Not Avocet or Teal.
Heron was in the PI on 12/7/41 so it cant be her. Cant be Swan who was also present at Pearl durring the attack.
Gannet, Lapwig, Sandpiper, and Thrush were all in the Atlantic.

That leaves only Partridge left as one of the class that had been converted to a tender in the Pacific at the time. Unless I missed another hint.
