Last week, John and I trapped and banded our first terns! We were thrilled to finally have the opportunity to see and work with these birds up close. But these amazing up close interactions did not come without a lot of hard work and preparation. The process of trapping and banding is very detailed and a complete understanding is needed to keep the terns happy and healthy.
Before we could start banding, Julia and Wayne had us practice on dummy birds. These dummy birds were composed of cardboard toilet paper rolls for bodies, Q-tips for legs, and duct tape for heads. Julia and Wayne informed us of the methods of handling and banding terns when out in the field and with their help we simulated banding on our dummy birds by using old bands. After we felt comfortable with banding we learned how to collected measurements from our birds. When a tern is captured we recorded the weight, wing length, and head and bill length of the tern. We got to see and use all of the tools used to take these measurements.
In preparation for trapping, we laid out all of our equipment out on the lawn and checked to make sure all of the traps had all their components and were functional. John and I spent some time getting used to setting up the traps and gripping the idea of the little quirks that makes the trapping process run a lot smoother. Once we were quick and efficient with setting up out traps we were ready for the real deal!
Our first trapping day was nerve racking and exciting! We had to find a balance when trapping and banding our terns that would enable us to work fast but also be gentle and thoughtful when handing the terns. As much as we wanted to take our time and soak up all the beauty, we had to act quickly and efficiently when banding the terns to minimize the amount of stress placed on the birds. I felt uneasy going into my fist banding experience; this wasn’t like the dummy birds we practiced on, the terns move around a lot more than the dummies and one wrong pinch on the band could harm the tern. But to my surprise banding my fist bird came natural to me and it went smoothly. I got to trap and band many more terns that day and I hope to do some more in the next few days.
So far we have trapped 19 COTE (common terns) and 16 ARTE (arctic terns) our goal is to have a total of 20 COTE and 100 ARTE by next week! Trapping and banding terns is important because it shows sight fidelity and survival rates of juveniles and adults.
