The composition of this list has remained pretty much static all these years. In fall 2009, American Robin surpassed Gray Catbird, unseating the catbird as the most common species for the first time since we started banding on campus. In fall 2008, Nashville Warbler inched out White-crowned Sparrow for 10th place.

*Spring banding largely discontinued after 2007.
**In order to compare different locations or years that may operate the same number of hours but with more or fewer nets, capture rate is calculated by “net-hours.” One net hour is one 12-meter net open one hour, or two 6-meter nets open one hour, etc.  This rate is often expressed per 100 net-hours for more manageable numbers.
