Doreen Cubie stopped by yesterday morning with the main goal of confirming the identity of my sixth year returning female Rufous originally banded in November of 2003. Unfortunately, she hovered all around the cage but refused to go in. She chased others from the cage, still refusing to go in herself. Finally, a Rufous entered the cage. Before I could close the door, a second one appeared at the door. The first instinct was to wait to see if she would enter as well but fear of both getting away won over and Selasphorus #2 is now wearing jewelry and can now be called Rufous #2.
Also banded was an adult male Ruby-throat with a badly injured bill. He's been around for a couple of months now, has been going through as molt, and was a very healthy weight.
The discussion of the pros and cons of banding probably should have been a thread of its own instead of being embedded the Arizona thread. That said, I just wanted to add that once the decision has been made to support it, it's very hard not to enjoy the opportunity to the fullest.
As a host, I haven't gone through a banding session where I wasn't a little concerned but I believe the potential for gain outweighs the little unsubstantiated concern. I've never had a hummer who's been banded not return, with one exception. That exception was a bird that had not been observed prior to the banding, at a time when my yard was over-saturated with birds. I had recorded 18 different birds in a two week period. My yard is only a third of an acre. Also, during that time, birds that hadn't been banded were observed that were not to be seen again indicating that sometimes they leave for reasons other than being handled, probably due to territorial disputes.
The potential for gain, as has been described by others, I see as a reason for taking part in the banding process (and, yes, it is an exciting opportunity to observe). We immunize children (and adults in some cases) against diseases they may not encounter. We pay for insurance that we hope we never need and we plan for the worst only so that we'll be prepared if it happens. My son appeared to suffer considerably more stress during immunizations and blood drawings than any hummingbird has during a banding session in my yard.
Research, including on hummingbirds, is needed to gain knowledge. You may not know when what you learn will be needed and/or how it will be applied but without it you can pretty much be sure that there will be plenty that you don't know.
