By Anne Brice, UC Berkeley News. For GSS Losing Biodiversity chapter 6. Excerpt: or the second year in a row, two peregrine falcons are pairing up again atop the Campanile, but this year they’ll be nesting in style. Experts have installed a permanent nest box with sides, back and a roof that will protect the couple and their soon-to-be growing family from sun, wind and rain. ...“In the pair-bonding period, starting near the end of December, the male does all the hunting and brings food to the female,” says Malec. “They call to each other a lot and bow to each other, touching beaks. They will perch close together and fly together.” If all goes well, the female will lay eggs between mid-February and mid-March. Once on the brink of extinction, peregrine falcons have made a remarkable comeback in the past few decades, and have begun moving from their natural cliff faces into urban areas, laying their eggs on skyscrapers and other tall buildings. The Campanile is prime real estate for peregrines, says Malec, with its great views and ample supply of pigeons to eat. Peregrines mate for life (although when one dies the other will readily take a new mate) and most pairs in the area stick around during the winter, defending their territory from other birds looking to move in on their turf....  http://news.berkeley.edu/2018/01/31/campanile-peregrine-falcons-new-nest-box/
