Narrative:
Cleared for takeoff runway 5 to maintain runway heading. Flock of waterfowl noticed at 11 O'clock position moving left to right at about 500 ft AGL after takeoff. Turned 40 degrees left to avoid hazard. Handed off to approach at about 600-700 ft AGL and approach controller came unglued when she learned I was 010 degrees and returning to 050 degrees. She instead asked for 260 degree heading due to incoming traffic from the north. Not having time to explain the reason for the heading change, and due to frequency congestion, I just kept the explanation to myself. I don't know if this scenario could have been prevented since the cause was birds flying around an airport, and on a waterway.

Title: PLT OF AN SMT TURNED TO AVOID A FLOCK OF BIRDS AFTER TKOF. THE DEV FROM THE ASSIGNED HDG WAS NOT CONVEYED TO ATC UNTIL AFTER THE HDOF TO DEP CTLR.
Narrative: CLRED FOR TKOF RWY 5 TO MAINTAIN RWY HDG. FLOCK OF WATERFOWL NOTICED AT 11 O'CLOCK POS MOVING L TO R AT ABOUT 500 FT AGL AFTER TKOF. TURNED 40 DEGS L TO AVOID HAZARD. HANDED OFF TO APCH AT ABOUT 600-700 FT AGL AND APCH CTLR CAME UNGLUED WHEN SHE LEARNED I WAS 010 DEGS AND RETURNING TO 050 DEGS. SHE INSTEAD ASKED FOR 260 DEG HDG DUE TO INCOMING TFC FROM THE N. NOT HAVING TIME TO EXPLAIN THE REASON FOR THE HDG CHANGE, AND DUE TO FREQ CONGESTION, I JUST KEPT THE EXPLANATION TO MYSELF. I DON'T KNOW IF THIS SCENARIO COULD HAVE BEEN PREVENTED SINCE THE CAUSE WAS BIRDS FLYING AROUND AN ARPT, AND ON A WATERWAY.
