Greetings from Ship Island!

Bobby Brittingham here! As my time is coming to a close on Ship Island, I wanted a chance to post one more educational blog about our work before a farewell blog!

You may or may not have heard about “bird banding” before, it is an extremely common form of essentially tagging and releasing birds. Using specialized pliers, a small metal “C” shaped band is clamped shut around a bird’s tarsus (leg-like the shin bone equivalent to humans).

BBL size 2 band, with the identification number, these are the bands used on all of the birds on Ship.

The banding database provides a lot of information on each bird, where they have been seen, where they nest, where they migrate, or even if the bird is alive, as long as the bird’s band is seen and read correctly by another researcher. These bands are essential to distinguishing one bird from another to perform other research procedures or to distinguish which bird belongs to which nest. On Ship we had very late nesting, so Collin and I have been banding as many chicks as possible with our limited time so that these birds can be identified on where they go over the next year.

Bands vary in size and number of letters based on the size, type of band, and/or species of the bird. For the common terns on Ship Island, a single size 2 “BBL” band is placed around their right leg; these bands each have a unique 9 digit number.  These bands are then entered in an online database through the United States Geological Survey (USGS), and the “status” of a bird can be updated by individuals all over the world. For example, a tern was banded on Petit Manan this summer, and it has already been spotted by another researcher in Venezuela all the way in South America!

The chicks do not mind the bands as long as they’re put on correctly. When they are put on right, they even look stylish!

For me personally, it is the most fun protocol we perform out here, nothing beats the feeling of getting to meet hundreds of chicks that I have the privilege to watch over every day on this island. Not only that, but it is crucial for research purposes. With the late nesting that occurred this year on Ship, it will be interesting to see where these birds could have possibly gone earlier this year by resightings of the chicks that we band this summer. Be on the lookout for one more blog from the Ship Island crew later this week!
