In the Spring
It is challenging to determine if the ruby-throats we see in spring are migrants or part of the local population. When researchers, like Nancy, recapture a recently banded bird, it is most likely local. A migrant is heading for its breeding grounds and isn't going to stay in one area for more than a week.
