One of the advantages of having banded birds is that you can more easily notice if you may need to worry about genetic bottlenecks - for example, if all the peregrines in Manitoba this year were all Radisson (or Brandon) offspring, then the Manitoba population could be facing serious problems. It would be more of a concern perhaps if it were earlier in the program and there were fewer birds out there. After 30 years there are probably enough birds around that the anatum population in Canada and the US are fine and will be fine. By trying hard to make sure all our birds are banded, it makes the chances that an unbanded bird nesting somewhere in Manitoba is a Manitoba bird or a close relative less. Basically if we know who are birds are then any other birds aren't ours ...
But yes, so far this year we aren't doing too badly you are right ... :)

Not an issue actually. Because they were going to be moved to the nestbox they were going to be excluded from the transmitter project as we can't retrieve them safely when they are old enough to have a transmitter fitted. Downside is that not only can't they be tracked for the first couple of years by satellite, but we won't be able to track them at all without band numbers.
Having said that, if they are grounded after fledging and if they are re-releaseable, they will get bands and they will become candidates for a transmitter. We tend to have more groundings from the ledge than from the nestbox but still we'll just have to see. I'd prefer a boring fledgewatch with no groundings, but a soft, injury-free grounding even if it means being re-released with legbands and perhaps a transmitter runs a close second. I'm afraid I don't look forward to fledges from the ledge anymore. :-\

Guess this is, what is called a, "darned if you do, darned if you don't", scenario.
Bands are crucial to track these precious raptors, and it's a guessing game to find out, if, when, and where they may show up, with whom, and add to the family.
