A group of visitors gathered early on Sunday, May 7, under the pavilion at Four Seasons Nature Preserve in Lake Geneva. Some arrived by 8 AM, but Wildlife Service Biologist Sarah Inyoue was there by 6:30 to set up the mist nets that would gently capture any birds moving through.

They become entangled in the fine mesh netting. The birds are carefully untangled and placed into soft cloth bags to be brought up to the measuring station.

After information is recorded, the bird is banded with a metal tag. Bird banding is one of the oldest and most important techniques used for studying and identifying birds.

giving a bird a drop of water while bird bandingSarah pays close attention to the behavior of the captured birds. This goldfinch seemed stressed, so she gave it a drop or two of water before releasing it.

Sarah gently blows on the bird’s feathers. She can see if there are fat reserves, and log this detail of information. 

The World Migratory Bird Day Events continued at Lost Valley Visitor Center, with a presentation by Stephanie Schmidt on Cranes. Stephanie is the Whooping Crane Outreach Coordinator for the International Crane Foundation. She presented information on Whooping Cranes as well as Sandhill Cranes.

Participants played games and learned about birds, earning points for all activities completed. Those that completed 14 events earned a plush, chirping bird.

Other activities included “Fill The Bill”, where visitors explored using different tools to see how birds use their specialized beaks to eat their favorite foods, a migratory ring toss game, “Jeop-bird-y”(a take-off from TV’s Jeopardy game), and itty-bitty bird walks through the forested grounds of Glacial Park.
