Given that the UCSD juncos have four times more broods of chicks from eggs every year than the mountain juncos, what are some other behaviors you think may have changed in the UCSD junco population since it separated from the mountain population?

Artificial lighting (from campus) triggered the release of sex hormones in some juncos earlier in the year than would occur naturally. This led those juncos to start their mating calls before flying back to the mountains. This resulted in attracting mates which led to having offspring on the UCSD campus. Juncos that did this ended up repeating this mating pattern and staying on campus year round.

There are many physical, behavorial and physiological trait differences between the mountain and UCSD Junco populations. This divergence happened in just 60 years of being separated from one another.

How could natural selection have changed the UCSD population over the last 60 years, so that there now is a higher proportion of individuals that have traits that give them a competitive advantage for producing more offspring in the UCSD environment then there were before?

Alleles missing from the gene pools of the mountain vs. UCSD Junco populations provide evidence that they aren't interbreeding (or if they are, the babies aren't surviving). We think these juncos should be considered separate species.

Excerpts of the methods, data, and findings that a group of scientists collected by sampling some of the birds in the UCSD population and some of the birds from the mountain populations, to try to determine if they are interbreeding will be investigated.
