The Bird Class were a development of the Bulldogs with strengthened outside frames, of which a total of fifteen were built. A total of 121 Bulldogs were built new, with a further twenty rebuilt from
Duke Class locomotives. Thirty Bulldogs were later rebuilt as
Earl Class locomotives and renumbered 3265 (prototype conversion), 3200-3228.
History

No. 3312 ''Bulldog'' was built in October 1898, with curved outside frames, a domed parallel boiler with a raised
Belpaire firebox
The Belpaire firebox is a type of firebox used on steam locomotives. It was invented by Alfred Belpaire of Belgium in 1864. Today it generally refers to the shape of the outer shell of the firebox which is approximately flat at the top and sq ...
and a wrapper-type smokebox.
The boiler was a prototype for the parallel version of
Churchward's Standard No. 2 boilers.
[ ''Bulldog'' was originally classed as a variant of the Duke Class.]
In October 1899 no. 3352 ''Camel'' appeared with the final form of the parallel No. 2 boiler, domeless, with a raised Belpaire firebox and a circular drumhead smokebox supported on a curved saddle. A further twenty locomotives, nos. 3332 to 3351, were built between November 1899 and March 1900. Between May and December 1900 a second batch of twenty Camels (as the class were initially known) were built with straight-topped outside frames.[ These were numbered 3353 to 3372. A third batch, 3413 to 3432 were built between December 1902 and May 1903; these were the last to be built with parallel boilers.]
In September 1903 no. 3443 ''Birkenhead'' was built with a tapered Standard No. 2 boiler. The boiler was tapered only over the rear half of the barrel, and this type became known as the "half-cone"; a later version of the No. 2 boiler was tapered over three-quarters of the barrel. A further twenty-nine locomotives were built with the half-cone boiler between September 1903 and April 1904, bringing the class total to ninety-one.[
Between April and September 1906 thirty locomotives were built with the three-quarter coned No. 2 boiler.][ In March 1906, ''Bulldog'' was rebuilt with the same type of boiler, and the class now became known as the Bulldog Class. From October 1906 to January 1909 eighteen of the Duke Class were converted to Bulldogs by the fitting of No. 2 boilers. A further member of the Duke Class, no. 3273 ''Armorel'', had been fitted with a parallel domeless boiler in February 1902, thus becoming a Camel Class locomotive. It ran with tapered boilers of various types from April 1906.][
The Bird Class were a development of the Bulldog Class with deeper outside frames and a new type of bogie.][ Previously all outside framed bogies on GWR locomotives had been of the Dean centreless type. Churchward adapted a French design of bogie, as used on the de Glehn Atlantics, to produce a bar-framed bogie for his standard locomotives. This inside-framed bogie design was adapted to produce an outside-framed replacement for the Dean bogie.] The Birds were built in two batches; nos. 3731 to 3735 in May 1909 and nos. 3736 to 3745 from November 1909 to January 1910.[
This class were subject to the 1912 renumbering of GWR 4-4-0 locomotives, which saw the Bulldog Class gathered together in the series 3300-3455, and other types renumbered out of that series. The 3300-3455 series had previously contained locomotives of Duke, Badminton, Atbara, City and a number of Bulldog class locomotives.
No. 3320 ''Avalon'' was the first of the Bulldog Class to be withdrawn, in August 1929, followed by no. 3365 ''Charles Grey Mott'', withdrawn in January 1930.] The frames of 3365 were used to construct the first of the Earl Class, no. 3265 ''Tre Pol and Pen''. The last to be withdrawn was no. 3377 ''Penzance'' in January 1951.
All of the Bird Class survived into British Railways ownership, being withdrawn between April 1948 and November 1951, the last two being no. 3453 ''Seagull'' and no. 3454 ''Skylark''.
No Bulldogs were preserved; however the frames of no. 3425 survive under Earl
