49a West of America, keen on capturing bird like shot? (11) - INTRAVENOUS (Shot?)
This looks like 'Keen on' = INTO + 'Bird' = RAVEN + America = US, but why does it refer to the 'West' of America?
12d Be brilliant or a little bit third-rate around the edges (11) - SCINTILLATE (Be brilliant)
Help appreciated with the parsing for this.
