Narrative:
Initial clearance received from bog clearance delivery was to fly the 'guaymaral 4' departure, zip transition climb 17000 ft. Runway for takeoff runway 31L. During push out, we were advised runway 13L for departure. Receiving taxi clearance, we were told to taxi to runway 13R for takeoff. This also involved taxi routing changes due to pushout for runway 13L. The taxi clearance advised that runway 13R was 'due WX.' both copilot and I reviewed guaymaral 4 departure off runway 13R. There were rain showers in all quadrants, but mostly to the southeast. The 'due WX' statement did not register with us, as we looked at the sky. We took off on runway 13R. At 600 ft AGL, per 'guaymaral 4' the copilot started a left turn. Tower immediately advised that we turn right and fly the 'guaymaral 3.' we turned 180 degrees right climbing, I could not locate the ''guaymaral 3' departure in my part 2 nor in the FMS database. I did find the 'baso 3' departure, and it made sense that was what tower wanted. We were switched to departure control. As we climbed through 1200 ft, I requested direct to zip and received that clearance climbing to 14000 ft. In retrospect, the 'baso 3' departure would have kept us clear of most WX. We think that this is what tower was alluding to with the 'due WX' statement. This was only clear in hindsight. Questioning that statement, may have made it clear that tower expected and wanted a right hand turn after takeoff. The WX did not appear threatening enough to warrant any particular action on our part. I could not find any evidence of a 'guaymaral 3' departure that tower insisted that we had been cleared to fly. I think tower intended us to fly the 'baso 3.' we were very occupied with runway and taxiway changes that we missed any reference to a '3' in the clrncs. Supplemental information from acn 601844: I still do not know whether this was a mistake by the controller saying 'guaymaral 3 instead of baso 3' or if he said it exactly correct and we just heard what we expected to hear.

Title: B767 DEP FROM BOG IS CONFUSED WITH AMENDED DEP CLRNC AND MAKES WRONG TURN.
Narrative: INITIAL CLRNC RECEIVED FROM BOG CLRNC DELIVERY WAS TO FLY THE 'GUAYMARAL 4' DEP, ZIP TRANSITION CLB 17000 FT. RWY FOR TKOF RWY 31L. DURING PUSH OUT, WE WERE ADVISED RWY 13L FOR DEP. RECEIVING TAXI CLRNC, WE WERE TOLD TO TAXI TO RWY 13R FOR TKOF. THIS ALSO INVOLVED TAXI ROUTING CHANGES DUE TO PUSHOUT FOR RWY 13L. THE TAXI CLRNC ADVISED THAT RWY 13R WAS 'DUE WX.' BOTH COPLT AND I REVIEWED GUAYMARAL 4 DEP OFF RWY 13R. THERE WERE RAIN SHOWERS IN ALL QUADRANTS, BUT MOSTLY TO THE SE. THE 'DUE WX' STATEMENT DID NOT REGISTER WITH US, AS WE LOOKED AT THE SKY. WE TOOK OFF ON RWY 13R. AT 600 FT AGL, PER 'GUAYMARAL 4' THE COPLT STARTED A L TURN. TWR IMMEDIATELY ADVISED THAT WE TURN R AND FLY THE 'GUAYMARAL 3.' WE TURNED 180 DEGS R CLBING, I COULD NOT LOCATE THE ''GUAYMARAL 3' DEP IN MY PART 2 NOR IN THE FMS DATABASE. I DID FIND THE 'BASO 3' DEP, AND IT MADE SENSE THAT WAS WHAT TWR WANTED. WE WERE SWITCHED TO DEP CTL. AS WE CLBED THROUGH 1200 FT, I REQUESTED DIRECT TO ZIP AND RECEIVED THAT CLRNC CLBING TO 14000 FT. IN RETROSPECT, THE 'BASO 3' DEP WOULD HAVE KEPT US CLR OF MOST WX. WE THINK THAT THIS IS WHAT TWR WAS ALLUDING TO WITH THE 'DUE WX' STATEMENT. THIS WAS ONLY CLR IN HINDSIGHT. QUESTIONING THAT STATEMENT, MAY HAVE MADE IT CLR THAT TWR EXPECTED AND WANTED A R HAND TURN AFTER TKOF. THE WX DID NOT APPEAR THREATENING ENOUGH TO WARRANT ANY PARTICULAR ACTION ON OUR PART. I COULD NOT FIND ANY EVIDENCE OF A 'GUAYMARAL 3' DEP THAT TWR INSISTED THAT WE HAD BEEN CLRED TO FLY. I THINK TWR INTENDED US TO FLY THE 'BASO 3.' WE WERE VERY OCCUPIED WITH RWY AND TXWY CHANGES THAT WE MISSED ANY REF TO A '3' IN THE CLRNCS. SUPPLEMENTAL INFO FROM ACN 601844: I STILL DO NOT KNOW WHETHER THIS WAS A MISTAKE BY THE CTLR SAYING 'GUAYMARAL 3 INSTEAD OF BASO 3' OR IF HE SAID IT EXACTLY CORRECT AND WE JUST HEARD WHAT WE EXPECTED TO HEAR.
