Does anyone have any information on the captive breedings of hawks?
I would be particularly grateful for any references to scientific papers
on the subject especially, although not exclusively,  with respect to 
goshawks (accipiter gentilis).  The kind of information I am seeking 
includes the dimensions and type of aviary, the materials used, whether they
are skylight-and-seclusion, the type of roofing, what facilities are provided
for the hawks, the feedstuffs used including nature of sources,  details
concerning the origins of the breeding stock eg: are they wild taken eyasses,
passage hawks, haggards or captive-bred themselves; were they manned and flown
or simply placed in the aviaries, any and everything really.

What I would like to be able to do is to establish a set of criteria under
which goshawks will breed in captivity.  Any information gratefully accepted.

Regards,

Jonathan M Spencer
