This is Sundance Cody.
His father was killed by hunters and this left the pride open for a new male to take over, when a lone male finally took over he killed all the cubs but Suns mother cleverly hid him. A bird named Zuzu found him (she's Zazus mother) and told him to follow her if he wanted to live out the week as she knew his mother could not return. So Sun followed the bird and she took him to her nest where her own baby Zazu was. The bird named him Sundance Cody and when Zazu was old enough to fly, he and Sun both went out to find new home and both came accross the pridelands. Sun lived here untill he reached adulthood but Zazu stayed as Mufasa's Majordomo.
