San Jose City Hall’s celebrity falcons Clara and Esteban Colbert celebrated the dropping of their second egg of the season around 8:30am Wednesday morning. Clara started her sixth nesting season Saturday with the dropping of her first egg. Glenn Stewart, biologist and coordinator of UC Santa Cruz’s Predatory Bird Research Group, expects each egg to drop in 56-hour intervals until Clara and Esteban have a nest of three or four. Clara has had a series of lovers since she first built her nest on the 18th level of City Hall in 2007.
