It has recorded thousands of interactions between hundreds of the chattering birds and collected DNA to examine their genetic relationships. When Dr. Earl, then a graduate student in the lab, began crunching the data, she and her colleagues weren\u2019t shocked to see that birds largely helped relatives, the way an aunt or uncle may swoop in to babysit and give parents a break.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">But to their surprise, they found that starlings also helped nonrelatives, including when they might have helped family instead. Birds new to the flock helped those born within it, and vice versa.
