Yes, all the OSPF routes do appear in 'ip route list'.

Static routes with the same 'via' as one of the problematic OSPF routes 
seem to cause a Netlink error when Bird starts up, but it doesn't repeat 
every 20 seconds like the OSPF routes.  The static routes appear in 'ip 
route list' and in 'show route'.  Config and log here:
