Narrative:
I was cleared to take off from teb on runway 24 and my clearance was to climb and maintain 3000 ft via the teb 5 departure. The tower told me to turn right immediately after takeoff to a heading of 270 degrees and resume the teb 5 departure. The procedure calls for the pilot to maintain 1500 ft until reaching 4.5 DME and then climb to 3000 ft. When I reached 1500 ft a large flock of birds appeared in our windscreen and I had to take evasive action by pulling back on the yoke and hop-scotching over the top of them. I saw my altitude go up to 1920 ft and I immediately pushed the yoke forward and dumped the excess altitude and leveled at 1500 ft. About that time; departure called and told us to climb to 4000 ft and call ny departure and fly heading of 290 degrees. Teb departure and ny departure did not mention the altitude deviation to me nor did I to them.

Title: A C525 PLT LEVEL AT 1500 FT ON A TEB 5 DEP CLBED RAPIDLY TO 1920 FT AVOIDING FLOCK OF BIRDS. HE DSNDED BACK TO 1500 FT WITH NO COMMENT FROM ATC.
Narrative: I WAS CLRED TO TAKE OFF FROM TEB ON RWY 24 AND MY CLRNC WAS TO CLB AND MAINTAIN 3000 FT VIA THE TEB 5 DEP. THE TWR TOLD ME TO TURN R IMMEDIATELY AFTER TAKEOFF TO A HDG OF 270 DEGS AND RESUME THE TEB 5 DEP. THE PROC CALLS FOR THE PLT TO MAINTAIN 1500 FT UNTIL REACHING 4.5 DME AND THEN CLB TO 3000 FT. WHEN I REACHED 1500 FT A LARGE FLOCK OF BIRDS APPEARED IN OUR WINDSCREEN AND I HAD TO TAKE EVASIVE ACTION BY PULLING BACK ON THE YOKE AND HOP-SCOTCHING OVER THE TOP OF THEM. I SAW MY ALT GO UP TO 1920 FT AND I IMMEDIATELY PUSHED THE YOKE FORWARD AND DUMPED THE EXCESS ALT AND LEVELED AT 1500 FT. ABOUT THAT TIME; DEP CALLED AND TOLD US TO CLB TO 4000 FT AND CALL NY DEP AND FLY HDG OF 290 DEGS. TEB DEP AND NY DEP DID NOT MENTION THE ALT DEV TO ME NOR DID I TO THEM.
