There are plenty of birds and their corresponding genera have possess red color in their feather, all of them contain porphyrin in feather. e.g- bustards, goatsucker.
Kevin J. McGraw's book on bird coloration is indeed the leading reference. However, the statement that the red color in the bustards etc. is attributed to porphyrins is not (aside from the fact that goat suckers, bustards, owls have no real red in their plumage).
The porphyrins in the feathers of these birds is frequently more in their downy parts or under the wing on their primaries, is more prevalent when the birds are young, and contributes little, if anything, to the brown color of the feathers. In fact, most porphyrin, as seen by the porphyrin fluorescence under UV light conditions, is associated with the light-colored bands under the bird's wings, and elsewhere (see beautiful images, e.g., in: C. Scott Weidensaul, Bruce A. Colvin, David F. Brinker, and J. Steven Huy, Use of Ultraviolet Light as an Aid in Age Classification of Owls, The Wilson Journal of Ornithology 2011, 123(2), 373–377.) The porphyrins are coproporphyrin III (perhaps of type I also), uroporphyrin, and traces of protoporphyrin IX, and intermediary porphyrins (T. K. With, Int. J. Biochem. 1978, 9, 893-895.)
I do not know if a comprehensive list has been prepared of all the birds that contain this type of porphyrin in their feathers, or their biological function.
Red colors can be generated by porphyrins, in the form of their copper complexes. But this is rare. As far as I know, there is only one confirmed case of this, the pigment turacin (uroporphyrin III copper complex), which forms the red pigment in the flight feathers of several Turacos (banana eaters), and related species of birds (Musophagidae), firstly described by A. Church (Philos. Trans. 1869, 154, 627.) and confirmed multiple times since (e.g. R. E. H. Nicholas A, C. Rimington, Isolation of unequivocal uroporphyrin III. Biochem. J. 1954, 50, 194-201. or other works by Rimington, Fischer, or With).
As an aside, this is a wonderful demonstration for Ornithology students if you have a UV light and an owl at your disposal: https://eatmorecookies.wordpress.com/2015/02/27/owls-dont-just-hoot-they-also-glow/.
