Re: Walking dromaeosaurs

It's Lombard Street to a China orange that anyone is still interested in 
this thread... but anyway, here are two references on the topic.  They 
describe tail-wagging and wing-flashing as strategies used by insectivorous 
birds to drive insects out into the open:

Jackson, J. and M.A. Elgar (1993).  The foraging behaviour of the willie 
wagtail _Rhipidura leucophrys_: why does it wag its tail?  Emu 93: 284-286.

Keast, A., L. Pearce, and S. Saunders (1995).  How convergent is the 
American redstart (_Setophaga ruticilla_, Parulinae) with flycatchers 
(Tyrannidae) in morphology and feeding behavior?  Auk 112: 310-325.
