used the guides to identify some of the birds they have seen in their yards at home.

Before returning to the school building to rotate into a different part of the program, third grade students pause to have a group photo made, below.  The Discover Birds Program was presented in three parts--a guided bird walk with binoculars, a show-and-tell experience with bird-related objects students can view up close, and a slide presentation about birds.  Approximately 66 energetic students participated in the program.
Below, Billie Cantwell talks with students about hummingbirds and their small size and long migration.  By placing a tiny band on a hummingbird's leg, biologists are learning about hummingbird migration patterns and their life span.
Billie, who organizes the Discover Birds program visits, has had a male Rufous Hummingbird wintering in her yard in Knoxville for the past four years.  She knows it is the same bird each year because of the unique number it wears on its leg band.
Above, Billie talks with students about the unique characteristics of birds that make them different from other animals.
Volunteer, Doug Schneeberger, talks with students about the characteristics of a bird's feathers, including the overlapping barbs at the end of each filament that act like a zipper to hold the feather filaments in place.
A holly full of red berries at the corner of the sidewalk is an attraction for several birds species. A Song Sparrow foraged on the ground underneath for seeds and insects.
A Northern Mockingbird perches on a high holly limb to over look his territory.  He didn't seem to mind the movement of the students or the sound of their voices.  After all, he lives around the school grounds all the time.  Everyone tried to get the mockingbird in focus through their binoculars.

Below, Marikay Waldvogel recalls the bird species seen with a student.
The birds seen during our bird walks included:  Northern Mockingbird, Carolina Chickadee, Song Sparrow, Common Grackle, Canada Goose, European Starling, Cedar Waxwing, Downy Woodpecker, American Robin, Mourning Dove and American Crow.
Each of the students received a Discover Birds Activity Book that they could take home with them to continue learning about birds.  The books were contributed by the Knoxville Chapter of the Tennessee Ornithological Society.

A big thank you to South Knoxville Elementary School for inviting the Discover Birds Program to visit the school.  Appreciation, also, to Discover Birds volunteers Jerry Ledbetter, Marikay Waldvogel, Lynn Davis, Billie Cantwell, Doug Schneeberger and Vickie Henderson for bringing the program to the school!

Discovering Birds with Blount County Home Education Association!

In the midst of a long string of gray, rainy days, the Discover Birds Program and Blount County Home Education Association had a beautiful, sunny day on October 17 at Ijams Nature Center!
Approximately 46 children and parent-teachers, for a total of 66, enjoyed the program lead by volunteers from the Knoxville Chapter of the Tennessee Ornithological Society (KTOS).
Before beginning their bird walks, students were given binoculars and Tom Howe (above) explains how to "get your binoculars on a bird".  The secret--keep your eyes on the bird and raise your binoculars to your eyes.
Students practiced adjusting the focus of the binoculars and looking at stationary objects before trying to focus on a bird that likely will be moving.

The large group was divided into three sections, with each group rotating through the three parts of the program:  a slide-show presentation about birds, a "show-and-tell" treasure chest with bird related items for close-up viewing and discussion, and a guided bird walk using binoculars and a scope.

The first bird walk group was divided into two groups, one walking in an open area with wooded edges, the other heading for a trail in the woods.  Each habitat offers an opportunity to see and hear different birds.
Throughout the wooded walk, we heard Carolina Wrens, the bird that sings "tea-kettle, tea-kettle, tea-kettle" and likes to hang around our homes and gardens.  They build multiple nests, sometimes in mailboxes and old shoes!  We heard call notes, scolding and their songs as wrens answered territorial songs and warned of the group's presence.
We couldn't see the wrens because they are so small and well camouflaged.  Birding-by-ear is another fun way to discover birds as you walk!

Above, binoculars are aimed at a Cape May Warbler that landed close.  While watching a Carolina Chickadee forage on a tree trunk, the group also spotted a nest of curious baby squirrels.

While the above group was on their bird walk, another group enjoyed the bird slide show.  Below, Billie Cantwell talks with students while waiting for everyone to get seated.

The slides show birds of all sizes and shapes with many different kinds of beaks and feet.  Everyone was familiar with the Ruby-throated Hummingbird.  In response to a student's observation, Billie explains a way to help a trapped hummingbird find its way out of a building.
Hummingbirds must have nectar to sustain their high energy and will quickly become exhausted if trapped.  Billie suggested opening the door to the building or garage and setting a table with a nectar feeder near the opening.  Hummingbirds natural fly upward when trapped and can't find the exit. The hummingbird will be attracted to the nectar near the outdoors and find its way out.
A group of young students listen to Doug during their show-and-tell session.
Above and below, the children feel the weight of a nest made with sticks and mud.

Finding birds in the afternoon, on a sunny and windy day is not easy.  Birds are often quiet and resting after a busy morning of feeding.  The group watched a Blue Jay fly from one wooded edge to another and then got a special treat.  Three immature bald eagles glided overhead.
Everyone tried to get the eagles into their binoculars--not easy when a bird is in flight.
Below, Chris shows students the light and dark patterns and "feather fingers" that help in identifying a bald eagle in flight.

Soon after the eagles flew by, a Red-tailed Hawk was spotted.  Everyone was excited about seeing these large soaring birds that were catching thermals or the warm, rising air currents that enable them to soar without flapping their wings.
A group of students, below, discuss what makes birds special and different from other animals.  
Doug challenges their thinking with questions about what muscle groups enable birds to flap their wings.

A large sternum and well-developed breast muscles help give birds their strength in flight.

A student below, examines the contents of an owl pellet.
Doug asks, "from which end does the bird expel the pellet?" Eyes brighten and one student answers, "the bottom end", but that isn't correct.  Pellets are expelled through the mouth as regurgitated balls of undigestible prey parts.  Below, owl pellets are shown with undigested prey skulls, bones and hair,
Each group of students received a special presentation from Sammi Stoklosa and met a non-releaseable Eastern Screech Owl that lives at Ijams Nature Center.
The owl was hit by a car and lost one eye.  Sammi explained that this often happens because people throw food out of their cars which attracts mice or other rodents.  The owl is attracted to the prey as a food source.
Owls are night hunters and rely heavily on their hearing.  They also have specially adapted flight feathers that are silent in flight.

A special thank you to Ijams Nature Center for allowing us to use their educational trails and facility. And a big thanks to the Blount Home Education Association and Billie Cantwell for arranging this program.  A special thanks also to KTOS Discover Birds volunteers:  Doug Schneeberger, Chris Welsh, Tom Howe, Tony King, Sammi Stoklosa, Susie Kaplar, Robin Barrow, Billie Cantwell and Vickie Henderson.
