For this next trip, I’m in the strange position of having to hope not to catch more than 23 juncos.
This has to do with those colored leg bands we put on the juncos in order to tell them apart. It seems that there is a general shortage of these: many colors are either entirely unavailable or backordered for an unknown amount of time. For the field season so far I have been limited to fewer colors than I expected, and I have been catching juncos faster than anticipated. By the end of our last trip, I was nearly out of color bands, not to mention distinguishable color combinations.
