Edge-tailed Eagle decline?

[Martin Butterfield <>]

Do wedgetails carry off lumps of carrion to feed chicks in nest?  If not, could a shortage of bunnies due to drought and/or calicivirus, for nestling food have led to reduced recruitment in the last couple of years?  

Reflecting on a drive from Canberra to Port Lincoln and back in June we saw very few large raptors (Black Kites, Wedgies)  on the Hay Plain.  At the time we tended to put that down to the Plain getting close to a cotton monoculture.

Does anyone have historical counts of WTEs before and after the impact of calici on rabbits? I’m wondering if we’re discussing a long term change, or something that’s a shorter time-frame response (to the drought?.....among many other possibilities, I realise).
