Chester have bred 44 lilac-breasted rollers and reared 24 chicks. 1996 2.2 1998 4.0 1999 3 2000 1.1.2(2 dns) 2001 4(4 dns) 2002 5(4 dns) 2003 3(3 dns) 2004 3.2.4(4 dns) 2005 8(3 dns) The pair in Tsavo aviary are too old to breed, I hope a new breeding pair will replace them when they are no longer with us.
I can't claim to have worked with these lovely birds, but I know someone locally who reared a brood of four in an ordinary back garden aviary some years ago. So they have potential to breed well enough to establish a captive population.
