Call of the Wild (WSJCANC)

TopicHabitat and Management - Population Surveys
Wildlife - General
Summary
Participants will hear wild animal sounds and learn why animals call and vocalize. They will learn about calling devices and how wildlife biologists use them to monitor populations and how hunters use them to attract game.

Objectives
  • Identify animal calls and calling devices.
  • Learn how animals communicate with sound.

Background

Wild animals communicate with sound and have vocalizations for different reasons. Some animals use them to locate a mate, defend territory, alert others to predators, hunt or simply let other animals know where they are.

Procedure
  1. Introduce yourself and the CANC. Explain that it is owned and operated by AGFC and showcases the agency’s mission. Also tell how Amendment 75 of 1996 funds paid for the facility and allow free admission.
  2. Discuss the ways wild animals communicate and ask for examples. Tell them wild animals mix vocal calls, scents and signals to communicate.
  3. Show animal photos and use a mechanical sampling of vocalizations for each species shown.
  4. Discuss how animal sounds have different meanings and demonstrate assorted hand-held calls.
  5. Outline population monitoring within scientific wildlife management. Explain how wildlife biologists use gobble surveys (eastern wild turkey) and whistle counts (bobwhite quail) to collect data and gauge wildlife populations. Show charts and graphs compiled from these counts. Note that wildlife biologists compare wildlife populations with the carrying capacity of the land to determine management strategies.
Modifications

Use the gobble survey and whistle count to create math lessons.

Review
  • In addition to vocalizations, what are some other ways animals communicate? (scent, posturing or signaling)
  • What are additional ways wildlife biologists might monitor animal populations? (electronic tagging, trapping, visual counts, hunter surveys)

Glossary

Arkansas Game and Fish Commission – the state agency responsible for managing fish and wildlife

 

Bark – a sharp, chattering call by squirrels to clear an area of predators and alert other squirrels of danger

 

Bleat – a soft social call made by white-tailed deer does and fawns

 

Bugle – the “scream” sound made by bull elks to assemble cows or to warn other bulls

 

Carrying capacity – the amount of wildlife an area of land can sustain which varies with the amount of food, water and shelter available

 

Gobble survey – annual population count of wild turkeys made by wildlife biologists by listening for turkey gobbles in designated areas; estimates turkey populations in the spring

 

Grunt – a low-pitched, exhalation sound made by a white-tailed buck deer to a doe during the rut (breeding season)

 

Snort – a loud “whoosh” sound made by white-tailed deer by exhaling air through their nostrils when alarmed; often made in succession; used to locate an unseen predator they have heard or smelled or to alert other deer of danger

 

Population survey – a sampling method wildlife biologists use to estimate the number of a species in an area; can be done in many ways including vocalization counts, harvest data from hunting season, trap counts, visual counts

 

Vocalization – a sound made by a wild animal to communicate with other animals; have various meanings including social, mating, alarm, aggression

 

Whistle count – annual population count of northern bobwhite quail made by wildlife biologists by listening for the “bob white” whistle in designated areas; estimates quail populations in the spring

 

Wildlife biologist – a scientist who studies and manages wild animals
