Initial trapping was conducted, utilizing three methods: a walk-in nest trap, Steele’s net, and rocket net. Following capture, all birds are fitted with an aluminium federal leg band. A uniquely numbered colored leg band is placed on the opposite leg of all birds. Finally, on most birds, a colored, uniquely numbered wing-tag is attached to each wing. These wing-tags make long-distance identification possible, particularly when it is difficult to see or read the leg bands. Wing-tags are color-coded based on the capture site’s proximity to either Reservoir.
Wing-tags can be seen from a distance, and the numbers on the tags are easily read with binoculars or sometimes even with the naked eye. All sightings are very important to this study. If you see a wing-tagged bird, contact Ken MacKenzie at Ken.Mackenzie@state.ma.us (508-792-7423 x313) or Dan Clark at Dan.Clark@state.ma.us (508-792-7423 x215) with wing-tag information.
