The HA sequences from a falcon in Saudi Arabia, A/falcon/Saudi Atabia/6732-2/2007, is being released at Genbank. The sequence is virtually identical to the earlier wild bird sequence from Saudi Arabia, A/houbara bustard/Saudi Arabia/6732-1/2007, and differs at one positive, A328G.
Thus, this sequence is also the Uvs Lake strain of clade 2.2.3. This close relationship suggest the NA sequence from the falcon will also have G743A, which was in the wild bird NA sequence as well as all Uvs Lake sequences isolated since early 2007.
