If you’ve driven by the Sam Noble Museum at any point since November, you may have noticed a rectangular, grass prairie sitting just behind the museum. No, no – we aren’t slacking on our chores. The tall brush houses several species of birds, some of which are extremely difficult to observe and track. That’s why a team of ornithologists hit the field last week to do a bit of bird banding before the March mowing.

It all began last fall, when Joe Grzybowski, ornithology research associate, discovered several species of sparrows hunting for food in the tall brush. One of these species, the LeConte’s sparrow, is an exceptionally secretive animal that researchers seldom stumble upon. In fact, only 3,000 LeConte’s sparrows have ever been banded, only one of which was recaptured at a later time.

Ornithologists engage in banding as a means of tracking species migration and monitoring populations. Each metal band, issued by the US Geological Survey Bird Banding Laboratory, contains a serial number and is sized for each species. Fortunately, Grzybowski has a banding permit and was able to lead the team through the process.
“A small conscious change in landscaping practices can help support a variety of wildlife,” said Tamaki Yuri, ornithology collection manager. “For example, the hawks we have seen around the field this winter are evidence of healthy populations of grassland birds and small mammals in the field.”

In just two hours, the team banded six sparrows of four different species – two LeConte’s, two Lincoln’s, one Song and one Savannah sparrows. Given the high winds and limited time, Yuri says she is pleased with the results. The team will use this information to track population growth for the area in coming years.
“If these birds know that the grasses exist, they will come back next year,” said Yuri, “and it is important to have more research on the LeConte’s Sparrow.”
