Two questions about using Bird

Hi, After taking a little glimpse at the User's Guide, there're still two questions I still not quite understand: 1. Bird is a Linux daemon. I noticed that if I have installed Quagga, then when I try to install Bird, the operating system would require me to uninstall Quagga first. However there's another one called XORP, and it seems to be a platform or application for developing or studying routing protocol rather than a daemon. So can I intsall both XORP and Bird on a single Linux PC? Will they conflict with each other? 2. Does Bird provide a way to monitor OSPFv2? Like display the LSDB or display the routing table, etc. Thanks!
