Info about the banded American Oystercatcher

On October 29th, I mentioned that when my friends and I were birding at Stone Harbor Point, we found an American Oystercatcher with leg bands. I reported the bands and after a few days, I was contacted about the history of this bird. From my photos of the bird, I knew its auxiliary marker (two yellow bands on the upper portion of each leg) read ‘J 1’ but I was not able to read the code on the silver, federal leg band. The banding lab was able to tell me that it is 1055-04556. All the east coast states coordinate banding efforts and each state assigns a different color for the auxiliary bands. New Jersey’s color is orange (which quickly fades to yellow as seen in my photos).

I was told that the bird was originally banded as a chick on Champagne Island, in the middle of Hereford Inlet (see map below) in 2005! This makes the bird 6 years old! In 2009, this individual was first reported nesting. It may have began nesting the year before that, since most American Oystercatchers take 3 to 4 years to start breeding, but no one saw it besting that year, so there is no way to know for sure.
