NEAR MISS DURING TAXI OUT FOR TKOF.

Narrative

WE PUSHED BACK FROM THE GATE AND RECEIVED A TAXI CLRNC FROM GND. GND TOLD US TO 'TAXI ALL THE WAY TO RWY 13R.' SO I READ BACK THE CLRNC; 'TAXI ALL THE WAY TO RWY 13R.' AS WE TAXIED OUT TO THE RWY THE CHKLIST WAS COMPLETED; AND THE CAPT CONFIRMED WITH ME THAT WE WERE CLRED TO TAXI ALL THE WAY AND TO CROSS RWY 17. I CONFIRMED WHAT WE HAD RECEIVED AND WE BOTH AGREED WE WOULD NOT NEED TO VERIFY OUR CLRNC AND WE WERE CONFIDENT THAT WE WERE CLRED TO CROSS RWY 17. AS WE TAXIED OUT TOWARDS OUR DEP RWY; I NOTICED A FLOCK OF BIRDS FLYING LOW FROM W TO E; AND ACROSS OUR DEP RWY. A FEW SECONDS LATER ANOTHER FLOCK OF BIRDS CAME ACROSS ALSO. SO I MADE THE STATEMENT THAT; 'THERE ARE A LOT OF BIRDS OUT TODAY; I'M GOING TO TURN ON THE RADAR' (I THOUGHT TO MYSELF); AND PROCEEDED TO TURN ON THE RADAR AND ADJUST THE TILT. JUST AS I HAD FINISHED WITH THE RADAR; THE CAPT JUMPED TOWARDS THE L IN A DUCKING FASHION AND I LOOKED AND SAW A CARAVAN TYPE ACFT APPROX 25-30 FT ABOVE US AND SLIGHTLY AHEAD OF US CLBING. THE ACFT HAD JUST TAKEN OFF ON RWY 17. THE ACFT ON RWY 17 WAS TAKING OFF ON AN UNASSIGNED RWY. THE GND AND TWR CTLR HAD NOT SEEN THE CESSNA GET ON THE WRONG RWY. WE WERE ON GND AND DID NOT HEAR THE TWR XMISSIONS. I HAD MY HEAD DOWN TURNING ON THE RADAR AND HAD NOT NOTICED WE WERE APCHING RWY 17; OTHERWISE I WOULD HAVE LOOKED TO CLR THE AREA. THE CAPT DID LOOK; AND COULD NOT SEE ANY TFC ON THE RWY.
