You are invited to join us for Bird Banding at the Lake Jackson Sanctuary and offices for our monthly bird banding program at the GCBO headquarters on the third Saturday of each month from 8 a.m. to 12 p.m. Licensed bird banders and GCBO Research Associates Robert and Kay Lookingbill band at the sanctuary on a regular basis. Birds are captured for banding in very fine nylon nets known as “mist nets” because they are almost invisible in the environment. Captured birds are weighed and measured and their species, sex, and age are recorded. Each is fitted with an aluminum leg band with a unique number provided by the U.S. Fish & Wildlife Service and released unharmed. If the bird is captured again, the band provides the link to retrieve this history, which then provides important information on the routes used by migrating birds, their longevity, and general physical condition.
