How do animals communicate without using words? In this Nature Adventures Homeschool Program, kids will explore the many ways animals use sounds, calls, and other signals to communicate. From bird songs and frog calls to warning sounds and animal “conversations,” we’ll discover what animals are saying and why their voices are important. Through hands-on activities, games, and plenty of listening, participants will put their animal communication skills to the test.

Christmas Bird Count

Christmas Bird Count
All Over County
December 17, 2026
For over 125 years, the Audubon Society has held Christmas Bird Counts across the United States. Data gathered from these counts is used to understand bird populations. During the Christmas Bird Count, groups are assigned an area within a 15-mile radius and record as many different bird species as possible. The species and numbers are then compiled, sent to the Audubon Society, and documented. The count must take place around Christmas, and groups must pick a specific 24-hour period to record birds. The date we have selected is December 17. We have multiple bird experts and have divided the quadrant into sections. There are several ways to participate in a birding day. 1. If you are an expert, you can help lead a group. 2. Even if you don’t know birds, you can join an expert and learn about birds along the way. 3. If you have bird feeders at your home, you can watch and record the birds that come to your feeders. You do not have to dedicate 24 hours. You can give as much time as you want. If you are interested in joining us for the bird count on December 17, please get in touch with Emma Bruck at 641-752-5490 or ebruck@marshallcountyia.gov by December 11 at 4:00 p.m. The map below shows the regions we will cover. This includes the towns of Marshalltown, Albion, Green Mountain, and Laurel.

How do animals survive when winter brings freezing temperatures, snow, and limited food? Kids will discover the amazing adaptations animals use to make it through the coldest months of the year. We’ll explore how feathers, thick fur, body fat, and other physical adaptations help animals stay warm, as well as different ways animals overwinter, including hibernation, migration, and remaining active throughout the season. Through hands-on activities and exploration, we’ll uncover the strategies that help animals survive and even thrive in the cold.
