The paper I was trying to think of was

Lyon. R.H. 1997. Effects of an extensive wildfire on birds in far eastern 
Victoria. Pacific Conservation Biology. 3: 221-34.

This looked at recovery over three years post fire.  In essence, total 
bird abundance was reduced to 60% of initial levels but recovered within 
three years.  There were differences between habitats with heath having 
the greatest decreases and slowest recovery.

Honeyeaters and seed-eaters suffered the greatest initial declines.  The 
main loss of birds initially was of highly mobile species. Some species 
that feed on open ground increased quickly to levels greater than before 
the fire (Flame & Scarlet Robins, Buff-rumped Thornbills & Superb 
Fairy-wrens).  Except for fairy-wrens, these latter declined as shrubs 

Composition of remaining bird fauna after fire appeared to depend on 
resource availability rather than the capacity of species to survive the 
fire front.
