I know that some people are not a fan of banding, and that some may think it is torturous for the birds. The fact remains that banding is, at this time, the best way to track/follow birds and compile data to prove to government officials and developers, that birds are using specific pieces of land, specific migration routes, and/or require specific habitat in order to survive.
There are different bands used for landbirds, waterbirds, raptors, etc., and studies are being done to find the most suited for special species.

Donnie Dipper's statement,
" Most all observatories do not keep a record of injury or mortality, during the netting process. Even your own observatory does not keep any public record of such events. The Bird Bander?s Guide states not to let the public know if a bird has died or been injured. The Spottswood paper was accepted by the banding community because it made them look good, but it is an good example of selective data usage, nothing more. " is incorrect.

Puget Sound Bird Observatory (PSBO) reports any and all injuries, no matter if pre-existing or a result of banding.

All our banders have taken hands-on-courses, and work conscientiously to maintain, and/or improve, safe handling of all birds. Wild entities may often have cancers, chemical imbalances (or pesticide/herbicide poisoning) that are the cause deaths. The few birds that I have seen that have died (and I have been banding since 2003), were either old, had lice/pox/ or some other disease, or were starving (fat of zero). I have never seen a death that was caused by fright (we let all birds go immediately if there are any signs of stress--and our banders have all been taught to watch for signs of stress), or bad handling. I do know of some birds that have been killed while in the nets by opportunistic predators --I have heard of wind causing some injuries, before the nets could be closed. No one,least of all someone who is actively working with a bird, likes to see or know about a bird death. It makes us feel bad, and can lead to misunderstanding about the effectiveness and ben!
eficial aspects of banding.


All banding stations are required to submit scientific data from each bird that is caught in the net--that includes any injuries and if any deaths. All the information is sent annually to the Bird Banding Lab, as part of the USGS requirement. There is no public posting, because most banding stations have a minimum of volunteers (here at PSBO, all work full-time elsewhere),
and the data would require long explanations to make any sense to the public...
(for example, a BCCH, AHY no CP, no BP, fat of 3--basically means that it is a Black-capped Chickadee,adult, not able to tell whether it is male or female (monomorphic birds can only be sexed during active breeding), and is actively feeding and healthy with a fat level of 3.] There is much more data taken for each bird, most of which seems immaterial to someone who does not actively study bird measurements. The collecting of this data takes about two minutes in the hands of an experienced bander.

PSBO reports the very small number of birds that might show injuries, including those that the bird may have had before touching the net, and all, if any, that might die per season.
That is part of our permit requirements.

And have no doubts about it--WE BAND THESE BIRDS TO HELP SAVE BIRDS IN GENERAL, AND SPECIFIC SPECIES IN PARTICULAR. And in order to band, before a permit is issued, we must have a valid, and approved by USGS, study to be issued a permit.

We don't get paid for this work. It is usually hot and buggy, or cold and chilly, and about four hours outside, usually without bathroom facilities. We do this because we LOVE BIRDS. AND WE WANT THEM TO SURVIVE. Having data to prove where birds are is vitally important. It make it harder for developers to ignore.

Pesticides, cats, window strikes, and tall structures cause thousand times more deaths per year then banding altogether has ever caused. People could focus on these dangers, as opposed to vilifying people who are working to protect and save birds in general, and some species in particular.
