The Purple Swamphen (Porphyrio porphyrio), also known as the African Purple Swamphen, Purple Moorhen, Purple Gallinule or Purple Coot, is a large bird in the family Rallidae (rails). From its name in French, talève sultane, it is also known as the Sultana Bird. It should not be confused with the American Purple Gallinule, Porphyrio martinica. The common name in New Zealand, used for the subspecies P. p. melanotus, is Pūkeko, which is the Māori name. The variant found in Samoa, P. p. samoensis, is called "manuali'i," meaning "chiefly bird" in the Samoan language.

Here are some of mine - all taken with a 40D, Tamron 70-200 f2.8 and either a Kenko Pro 300 1.4x DGx or a Kenko Pro 300 2x DG
Brent Goose: 203mm, f5.6, 1/1000, ISO 200, hand held (1.4x Tc)
PP: Crop, levels, curves, USM
Pied Wagtail: 400mm, f5.6, 1/500, ISO 1000, supported elbows on a shelf inside a hide (2x Tc)
PP: crop, levels, curves, USM
Bradfields Hornbill: 280mm, f6.3, 1/640, ISO 400, hand held (1.4x Tc)
PP: crop, levels, curves, USM
Herring Gulls: 400mm, f5.6, 1/800, ISO 400, monopod (2x Tc)
PP: levels, USM - got a feeling I reduced the exposure or highlights but can't remember exactly now.
I find the 1.4x Tc to work great with this lens in most conditions, and the 2x Tc is useable for me in good light.

What are we looking at? "2x" doesn't mean anything for a medium-small image. We need to know the pixel density of the camera, the amount of resizing you did (pixel ratio) and what lens, for this to mean much of anything.
