I don't know that virus but perhaps you could try RDA to pick out viral 
DNA from avian genomic?

I direct you to _Cloning the Differences Between Two Complex Genomes_, 
Nikolai Lisitsyn, Natalya Lisitsyn, Michael Wigler, Science vol 
259:946-951 (1993).  They discuss the technique, Representational 
Difference Analysis, in which viral genomes can quickly be picked out of 
an entire, complex genome (as well as genetic rearrangements, deletions, 
etc).  It may serve to quickly pick out the virus you seek, even if you 
have absolutely no sequence information about it.
