Curtiss started the tradition of naming their aircraft after birds started in 1919 with the Eagle, followed by the Oriole (also in 1919).
The Hawk tradition started in 1923 and in 1925, introduced a mailplane aptly named the Carrier Pidgeon.
Curtiss-Wright carried on the tradition with the exception of their SBC Helldiver in 1935, C-46 Commando in 1940, C-76 Caravan in 1943 and the XP-55 Ascender also in 1943.
Grumman also had a tradition of using waterfowl for their sea going aircraft, felines for fighters and type appropriate names for others, like Avenger, Skyrocket, Guardian, etc.
Then again, Hawker seemed to focus on birds, except when they were switching to various herbivores, or angry insects or storms and, well...nevermind.
