2 Ravens working together are sometimes successful in stealing the prey from a Powerful Owls talons so I would think that a Bush Stone Curlew wouldn’t stand a chance against 3. They are pretty clever Corvids.

2 kilometers off course? Sounds like one of my drives.

Perhaps of a dubious relevance to Tony question but I have certainly seen Aust Raven try  to adjust their grip on a golf ball in flight and lose the ball.  Perhaps they were trying to swallow it?

 

I have also found balls at least 2 kilometres from the nearest course and have suumed Ravens have carried them and then dropped them.

hi Tony,

that's a very interesting observation I think, especially with the ravens eating on the wing!

Gidday all,

 

Saw three Australian Ravens being chased off by Bush Stone-curlew today in Townsville Common Cons. Park. Found two curlew eggs nearby. Ravens returned soon after and flew off with eggs. And seemingly swallowed them in flight as I tried in vain to focus and photograph the action. Certainly, two thorough sweeps of newly burned grass area (and therefore mostly charred open space) revealed no trace whatsoever of eggs. The ravens stayed in area, foraging on ground and calling from Leichhardt tree, which escaped with lower singeing from fire. Has anyone seen similar size birds swallow similar size eggs in flight?
