The Michigan Nature Association recently hosted a project to track saw-whet owl migration at Lefglen Nature Sanctuary in Jackson County. The project leader and head owl bander was Selena Creed, who has years of experience banding raptors in the Mackinac Straits.
Saw-whet owl migration routes are well-documented along the Great Lakes shoreline, but the routes they take through inland Michigan are less understood. Given that the Sharonville State Game Area and surrounding wooded complex (which includes Lefglen) represents one of the largest contiguous habitat blocks in southeast Michigan, researchers believe it was likely they would be moving through here if they travel inland.
This year a total of 13 saw-whet owls were captured across five nights using mist nets and an audio lure. This is more than enough to prove that saw-whets are using Lefglen Nature Sanctuary and the larger surrounding habitat complex as an inland migration route through Michigan!
Selena and the team examined mostly female and hatch year owls, but were treated to a couple second year/after second year/male owls as well. One owl was a recapture that had been banded earlier this fall at Hillardton Marsh, Ontario – Selena states that recaptures are somewhat rare.
Thank you to Gary Hofing for taking very high-quality photos that provide great documentation of the banding process and measurements/data collected from each bird, including how they are aged using a blacklight to see wing molt pattern.
