What is the Amos Butler Audubon Society Birdathon?
Since 1987 the ABAS Birdathon has been on a mission to promote the enjoyment and stewardship of the birds of Central Indiana. Birdathon is the organization’s premier fundraising event. A notice is sent out in early January requesting grant submissions for conservation and education projects. The grant requests which are determined to be the best candidates for fulfilling our mission are selected for funding. Each year teams of avid birdwatchers conduct a “Big Day” event in the spring to locate as many species as possible in a 24-hour period to raise Birdathon funds. We began with just one team, but now over a dozen participate in this event. Loyal volunteers, who do not participate on a team, also seek Birdathon pledges. If you’d like to be involved contact Birdathon Chair Chandler Roberts at
2025 Birdathon – Birding for Bucks to Save Birds
2025 marks the 38th Amos Butler Audubon Birdathon and this year we have received the largest amount of grant requests in our history. The Birdathon Committee did an excellent job of selecting the most impactful grants with a heavy focus on research projects, habitat restoration and conservation projects. North American birds continue to face big challenges, like habitat loss, climate change and environmental pollutants. ABAS is working hard to address these challenges through this year’s grants. ABAS continues to work with long term partners like the American Bird Conservancy, Purdue University and the Marian University EcoLab while also building new relationships at Conner Prairie, Hamilton County Parks and Indianapolis Parks. We are thrilled about the grant requests we received this year and all of the great work being done throughout Central Indiana and beyond. Please help us raise the $40,256 necessary to fund the largest amount of grant requests in Birdathon history.
2025 – Make a Difference, Make a Pledge
Birdathon teams will be scouring the state during May, counting birds and asking donors to sponsor their efforts. If you don’t know a team member, you could choose to make a donation directly to the Birdathon. Either way, your dollars will go far to ensure the future of our Indiana birds. Donate online below! As always, thank you for the continued support from our Corporate Sponsors.


2025 Birdathon Donations Supported the Following:
Improving Migratory Bird Habitat in Colombia

The American Bird Conservancy – $15,000
Forestry Technician Funding
In 2024 the American Bird Conservancy once again far exceeded its goals in producing and planting native trees– 52,388–to create migratory corridors in the Central Andes Birdscape of Colombia. It also went beyond its goal to engage farmers to participate in conservation projects by engaging 102 farmers in total. With such great results, we will continue to support ABC and its local partner in Colombia, Vivo Cuenca, to create winter habitat for migratory birds such as Golden-winged, Cerulean, and Canada Warblers. All three of these species, which pass through Indiana on their way to their breeding grounds, are facing population declines due to habitat loss. This year ABC’s goal is to protect the existing forest fragments and improve habitat quality and connectivity by planting native trees within coffee-growing landscapes. ABC is seeking support from Amos Butler Audubon Society for 10 months of salary for one forestry technician, a crucial project role, as well as funds to support other project staff.
Research Projects

Indiana Audubon Society – $1,275
Echoes of the Night Sky – Program
This grant will fund Indiana Audubon’s “Echoes of the Night Sky” program that focuses on monitoring nocturnal bird migration across Central Indiana. This proposal aims to improve data collection, increase community participation, and provide a new, accessible platform for Hoosiers to engage with real-time nocturnal migration data.

Purdue University – $1,500
PFAS in Northern Saw-whet Owl Feathers Study
This grant will cover the cost of testing for the presence of per- and polyfluoroalkyl substances (PFAS) in Northern Saw-whet Owl feathers. PFAS is the term for a group of chemicals which are persistent in the environment and bioaccumulate in wildlife such as owls. Besides collecting data on Northern Saw-whet Owls to better understand this cryptic species, the project aims to provide undergraduate students with opportunities to gain experience with natural resources fieldwork in an accessible and educational environment.

Purdue University – $800
Study of Eastern Towhee Migration in Central Indiana
This grant will cover one year of data processing for 4 MOTUS towers installed by Purdue. The initial research impetus for the installation of these Purdue University Motus towers was to conduct an Eastern Towhee breeding phenology project. The Purdue University Motus towers have also collected data from birds banded at research stations across North America, traveling from locations like Montana, Quebec, Ontario, British Columbia, and Saskatchewan.

Indiana University Kokomo – $8,000
Northern Saw-Whet Owl Migration in Central Indiana
This grant will continue to fund a research project tracking and monitoring the migration of Northern Saw-Whet Owls at Eagle Creek Park. This project will take advantage of the MOTUS towers that are to be installed at Eagle Creek Park and Fort Harrison. The research will improve understanding of the biological and ecological needs of Saw-Whet Owls in urban environments and help with targeted habitat management.
Education & Outreach Projects

Indianapolis Parks & Recreation: Krannert Park – $1,681
Buying Binoculars for Programs and Events
This grant will fund the purchase of approximately 30 pairs of binoculars. The purchase will allow those interested in birding to have a resource to begin interacting with and learning about birds in the places where they live. The binoculars would be used for countless events, particularly those involving birdwatching at the park.

Conner Prairie Museum – $1,000
Black Birders Week
This grant will sponsor the second year of Black Birders Week (May 24-May 30). Black Birders Week is a dedicated week of virtual and in-person events and programs to uplift Black nature enthusiasts and highlight the visibility of Black birders in nature.
Preserving & Enhancing Local Habitats

Keep Indianapolis Beautiful – $2,000
KIB Native Plant Nursery
This grant will support the funding of the KIB Native Plant Nursery which will provide native plants for KIB Greenspaces throughout Marion County. KIB plans to grow 23 species of native plants and 4,000 plants total

Marian University Nina Mason Pulliam EcoLab – $2,500
Continued Community Involvement in Environmental Restoration
This year the grant will continue a multiyear, ongoing project using students to plant native trees and perennials in an urban gem. The restoration work will be led by the EcoLab Director, Dr. David Benson, EcoLab Science Director, Dr. Zachary Sylvain, and Taylor Lehman, the full-time Restoration Ecologist for the EcoLab. This year, the project will specifically focus on a lowland forest location used by Eastern Box Turtles and the prairie patches planned to be burned this spring (before planting). These plantings will provide excellent habitat for insects and the birds that feed on them in addition to improving the habitat for Eastern Box Turtles.

Hamilton County Parks & Recreation – $1,500
Habitat Restoration at Cool Creek Park
This grant will fund the work on restoring a three-acre riparian corridor inside the park with native plants.

Mud Creek Conservancy – $5,000
Restoration in the Blue Heron Nature Preserve
This grant will fund intensive restoration in the Blue Heron Nature Preserve along Mud Creek. This will specifically focus on 6 acres of the 12 acre reserve, where invasives have been removed and native plants need to be introduced.
2025 Birdathon Teams Species Counts
Of course, it wouldn’t be a Birdathon without our teams of intrepid birders. All teams give up regular meals and sleep to count the birds, all while raising donations to ensure the birds we value so highly will be around for the future. Check back here to see each team’s Big Day species count as they finish. If you’re interested in becoming a team, see the Birdathon Team Guidelines

Birdathon 2024
For over a quarter-century, the Amos Butler Audubon Society has been on a mission — a mission to promote the enjoyment and stewardship of the birds of Central Indiana. Birdathon 2024 (ending June 30, 2024) once again raised enough money to fund all the grants. The Noddy Little Gulls took top honors as both the fundraising and species champs with 149 species.
