That's so interesting.
Sorry for the threadjack here w/this question but I've always wondered something.
Can the banding be detrimental to the individual bird? (I've come to accept that it's probably necessary)
2 things come to mind:
- Can the stress of the banding itself shorten their lives or cause individual birds to have a heart attack for example?
- I realize this is subtle, but can the banding also have a detrimental effect on mating? Meaning might bird A (unbanded) not mate with bird B because bird B is banded (thus 'possibly' not normal or suitable for mating in the eyes of the bird)?
