Re: Banded White-crowned sparrow

MC said "Any chance we can age this particular bird? The idea that it might be 7 years old (young?) is spectacular"

It also says a lot about site fidelity for breeders and the kind of plants/habitat these birds need. It’s useful info for when large developments, like Balboa Reservoir development un-house these sparrows. Where will they go? It would be an interesting study to tag the dozens of white-crowns at Balboa to see where they scatter and if they live after the coyote bush is replaced. Or, could they persist on the ornamental replacement plants?
