Water birds (according to Sonobe and Usui 1993) of the following orders: Pelecaniformes, Ciconiiformes, Anseriformes, Gruiformes and Charadriiformes.
Chlamydia spp were not detected in wild birds; however, 4 species (Chlamydia psittaci, Chlamydia pecorum, Chlamydia pneumoniae, and Chlamydia gallinacea) were identified among captive birds (Passeriformes, n = 20; Psittaciformes, n = 15; Rheiformes, n = 8; Falconiformes, n = 2; Piciformes, n = 2; Anseriformes, n = 1; Galliformes, n = 1; Strigiformes, n = 1).
Wild birds, especially waterfowl of the order Anseriformes (ducks, geese, and swans) are the natural reservoir of low pathogenicity avian influenza viruses, and since the HPAI outbreak at Lake Qinghai, People's Republic of China, in 2005, they have been suspected of playing a role as long-distance vectors of HPAI viruses (2,3).

Anseriformes, including Canada geese, usually have a higher relative number of circulating lymphocytes than heterophils with an H: L ratio between 0.
Although AIVs have been isolated from >100 species, several species from the orders Anseriformes (ducks, geese, and swans) and Charadriiformes (shorebirds) are thought to act as the reservoir community for AIV (6), primarily because AIVs have been most frequently isolated from these groups (9).

Wild waterfowl, primarily species in the orders Charadriiformes and Anseriformes (1), are natural reservoirs for type A influenza viruses.
Not only are there over 50 species missing from the book (the SACC list includes 1,352 non-passerines as of December 2006), but even recent understandings in higher level taxonomy are ignored, such as conjoining the Anseriformes and Galliformes (they are instead separated by unrelated orders).
