Crows are crowding Bay Area skies — why? | KQED
Why are there so many crows in the Bay Area? Are crows replacing other familiar birds, such as mockingbirds, blue jays and red-winged blackbirds? Is there a plan to reduce crow populations? John Marzluff, professor of environmental and forest sciences at the UW, and Kaeli Swift, a postdoctoral researcher in environmental and forest sciences, are quoted.

Seeing friends disappointed bums us out — the same might be true for ravens | PBS
Seeing someone else suffer a big disappointment can have a pretty damaging effect on your own morale. That’s definitely the case with people — and it might be true for ravens, too. Kaeli Swift, an animal behaviorist and corvid expert at the UW who was not involved in the study, is quoted.

Did crows actually make these gifts for the human who feeds them? | Audubon
Stuart Dahlquist had been feeding a family of American Crows in his backyard for more than four years before the crows gave him something back. At least, in his view. Kaeli Swift, a postdoctoral researcher at the UW studying crows, is quoted.

American and Northwestern crows began the speciation process at least once, but didn't finish it. When their ranges came back together, they resumed interbreeding. Can't tell American and Northwestern crows apart? Don't feel bad, because neither can they. https://www.biorxiv.org/content/early/2018/12/10/491654

Researchers study corvid speciation in restricted zone where crow hybrids thrive
Carrion crows and hooded crows are almost indistinguishable genetically, and hybrid offspring are fertile. Ludwig-Maximilians-Universitaet (LMU) in Munich biologists now show that the two forms have remained distinct largely owing to the dominant role of plumage color in mate choice.
